When an unwanted mouse in the house has got to go, the Tomcat® Mouse Killer Refillable Bait Station is the way to go. Kills house mice indoors and outdoors. This reusable bait station is designed so mice can enter from either side and feed. Plus, the see-thru lid lets you quickly see if mice have consumed the bait. The child and dog-resistant bait station let you easily fill and refill. Wearing gloves, place one block of bait in the bait station. Use in attics, garages, and basements. Place vertically or horizontally in corners, behind appliances, between floors and walls, or other places house mice hide.
