Pests In Wisconsin

Bed Bug in Wisconsin, what are Bed Bugs?
Bed bugs are small reddish-brown insects. They’re
about 3/16 inch long (size of an apple seed) and easily
visible to the naked eye. They are wingless, but are
fast crawlers. Their bodies are very flat with slender
legs and antennae. Nymphs (immature bed bugs)
resemble the adults–but are smaller and often lighter
in color. Bed bugs feed on the blood of humans
during the night or in darkness and crawl away to hide
in nearby cracks, crevices, recesses of furniture
(especially mattresses and head boards), clutter,
electronic equipment, and walls of the home during
the day
