I read your article on carpenter bees and it stated that Drione dust was about the only long term product to use. We have several nests around our home. One has even nested in the top of our biddy pen. My concern about this product is whether it will harm honey or bumblebee’s. We have honey bee’s to harvest their honey and we use the bumblebee’s to help pollinate our gardens. Any information you could give would be greatly appreciated.
If you read through our CARPENTER BEE CONTROL ARTICLE, you’ll learn the DRIONE DUST should only be applied directly to the nests you see. Once applied, the holes should be sealed with the CORKS we have listed. If done properly, there will be no Drione out in the open so that means there won’t be any risk or danger to your honey and bumble bees.
However, you won’t be able to spray the CYPERMETHRIN as this concentrate would pose a hazard to your bees. This is the material listed in the article for chasing away bees and is used to stop them from drilling into exposed wood. However, the INSECT REPELLENT we have in the article can be used. It’s not a pesticide and should be used as a spray on any wood you’d like to protect from further carpenter bee damage. And though the honey and bumble bees won’t like the treatment odor, they won’t be in any danger from it. They too will avoid where it’s been applied but will still produce honey and pollinate your flowers as before.
