Dependable Pest Control

What Is Bourbon Virus?

Bourbon virus is a rare virus believed to spread through the bite of an infected tick. It was first identified in 2014 in Bourbon County, Kansas, and cases have since been identified in the Midwest, South, and along the East Coast.

News reports have frequently described Bourbon virus as “incurable” or “untreatable.” A more medically precise explanation is that there is currently:

• No vaccine to prevent Bourbon virus disease
• No specific antiviral medicine that cures it
• No widely available commercial test routinely used by doctors

Because Bourbon virus is viral, antibiotics such as doxycycline—which are commonly used to treat certain bacterial tick-borne illnesses—do not treat the infection. Patients may instead receive supportive care, including fluids and treatment for pain, fever, nausea, or other symptoms. Severe cases may require hospitalization.

What Symptoms Can Bourbon Virus Cause?

Symptoms reported among people diagnosed with Bourbon virus have included:

• Fever
• Severe fatigue
• Headache
• Body aches
• Rash
• Nausea
• Vomiting

Laboratory testing may also show unusually low white blood cell or platelet counts. These symptoms can resemble ehrlichiosis, Lyme disease, and other tick-borne illnesses, making Bourbon virus difficult to recognize without specialized testing.

Anyone who develops fever, rash, unusual fatigue, severe headache, or flu-like symptoms following a tick bite or outdoor exposure should contact a healthcare professional and mention the possibility of tick exposure.

Which Tick Is Associated With Bourbon Virus?

The lone star tick, scientifically known as Amblyomma americanum, is the tick most closely associated with Bourbon virus.

Adult female lone star ticks are recognized by the distinct white spot in the center of their backs. Males have scattered pale markings but do not have the female’s single prominent dot. Nymphs are much smaller—approximately the size of a poppy seed—and can be difficult to detect on the skin.

Unlike ticks that remain still and wait for a passing host, lone star ticks are active host-seekers. They may move across the ground toward people or animals after detecting movement, heat, or carbon dioxide.

Pennsylvania identifies Bourbon virus among the pathogens associated with lone star ticks. The state reports that lone star nymphs are generally active from May through early August, while adult activity is strongest during the spring and early summer.

Is Bourbon Virus a Concern in the Delaware Valley?

The confirmed New York case does not mean that a Bourbon virus outbreak has been declared in the Philadelphia area. However, it reinforces the importance of tick awareness throughout the Northeast.

Lone star ticks are established in parts of Pennsylvania, and Pennsylvania health officials have reported that neighboring states have detected Bourbon virus in environmentally collected lone star ticks.

New Jersey considers the lone star tick one of the state’s two tick species of greatest public-health importance, along with the blacklegged or deer tick.

People do not have to travel deep into the wilderness to encounter ticks. Exposure can occur in:

• Residential yards
• Parks and walking trails
• Wooded property edges
• Tall grass and weeds
• Leaf litter
• Brushy landscaping
• Areas frequently visited by deer
• Outdoor workplaces
• Properties bordering vacant or overgrown land

Ticks may also be carried into yards and buildings by dogs, wildlife, clothing, landscaping materials, and outdoor equipment.

Bourbon Virus Is Not the Only Lone Star Tick Concern

The lone star tick is associated with several additional medical concerns, including ehrlichiosis, tularemia, Heartland virus, Southern tick-associated rash illness, and alpha-gal syndrome.

Alpha-gal syndrome is a potentially serious allergy to a sugar found in most mammalian meat and products derived from mammals. It may develop after certain tick bites and can cause delayed allergic reactions after eating beef, pork, lamb, or other mammalian products.

Not every lone star tick carries a disease-causing organism, and not every tick bite leads to illness. Nevertheless, preventing bites remains important because it is impossible to determine simply by looking at a tick whether it is carrying a pathogen.

How to Reduce the Risk of Tick Bites

When spending time outdoors:

• Use an EPA-registered repellent labeled for ticks.
• Apply permethrin products to clothing and gear according to the label, never directly to the skin.
• Wear long pants, socks, and closed shoes in wooded or brushy areas.
• Wear lighter-colored clothing so crawling ticks are easier to see.
• Stay near the center of maintained trails.
• Avoid brushing against tall grass, shrubs, and vegetation whenever possible.

After outdoor activity:

• Check your entire body for ticks.
• Examine the waistline, underarms, behind the knees, groin, scalp, hairline, and behind the ears.
• Check children and pets carefully.
• Shower soon after returning indoors.
• Examine backpacks, shoes, jackets, and outdoor equipment.
• Place dry clothing in a dryer on high heat to help kill ticks that may be hiding in the fabric.

