Your warm toasty house looks very inviting to lots of critters who are shivering outside.
Mice are one of the more common problems that homeowners encounter.
Fortunately, they are normally easy to deal with. You should position the traps near the area you think the mice are entering your home. Poisons are very effective but should not be used when young children or pets are present in the home. You will have to experiment to find the type of bait your mice like. The bait is placed at the rear of the trap and when the mouse goes in after it, the door falls closed behind him.
