Sadly I have had to use these and boy are they effective!! I had a mouse infestation last year and wound up trapping 18 mice in less than a week with these traps!! Only downside is once you catch em you gotta kill em. There's no "catch and release" as the glue is SO strong it will rip the skin off the mice. If you aren't fond of the idea of having to put them out of their misery, find a different type of trap.
