My husband is a beekeeper with hives of honey bees in our urban back yard. Our garden shed is about 20 feet from the hive stand and the carpenter bees have assaulted the eaves of the shed for several years with more vigor each year. I’ve recently added a cedar trellis (painted) and repainted the shed trim, but am uncertain about using any form of dust to treat the carpenter bees. Honey bees are in full action mode as honey flow began. But we have always taken care to keep dust (Sevin, etc) out of the property because honey bees often confuse it with pollen and it can wipe out a hive. What would you recommend in this situation?
