Annihilator™ Polyzone® uses technology that binds active ingredient to surface, slowly releases over time and provides residual control that lasts for up to 90 days. It’s exclusive formulation protects the active ingredient from weather, wash-off and mechanical abrasion. Longer residual control may result in cost savings by reducing labor and number of applications required. Just mix with water and apply with hand-pressurized or power-operated sprayers. Contains deltamethrin 4.75%
