General Facts

Why do I have wood-infesting beetles?

Wood-infesting beetles include ambrosia beetles, long-horned beetles, wharf borers, metallic wood borers, true powderpost beetles, false powderpost beetles, and deathwatch beetles.

They typically live in forest, burrowing into trees to eat, but can be brought into the home inadvertently in already-infested furniture or in firewood brought in to use or store.

Wood-infesting beetle larvae consume wood, so adult beetles lay their eggs in pores and cracks in the wood, or just on the surface, to give the larvae that emerge an immediate food source.

How worried should I be about wood-infesting beetles?

Once wood-infesting beetle eggs hatch, the larvae drill down and consume the surrounding timber, before exiting as adult beetles, leaving exit holes in the wood. Adult beetles also leave entry holes in the wood, as they bore down to lay eggs.

All this can create wood dust, damage wooden furniture, flooring, or framing – or if they have targeted a structural element of your home, make the building unsafe.

Unfortunately, sometimes it can take the larvae years to develop into adults, so you may not even be aware you have a problem – and even once you realize you have an issue, these beetles within the wood may then re-infest or seek new lumber around the home.

For smaller pieces of infested wood that can fit in an oven, exposing the beetles to temperatures of at least 50°C for at least 30 minutes may kill them. Or you can try placing the wood in subzero temperatures for a long period.

However, it can be challenging to thoroughly eradicate wood-infesting beetles, since it depends on properly identifying the insect, plus knowing the age, species, and moisture content of the infested wood.

To successfully eliminate your wood-infesting beetle problem for good and keep them from returning or re-infesting, you need a professional pest control service.

How can I prevent wood-infesting beetles invading?
