The Tomcat® Rat & Mouse Killer Child & Dog Resistant Refillable Station effectively kills up to 3 rats with one bait block while providing Tomcat's highest level of station security. Effectively kills rats and mice. Resistant to tampering by children and dogs, the reusable station gives mice easy access to bait and keeps fingers and dog paws out. The bait station is also weather- resistant, making it the ideal station for indoor and outdoor use. Also includes a see-through window for easy monitoring of bait, so you always know when you need to re-fill your station. Bait stations are easy to use, allowing placement in small places like entry and garage doors, below windows, near utilities and any other areas where rats and mice tend to hide. Based on no- choice laboratory testing.
