This is related to the Lead Cable Borer and Bamboo Borer, but is very different in appearance. It is a large beetle that attacks primarily softwoods, especially plywood products, but also has been found emerging from oak furniture, leaving a round exit hole about ¼ inch in diameter. It may attack plywood in storage, and then be built into homes or furniture, and generally does not re-infest the wood once it emerges as an adult. On several occasions it has been found in large numbers on hospital roofs or in chemical warehouses, possibly attracted by odors at those sites. The development from egg to adult may take a year or up to several years to complete. It is a common beetle in nature in the western states, and often comes to lights at buildings.
Ensuring the use of clean, non-infested wood products is important, as this beetle is almost always built in with infested wood. For heavy infestations or valuable furnishings, fumigation will ensure the kill of the larvae prior to adults emerging and causing visible damage.
