OFF!® Bug Control Backyard Pretreat is a concentrate that, when attached to a hose and sprayed around a backyard, will protect an area up to 16,000 square feet from 110+ insects for up to eight weeks. It works to protect trees, shrubs, ornamentals, structures and a number of vegetables from insect damage. The hose end is easy to use: just connect to a garden hose and spray. The trigger feature delivers a straight stream for taller trees and a fan pattern for low-lying plants and gardens.
