We get a lot of calls from people who found a small bug in their bed and assumed the worst. Sometimes it’s a bed bug. Sometimes it’s a carpet beetle or a bat bug. Each one needs a different fix, so it pays to know the difference.

Bed bugs

  • About 1/4 inch long, the size of an apple seed
  • Flat, oval, reddish-brown body; rounder and redder after feeding
  • No wings
  • Feed only on blood, mostly at night
  • Found in mattress seams, headboards, couches, and recliners

Carpet beetles

  • Adults are smaller and rounder than bed bugs, with a hard shell and a spotted pattern of white, brown, and yellow
  • Adults can fly and are often found near windows
  • Larvae are fuzzy, brown, and bristly
  • They don’t bite or drink blood. They eat wool, fabric, pet hair, and lint
  • Their larvae’s tiny hairs can irritate skin, which can look like bites

Bat bugs

  • Look almost exactly like bed bugs; you usually need a magnifying glass to tell them apart
  • Have longer hairs on the area just behind the head
  • Live near bats in attics, chimneys, and wall voids
  • Will bite people when bats leave or are removed, often in homes near the attic
  • Treating for bed bugs alone won’t fix it. The bats have to be removed and the entry points sealed
