Hi-Yield 38-Plus Insect Control - 38% Permethrin is labeled to kill fleas. You should apply 0.4 to 0.8 oz. per 1,000 square feet outdoors. We would also recommend using an Insect Growth Regulator such as Archer with Hi-Yield 38-Plus. Please see our Flea Pest Guide for more information about flea control.
