Cylinder Refill Unit

Designed to work exclusively with the Skeeter Defeater Dispenser, the Cylinder Refill Unit (CRU) contains pyrethrin, a botanical insecticide that kills mosquitoes on contact. Each CRU contains enough insecticide for 66 sprays, which will last 33 days when your dispenser is set to spray automatically at dusk and dawn, as recommended. The CRU is the only insecticide on the market designed to work with the Skeeter Defeater Dispenser.
