Some ignorant *******s suggest killing the carpenter bees but then
they are the same folks who brought us DDT, MTBE, Tetraethyl Lead,
Thalidomide, Nerve Gas,etc.
These folks choose the most expediant method with no thought of
consequence.

For the price of a few holes in a wooden fence you get pollinators.
Somebody gets more fruit in their garden, some songbird gets an extra
berry, wildlife survives.

As for carpenter bees stinging,yes the female can sting but you have
to force it to do so. Don't carry them in your shirt pocket or put
them in your mouth or trap them in your armpits.

Enjoy the show.
