Adults are just under a 1/4” long and are relatively flat, nearly as wide as long, and oval in shape compared to most other insects. The color is brown to reddish brown. The body may have short golden hairs and will exude a “sickening sweet” smell from glands on its body. There are many types of bed bugs and related insects.
Female bedbugs can lay over 500 eggs over a lifetime and each bed bug will molt or shed its shell five times as it grows and a blood meal is required for each molt. If blood meals become scarce, bed bugs can slow their life process until a blood meal source is found. The saliva of the bed bug may cause a swelling on most people when they are bitten but they do not leave a wound. Swelling may include redness in some sensitive people.
