About Flit’s Active Ingredient

Flit’s active ingredient, permethrin, comes from the synthetic pyrethroids, which emulate naturally occurring pyrethrins found in chrysanthemum flowers. Permethrin is capable of controlling pests such as mosquitoes, ticks and flies. Permethrin has been registered with the EPA since 1979 and has been one of the most widely-used mosquito adulticide controls in the United States due to its low costs, high rate of effectiveness and broad use labeling.

Applying Flit

Flit is a barrier product, meaning it is applied to the vegetation and foliage where adult mosquitoes harbor/rest during daytime hours.  Barrier products are typically applied during the day, through a backpack blower that converts the liquid product into large droplets that land on targeted treatment sites like landscaped plants, foliage and tree lines. The treatment is designed to last on those surfaces for several days, controlling adult mosquitoes that land on the treated surface.

Flit can be applied by a manual pump garden sprayer, Ortho hose sprayer (available at hardware as well as home and garden stores), a power backpack or a high-pressure applicator.  This product is formulated for the control of annoyance flies and mosquitoes, mosquitoes and flies of public health or disease vector importance in areas such as but not limited to residential areas, industrial areas, urban areas, parks, campsites, woodlands, athletic fields, golf courses, playgrounds, recreational and overgrown waste areas, roadsides, and other areas.
