What Are the Signs of Bedbug Bites?

The first sign of bedbugs may be red, itchy bites on the skin, usually on the arms or shoulders. Bed bugs tend to leave straight rows of bites, unlike some other insects that leave bites here and there.

What are bedbugs? What do bedbugs look like?

Bedbugs are small oval non-flying insects that belong to the insect family Cimicidae, which includes three species that bite people. Adult bedbugs reach 5 mm-7 mm in length, while nymphs (juveniles) are as small as 1.5 mm. Bedbugs have flat bodies and may sometimes be mistaken for ticks or small cockroaches. Bedbugs feed by sucking blood from humans or animals. Adult bedbugs are reddish brown in color, appearing more reddish after feeding on a blood meal. Nymphs are clear in color and appear bright red after feeding. The wings of bedbugs are vestigial, so they cannot fly. However, they are able to crawl rapidly. Temperatures between 70 F-80 F are most favorable for bedbugs, allowing them to develop into adults most rapidly and produce up to three generations per year.
