This is the cordless mister that can be rolled anywhere in a yard to repel mosquitoes in a 2,000' sq. area. It uses EPA-registered permethrin--a synthetic form of naturally occurring pyrethrin derived from chrysanthemum--to kill up to 90% of mosquitoes, flies, gnats, no-see-ums, ticks, and other biting insects for up to six hours with only a three-minute misting. Permethrin biodegrades quickly so it is safe and gentle on the environment. The mister has a rustproof, two-gallon polypropylene tank that accepts a bottle of permethrin (sold below) mixed with water from a garden hose; three nozzles generate a fine mist. The mister can also be operated from up to 100' away via remote control. Smooth rolling wheels and handle provide easy setup. Its rechargeable battery provides up to 15 mistings from a four-hour charge using the included AC adapter. 22 1/2" H x 15" W x 12" D. (13 lbs.)
