Microscopic view comparing long hairs of bat bug vs short hairs of bed bug

You found a bug in the bedroom. You panicked. You paid an exterminator $1,000 to treat for Bed Bugs.

Two weeks later, the bugs are back.

You might have Bat Bugs.

The Invisible Difference

Under a microscope, a Bat Bug looks 99% identical to a Bed Bug. The only difference is the length of the hairs on their "neck" (pronotum). You can't see it with the naked eye.

Why Treatment Failed

Bed bugs live in your bed. Bat bugs live on bats... usually in your attic or chimney.

If you treat the bedroom but leave the colony of bats in the attic, the bugs will keep dripping down through the light fixtures and ceiling fans looking for food. They prefer bat blood, but if the bats leave (or migrate), they will settle for human blood.

The Fix

You don't need more poison in the bedroom. You need a wildlife exclusion expert.

  1. Evict the Bats: Install one-way doors so bats can fly out but not back in.
  2. Seal the Attic: Close the entry holes.
  3. Treat the Attic: Once the bats are gone, treat the attic insulation to kill the leftover bugs.
