Lyctid Powerpost Beetle

Identify Powerdpost Beetles by Their Frass (Lyctid)

Powderpost beetles larvae excrete fecal material called frass which is mostly digested "sawdust." Differences in frass can help you identify the specific beetle pest.

*Round exit holes, 1/32 to 1/16-inch (0.6 to 1.5mm) in diameter.
*Flour-like frass under infested wood or sifting from exit holes.
*Flour-like frass does not contain tiny pellets (like anobiid powerderpost beetles)
