Designed to be used with Tomcat Mouse Killer (1 oz) Baits. I got tired of buying the expensive bait stations for such a simple application. With this you can just buy the bait and print as many holders as you want. (I printed several for all corners of the attic.) It has an included mounting hole to prevent accidental spills. Also keeps the little critters from stealing them.

Warnings: It is recommended to always wear gloves when handling the bait. Also, this is designed to use very little plastic; it does not offer any additional protection. Only use these in areas where children and animals cannot gain access.

UPDATE After a week, I found 2 dead mice. I think the results speak for itself.
