Perm-X formulations are convenient, low-odor adulticides recommended for application as an Ultra Low Volume (ULV) Thermal or Non-thermal aerosol (Cold Fog) in residential, recreational, industrial, urban and other labeled areas where mosquitoes are a problem. Like Pyronyl formula, Perm-X formulations differ in their ratios of permethrin to piperonyl butoxide (PBO) to give users a rotation of consistently effective mosquito control.

Seven Perm-X products sit lined up with the three larger jugs in the back and the four smaller jugs in the front.
