Gasoline petrol kerosene are some of the toxic chemicals that carpenter bees abhor and hence can be used for getting rid of them.
Do carpenter bees eat treated wood. Carpenter bees do not really eat wood but they chew out holes and makes nests inside where eggs hatch and create more carpenter bees increasing the destruction. While the pests do not eat wood they excavate tunnels to use as nests. No it s not for their food. Avoid wood treatment solutions though as the bees don t eat wood and hence might not be affected by it.
They can dig neatly through wood. They re only drilling through it. But by taking these steps and staying alert to new activity you can keep damage to a minimum. There s no way to completely prevent or eliminate carpenter bees.
Pressure treated lumber is generally well protected against decay fungi and most insects that eat wood. Since carpenter bees don t actually eat wood treating it doesn t do much good. Wood boring carpenter bees resemble bumble bees but these large bees excavate tunnels in wood to make a nest whereas bumble bees nest in soil. This nest building can damage wood trim doors and so forth.
Carpenter bees as the name have the behavior to drill into the wood. Unfinished or weathered wood attracts the robust black and yellow carpenter bee. That being said in my experience it would seem that in general most carpenter bees prefer untreated wood over pressure treated lumber. These are usually in the eaves of homes as well as in decks siding fascia boards or porches.
I ve seen plenty of nests located in pressure treated lumber so whatever is being injected does not seem to slow them down or kill them. They re also pollinators which make them very important for helping crops and gardens grow. Since their nest tunnels are limited in size they rarely do serious structural damage. Carpenter bees are so named because they drill into wood to lay their eggs and build their nests.
Though they burrow into wood carpenter bees don t eat wood like termites do. If you are having a problem with carpenter bees it is best to get rid of them as soon as possible.

While wood boring carpenter bee damage is usually minor it should still be repaired as soon as possible to prevent water.
But remember carpenter bees aren t eating the wood. Third if the wood is subject to a lot of moisture mold and fungus it will increase the odds of it becoming a nest site. However because such excavation requires a lot of energy on her part a female carpenter bee will often prefer to refurbish an old tunnel to digging a new one. Carpenter bees don t eat wood they only drill holes through them to build their nests and lay eggs.
