How to Get Rid of Mice Without Using Poison

Eliminate mice safely by sealing entry points, using snap traps with peanut butter bait, and removing food sources that attract them in the first place.

1. Seal the Gaps First. Walk around your home's perimeter and inspect for gaps larger than a dime. Mice can squeeze through surprisingly small openings. Look for holes around pipes, vents, doors, and windows. Stuff steel wool into gaps, then cover with caulk or expanding foam. Pay special attention to where utilities enter your home and areas where different building materials meet.
2. Cut Off Their Supply. Store all food in airtight containers made of glass or thick plastic. This includes pet food, birdseed, and pantry items. Wipe down counters nightly, sweep up crumbs, and fix any leaky pipes that provide water sources. Empty garbage cans regularly and use tight-fitting lids. Clean up fallen fruit from outdoor trees and secure compost bins.
3. Deploy Traps Smart. Place snap traps along walls where you've seen droppings or heard scratching. Mice travel along baseboards, so position traps perpendicular to walls with the trigger end facing the wall. Use peanut butter as bait - it's more effective than cheese because mice can't easily remove it. Set multiple traps about 6 feet apart for better coverage.
4. Stay Vigilant Each Morning. Inspect traps every morning wearing gloves. Dispose of caught mice in sealed bags and reset traps immediately with fresh bait. Clean trap triggers with soap and water to remove scent trails. Move traps to new locations if you're not catching anything after three days - mice learn to avoid danger zones.
5. Reinforce With Scent. Soak cotton balls in peppermint oil and place them near suspected entry points. Mice dislike the strong scent and will often seek other areas. Replace these every few days as the scent fades. Alternatively, sprinkle cayenne pepper or place used cat litter near holes as additional deterrents.
6. Watch for Comeback. Keep watching for fresh droppings, gnaw marks, or scratching sounds even after you stop catching mice. New mice can move in quickly if conditions remain favorable. Continue sealing any new entry points you discover and maintain clean conditions to prevent re-infestation.
