If you’re not allergic to them, their bite won’t hurt you. If you are allergic to them, you may have a mild or severe reaction. However, this isn’t their biggest danger. The most dangerous part of kissing bugs is what they do at night.

The biggest concern is Chagas disease. Up to over 1 million Americans have been affected by this. It generally happens when the bugs bite around the mouth or enter body cavities while one sleeps. It is not the bug itself but their feces that can kill.

ChiggersView in gallery

What Do Chiggers Look Like?

Chiggers look like small, reddish ticks. They are also found in grassy areas and where one is found, a thousand more can appear. When you get bit by one, you probably are covered in them. So check under your clothes before going inside.

Thankfully, unlike ticks and mosquitoes, chiggers do not carry any diseases. They are fairly harmless and only cause irritation and red marks when you are bitten. Still, try to keep them out of your home when you can.
