Plastic sheeting, wood or rubber are unsuitable for plugging holes. Snap traps are the preferred control method in homes, garages and other structures where only a few mice are present. Bait traps with peanut butter, chocolate candy, dried fruit, nuts or gum drops. Despite cartoon information, cheese is not the best bait. Set traps close to walls and behind objects.
Mice tend to follow walls so set traps so the trigger is in their path.
Set numerous traps and set a trap no more than 10 feet apart where mice are active. Live traps for mice are also available. Be sure to release them far from any structure. Poisons are available. Some baits cause death only after the baits are fed upon for several days.
