Carpet Beetles are Welcome in my House if it Means not Having Bed Bugs!

By Marcia Anderson

Several months ago I received an e-mail from a city resident who was getting bites at night that she thought were from a spider. Large, and itchy, but with a burning sensation that told her they weren’t mosquito bites. The problem escalated until she had over 40 red welts on her legs. “I was getting groups of about 5-20 ‘bites’ every night, and my husband had none, and he wore boxers!

Some people are allergic to carpet beetles and some are not, however, almost everyone has some allergy to bed bugs. The pest company arrived, and upon inspection, no bed bugs were found, however, a few dead carpet beetles were discovered.
