Kissing Bugs & Chagas Disease: A Growing Concern In The Delaware Valley

At Evans Pest Control, serving the Philadelphia area and the wider Delaware Valley, we pride ourselves on keeping families safe from pests that threaten health and comfort. One insect that is gaining attention among researchers, entomologists, and public health officials is the kissing bug—a blood-sucking pest now known to transmit Chagas disease, which has become endemic in parts of the United States.

What Are Kissing Bugs?
Kissing bugs, also called triatomine bugs, are nocturnal insects that feed on the blood of humans and animals. They get their nickname from their habit of biting near the mouth and eyes while people sleep. Although they may resemble common pests like stink bugs, kissing bugs are a distinct species that pose serious health risks.

How To Identify A Kissing Bug:
• Size: ½ to 1 inch long.
• Shape: Elongated body with a cone-shaped head.
• Color: Dark brown or black with orange or red markings on the edges.
• Behavior: Attracted to lights at night and often enter homes through cracks, open windows, or poorly sealed doors.

If you see an insect matching this description, exercise caution and contact the professionals at Evans Pest Control for proper identification.

Chagas Disease: A Silent Threat
The kissing bug is a vector for Trypanosoma cruzi, the parasite that causes Chagas disease. Infection occurs when the bug defecates near the bite wound, and the parasite enters the body.
• Early symptoms can include fever, fatigue, body aches, and swelling around the bite site.
• Chronic infection may not show symptoms for years but can eventually lead to serious heart and digestive complications.

According to researchers, Chagas disease—once thought to be confined to Central and South America—has now become endemic in the U.S., with confirmed cases in states across the South, Midwest, and even the East Coast. While not every kissing bug carries the parasite, the risk is real and growing.

Why The Delaware Valley Should Be On Alert
Though kissing bugs are more common in southern states, occasional sightings have been reported in Pennsylvania and surrounding regions. With increasing awareness from entomologists and public health experts, homeowners in the Philadelphia area are urged to stay informed.

How To Protect Your Home
Preventing kissing bugs requires a combination of vigilance and pest control strategies:

• Seal Entry Points – Repair cracks around doors, windows, and foundations.
• Secure Screens – Make sure window and door screens fit tightly with no tears.
• Reduce Outdoor Lighting – Lights attract kissing bugs; consider using yellow “bug lights.”
• Keep Pets Safe – Bring pets indoors at night, as they can also be bitten.
• Professional Pest Control – Evans Pest Control offers expert inspections and targeted treatments to reduce risks from vector-borne pests.

Entomologists emphasize the importance of early detection and professional management. Because kissing bugs can easily be mistaken for other insects, professional identification is critical.
