These traps are not fit for purpose. I suspected I had a mouse in my garage. I set one trap initially. The bait was taken of the trap. I then continued over a couple of days to set traps with different bait. the bait was continually being removed from the traps. I had 8 of these traps set and still nothing, except the bait being removed. They all snapped shut when testing, I can confirm they were set correctly. I purchased another trap set it with the same bait and caught a mouse within hours. Reset the new trap and again within hours caught another mouse. I've used many traps but these simply do not work !!!
