Powderpost beetle

Jeff Hahn, University of Minnesota Extension

Jeff Hahn, University of Minnesota Extension

Description: 1/4 inch long. (It is often challenging to recognize small-sized beetles from a picture. Because different insects may be treated differently, be sure the insect is correctly identified before attempting control.)

Where/When: Is associated with wood products. Also look for small, round holes and fine, powder-like sawdust. Can be found indoors anytime during the year.

Significance: Can significantly damage small-sized wood products. Larger sized items can be marred by exit holes.
