Our Shrub-Spraying Program The Shrub-Spraying Program is an all-inclusive program where we apply chemicals to exterminate pests in your shrubs and hedges. We use, both contact and systemic chemicals at the same time to cover all avenues. We can also treat your Camellias and Azaleas for Lace Bug, Petal Blight and Scale insects. Your lawn will never have looked this healthy before!
