Chagas disease carrier: Kissing bugs spreading in the US; how to identify these insects and stay safe

These bugs aren’t just a Latin America thing anymore. Researchers now label parts of the southern US—like Texas—as hypoendemic, meaning the kissing bug and the parasites it carries are here to stay. Since 2013, Texas alone has seen around 50 local human cases, plus up to 31% infection rates in dogs, and up to 50% of kissing bugs in some areas carry the T. cruzi parasite.
Kissing bugs have also been confirmed in 32 states, including California, Arizona, New Mexico, and more. And in Southern California, infections have already been spotted, raising concerns that the threat could move north toward the Bay Area.

Chagas is spread when a kissing bug bites you—usually near the face—feeds, then defecates. It might happen while you're sleeping. If you unknowingly scratch or rub that bite (ugh), the parasite Trypanosoma cruzi can slip into your bloodstream or get into your eyes or mouth. Though most US homes are well-sealed and the actual risk of transmission is low, rural and semi-rural areas with animal shelters, brush piles, and accessible entry points can be vulnerable.

Kissing bugs are flat, oval, and typically ½ to 1¼ inches long. They’re dark brown or black, with orange, red, or yellow stripes around the edges and a long, cone-like head—or “beak”—that’s tucked under until they feed.
They’re the size of your thumb’s tip and often mistaken for roaches or stink bugs. Nymphs (babies) look like smaller versions without wings.
Don’t kill it or touch it with your bare hands—that could increase exposure. Instead, carefully trap it in a jar or plastic bag (gloved), freeze it to preserve it, and contact your local health authority or extension service for identification.

Here’s your striker checklist:
Seal up cracks and gaps around windows, doors, baseboards, and attics.
Declutter—clear away woodpiles, brush, and debris near your home.
Reduce light at night—these bugs are drawn to lights.
Keep pet areas clean—wash bedding at high heat and vacuum often.
Use screens on windows or consider “bug lights” that are less attractive to insects