Young ticks can be extremely small, so a thorough inspection is essential.

Making Your Property Less Attractive to Ticks

Tick prevention also begins with the conditions around a property.

Ticks thrive in shaded, humid areas with leaf litter, dense vegetation, tall grass, brush, and wildlife activity. Reducing these conditions can help limit the areas where people, pets, and ticks are likely to come into contact.

Property-maintenance measures may include:

• Keeping grass regularly trimmed
• Removing accumulated leaves and brush
• Cutting back overgrown vegetation
• Increasing sunlight around heavily shaded areas
• Separating recreational spaces from wooded edges
• Moving outdoor furniture and play equipment away from dense vegetation
• Discouraging deer and rodents from remaining near occupied areas
• Maintaining a clean buffer between lawns and wooded property edges

No single step can guarantee a tick-free property. Effective tick management generally requires several coordinated measures.

How Evans Pest Control Approaches Tick Management

Evans Pest Control uses an Integrated Pest Management approach to help reduce tick activity around homes, businesses, apartment communities, outdoor work areas, and other properties.

Rather than treating every part of a property in the same manner, an IPM-based tick program focuses on the locations most likely to support tick activity.

This may include:

Property inspection

Technicians evaluate shaded vegetation, leaf litter, brushy borders, fence lines, groundcover, wildlife routes, outdoor gathering areas, and transitions between maintained lawns and wooded environments.

Tick identification

Identifying the species and life stage can help determine when ticks are most active, where they are likely to be found, and which environmental conditions may be contributing to their presence.

Habitat recommendations

Customers may receive practical recommendations concerning grass, vegetation, leaf litter, woodpiles, wildlife activity, yard edges, pet areas, and other potential tick habitats.

Targeted treatment

Where appropriate, products may be applied according to label directions in carefully selected areas where ticks are likely to rest or encounter hosts.

Monitoring and seasonal prevention

Tick activity changes with species, weather, habitat, wildlife, and time of year. Follow-up service can help address seasonal activity and newly developing conditions.

Professional tick management can reduce tick populations and the likelihood of encounters, but it cannot eliminate every tick or guarantee that a bite or illness will never occur. Personal precautions and routine tick checks remain essential.

Awareness Is the Best First Line of Defense

The first confirmed Bourbon virus case in New York is not a reason to panic, but it is a serious reminder that the variety and geographic reach of tick-borne diseases continue to change.

Residents and businesses throughout Philadelphia, Bucks County, Montgomery County, Delaware County, Chester County, South Jersey, and the surrounding Delaware Valley should remain alert—particularly during warm-weather months when people, pets, and outdoor workers spend more time in tick habitat.

Are giant rats real? Learn how large city rats can become, why some rats appear enormous, and how Evans Pest Control uses IPM to protect businesses.

Anyone who has lived or worked in a large city has probably heard a story about an enormous rat.

It may have been described as “the size of a cat,” seen running behind a dumpster, crossing an alley, disappearing into a sewer opening, or dragging food across a sidewalk. Photographs and videos can make these encounters look even more dramatic, especially when the rat is close to the camera or carrying something recognizable, such as a piece of food.

But are giant city rats actually real?
The answer is a little more interesting than a simple yes or no.

The Rats Most Commonly Seen in Cities
The rat most often associated with streets, sewers, alleys, basements, loading areas, and commercial trash facilities is the Norway rat, also called the brown rat or sewer rat.

Norway rats have heavy bodies, blunt noses, relatively small ears, and tails that are usually shorter than the combined length of the head and body. A typical Norway rat measures approximately 13 to 18 inches from its nose to the end of its tail and weighs around 11 ounces, although individual animals naturally vary.

The other major structural rat is the roof rat, also known as the black rat or ship rat. Roof rats are generally slimmer and lighter than Norway rats. They have pointed noses, larger ears, and tails that may be longer than the head and body combined. They are also skilled climbers and are more likely to use trees, utility lines, attics, ceiling voids, upper storage areas, and elevated structural spaces.

In the Philadelphia region, an especially large rat seen at ground level, near a dumpster, around a foundation, or emerging from a burrow is more likely to be a mature Norway rat than a mysterious giant species.

