Keep trash in containers with tight-fitting lids. Avoid vacuuming or sweeping mouse droppings, due to the dangers of hantavirus, a deadly virus spread to humans through contact with rodents and rodent urine and droppings. Place traps or poison pellets near holes and in places where you've seen mice. The trigger should be as near to the hole as possible. Use fruit, candy or peanut butter as bait if your trap requires bait.
Check traps daily.
Put on thick gloves and remove the carcass from the trap once a mouse has been caught. Wrap the carcass in newspaper or a plastic bag and place it in an outside garbage can. Mice are prolific breeders and can have as many as 13 litters per year. They can squeeze through a hole as small as a pencil eraser and are excellent climbers. Inc. How things get done.
