Powderpost wood-borer beetles are tiny insects that burrow into wood. They can seriously damage furniture, flooring, and even the structure of homes or businesses.
When you see small holes in hardwood floors, door frames, or antique furniture, it may be the first sign of activity. Unlike termites, which eat wood continuously, powderpost beetles spend much of their life cycle hidden inside, quietly chewing through wood products. The infestation may already be advanced by the time the damage becomes visible. That is why contacting a pest control professional is the most reliable way to stop the problem and prevent further destruction.
Color: Reddish-brown to dark brown
Legs: 6
Shape: Narrow, cylindrical body
Size: About 1/8 to 1/4 inch long
Antennae: True
Powderpost beetles are a group of seventy different species of wood-boring beetles. Unlike most similar wood-boring insects, they have distinctly visible heads and antennae with two-jointed clubs. Their primary food source is deciduous trees, which they bore into and reduce to powdery dust over time. Powderpost beetle larvae live inside wood and feed on the natural starches and sugars as they grow.
What makes them especially concerning is their life cycle. Females lay eggs inside cracks or pores of unfinished or unsealed wood. Once the eggs hatch, the larvae burrow deep into the wood and feed for months or even years. It is during this stage that the most damage occurs.
Because they prefer wood with high starch content, powderpost beetles often target hardwoods such as oak, ash, and walnut. This makes them a threat to furniture, hardwood flooring, trim, paneling, and even structural timbers. The fine, talcum-like frass, a combination of wood particles and droppings, is one of the main indicators of activity. Over time, untreated infestations can weaken wood to the point where it crumbles to the touch.
Powderpost beetles cause a lot of damage because they spend most of their lives hidden inside wood. These are the reasons they are hard to spot early:
Powderpost beetles are hard to spot because they spend most of their lives inside wood. Learning the warning signs can help you catch the problem sooner and prevent costly damage. Look out for the following:
One of the clearest signs is a fine, flour-like powder called frass found around or under wooden items. This powder is waste left by larvae as they tunnel through wood. Fresh frass is light in color, while older frass turns darker over time.
Adult beetles chew their way out of wood, leaving tiny round holes about 1/32 to 1/16 of an inch wide. If you find these holes in common problem areas such as hardwood floors, furniture, or beams, it is a strong sign of beetle activity.
Wood with a heavy infestation may feel soft or hollow when tapped. In serious cases, the surface can crumble easily because larvae have eaten away the inside.
If you notice any of these signs, consider getting a professional inspection. Our technicians can identify the beetle species and suggest the best way to protect your property from destructive, wood-boring insects.
Powderpost beetles are attracted to wood with a lot of moisture and starch, especially unsealed or unfinished surfaces, where females can easily lay eggs. They often get in through firewood stored indoors, untreated lumber, or antique furniture that hasn’t been checked.
To reduce your risk:
DIY treatments might help with surface beetle activity, but they usually don’t reach larvae deep inside the wood. For long-term protection, professional powderpost beetle control from Gregory Pest Solutions is your best bet.

Yes, adult beetles can fly, which is how they move from one piece of wood to another. Their short adult lifespan is focused on reproduction.
No, powderpost beetles do not bite humans or pets. The damage they cause is limited to wood products.
Treatment depends on the extent of the infestation. Furniture may be treated with surface applications or heat treatments, while infested flooring can require localized treatment, board replacement, or fumigation in more severe cases. A professional inspection is the best way to determine the right approach and ensure larvae hidden inside the wood are fully addressed.
Termites eat wood continuously and live in colonies, causing widespread destruction. Powderpost beetles, on the other hand, cause damage individually as larvae tunneling inside the wood, leaving behind exit holes and powdery frass.
