I used to mix my own boat bottom paint many moons ago to deter underwater growth while the boat sat at the dock. I have a huge problem with the big Boarer Bees drilling 3/8" holes in my Pole Barn rafters. Is there a poison or deterrent I can mix with exterior latex and paint on these beams to stop this problem. The bees drill/eat/nest in pressure treated wood and I have heard the only way to stop it partially is by heavy painting. I am extending the Pole Barn and would like to spray the beams and rafters before install. Can you recommend anything I can add to my paint. I can spray with a full face respirator, no one can reach the beams after install, and there are no children around.
D-FENSE SC may be mixed with latex coatings and oilbased coatings such as stains, varnishes and sealers for use to kill crawling and flying insects when exposed to treated surfaces. Please see our Carpenter Bee Treatment article for more information about treating for this pest.
