Cluster Fly Killer

Exterminate Prevent Auto Spray is the perfect combatant against the ongoing presence of cluster flies. Prevent Auto is designed for use within an automatic air freshener dispenser that can be then set to spray at regular intervals, releasing the spray into the air. The spray then spreads and dissipates leaving a residual effect, making it effective against cluster flies and many other flying and crawling insects. It is particularly useful where regular treatment by humans is awkward and not practical, such as in lofts, attics, and garages.
