When Louisiana homeowners think of wood-destroying insects, termites are usually the first pest that comes to mind. However, powder post beetles can also cause significant damage to structural wood, flooring, furniture and other wooden materials.
As their name suggests, powder post beetles can reduce parts of infested wood to a fine, powder-like material. Adult beetles lay their eggs inside the pores or cracks of unfinished wood. After the eggs hatch, the larvae feed and tunnel through the wood as they develop.
Depending on the species and surrounding conditions, the powder post beetle life cycle may take several years to complete. Because most of the damage happens inside the wood, an infestation can remain unnoticed until adult beetles emerge.
Signs of a Powder Post Beetle Infestation
Adult powder post beetles tunnel out of infested wood and leave small, round exit holes behind. You may also notice fine powder, sometimes called frass, collecting near the holes or beneath damaged wood.
Common warning signs include:
- Small, round holes in wooden surfaces
- Fine, powder-like material near the holes
- Weakened, crumbling or damaged wood
- Adult beetles near windows or light sources
- New holes appearing in previously undamaged areas
Old exit holes do not always indicate that an infestation is still active. A professional inspection can help determine whether the damage is recent and whether treatment is needed.
The LSU AgCenter provides additional information about powder post beetles, including their appearance, behavior and the types of wood they commonly infest.

Ignoring an active powder post beetle infestation may allow the larvae to continue damaging the wood for years. If you notice small exit holes, fine powder or weakened wood around your home, contact The Bug Man for a professional evaluation.
Owners of raised homes and pier-style structures should pay particular attention to exposed wood beneath the building. Request a free estimate or call 225-923-2847 to learn more about wood-boring beetle control.
