EZ KLEAN is your solution for an economical, easy to operate, and easy to clean rodent bait station for safe control of rats and mice in your home and yard. To control mice and rodents, add your choice of solid, pellet, or liquid rodent bait to the EZ KLEAN station and lock the lid in place with a simple twist of a key. For outdoor use, place EZ KLEAN rodent bait stations along the outside wall of your home every 30 to 50 feet. You can also place them behind shrubs, around detached garages and in and around storage sheds. For indoor use, place the bait stations in attics, under sinks, and just about any other place where rodents are likely to hide or nest. Rodents will smell and seek out the bait and enter the trap to obtain it. Baits must be purchased separately. Suggested for use with Contrac Blox rodent bait. Only 1 key is provided per order. You can purchase additional EZ-Klean Keys separately.
