Malathion 57% is not labeled for carpenter bees as it is not for use on structures where they would infest. Please see our Carpenter Bee Kits for the best products to use to treat for this pest. See our Carpenter Bee Pest Guide and Carpenter Ant Pest Guide for more tips and information. We do offer a Complete Bee Suit and a Basic Safety Kit for protective gear.
