What should you do if a mouse or rat appears? - in detail
When a rodent is sighted inside a building, immediate action reduces health risks and prevents infestation.
-
Isolate the area. Close doors, seal vents, and keep pets and children away until the situation is controlled.
-
Identify signs of activity. Look for droppings, gnaw marks, chew holes, and urine odor. Record locations to guide treatment.
-
Eliminate food sources. Store all food in airtight containers, clean crumbs and spills, and empty garbage daily. Remove pet food after each feeding.
-
Block entry points. Inspect walls, foundations, windows, and utility openings. Use steel wool, caulk, or metal mesh to seal gaps larger than ¼ inch. Repair damaged screens and weather stripping.
-
Set traps or bait stations. Choose snap traps, electronic traps, or enclosed bait stations based on safety requirements. Place devices along walls, behind appliances, and near identified activity zones. Follow manufacturer instructions for placement density and bait type.
-
Monitor and record. Check traps daily, noting captures and trap locations. Replace ineffective traps and adjust placement as needed.
-
Dispose of captured rodents. Wear disposable gloves, place the animal in a sealed bag, and discard in an outdoor trash container. Clean the trap with a disinfectant solution before reuse.
-
Sanitize the environment. Apply an EPA‑registered disinfectant to surfaces that may have been contaminated by droppings or urine. Allow proper contact time, then rinse if required.
-
Evaluate the need for professional pest control. If captures are low but signs persist, or if the infestation appears extensive, contact a licensed exterminator for inspection and treatment.
-
Implement preventive maintenance. Schedule regular inspections of the building envelope, maintain landscaping away from the structure, and keep storage areas organized to discourage future incursions.
Following these steps promptly limits disease transmission, prevents structural damage, and reduces the likelihood of a recurring rodent problem.
