If not, buy regular traps and hot-glue pieces of boxboard onto the triggers to make them as large as the ends of the traps. Bait the traps with peanut butter, chocolate, malt-flavoured kitty hair ball remover or even a dead insect. Don't bother with cheese. In spite of all the cartoons showing cheese on mouse traps, it really isn't much good. Place the traps in pairs about 5 cm apart, perpendicular to and touching walls in places you have found mouse droppings.
Some mice jump when they first encounter a trap.
By putting them in pairs the second trap will catch the mouse as it lands. Good places for traps are in corners, behind refrigerators, behind stoves, under kitchen sinks, in crawl spaces under the cottage and sometimes in attic spaces. To successfully trap mice, you must be thorough in your search for their droppings and in your trap placements. Use lots of traps. Fifteen to thirty traps would not be too many.
