Entomology (Study of Bugs)/flying insects in house



We have a flying bug problem in our house that we hope you can help us identify.  This bug ranges from 1/16-3/16 inch in length, crawls around like a lady bug and also flies mainly in evening.  They appear in all areas of the home.  The body (with wings closed) is dome shaped with a black body and a zig-zag white,black and tan pattern on the wings.  Would like to know where these are coming from and how to get rid of them. Location is Jacksonville, FL

Thanks for your help,

The insect in your image is a "Varied Carpet Beetle," Anthrenus verbasci .  Here's my standard response to questions about them (I get this a LOT!):

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 or metal 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.

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.