Why Do Some City Rats Look So Enormous?
A normal rat can look surprisingly large during a brief encounter.
The tail adds considerable length

When people estimate an animal’s size, they often include its long tail without realizing it. A Norway rat with a body measuring several inches may approach a foot and a half in total nose-to-tail length.
When the tail is stretched across the pavement, the rat can appear much longer than expected.

Perspective can exaggerate the animal
A rat filmed close to a phone camera may appear much larger than people, vehicles, trash containers, or other objects farther behind it. Low-angle security cameras can create a similar effect.
A familiar object can also influence perception. A rat carrying a slice of pizza or standing beside a small drain opening may look gigantic, even though the object itself may be smaller than it appears in the image.

A mature Norway rat has a heavy build
Norway rats are not delicate-looking animals. They have thick bodies, coarse fur, strong legs, and broad heads. A mature, well-fed Norway rat can look considerably more substantial than the small laboratory rats or pet rodents most people picture.

Raised fur and posture change its appearance
A startled rat may arch its back, raise its fur, crouch, or turn sideways. These positions make the body appear taller and wider.
Poor nighttime lighting may also blur the edges of the animal, making it difficult to judge where the body ends and the shadow begins.

Are There Really Giant Rat Species?
Yes. Large rat-like rodents do exist.
The Gambian pouched rat, native to Africa, is one of the largest animals commonly called a rat. Florida wildlife authorities report that it may measure approximately 20 to 35 inches from its nose to the end of its tail, with an average weight of about three pounds. These animals have large cheek pouches and are very different from the Norway rats normally encountered in American cities.
Other unusually large rodent species have also been documented in different parts of the world. That does not mean populations of three-foot African pouched rats are secretly living beneath Philadelphia streets.
The important distinction is between a genuinely large rodent species and an unusually large-looking member of a common urban species.

What About Reports of Cat-Sized Subway Rats?
Stories of rats weighing eight, ten, or even fifteen pounds have circulated for decades. These accounts are usually difficult to verify and may involve exaggerated size estimates, distorted photographs, mistaken identity, or fictional illustrations.
An ordinary city rat can certainly be large enough to startle someone. However, an eight- to fifteen-pound “subway rat” would be dramatically larger than the normal size range of the Norway rat.
When someone reports a rat “the size of a cat,” a pest-management professional is more interested in the surrounding evidence than the witness’s size estimate.
Where was it seen? Was it near garbage, a sewer opening, a loading dock, a construction site, a vacant lot, a commercial kitchen, or an overgrown area? Did it enter a burrow or structural gap? Were droppings, gnaw marks, tracks, rub marks, or nesting material present?
Those clues tell us much more about the actual problem.

Why Larger Rat Sightings Occur Around City Buildings
Urban properties can provide nearly everything rats require: food, water, shelter, warmth, and concealed travel routes.
Commercial dumpsters, spilled food, damaged trash bags, grease accumulation, standing water, improperly stored ingredients, dense vegetation, cluttered storage areas, and structural deterioration can all make a property more attractive to rodents.
Construction and demolition may also disturb established burrows and travel routes. Rats that previously remained hidden may suddenly appear in alleys, yards, parking areas, loading zones, or neighboring buildings as they search for new shelter.
Philadelphia’s Department of Public Health maintains a rat-reporting process for residences and public parks. Rat activity involving food businesses is directed to the city’s Office of Food Protection, reflecting the importance of responding appropriately when rodents are seen around commercial food environments.
One Large Rat May Point to a Larger Problem
The size of the rat is usually less important than the conditions that allowed it to be there.
A single sighting may reveal:
• An accessible food or water source.
• A damaged door sweep or utility penetration.
• Burrows around a foundation or landscaped area.
• Gaps beneath loading doors.
• Openings around plumbing, conduit, rooflines, or vents.
• An established travel route between neighboring properties.
• Poorly managed trash or outdoor storage.
• Activity inside wall, ceiling, basement, or crawlspace voids.

Professional inspectors look for droppings, fresh gnawing, tracks, burrows, runways, greasy rub marks, nesting material, damaged packaging, and sounds inside structural spaces. Rats frequently follow the same protected routes, leaving repeated signs along walls, pipes, beams, fences, foundations, and equipment lines.

For a business, waiting until rats are seen during operating hours can allow a manageable exterior problem to develop into an interior infestation.

Why Rodent Control for Businesses Requires More Than Bait
Placing a few traps or bait stations may reduce visible activity, but it does not automatically correct the conditions supporting the infestation.
If food remains accessible, doors remain damaged, openings are left unsealed, or neighboring activity is ignored, new rodents may replace the ones removed.

