Controlling Your Carpenter Bees

HUNTINGTON, W.Va. (WSAZ) -- Ever seen those giant bumble bees flying around your home only to disappear into a tiny hole in your patio, deck or porch?

Usually home owners start getting these types of problems in May, but with the warmer than usual temperatures, the carpenter bees have started a little early this year.

They are dubbed the carpenter bee quite nicely because of their woodworking ability of creating a perfect designed hole in your wood home structures that I mentioned. Actually what these bees are accomplishing in your wood structures is excavating a home where the female bee can lay her eggs. If you ever looked closely, she drills that perfect round hole on the underside of the wood, not on the side or even top of the wood structure. The hole travels straight up then takes a right angle. Its on this horizontal part of the hole that she lays her eggs.

Like I mentioned, they have started early so if you are going to reduce this problem, you need to start now. They won't reduce the strength of the structure but they can certainly deface the looks of a nice deck.

The best method of eliminating the problem without pesticides is to have the structure made out of pressure treated wood. Next, oil base paint works somewhat and of course bare untreated wood is their favorite to drill into. When you do treat with an insecticide, you don't have to treat the whole wood surface.

As I mentioned, they drill in the bottom part of the wood so that's where you need to direct the spray. Make sure and read and follow the pesticide label before using any pesticide.
