What Are Kissing Bugs?
Kissing bugs may not be as well-known in Portland, OR as ants, spiders, or wasps, but they’re gaining attention nationwide as a potential health threat. These insects, which feed on the blood of humans and animals, might seem harmless at first glance. However, they can carry Trypanosoma cruzi, the parasite that causes Chagas disease, a serious condition that may lead to long-term heart and digestive issues if untreated.
Most common in the southern United States, kissing bugs are slowly becoming more recognized in other regions, especially as climate and housing conditions change. Portland’s mix of older homes, dense neighborhoods, and surrounding natural areas can create opportunities for kissing bugs to find shelter. While they aren’t as widespread here as in Texas or Arizona, local homeowners should understand how to identify these pests, the risks they pose, and how to keep them out of their living spaces. This guide will walk you through the essentials so you can better protect your home and family.
How to Identify Kissing Bugs
Kissing bugs are flat, oval-shaped insects measuring about ¾ to 1¼ inches long. They are usually dark brown or black with orange or red stripes along the edges of their bodies, which helps distinguish them from similar insects. Their cone-shaped head and slender antennae also set them apart from beetles or other harmless bugs.
These insects hide in dark, sheltered places, often close to where people or animals sleep. Common hiding spots include cracks in walls, under porches, inside woodpiles, dog houses, and areas where rodents or pets nest. In Portland, older homes with crawl spaces, unsealed gaps, or cluttered backyards may offer them easy hiding places. Properties near greenbelts, the Willamette River, or heavily wooded areas may also face higher risks because of abundant wildlife that can attract kissing bugs.
Being able to identify them correctly matters, as cone-nose bugs and some beetles are often mistaken for kissing bugs. If you suspect you’ve seen one, capturing a clear photo or contacting a pest professional can help confirm what you’re dealing with.
Why Kissing Bugs Are a Health Concern
The nickname “kissing bug” comes from their tendency to bite people around the mouth and eyes while they sleep. The bite itself is not usually painful, but the health risk lies in what some of these bugs carry.
Certain kissing bugs are infected with Trypanosoma cruzi, the parasite that causes Chagas disease. Transmission happens when infected bug feces enter the body through the bite wound, eyes, or mucous membranes. Not every kissing bug carries the parasite, but those that do can pose a significant risk.
Chagas disease can cause mild flu-like symptoms in the short term, but its long-term effects are much more serious. Left untreated, it can damage the heart, lead to digestive problems, and even cause sudden cardiac arrest years after exposure. While the disease is more common in Latin America and the southern U.S., growing awareness shows it’s not confined to those areas alone. For Portland residents, caution is important—especially for households with pets, outdoor animal housing, or properties with conditions where kissing bugs might thrive.

Protecting your home from kissing bugs starts with reducing entry points and eliminating habitats that attract them.
- Seal your home. Caulk cracks and gaps around windows, doors, foundations, and rooflines to block insect access.
- Maintain screens. Repair or replace damaged window and door screens to keep bugs outside.
- Reduce clutter. Clear away woodpiles, brush, and outdoor debris that provide hiding spots near your home.
