Alpine Dust is labeled for general bees. If this product is applied in areas where carpenter bees are, it will make the area unhabitable for them to live and dry them out, killing them as well. Be sure to only do a light coating of dust to ensure that they do not avoid it. Please take a look at our Carpenter Bee Guide for tips on how to treat and prevent carpenter bees in the future.
