Entomology (Study of Bugs)/Black carpet beetle


Hello Eric I just read a response you made to Mark from 2010 regarding this insect however I have a dog who's fur gets everywhere & I've found now 2nd bug in my bed where my infant now sleeps I've had this bed for about 7yrs lived in this house for 3 and my question is does it eat ear wax? And if I sprinkle down some 7 dust or boric acid on the floor behind the bed & window seal will that kill them


Without seeing at least an image of the insect in question (preferably a specimen), I am not inclined to offer information that may not be accurate or specific to the creature.

That said, nothing is absolute.  Insects that enter the human ear make headlines specifically *because* they are such incredibly rare events.  It is not even worth worrying about.

I do not recommend chemical treatments of any kind for carpet beetles. Keeping the house clean is the best prevention, along with properly storing vulnerable linens and clothing, food.  Here are my posts on carpet beetles and the larger but related larder beetle:




Those links should give you all the information and tips you desire.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
