Mice often make nests inside walls, above ceilings and in crawlspaces. Homeowners who have mice in wall voids have likely heard scrabbling or chewing noises after dark. Since mice venture out of the walls to forage for food, sanitising your home and removing food sources are the first steps in mouse control. Use at least two methods of removing or killing mice for best results, such as traps and poison. You may use either rodenticide or tracking powder. The tracking powder will coat the mouse's fur and will then kill it after it grooms itself.

Clean your house from top to bottom, especially your kitchen and pantry. Remove all crumbs. Check all food items that are not refrigerated. Discard any that have holes or other evidence of mouse damage. Store all food items, except canned goods and similar items, in sealed, hard plastic bins.
Inspect your walls and doorways to locate possible points of entry. Make a note of any crevices that mice could use to get in and out of your walls. Mice can go through openings about the diameter of a pencil, according to the University of Illinois Extension Champaign County.
Wait until after dark or wake up early in the morning. Walk around your house listening to the walls and ceiling. Mice are active at night. Make a note of any areas where you hear them moving around or gnawing. These are likely the nest locations.
Set traps along the wall near the nests. Bait them with raisins or peanut butter. Place them no farther than 10 feet away from the nest or the wall opening nearest the nest. Mice do not venture far to forage, usually no more than 10 to 25 feet, according to the University of Kentucky.
Check your traps every morning. Bait them again if necessary. Wearing plastic gloves, dispose of any captured mice and wash your hands well afterward.
Insert either a rodenticide or a tracking powder into the crevices in the walls you identified. Some injectable baits come in the form of a tube. Squeeze the poison into the wall. Force the tracking powder into the crevice with a small spatula. Discard the spatula after use. Treat all crevices near the nests in this manner.
