Termidor SC will kill carpenter bees but it can only be applied 1ft up and 1ft out from the foundation, around windows, doors, and under the eaves of the rooflines or patios coverings. This cannot be applied using a pressure washer to reach high, we would suggest the Chapin Slide Pump Sprayer that shoots 25-30 ft vertically. Please see our Carpenter Bee Kits for the best products to use to treat for this pest.
