CARPENTER BEES EATING MY HOUSE!

CARPENTER BEES EATING MY HOUSE!

I was outside this weekend doing some gardening around my deck when my fiancé said, “oh look at that bumble bee”, I say “that’s no bumble bee!” hoovering over my deck, “that’s a carpenter bee!”. I look up and sure enough my siding had the tell-tale sign of yellowish brown splatter trailing down from behind my fascia board. “This is their feces” I explain to my fiancé to which she plainly stated, “ewww, that is disgusting!”.

Carpenter bees get their common name from their habit of boring into wood to make galleries for the rearing of young. They differ from bumble bees in appearance by having a bare, shiny black abdomen compared to bumble bees, which have a hairy abdomen with some yellow markings. The male carpenter bee has a yellow face, whereas, the female’s is black.         

Females will nest in a wide range of woods, but prefer weathered and unpainted wood. The entry hole is 3/8 to ½ inch in diameter and initially about 6 inches long; in subsequent years, however, this may extend too more than 10 feet. Males tend to be territorial and often become aggressive when humans approach, sometimes hovering a short distance in front of the face or buzzing one’s head. Since males have no stinger, these actions are merely show.  However, the female does have a potent sting, which is rarely used.

Adults overwinter in abandoned galleries, emerging in the spring to mate. The mated female prepares a nest by excavating a new site or more frequently by cleaning out and expanding existing galleries. After the nest is ready, she places a mass of pollen mixed with nectar in the blind end of the galleries, lays an egg on it, and builds a partition of chewed wood pulp to form a brood cell. Six to eight cells per galleries. Developmental time (egg to adult) is 30 to 40 days, usually late summer. There is one generation per year.

Over time carpenter bees will do some extensive damage to your home, so it is a good idea to get treatment as soon as you notice you have a problem. Call Guardian and we will come evaluate the extent of your infestation and treat accordingly to eliminate the carpenter bee infestation at your home.
