Frequently Asked Questions

Q: How long do the beetles take to show?

The larvae can feed inside the wood for years before the adults emerge through the exit holes, which is why the powder and the holes often appear long after the wood was installed. The inspection reads the activity level, not just the holes.

Q: How much does powderpost beetle treatment cost in Pendleton?

A borate wood treatment runs $300 to $800 in Pendleton, with the inspection from $150 to $350. Severe infestations may need fumigation, which runs higher.

Q: Are the powderpost beetles active or old?

The inspection distinguishes an active infestation from old damage. Active beetles leave fresh powder and new exit holes, which is what the treatment targets.

Q: Where do the beetles come from?

They are often brought in with infested lumber and hardwood, then spread to the framing and the floors. Bare, unfinished wood is the most vulnerable.

Q: Do the beetles damage the structure?

In a heavy infestation, yes. The larvae tunnel through the wood over years, which weakens the flooring and the framing.

Q: Is fumigation always required?

No. Fumigation is reserved for severe, whole-structure infestations. Most jobs are handled with a borate treatment applied to the infested wood.
