During the day, bedbugs tend to hide away in furniture, floors, beds, and in wood or paper trash. They typically feed on human or animal blood at night, and most bites occur just before dawn. After taking their meal, which can last as little as three minutes, they drop off the host and crawl to a hiding place. Bedbugs can live for up to 10 months and can go without feeding for weeks.
The size of bed bug bites varies with a number of different factors. Bed bugs inject an anti-coagulant along with their saliva when they pierce the skin to take a blood meal. This anti-coagulant is mostly responsible for how a person reacts to the bite and determines the size of the bug’s bite. Since people will have various sensitivities to the bed bug’s bite, the size of the bite will vary, as well. Another factor that influences the size of a bed bug reaction is the number of times a person is bitten. Bite reactions of people bitten many times are also variable, and their response may be either more or less intense as the number of bites increases.
