Carpenter bees are so called because of their habit of excavating tunnels inside wood with their strong jaws. The half-inch, round diameter entrance holes usually can be found on the underside of boards. A tell-tale bit of coarse sawdust often can be found on the surface under the hole. Wooden overhangs, decks, and additional exposed wood on residences are main targets. Treated and painted woods are less preferred; however, they’re not immune to attack.
While the destruction to wood from the drilling tasks of one bee is small, subsequent years’ broods expand the tunnel via branching tasks and might cause significant structural damage. Plus, they’ll usually defecate on walls or other items right under the opening, which causes stains.
Male carpenter bees are more frequently seen but aren’t able to sting.
They’ll hover in the area of the nest and dart after all other flying insects that venture into their territory. One common male behavior is to approach humans if they move rapidly or wave their hands in the air. Males might even fly a brief distance from humans, which causes unneeded panic.
However, the female is able to sting, yet rarely does. She has to be highly provoked (that is, handled) before she’ll sting.
Carpenter bees don’t consume wood. They’ll excavate tunnels for chambers and as a shelter where they can rear their young. Usually, they attack unpainted items like windowsills, doors, shingles, roof eaves, telephone poles, railings, and occasionally wood lawn furniture.
Carpenter bees begin their nest by drilling an almost perfectly round hole (around ½” in diameter) into the wood. Generally, the entrance hole is against the wood’s grain. When the tunnel is approximately 1” in-depth, the bee turns at a right angle to the first hole and tunnels with the wood’s grain. They like to attack wood that’s more than 2” thick.
Because of the complex treatment procedure and the quantity of time needed to perform the treatments, carpenter ants typically aren’t a pest most homeowners have a lot of success in eradicating. Most DIY remedies to rid your home of carpenter ants just don’t work, because the chemicals used aren’t effective. Keep in mind – if mixed improperly or misused, pesticides may be extremely harmful to pets and people.
Therefore, it is a process that is better left to the professionals. For more information on how OrgLawn can help eradicate your bee infestation problem.
