When using Spectracide Triazicide Once & Done Insect Killer Concentrate for bagworm control you should mix 0.75 fl oz (1½ Tbsp) in 1 gallon of water. For bagworm control, apply when bagworm larvae begin to hatch because once the bagworms have matured and have formed the "bag" most chemical control methods will no longer work. Please take a look at our article on Bagworm Control.