That is why Evans Pest Control uses an Integrated Pest Management, or IPM, approach for commercial rodent control.
IPM is a structured pest-management process that combines inspection, identification, monitoring, prevention, sanitation, exclusion, and carefully selected control methods. The goal is not simply to react to individual rodents. It is to understand why activity is occurring and reduce the conditions that allow it to continue. The EPA describes IPM as an environmentally sensitive approach that emphasizes monitoring, prevention, appropriate action thresholds, and targeted controls selected for effectiveness and risk.

Evans Pest Control’s IPM Approach for Businesses
Every commercial property presents a different set of conditions. A restaurant, warehouse, apartment building, school, health-care facility, office, retail store, and manufacturing property should not receive an identical rodent-control plan.
An Evans Pest Control commercial rodent program may include several coordinated steps.

Detailed inspection and identification
Technicians inspect interior and exterior areas for active rodents, droppings, burrows, gnawing, rub marks, tracks, damaged materials, nesting sites, and probable entry points.
Correct identification also matters. Norway rats, roof rats, and mice differ in their behavior, nesting locations, travel patterns, and preferred environments.

Monitoring and documentation
Monitoring devices and service records help determine where activity is occurring, whether conditions are changing, and which corrective measures are producing results.
This is especially valuable for businesses with multiple departments, storage rooms, tenant spaces, loading areas, kitchens, utility rooms, or exterior waste zones.

Exclusion recommendations
Rodent exclusion focuses on closing the routes animals use to enter the structure.
Potential entry points may include gaps around utility pipes, damaged masonry, openings beneath doors, roof penetrations, vents, loading-dock gaps, broken screens, and spaces where different building materials meet.
Durable repairs are important because rats can gnaw through materials that are too soft or poorly installed.

Sanitation and environmental corrections
Food residue, overflowing waste, standing water, clutter, dense vegetation, and improperly stored goods can sustain rodent populations.
Evans Pest Control can identify contributing conditions and work with property managers, maintenance teams, employees, and vendors to improve sanitation and reduce harborage.

Targeted rodent control
When active control is required, methods are selected according to the property, infestation level, rodent species, safety considerations, and applicable product directions.
The objective is to place control devices strategically along actual rodent travel routes—not simply scatter equipment throughout the building.

Follow-up and ongoing prevention
Rodent pressure can change with weather, construction, neighboring properties, trash conditions, deliveries, landscaping, and seasonal activity.
Continued inspection and monitoring help identify new activity before it becomes a larger operational problem.

Do Not Wait for the “Giant Rat”
A business does not need to see a mythical, cat-sized rat before taking action.
One dropping, one damaged package, one burrow, or one unexplained grease mark may be the first visible sign of a developing problem. Addressing the issue early is usually more effective than waiting until rodents are being seen by employees, customers, tenants, or inspectors.
Whether the rat looked average, unusually large, or absolutely enormous, the right response is the same: identify the species, locate the source, remove contributing conditions, close entry points, and implement a professional control plan.

If you've ever looked up while walking onto your porch and noticed a gray, papery nest hanging beneath the roof, you've probably discovered the work of a paper wasp.

In the latest episode of What's The Buzz?, Bobby BEE explains why these fascinating insects choose sheltered locations around our homes and what homeowners should know about them.

Why Paper Wasps Love Overhangs
Paper wasps naturally look for places that protect their nests from the elements. Roof overhangs, porch ceilings, decks, soffits, and eaves provide an ideal environment because they shield the colony from heavy rain, direct sunlight, and strong winds.

These protected locations also allow the wasps to fly in and out easily while keeping developing larvae safe inside the nest.

Are Paper Wasps Beneficial?
Many people are surprised to learn that paper wasps actually provide an important service in nature.

They hunt caterpillars, flies, and other insects to feed their young, helping reduce pest populations in gardens and landscapes. In many ways, they're natural pest control specialists.

When Should You Be Concerned?
Although paper wasps are generally less aggressive than yellowjackets, they will defend their nest if they believe it's threatened.

A nest located:
• Above a front door
• Near a garage entrance
• Under a deck
• Above children's play equipment
• Near patios or outdoor seating

can increase the chance of accidental encounters.

Don't Remove Nests Yourself
Attempting to remove an active paper wasp nest without the proper equipment can result in multiple stings.

If a nest is located where people regularly walk or gather, it's safest to have it professionally evaluated.

