How to Get Rid of Mice Without Poison or Traps

By The Pest Repeller LLC Team · April 8, 2026 · 7 min read

Mice in the kitchen, attic, or garage are stressful. Most homeowners reach for snap traps or rodenticide bait first — but if you have small children, a curious dog, or just don't want a dead mouse to deal with, those options are non-starters.

Here's a layered, low-effort, humane approach that has worked for thousands of our customers.

Step 1: Cut off their food

• Move all dry pantry goods (rice, pasta, cereal, flour) into glass or hard plastic containers. Mice can chew through cardboard and most plastic bags within hours.
• Sweep crumbs from under the toaster, stove, and coffee maker every night. A daily vacuum under the kitchen baseboards goes a long way.
• Keep pet food sealed when not actively in use. Don't leave a kibble bowl out overnight.
• Take trash out daily; double-bag any food scraps.

Step 2: Cut off their entry

• Walk the perimeter of your home and look for any gap larger than a pencil — that's the size mice can squeeze through.
• Stuff steel wool into holes, then seal with caulk. Mice can chew foam and wood; they cannot chew steel wool.
• Check around utility line entry points (gas, water, electric), where vents enter the wall, and along the foundation sill plate.
• Don't forget the garage — it's the #1 indoor mouse origin point in most US homes.

Step 3: Make the space inhospitable

This is where ultrasonic pest repellers shine. A plug-in unit makes the space neurologically uncomfortable for mice without harming pets, kids, or appliances. They simply don't want to be there. Place one in:

• The kitchen (most common entry point)
• The garage (most common nesting spot)
• The basement or crawl space
• The attic (if accessible to outlets)
• Any room where you've heard scratching in walls

You'll typically see fewer signs of activity within 7–10 days, and most populations have permanently relocated within 3–4 weeks.

Step 4: Watch and verify

Look for fresh droppings (small black grains, smaller than a sesame seed) and chew marks. If you find them in week 3 or 4, place an additional repeller closer to the activity. If activity continues past 6 weeks, you may have a structural issue (a tear in your roof flashing, a broken vent screen) that's letting in a fresh mouse population — call a roofer or handyman, not an exterminator.

What you'll save

An average exterminator visit for a mouse problem runs $250–600. Repeat visits often follow. A 6-pack of ultrasonic repellers is $29.99 and provides ongoing prevention without monthly fees. The math is straightforward.
