How can rats be eliminated from under the floor of a private house? - in detail
Inspect the crawl space thoroughly. Identify gnaw marks, droppings, and pathways leading to the sub‑floor area. Use a flashlight and a mirror to examine hidden corners, pipe penetrations, and vent openings.
Seal all potential entry points. Apply steel wool or copper mesh to gaps around utility lines, then cover with expanding polyurethane foam or cement. Install metal flashing around foundation cracks and repair damaged siding. Ensure vents are fitted with fine mesh screens.
Implement a trapping program. Place snap traps or electronic kill traps along established runways, positioning them perpendicular to walls with the trigger end facing the wall. Bait traps with peanut butter, dried fruit, or canned fish. Check traps daily, dispose of captured rodents promptly, and reset traps as needed.
Deploy rodenticides cautiously. Use anticoagulant baits in tamper‑resistant stations placed out of reach of children and pets. Follow label instructions regarding dosage and placement. Rotate active ingredients to prevent resistance development.
Maintain a clean environment. Remove food sources by storing pantry items in sealed containers, cleaning crumbs from floors, and securing garbage in tight‑fitting lids. Reduce clutter in the crawl space to eliminate hiding places.
Consider professional pest‑control services for severe infestations. Certified technicians can conduct fumigation, apply advanced baiting systems, and provide long‑term monitoring solutions. Regular follow‑up inspections ensure the problem does not recur.
