PERM-X UL 4-4 is the first choice for broad-spectrum mosquito and fly control. This convenient ready-to-use, low-odor formulation is recommended for application as an Ultra Low Volume (ULV) Thermal or Non-thermal aerosol (Cold Fog) in residential, recreational, industrial, urban and other areas where flying and biting insect pests are found.


PBO works by blocking production of cytochrome P450, the enzyme within insects that breaks down and reduces the efficacy of the active ingredients in insecticides. By blocking the action of this enzyme, piperonyl butoxide improves the effectiveness of the insecticide, providing quick knockdown and kill, while allowing lower use rates.

Insects Controlled: Adult mosquitoes, flies, black flies, gnats, biting and non-biting midges, as well as other biting flies
