How can I evict a mouse that is under the floor in an apartment? - in detail
Identify the exact location of the rodent. Listen for scratching or scurrying, tap the floor lightly to detect hollow spots, and use a flashlight to look for droppings or gnaw marks. Once the area is pinpointed, create a clear path for the animal to exit by removing any obstacles that could block its movement.
Seal all possible entry points. Inspect the perimeter of the apartment, especially where the floor meets walls, baseboards, and utility openings. Apply steel‑wool, copper mesh, or silicone caulk to gaps larger than a quarter‑inch. Repair cracked tiles, loose floorboards, and damaged vent covers.
Deploy traps directly over the identified zone. Choose snap traps or electronic traps for immediate kill; place them perpendicular to the wall with the trigger end facing the wall. Use fresh peanut butter, chocolate, or dried fruit as bait. Set multiple traps at 12‑inch intervals to increase capture probability.
If capture is not immediate, consider live‑catch traps. Bait them similarly and check them at least twice daily. Relocate captured mice at least two miles away from the residence, releasing them in suitable habitat.
Apply non‑chemical repellents to discourage re‑entry. Place cotton balls soaked in peppermint oil, eucalyptus oil, or ammonia near entry points and along the floor’s edge. Replace monthly or after cleaning.
When traps and repellents fail, contact a licensed pest‑control professional. They can perform thorough inspections, apply rodent‑grade baits, and install tamper‑proof sealing systems that meet local housing regulations.
After removal, maintain a mouse‑free environment. Store food in airtight containers, keep countertops clean, and dispose of garbage regularly. Conduct periodic inspections of the floor and walls to detect new activity early. Continuous vigilance prevents future infestations.
