Outdoor sprayers and foggers disperse liquid fertilizers, weed killers, pesticides, cleaning solutions, sealants, and more onto lawns, gardens, and building grounds. Handheld and cart sprayers pump liquids from their carry-along or roll-along tank to their spray wand for dispensing. Backpack sprayers strap on and distribute the weight of their tank across the shoulders to keep both hands free and reduce fatigue during extended use. Walk-behind sprayers set their handle at a comfortable height to push them along while spraying. Tow-behind sprayers hitch to a lawn tractor, ATV, or UTV for pulling to spray large areas. Vehicle-mounted sprayers allow transport to remote locations and feature high-capacity tanks to cover more ground than other types of sprayers. Foggers aerosolize chemical treatments to spray a fine mist over a wide area.
