Dusting and plugging existing holes will kill newly emerging carpenter bees. We recommend applying the dust to the carpenter bee nests late in the evening to make sure you are contacting the existing female carpenter bees. This is when they're most likely to be inside the nest and when they're less active. This will reduce the chances of being stung. This application will also help to eliminate the immature stage of the developing carpenter bee and will reduce the future carpenter bee population.
NOTE: ***While carpenter bees are solitary bees and don't attack in groups, it's possible that you can be stung while performing a treatment. If you're not allergic but are worried about bee stings you may want to consider purchasing and wearing a bee suit***
Using a hand duster, apply the chosen dust to each carpenter bee hole. After 14 days, plug the hole using a Trebor plug, Super Plug or wood patch material to stop other insects from invading at a later time. Dust applications typically need to be applied to each hole only once per season.
