Mice look cute, but they’re an amazing vermin. If you see one inside the house, others will follow. They enter the spaces between the walls, where you can hear them passing by day and night. And they reproduce incredibly quickly. Eliminate common mice now with the reusable MOUSE OUT Mouse Bait Point with Warfarin. Each bait station includes 16 bait blocks. The bait blocks contain warfarin, an anticoagulant chemical that reduces the blood’s ability to clot. After several ingestions, the common mice die from a fatal hemorrhage. Fair winds! The bait station can be locked to be childproof.
