This bait station is ready-to-use and comes pre-baited to avoid the need for touching the bait lure at all. With the Advanced Formula the bait is now more attractive to house mice. With a clear lid, the bait station makes it easy to monitor the bait lure in order to identify whether or not it needs to be replaced. The Tomcat Mouse Killer Bait Station Advanced Formula is tamper-resistant to keep children and dogs safe from the toxic bait lure. This bait station can be applied in the kitchen area and in cabinets, but should not be placed near food to avoid contamination.
