If powderpost beetles have not already invaded your home, we also have some simple prevention tips for you to use to keep these destructive pests from invading.

What Are Powderpost Beetles?

Powderpost beetles are ⅛ to ¼ inch long reddish-brown to black pests known for laying their eggs in the cracks of wood. These eggs eventually hatch into grub-like larvae. Once hatched, larvae will begin to consume the wood around them creating meandering tunnels. These tunnels are the main source of damage these pests cause to homes. As powderpost beetles lay more and more eggs, problems from these pests grow exponentially. In America, the damage done by powderpost beetles is only overshadowed by termites, the number one home-destroying pests around the world.

What Types Of Wood Do Powderpost Beetles Infest?

Unlike termites, powderpost beetles do not require softwood to satisfy their needs. Although they prefer wood affected by water damage, rot, or decay, powderpost beetles are capable of chewing through hardwood as well.

 Inside homes, powderpost beetles chew through and lay their eggs in flooring, walls, paneling, and even wooden furniture.

How To Tell Powderpost Beetles From Other Pests

The way powderpost beetles damage homes is much different than that of their competitors, termites, and carpenter ants. Where the entry holes for termites are tiny, powderpost beetle holes often look like a holes left by a nail. Don’t be deceived though. These holes are only what you can see on the surface. Much more damage is happening deep within the wood itself. As infestations become severe, damage to wood will become more visible and you will start to see galleyways running through it. These alleyways will look more jagged and broken than the galleys made by carpenter ants. Carpenter ants are digging to build a nest while powderpost beetles are eating the wood.
