5562 Grain beetle

Grain beetle

5562  My name is Craig and I’m located just North of San Francisco, near the coast. These are very small, on the order of 1mm. I found them in a recessed light fixture; they may have been there for . I’d like to make sure they are not wood boring beetles that might be eating my house.
This most likely is a foreign grain beetle, Ahasverus advena (Coleoptera: Silvanidae); basically a nuisance pest that does little if any actual damage. See http://tinyurl.com/opnfj5b for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.
