How do you use boric acid to control carpenter bee infestation?

Answer 1

Go to: http://www.bugclinic.com/carpenter_bee.htm and to: http://www.alsnetbiz.com/homeimprovement/boric_acid.html It looks like the best method is to "dust" the entrance hole so the female crawls through the dust and carries it back to the eggs or larva. Gary Totten

Answer 2

To control carpenter bee infestation using boric acid, you can mix it with water to create a spray solution and apply it directly to wood surfaces where bees have been active. Boric acid is toxic to insects but safe for humans and pets when used properly. It can help deter carpenter bees from nesting in the wood.
