Bed bugs are small parasitic insects that feed on human blood. While they are a public health concern, bed bugs are not known to transmit disease through their bites. The history of bed bugs dates back to ancient Egypt. Bed bugs have been a household pest issue for more than 3,300 years! They were first brought to the United States by early colonists, where they thrived for many decades. However, by the 1950’s, bed bugs had been all but eradicated in the developed world, thanks to the availability of new pest control products, coupled with the widespread use of vacuums and washing machines which helped to control the spread of infestations in living spaces.
Several factors led to the resurgence of bed bugs beginning in the late 1990’s: increased international travel, more targeted pest control products and methods, and a lack of public awareness about pest prevention methods.
Bed bugs use a small tube-like structure called a proboscis to pierce the skin and drink a person’s blood. The pests are most active when humans are asleep, during the night and early morning.An estimated one in five Americans have personally dealt with a bed bug infestation or knows someone who has encountered the pests.
What do bed bug bites look like?
Some people don’t develop noticeable symptoms from bedbug bites. When symptoms do develop, the bites tend to be:
- red and swollen, with a dark spot at the center of each bite
- arranged in lines or clusters, with multiple bites grouped together
Bedbugs can bite any part of your body. But they’ll usually bite areas of skin that are exposed while you sleep, such as your face, neck, arms, and hands. In some cases, the bites may develop into fluid-filled blisters.

If a bedbug bites your skin, you won’t feel it right away because the bugs excrete a tiny amount of anesthetic before feeding on people. It can sometimes take a few days for symptoms of bed bug bites to develop.
Bedbug bites often become noticeably red and swollen. Multiple bites may appear in a line or cluster in a small area of your body. The bites tend to be itchy. They may cause a burning sensation.If you have bedbugs living in your home, they may not feed every single night. In fact, they can go multiple days without eating. It might take a few weeks to realize that the bites are part of a larger pattern.
