Amdro Quick Kill Carpenter Bee, Ant and Termite Killer Ready To Use is labeled to treat for carpenter bees, and this spray will likely reach about 8-10 feet. If you need to treat higher than that, you may need to use a ladder or consider using a different product. Let us know if you need a recommendation on a different product.
