Question 1

How do I know if those small holes in my floor are active or old damage?

Accepted Answer

If the edges of the holes are crisp and you find fresh, fine frass or sawdust nearby, that indicates recent activity. If the holes are weathered, discolored, or have spider webs, they’re more likely old. Another trick is to mark a hole area and check in a few weeks for new frass or new holes. For definitive answers, remove a small section and inspect the interior for larvae or live insects.

Question 2

Can I treat wood-boring insects myself?

Accepted Answer

You can address small, localized problems yourself if you’re comfortable following label directions and safety precautions. For example, plugging a carpenter bee hole after a labeled gallery treatment can be DIY. But for termites, widespread carpenter ant nests, or beetles inside structural members, professional treatments are often necessary.

Question 3

Does painting wood prevent carpenter bees and beetles?

Accepted Answer

Painting or sealing wood makes it much less attractive to carpenter bees and many powderpost beetles. Most of these pests prefer unfinished wood. So yes — proper finishing and maintenance are good prevention.

Question 4

Is fumigation necessary for powderpost beetles?

Accepted Answer

For deeply embedded infestations in built-in wood, whole-structure fumigation or heat treatment may be the most reliable option. For isolated pieces of furniture, targeted freezing, heat treatment, or local fumigation can work.

Question 5

Will removing trees solve a bark beetle problem?

Accepted Answer

Removing dead and dying trees is important to reduce local beetle pressure, but it must be done promptly and properly; otherwise, cut wood can still host emerging adults. Consult an arborist to decide which trees to remove and how to dispose of infested wood.
