The Q&A Archives: Black Beetle Invasion

Question: We have problems this year with a small black beetle with a hard shell and a smaller head that comes out at night and crawls on the outside of our home. Some of the beetles find ways into the house and each evening and morning several can be found on a ceiling or floor. The beetle is approximately 1/4 inch long and do not hop like the description of a flea beetle. They look similar to a spider at first glance and crawl rather slowly when indoors. I would like to eliminate them indoors and at least reduce the numbers outdoors with natural means if possible, if not I would like to know which pesticide would be most effective. We live in a country subdivision with a lot of maple and pine trees.

Answer: I wish I could identify the insect by your description, but there are dozens of beetles that match! The best approach is to take a sample to your local Cooperative Extension office and as them to identify it. You can find knowledgeable people at Michigan State University Cooperative Extension, 963 S. Raisinville Rd., Monroe 48161. Phone (734) 240-3170.