Summer Isn't Just Insect Season — Rodents Remain Active Too

When most homeowners think about summer pest problems, they picture mosquitoes, ants, or wasps. What many people don't realize is that rats and mice remain highly active throughout the summer months, creating significant concerns for homes, businesses, restaurants, warehouses, apartment communities, and commercial facilities throughout Philadelphia and the surrounding Delaware Valley.

We understand that rodent control is one of the most serious and technically demanding services in the pest management industry. Unlike many common pests, rodents can spread disease, contaminate food supplies, damage property, and create significant health risks for occupants. Effective rodent management requires far more than simply placing bait stations or traps—it demands experience, inspection expertise, and a comprehensive Integrated Pest Management (IPM) approach.

Why Rodent Activity Increases During Summer

During the summer months, rodent populations are often at their highest levels. Warm temperatures, abundant food sources, active construction projects, outdoor dining, and increased human activity provide ideal conditions for rats and mice to thrive.
In urban and suburban environments throughout Philadelphia, rodents are commonly found around:
• Restaurants and food service facilities
• Apartment complexes and multi-family housing
• Warehouses and distribution centers
• Manufacturing facilities
• Schools and healthcare facilities
• Residential neighborhoods
• Construction sites
• Trash and recycling storage areas
As populations increase, rodents begin searching for new food and harborage opportunities, often leading them into homes and businesses.

The Serious Risks Associated with Rodents

Rodent infestations should never be viewed as a nuisance issue alone. Rats and mice can pose substantial health and property risks.

Rodents are capable of contaminating food products, food preparation surfaces, storage areas, and inventory through urine, droppings, nesting materials, and direct contact. They can damage electrical wiring, insulation, drywall, stored goods, packaging materials, and building infrastructure.

For commercial facilities, like restaurants, rodent activity can cause disasters:
• Failed inspections
• Regulatory violations
• Product contamination
• And serious reputation damage
For homeowners, rodent infestations can lead to expensive repairs, persistent odors, contamination concerns, and ongoing health risks for your family.

Why Effective Rodent Control Requires Experience

Rodent control is often one of the most misunderstood services in pest management.
Many infestations persist because only the symptoms are treated while the underlying causes remain unaddressed. A technician may remove visible rodents, but if entry points, food sources, nesting locations, and environmental conditions are not identified and corrected, the infestation will often return.
Successful rodent management requires an understanding of:
• Rodent biology and behavior
• Species identification
• Travel patterns and harborage areas
• Food source analysis
• Building construction
• Exclusion techniques
• Sanitation improvements
• Monitoring strategies
• And long-term prevention
Every property presents unique challenges. What works for a single-family home may be completely ineffective in a warehouse, restaurant, healthcare facility, or apartment building.

Evans Pest Control's Integrated Pest Management (IPM) Approach

Evans Pest Control technicians believe that rodent control is built around proven Integrated Pest Management (IPM) principles.
Rather than relying solely on baiting programs, our technicians focus on identifying and correcting the conditions that allow rodents to survive and reproduce.
Inspection
Every successful rodent program begins with a detailed inspection.
Our technicians evaluate:
• Entry points
• Structural vulnerabilities
• Food sources
• Moisture issues
• Harborage locations
• Rodent activity patterns
• And interior / exterior risk factors
This investigative process helps determine how rodents are entering the structure and what conditions are supporting their activity.

Exclusion

One of the most important components of rodent management is preventing access.
Even a small opening can allow mice or rats to enter a structure. Evans Pest Control technicians identify exclusion opportunities and provide recommendations to reduce rodent entry and movement.

Monitoring

Professional monitoring allows technicians to evaluate activity levels, identify travel routes, and determine whether populations are increasing or decreasing.
Monitoring data helps ensure treatment decisions are based on actual evidence rather than assumptions.

Targeted Control Measures

When treatment is necessary, Evans Pest Control utilizes targeted control strategies appropriate for the specific property and infestation.
These may include:
• Professional trapping programs
• Exterior rodent stations
• Interior monitoring devices
• Mechanical controls
• And population reduction strategies
Each program is tailored to the facility and its unique requirements.

Sanitation and Environmental Improvements

Rodents depend on food, water, and shelter. Addressing these resources is essential for long-term success.
Our technicians work with property owners, facility managers, and maintenance teams to identify environmental improvements that help reduce rodent pressure and support lasting results.

