Entomology (Study of Bugs)/Bug found on bed



We found this on our bed.... Please advise what this May be and how we need to proceed?


Thanks for including the image with your question.

This appears to be the larva of a Black Carpet Beetle, genus Attagenus .  Because over 70% of the questions I receive have to do with carpet beetles, I am pasting my standard responses here:

Here is more information:







Yours would be the "Varied Carpet Beetle," Anthrenus verbaci , or a closely-related species.

One of these days I will put together my own fact sheet....Keeping your home clean of accumulating shed hair and skin flakes from people and pets always helps.  Storing dry food (including dry pet food) in glass, metal, or durable plastic containers with tight-fitting lids is essential.  Put woolens and furs in a cedar chest.

Do NOT use chemical controls.  Mothballs (naphthelene) are ineffective and moth crystals (paradicholorobenzene) are potentially carcinogenic.

Hope the above links and information help.  Simply discard any infested items.


Carpet beetle adults are not really a problem, and in fact help pollinate some kinds of wildflowers.  The larvae, on the other hand, are the insect equivalent of juvenile delinquents.

Carpet beetle larvae feed on all manner of dried animal products, including, but not limited to:  pet food, taxidermy mounts, cured meats, insect collections (like mine, ARG!!), wool blankets and garments, silks, furs, even the accumulated shed hair of pets and people.

All you have to do is find the infested item(s) and discard it (them).  To prevent future infestations, store all vulnerable foodstuffs in glass, metal, or durable plastic containers with tight-fitting lids.  Store woolens, furs, and silks in a container inside a cedar chest, as cedar has proven repellent qualities and is not carcinogenic, unlike moth crystals.

You can find many images of carpet beetles and their larvae online, including:



and also in my book, the "Kaufman Field Guide to Insects of North America."  You can find more information on their control at any .edu website that addresses carpet beetles or "stored product pests" in general.

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.
