Triatomine bugs, also known as kissing bugs, can carry the parasite that causes Chagas disease which can be fatal. Because of the threat to health that these insects cause, it is best to know their behaviors and how to prevent a kissing bug infestation.

Where to Look for Kissing Bugs

Kissing bugs are typically found in South America, Central America and Mexico as well as in the United States. They prefer to stay outside under porches, in wood piles, under rocks, in dog houses, in brush piles, and in chicken coops. They can also find their way into homes by coming in through open windows, flying through the door, and crawling through gaps around doors.

They are mainly nocturnal and prefer to hide during the day. At night they come out of hiding to feed. In homes they may be found in pet bedding, under mattresses, and in nightstands. If you notice redness, swelling, itchiness, and other signs of an allergic reaction, particularly around the eyes and mouth, you may be dealing with kissing bugs. If they are in your home, you need to get them out quickly, especially since they have been so closely linked to Chagas.

Preventing a Kissing Bug Infestation

Preventing an infestation is as simple as keeping them out of your home. You can do this by sealing all gaps and cracks around your doors, walls, windows, and roof. Also seal cracks and holes that lead to the crawl space below your house and the attic. If you have any brush, wood, or rock piles near your home, move them as far away from the structure as possible.

Install screens on your windows and doors and repair any tears or holes as quickly as possible. Since lights can attract the insects, try to situate any outdoor lighting so that it is not close to the structure. At night, bring your pets inside.

Keeping your house clean as well as keeping pet bedding clean will also help keep them at bay. It doesn’t hurt to check periodically for the insects though.

Eliminating a Kissing Bug Infestation

In Latin America experts have been able to keep home infestations controlled by using synthetic pyrethroid sprays. While there are similar chemicals available in the U.S. none have yet been scientifically proven to be effective in eliminating the insects. The CDC recommends hiring a professional kissing bug control company, especially if you plan on using any insecticides.
