Been stung by honey bees, always wondered if bumble bees and Carpenter bees stung.
Wasps and Hornets get the spray on sight.
I am pretty sure that with all bees (not wasps) you are stung by the workers. Mostly.
The reason being that worker bees do not breed - but they are female.
The stinger is actually what would have been, if they were a queen bee, the ovipositor tube!
Interesting, if true.
I have a log home. I also have carpenter bees. I also have a tennis racket.
Each spring I practice my tennis swing outside.
There are 77 dead carpenter bees littering my property now.
Should nab another 10 today.
Speaking of which...I used to use that spray to keep sparrows and pigeons from nesting in our roof tile grooves, but found out that spraying WD-40 works perfectly. Zero recidivism from the little winged pests.
