| Powderpost beetles | Powderpost beetles | Powderpost beetles, or lyctids, feed on starch in hardwoods, such as oak, cherry, or ash, and they will also feed in bamboo. These insects are usually brought into a home in hardwood flooring, trim, plywood, and wooden articles such as furniture and tool handles. The adult beetle is small, 1/8-3/8 inch long, and is red, brown, or black in color. These adult beetles mate and lay eggs on unfinished wood. The larvae develop and feed within the wood for 8 to 10 months, causing the damage. Powderpost beetle damage is recognized by the powdery frass (excrement) that is produced and falls out of the emergence holes. |
