"The efficacy of pesticides for control of camphor shoot borer has not been tested. Systemic neonicotinoids and pyrethroids (e.g., imidacloprid and bifenthrin) have been effective in reducing the attacks of some ambrosia beetle species but not others, so they may or may not be effective against camphor shoot borer. A surface spray of permethrin can reduce the number of attacks by other problem ambrosia beetles, so may also be effective for camphor shoot borer. If a surface insecticide is used, it should be applied to the plant above 0.5 meters when beetle activity peaks (April and May in the southern U.S. and probably May and early June in Pennsylvania)."