Residential Rodent Control
For homeowners, rodent activity often begins in:
• Attics
• Basements
• Crawlspaces
• Garages
• Utility penetrations
• Exterior foundation areas

Homeowners may notice scratching sounds, droppings, gnaw marks, unusual odors, or pet behavior changes before actually seeing a rodent.
Our residential rodent programs focus on identifying the source of the problem, reducing current activity, and helping prevent future infestations.

Commercial Rodent Control

Commercial rodent management presents an entirely different level of complexity.
Restaurants, warehouses, healthcare facilities, schools, industrial sites, and property management organizations often require ongoing monitoring, documentation, compliance support, and proactive prevention strategies.
Evans Pest Control has extensive experience working with commercial facilities throughout the Delaware Valley and understands the importance of maintaining a professional, documented, and effective rodent management program.

Protecting Philadelphia Homes and Businesses

Rodent control is not a one-size-fits-all service. Every infestation presents unique challenges that require careful evaluation, technical expertise, and a strategic approach.
Whether you're protecting your family's home, managing a restaurant, operating a warehouse, or overseeing a commercial property, professional rodent management can help reduce risks, protect property, and provide peace of mind.
At Evans Pest Control, our experienced technicians utilize Integrated Pest Management techniques and proven rodent control strategies to help residential and commercial customers throughout Philadelphia, Bucks County, Montgomery County, Delaware County, and Southern New Jersey maintain healthier, safer environments.

When you think of insects with bold yellow and black coloring, bees, wasps, and hornets probably come to mind immediately. But have you ever wondered why so many different insects share the same striking color pattern?

The answer is one of nature's most effective warning systems.

Nature's Warning Sign

Bright colors often serve as a warning. It’s called “Aposematic Coloration”. These color patterns tell predators, "Stay away."

Yellow and black is one of the most recognizable warning combinations in nature. These contrasting colors are highly visible against flowers, grass, trees, and even the sky, making them easy for birds, reptiles, and other predators to spot.

Over millions of years, predators have learned that many yellow-and-black insects can sting, bite, spray defensive chemicals, or simply taste unpleasant. As a result, many animals instinctively avoid insects displaying these colors.

The Original Yellow-and-Black Insects

Bees are among the most famous examples. Honeybees and bumble bees use their stingers to defend themselves and their colonies. Their bright coloration acts as a visual reminder to predators that approaching them may have consequences.

Wasps and hornets take this warning system even further. Species such as paper wasps, yellowjackets, and bald-faced hornets aggressively defend their nests when threatened. Their distinctive yellow-and-black patterns help advertise their ability to sting before a confrontation ever occurs.

In many cases, the warning coloration helps prevent attacks, benefiting both the insect and the predator.

The Great Pretenders

One of the most fascinating aspects of nature is that some insects wear yellow and black even though they cannot sting at all.

Hover flies, for example, are harmless pollinators that closely resemble bees or wasps. This phenomenon is known as “Batesian Mimicry”, where a harmless species gains protection by imitating a more dangerous one.

To a hungry bird, it's often safer to avoid anything that looks like a wasp rather than risk finding out the difference.

Some moths, beetles, and even certain flies have evolved similar appearances, creating an entire community of insects that benefit from nature's warning system.

Not Every Yellow-and-Black Insect Is a Threat

While many yellow-and-black insects deserve a wide berth, not all of them pose a danger.

Many bees are important pollinators that help support gardens, farms, and natural ecosystems. Hover flies are beneficial insects that feed on nectar and pollen while helping control certain pest populations.

Understanding the difference between beneficial insects and true pests can help homeowners make informed decisions when they encounter insects around their property.

When Yellow-and-Black Insects Become a Problem

During the spring and summer months, stinging insects often build nests around homes, sheds, decks, roof overhangs, playground equipment, and landscaping features.

While a single bee or wasp visiting flowers is usually nothing to worry about, large colonies located near entrances, patios, or areas where children and pets play can become a safety concern.

Paper wasps frequently build umbrella-shaped nests beneath eaves and porch ceilings. Yellowjackets often establish colonies underground or inside wall voids. Hornets may construct large aerial nests in trees or shrubs.

If these insects begin nesting close to your home or business, professional removal is often the safest solution.

Evans Pest Control Can Help

The technicians at Evans Pest Control understand the important role insects play in our environment. Our approach focuses on identifying the species involved and recommending the most appropriate course of action.

