Carpenter Bees Management Guidelines--UC IPM



(Roy) in :

I kill em all usually with a badmitton racket.

must be a rather dented racket :-)

Boric
acid is good at drying out their tunnels so the larvae starves as it
does not get decent food once its stored supply is dehydrated. It also
does good on the adults. The females can sting, but males do not have
stingers. They don;t get a chance to prove what they are around me as
I kill em all.

and they aren't very aggressive. at first i felt a bit freaked around them,
but they just bob around as if i'm not around.

Plenty of good honey bees around that do not cause such
damage in structures.

i think the honeybee losses have left a void for pollinators such as
carpenter bees.


Use a ear syringe filled with boric acid and squirt the powder up in
their tunnels. As the female goes in to carry food etc she gets boric
acidon her and it eventually kills her by dehydrating her.

diatomaceous earth does same. use a squeezable bottle with extension tube
taped to opening.

Opinions expressed are those of my wifes,
(wife's? or how many wifes, wives?)

I had no input whatsoever.
