Discover our basic series model designed to spray insecticide every 7.5 minutes. We also carry a fully programmable model, which offers variable adjustment (spraying at intervals of 1 to 60 minutes). Finally, we also sell a semi-programmable model with three settings: spraying every 3.5, every 7.5 or every 15 minutes. All of our dispensers are easy to use and can be mounted on a wall or placed on a shelf.
