STORMTROOPER is an EPA registered water based aerosol Fire Ant Killer. Contains 0.15 % Tetramethrin and 0.375% Permethrin to provide quick killing action and residual control for up to 4 weeks. Stormtrooper produces a dense expanding foam dispensed through a mound injector which penetrates deep into the mound, instantly killing all contacted insects. This dense long lasting foam increases contact time and blocks escape routes. One can treats 8 to 10 small mounds, 6 to 8 medium mounds and 4 to 6 large mounds. One mound injector included with each case.