Whether you're dealing with wasps under an eave, yellowjackets in the ground, hornets in a tree, or simply trying to identify a mystery insect, our team can help protect your family while respecting beneficial pollinators whenever possible.

If you've discovered a nest or have concerns about stinging insects around your property, contact Evans Pest Control for a professional inspection and expert guidance.

Our Spring Perimeter Maintenance Program is designed to stop mosquitoes before they become a problem—protecting your home, yard, and outdoor living spaces.

Evans Pest Control Comprehensive Property Inspection
We begin with a detailed inspection to identify:
• Active and potential breeding zones
• Areas of standing or trapped water
• Shaded harborage zones where mosquitoes rest
This allows us to customize treatment specifically for your property.

Installation Of Mosquito Pots (Larval Control)
We strategically place mosquito control pots attract egg-laying mosquitoes and neutralize larvae before they mature.
Why this matters:
Instead of just killing adult mosquitoes, we stop the next generation from ever developing—breaking the lifecycle at its source.

Natural & Targeted Barrier Treatments
We apply pet safe, natural-based and low-impact treatments around:
• Property perimeters
• Bushes, shrubs, and shaded areas
• Under decks and along fence lines
• Patio and outdoor living spaces
These treatments create a protective barrier that:
• Repels mosquitoes
• Reduces resting populations
• Minimizes exposure while remaining effective

Water Source Management & Recommendations
We don’t just treat—we advise and manage. Our expert technicians point out:
• Drainage issues
• Hidden water collection areas
• Maintenance steps you can take to reduce risk
This proactive guidance significantly enhances long-term results.

Why Early Season Treatment Is Critical

Take a moment to watch — it could help protect your home.

Winter is going bye bye… for now - As temperatures begin to rise homeowners in the Delaware Valley enjoy longer days, blooming trees, and more outdoor activities. Unfortunately, spring also marks the beginning of peak pest activity throughout the region. Many insects and rodents that had remained dormant during the winter months become active again, searching for food, water, and shelter—often insisting they have an open-door policy to your home and business.
Evans Pest Control considers spring to be the most important time to initiate pest control measures. It is the busiest season of the year because pests emerge rapidly once temperatures consistently stay above freezing. Understanding which pests become active during the spring—and why—can help homeowners stay ahead of infestations.

Why Spring Brings Increased Pest Activity
During winter, many pests slow down or enter a dormant state. As temperatures rise, insects are biologically triggered to reproduce, forage for food, and establish new colonies. Increased moisture from spring rains and thawing soil also creates ideal conditions for pests to thrive.
Philadelphia’s mix of historic row homes, dense neighborhoods, aging infrastructure, and nearby waterways like the Delaware and Schuylkill Rivers creates an environment where pests can easily move between outdoor habitats and residential structures.
This combination makes spring the start of the annual population surge.

Common Spring Pests in Philadelphia
Several pests tend to appear more rapidly as the weather warms. Some are simply nuisances, while others can cause structural damage or create sanitation concerns.
Ants
Ants are one of the first pests’ homeowners notice in the spring. As colonies expand, worker ants search for food sources inside kitchens, pantries, and basements. Small cracks in foundations, window frames, and doorways allow ants to enter homes easily.
Certain species, like carpenter ants, can also damage wood structures if infestations go untreated.
Termites
Spring is the beginning of termite swarming season in the Philadelphia region. Winged termites leave mature colonies to establish new ones, often appearing near windows or light sources.
Because termites feed on wood from the inside out, infestations may exist long before visible damage appears, making professional inspections important during this time of year.
Rodents
Mice and rats remain active throughout the winter but often expand their search for food and nesting areas during the spring. Philadelphia’s older housing stock and interconnected structures provide numerous entry points.
Rodents can spread bacteria, contaminate food, and damage wiring and insulation.
Stinging Insects
As spring progresses into late April and May, wasps, hornets, and yellow jackets begin building new nests. Early detection is important because nests grow rapidly throughout the summer.
Small early-season nests are much easier to remove than large colonies later in the year.
Spiders and Other Crawling Insects
Spiders, centipedes, and other crawling insects become more visible in spring as they follow the insects they prey on. Their presence often indicates other pest activity nearby.

Moisture: A Major Spring Pest Factor
Spring rains create moisture conditions that attract pests. Damp soil, clogged gutters, leaky pipes, and poor drainage around foundations can encourage pests like termites, ants, and cockroaches to move closer to a structure.
Basements and crawlspaces are particularly vulnerable because they provide cool, dark, and humid environments that many pests prefer.

