Once you find an entry point, close it properly.
Small openings can be filled with suitable materials such as steel wool, wire mesh, caulk, or other rodent-resistant repair materials depending on the location. (US EPA)
Don’t only concentrate on large holes. A tiny opening can be enough for a mouse to get inside.
🍞 Step 3: Remove Their Food
Mice will stay where food is easy to find.
Keep food in tightly sealed containers made from materials such as thick plastic, glass, or metal. Clean up crumbs and spills quickly, and don’t leave pet food sitting out overnight. (CDC)
Don’t forget about:
- Cereal
- Bread
- Rice
- Pet food
- Nuts
- Seeds
- Food scraps
- Open garbage
A clean kitchen makes your home much less attractive to rodents.
🪤 Step 4: Use Traps Where You See Activity
If mice are already inside, sealing the house should be combined with trapping.
The EPA lists snap traps as one option for controlling mice, while the CDC recommends spring-loaded traps as part of rodent control. (US EPA)
Place traps in areas where you’ve noticed droppings, gnaw marks, or other signs of mouse activity.
Keep traps completely inaccessible to children and pets.
⚠️ What About Mouse Poison?
Rodent poison can work, but it should be handled carefully.
If you choose a rodenticide, use a tamper-resistant bait station and follow every instruction on the product label. Keep it away from children and pets. (US EPA)
For many homes, exclusion and trapping are preferable first steps.
🌿 What About Peppermint Oil and Other Viral “Hacks”?
You’ve probably seen claims that peppermint oil, cinnamon, cloves, or other strong-smelling ingredients will make mice permanently leave your house.
These tricks are popular online, but they shouldn’t be considered a reliable replacement for sealing entry points and removing food sources.
If you want mice gone for good, focus on the reason they’re able to enter and stay in the house.
🧹 Keep the Area Unattractive to Mice
Don’t give rodents places to hide.
Reduce clutter, particularly piles of cardboard, paper, fabric, and other materials that can become nesting areas. Outside, keep garbage contained and reduce potential shelter around the building. (US EPA)
🏠 The Real Secret: Stop Them From Coming Back
Catching one mouse doesn’t necessarily solve the problem.
If there is still an opening in the wall or foundation, another mouse can eventually enter.
That’s why the most effective strategy is a combination of:
SEAL → CLEAN → TRAP → PREVENT
Seal entry points.
Remove food and water sources.
Trap existing mice.
Continue checking your home for new openings.
🐭 Final Thoughts
The “secret trick” isn’t necessarily one magic ingredient.
The real trick is making your home difficult to enter and unattractive to mice.
Seal even small gaps, store food securely, clean up crumbs, reduce hiding places, and use appropriate traps where mouse activity is present. These practical measures are recommended by the EPA and CDC for preventing and controlling rodents. (US EPA)
If you have a persistent infestation or signs of a large number of mice, professional pest control may be the safest and most effective option.
