Powderpost Beetles
Powderpost beetles are a common type of beetle. They’re a group of small wood-boring insects that infest dry, unfinished wood.
Adults lay eggs in cracks and pores of the wood. When the larvae hatch, they tunnel through the wood while feeding, leaving behind small exit holes and fine powder. Powderpost beetles might be tiny, but they can cause big problems inside your home.
How Do You Know if You Have Powderpost Beetles?
These wood-boring insects feed on unfinished wood, flooring, furniture, and even structural beams. Over time, their activity can turn solid wood into a fine, flour-like powder. Signs of an infestation can be subtle at first, but here are the most common indicators:
- Tiny, round exit holes about the size of a pinhead
- Fine, flour-like powder (frass) beneath wooden surfaces
- Weak or crumbling wood that breaks apart easily
- Small clicking or ticking sounds from inside wood (caused by larvae feeding)
If you notice any of these, it’s a good idea to call in professional pest control services.
How Much Damage Can Powderpost Beetles Do?
Powderpost beetles are not harmful to people or animals directly. They don’t bite, sting, or spread disease. The real problem comes from the damage they do to wood. These beetles don’t just damage the surface. They can hollow out wood from the inside. Over time, this weakens furniture, flooring, and even structural beams. Severe infestations can make wood so fragile that it crumbles under pressure.
Homeowners often underestimate the extent of the damage since much of it happens inside the wood where you can’t see it.
How Powderpost Beetles Get Into Homes
Most powderpost beetle infestations actually start before you even notice them. These pests often find their way indoors by hiding in everyday items or through small openings around your property. Here are the most common ways they get inside:
Infested lumber or furniture
Powderpost beetles often hitch a ride inside new or used wood. Unfinished furniture, antiques, hardwood flooring, and even decorative wood pieces can carry hidden larvae. Because the damage usually begins deep inside the wood, you may not see any signs until the beetles start emerging months or even years later.
Firewood
Bringing firewood inside is another common way beetles enter a home. Logs stored outdoors can harbor beetle eggs or larvae, and when that wood is stacked inside, the insects are given a direct path indoors.
Structural wood
During construction or renovation, untreated or poorly treated lumber can already contain beetle eggs or larvae. Once that wood becomes part of your home, the problem is sealed inside and may spread as the beetles mature.
Cracks and gaps
Adult beetles can also make their way inside through tiny openings around doors, windows, attics, or crawl spaces. Once indoors, they search for unfinished wood to lay their eggs, starting the cycle all over again.
Once inside, powderpost beetles thrive in places where wood is dry and unfinished, such as attics, basements, garages, and crawl spaces. Over time, an unnoticed infestation can spread from one piece of wood to multiple areas throughout your home.
How Long Do Powderpost Beetles Live?
Adult powderpost beetles usually live only a few weeks, just long enough to reproduce and lay eggs. However, their larvae can stay hidden inside wood for one to five years while they feed and grow. This long life cycle is why infestations can continue unnoticed for so long and why professional treatment is necessary.
How Do You Get Rid of Powderpost Beetles?
DIY methods rarely solve the problem because store-bought sprays don’t reach the larvae tunneling deep inside the wood. Professional treatment is the only way to fully eliminate an infestation.

Tips for Preventing Powderpost Beetles from Coming Back
Once an infestation is treated, the next step is keeping powderpost beetles from returning. Since most problems start with infested wood, prevention comes down to protecting the wood in and around your home. Here are some helpful tips:
- Seal or finish exposed wood. Powderpost beetles prefer unfinished wood. Applying paint, varnish, or sealant makes it harder for them to lay eggs.
- Check furniture and lumber before bringing it inside. Inspect new or secondhand wooden items for tiny holes or powder before use.
- Store firewood outdoors. Keep firewood stacked away from your home and only bring in what you plan to burn right away.
- Reduce moisture. Beetles thrive in damp environments. Use dehumidifiers in basements or crawl spaces and fix leaks promptly.
- Schedule regular pest control maintenance. Professional monitoring can help catch any early signs of activity before damage becomes severe.
By taking these simple steps and partnering with Alta Pest Control for ongoing protection, you can keep your home safe from powderpost beetles in the future.
