As I was inspecting the deck, I came across a "stain" on one of the railings. Upon closer inspection, I realized it was carpenter bee feces.
Within minutes, I found one of the carpenter bee galleries. Carpenter bees will bore into wood and then continue boring, causing a considerable amount of structural damage. They will lay eggs in these galleries, which can be over 10-28 inches long! Once a carpenter bee makes a gallery, they will continue to use the same gallery year after year.
As I was inspecting one of the galleries I overheard a loud buzzing noise coming from underneath the deck. When I inspected I found several additional carpenter bee galleries underneath in the joists.
For treatment, I applied a residual aerosol application directly into each individual gallery. This residual application absorbs through the carpenter bees skin and will eliminate them as well as any newly-hatched carpenter bees leaving the gallery. Now the homeowner can enjoy sitting on his deck without worrying about carpenter bees bothering him.
Recently, I went out on a service call in Englishtown, NJ for a new residential client that was having an issue with bees on his brand new deck. Once I arrived, I began my inspection and came across several bees boring into the deck. Upon closer inspection, I identified these bees are carpenter bees.
Carpenter bees are similar in appearance to bumble bees, but their abdomen doesn't have any hair and is shiny black in color. While they can be aggressive, they very rarely will sting — the females do have stingers, but seldom use it. Once the weather turns warmer, they emerge and begin looking for a place to build a gallery to lay eggs.
