Locate and block all potential entry routes, then set snap or electronic traps in areas where activity is observed. After capture, dispose of the rodent, disinfect any contaminated surfaces, and contact a professional exterminator if the infestation continues.
What to do if a rat appears at home? - in detail
If a rodent is discovered inside the dwelling, act promptly to limit health risks and prevent recurrence.
First, protect occupants. Keep children and pets away from the area. Wear disposable gloves when handling any evidence or setting devices.
Next, identify the extent of activity. Look for droppings, gnaw marks, shredded material, and grease stains along walls, cabinets, and appliances. Record locations to guide treatment.
Then, eliminate food sources. Store all food in sealed containers, clean countertops, sweep crumbs, and empty pet feeders after each use. Remove standing water and fix leaks that could attract the animal.
After sanitation, block entry points. Inspect the exterior and interior for gaps larger than ¼ inch, especially around pipes, vents, doors, and windows. Seal openings with steel wool, caulk, or metal flashing; use expanding foam only where rodents cannot chew through.
Deploy control measures. Choose one or more of the following, based on the situation and local regulations:
- Snap traps placed perpendicular to walls, baited with peanut butter or dried fruit, positioned near signs of activity.
- Live‑capture traps, inspected daily, with humane release at least 5 m from the residence.
- Electronic traps that deliver a lethal shock, requiring minimal handling.
If traps are insufficient, contact a licensed pest‑management professional. Request an integrated pest‑management plan that includes inspection, targeted baiting, and ongoing monitoring.
Finally, maintain a preventive routine. Conduct monthly checks for new entry points, keep waste containers covered, and keep vegetation trimmed away from the building foundation. Regularly clean storage areas and dispose of garbage promptly. Consistent vigilance reduces the likelihood of future infestations.
