How to permanently get rid of mice in your house?

To permanently get rid of mice in your house you need to use a complete integrated approach that removes them now and prevents them from coming back, because trapping alone without exclusion will lead to reinfestation. Start with a thorough inspection inside and outside to find all entry points, droppings, and nesting areas. Mice can squeeze through a hole the size of a dime, so check around pipes, vents, doors, windows, foundation cracks, and where utility lines enter. Seal every hole with steel wool combined with caulk, metal hardware cloth, or cement, as mice cannot chew through steel wool easily. Next, eliminate food and water by storing all human food, pet food, and bird seed in airtight glass or metal containers, cleaning crumbs and grease daily, fixing leaky pipes, and taking out trash nightly. Remove clutter like cardboard boxes, fabric piles, and old newspapers that provide nesting material. Set multiple snap traps or electronic traps baited with peanut butter perpendicular to walls where activity is seen, checking daily for at least two weeks. After no signs for five to seven days, continue monitoring. For long-term prevention, keep vegetation trimmed away from the house, store firewood away from walls, maintain door sweeps, and consider professional pest proofing for attic and crawl spaces.
