Lyctid powderpost beetles only attack hardwoods and prefer wood that is less than 5 years old. These beetles usually attack oak, hickory, walnut, maple, bamboo, and ash, and require a moisture level of 8-32 % in the wood for proper development. They will attack manufactured items along with lumber. Most of the time an infestation occurs in a home after wood or lumber that is already infested with eggs or larvae are introduced into the home during the building process.
While these beetles are not dangerous to people and aren’t known to carry or transmit any known disease, they are extremely dangerous to the structural integrity of a home. Because wood is generally infested over and over again the damage that the larvae cause can become quite extensive and costly to repair.
