Where to Find Them on Your Property?

Anobiids attack mostly softwoods and hardwoods, mostly on the sapwood. They attack structural Timbers, lumber and some manufactured structures. Females lay their eggs on wood, under cracks, surface splinters, or old exit holes. Sometimes they can be found on tree hardwood, like a Broadleaf tree. Wood older than 9 years is the wood that they usually attack.
