Enjoy a bug-free outdoor living area and kitchen with Danver's perimeter insect control system. The system automatically sprays a fine mist of botanical insecticide through nozzles installed around the perimeter of the backyard or the kitchen, living and entertainment center. Two to three short mists per day, scheduled around dawn and dusk, will achieve control over mosquitoes and other biting insects. The insecticide used is derived from the chrysanthemum flower and is degraded by sunlight or rain. There is no residue, and insects do not develop resistance to the ingredients.
