D-Force HPX will eliminate carpenter bees in their holes. D-Force HPX does not offer an instant knockdown and the bee will die within a few hours of contact. We recommend that you use a concentrated liquid insecticide such as Equil Lambda 9.7 on the exterior of your home to eliminate any other carpenter bees that may fly into the area in search of a place to drill a hole. By spraying the wood you would help prevent furture damage from carpenter bees. The male carpenter bees do not cause damage and they cannot sting but they will be eliminated if they land on any treated area.
