Alphabetical List of Critters - Bed Bugs

Bed bugs are making a comeback in the U.S.  Adult bed bugs are brown, flat and about a 1/4-inch long, with a soft, rounded appearance. After a blood meal they are dark red, rounded (distended), and about 3/8-inch long. They usually come out at night or in darkened areas, and they typically hide close to their hosts.  When hiding places and hosts are few, however, they may be found almost anywhere there is a dark crack or crevice. Dark excrement spots of partially digested blood are often found where they rest. Cast skins will also be found, especially where infestations are heavy. [en Español]
