Inspect the area to locate entry points, set snap or live traps near the suspected location, seal all gaps, and contact a licensed pest‑control professional for eradication and prevention.

What should I do if a rat is under the floor? - in detail

If a rodent has taken up residence beneath your flooring, immediate action prevents damage, disease, and infestation spread.

First, confirm the presence. Listen for scratching or squeaking, look for droppings, gnaw marks, or fresh burrow entrances in baseboards or vents. Use a flashlight to inspect gaps around pipes, wires, and under appliances.

Secure the area. Wear disposable gloves and a mask to avoid contact with urine or feces. Seal off the room by closing doors and covering vents with fine mesh to limit escape routes.

Choose a control method.

  • Snap traps: place baited traps (peanut butter, dried fruit) along walls, near known activity points, and behind furniture. Position traps perpendicular to the wall, with the trigger end facing the wall.
  • Live‑capture traps: set similarly, check every few hours, and release captured animals at least 5 km from the property, following local regulations.
  • Electronic traps: insert bait, activate, and allow the device to deliver a lethal shock; dispose of the carcass according to municipal guidelines.
  • Glue boards: effective for monitoring but not recommended as a primary solution due to humane concerns.

If traps fail after several days, or if the infestation appears extensive, contact a licensed pest‑control professional. Experts can conduct a thorough inspection, use bait stations, and apply rodenticides safely.

After removal, eliminate entry points. Apply steel‑wool, copper mesh, or silicone sealant to seal cracks around pipes, vents, and foundation joints. Install door sweeps and weather‑stripping on exterior doors. Replace damaged insulation or flooring sections that show gnaw marks.

Finally, maintain a hostile environment for rodents. Store food in sealed containers, keep trash bins covered, and clean up spills promptly. Reduce clutter that offers hiding places, and schedule periodic inspections to catch early signs of activity.

Following these steps removes the current problem and reduces the likelihood of future incursions.
