When you think of structure-destroying pests, termites or carpenter ants immediately spring to mind. What about powderpost beetles? These small wood-boring insects may be less well-known, but they are capable of reducing wood to a fine flour-like substance. Is your home at risk? Are there effective pest control steps you can take to prevent or mitigate damage?
Most people find damage before they find the actual insects; that is, you likely won’t know the powderpost beetle has invaded your structure until it’s left behind some evidence. Larvae burrow into the wood, feeding as they develop. A year to five years later, they emerge as adults, leaving behind small “shotholes” and laying eggs. The eggs hatch, bore into the wood…it is a destructive cycle, but one that is slow. This gives owners time to consult with a reputable Brevard County pest control service and decide on a course of action.
Infestations are most common on:
- Hardwood surfaces (ash, walnut, hickory, oak), including floors
- Plywood
- Bamboo surfaces
- Wood paneling
- Molding
- Window and door frames
- Furniture
- New construction or newly-manufactured items
To prevent or mitigate damage:
- If you build a structure or item yourself, make sure you use wood that has been properly dried and stored.
- Treat wood with varnish, paint, wax, or sealer. Powderpost beetles lay their eggs on unfinished wood. Be sure to cover over the adults’ exit holes to prevent re-infestation.
- Install a moisture barrier and increase ventilation in crawl spaces if you have found damage. This creates an inhospitable environment for the beetles.
- If damage is minimal or confined to a specific area, replace the wood.
If structure damage is more widespread, call a termite and pest control service for other options, including application of insecticides or fumigation. Powderpost beetles can be damaging – but you can catch them in the act and take steps to eliminate them.
