How Did I Get Kissing Bugs?

Bright porch and doorway lighting often lures kissing bugs inside homes. These insects feed on pets, so outdoor cats or dogs can also bring bugs inside.

How Do They Get Inside?

Kissing bugs can enter your home through:

  • Crawl spaces
  • Exposed cracks
  • Gaps around patio doors
  • Open chimney flues
  • Windows

How Serious Are Kissing Bugs?

Do They Bite?

Bites from kissing bugs are not usually serious and cause only mild pain and redness. These blood-feeding insects may target both humans and animals. Kissing bugs feed at night and their bites usually go unnoticed until the person bitten wakes up from their sleep.

Most people who have been bitten by these bugs were not aware of the bite and had little or no reaction. A small percent of people have an allergic reaction to the saliva of the bugs. These sensitive people have experienced itching, swelling, and other allergic symptoms.

Are They Dangerous?

Conenose bugs can carry the protozoa Trypanosoma cruzi, also called Chagas disease, through its feces. If the person rubs the feces into a break in the skin, he or she could become infected. Scratching the insect bite can introduce the feces into the body.

There have been very few cases of Chagas disease in the United States. Reports of the disease in Mexico or Central America cause concern in the southwestern United States.

Signs of Infestation

Kissing bugs are secretive and are not likely to be seen in the open during the day. They sometimes fly to lights at night. The only other signs would be their bites, but there are many other sources that can result in similar skin inflammation. A physician would need to be consulted to determine the cause of body signs.

Behavior, Diet, & Habits

Where Do They Live?

Kissing bugs live in many states across the country. They sometimes invade homes, especially in suburban and rural areas.

What Do They Eat?

Kissing bugs got their name early in the twentieth century because they are known to draw blood from the face of the victim. These bugs feed on blood from mammals such as:

The female bug lays eggs in the spring. The immature bugs (nymphs) need a blood meal every time they shed their skin and grow larger.
