Biology

Anobiid Powderpost Beetles, as other beetles, feed on hard and soft woods in their larval stage. Anobiid larvae will bore tunnels and live inside the wood, which is usually older than 10 years. Anobiid Powderpost Beetles will create hole that measure 1/16 to 1/8 inch in diameter, and usually can be found in structural timbers. The greatest potential for damage is in the early stage of infestation, while the larvae are actively feeding.

Female Anobiid Powderpost Beetles typically lay about 50 eggs, and the lifecycle ranges from 2 to 3 years, with the majority of that time spent as larvae. Adult Anobiids are dark brown in color and measure 1/8 to 1/4 inch long, and range in shape from streamlined to oval.

Factoid

Unlike Lyctids, Anobiids reduce wood to pellets instead of a fine powder. (Factoid Source: J. DeAngelis, Extension Entomologist, Oregon State University)