Preventing Spring Pest Problems
While pests are a natural part of the environment, homeowners can reduce the risk of infestation by taking a few preventative steps:
• Seal cracks around doors, windows, and foundations
• Keep food sealed and clean kitchen areas
• Trim vegetation away from the exterior of the home
• Store firewood away from the house
• Maintain gutters and proper drainage
• Schedule seasonal pest inspections
Proactive pest management helps catch problems before they grow into larger infestations.

Why Early Season Pest Control Matters
Spring is the time when pest populations begin to grow, which means early treatment can prevent larger infestations later in the year.
Addressing pests early can:
• Prevent structural damage from termites or carpenter ants
• Stop colonies from expanding indoors
• Reduce the likelihood of summer infestations
• Protect the health and comfort of your home
Many homeowners choose seasonal pest control programs to maintain protection throughout the year.

Protecting Philadelphia Homes
Philadelphia homes—especially historic properties and older row homes, can have hidden gaps, aging foundations, and shared structural spaces that make pest control more challenging.
Professional pest control technicians understand the unique conditions of Philadelphia neighborhoods, surrounding suburbs, and South Jersey communities, allowing them to identify risks that homeowners might not notice.

As temperatures begin to warm across the region, the destructive Termite quietly enters peak season. While many homeowners worry about ants or mosquitoes in the spring, one of the most expensive threats to homes in the Delaware Valley is already at work long before it’s visible.

Termites cause billions of dollars in property damage every year in the United States, and much of that damage occurs before homeowners even realize they have a problem.
Evans Pest Control is always geared up for Termites, and peak season seems to start earlier every year. Must discoveries by the homeowner start like this: the homeowner notices a few flying insects near a window or discovers damaged wood during a renovation. Unfortunately, by that point the termites may have been feeding inside the structure for months—or even years.

The Silent Destroyers Of American Homes
Termites are often called “silent destroyers” because they feed on wood from the inside out. Unlike many other pests, termites usually stay hidden behind walls, under flooring, and inside structural beams where they remain undetected.
Subterranean termites—the most common species in the Northeast—live underground in large colonies and build mud tubes that allow them to travel between soil and the wood inside your home while staying protected from light and air.
Inside a home, termites feed on:
• Structural framing
• Floor joists
• Wall studs
• Wooden beams
• Subflooring
• Deck supports
• Trim and molding
Over time, this feeding can weaken structural integrity, sometimes causing thousands of dollars in repair costs before the damage is discovered.

Why Spring Is Peak Termite Season
Late winter and early spring mark the beginning of termite swarming season. During this time, mature colonies produce winged termites called swarmers whose purpose is to leave the colony, mate, and establish new infestations.
In our region, including Philadelphia, Bucks County, Montgomery County, and South Jersey—swarming activity often begins as early as February and March, especially during warmer winters.
Homeowners may notice:
• Flying termites near windows or light sources
• Piles of discarded wings on windowsills
• Small mud tubes on foundation walls
• Wood that appears blistered, soft, or hollow
Seeing swarmers indoors is often the first visible sign of a nearby colony.

Why Many Homeowners Miss The Signs
Termites are masters at staying hidden. Most infestations occur behind walls, under flooring, or in crawlspaces, making early detection difficult without a trained eye.
Some of the most common reasons infestations go unnoticed include:
• Damage occurs inside wood where it isn’t visible
• Swarms can happen quickly and may be mistaken for flying ants
• Mud tubes may be hidden behind siding or foundation landscaping
• Crawlspaces and basements are rarely inspected closely
By the time damage is visible, termites may have already been feeding for several seasons.

The Cost Of Waiting
Unlike many other pest issues, termite damage may not be covered by homeowner’s insurance because it is considered preventable through proper maintenance and inspection.
That means early detection is critical.
A professional termite inspection can identify:
• Active infestations
• Conditions conducive to termites
• Moisture issues that attract colonies
• Structural vulnerabilities around foundations and crawlspaces
The earlier termites are discovered, the easier—and less costly—it is to eliminate the colony and protect the structure.

What Homeowners Can Do Right Now
There are several preventative steps homeowners can take to reduce the risk of termite activity:
• Keep wood and mulch away from the foundation
• Repair moisture problems and leaks
• Maintain proper drainage around the home
• Avoid storing firewood directly against the house
• Schedule periodic professional termite inspections
While these steps help reduce risk, they cannot eliminate termites entirely, especially in regions where subterranean termites are common.
