How to combat a mouse infestation? - briefly
Seal all potential entry points, then place snap traps, live traps, or bait stations along walls and near suspected pathways. Maintain a clean environment by storing food in sealed containers, promptly cleaning spills, and regularly inspecting for signs of activity.
How to combat a mouse infestation? - in detail
A thorough approach to eliminating a mouse problem begins with assessment, prevention, eradication, and follow‑up.
First, identify entry points. Inspect the building’s exterior for gaps larger than ¼ inch in foundations, walls, doors, windows, and utility penetrations. Seal openings with steel wool, copper mesh, or concrete, and apply caulk to cracks. Install door sweeps and repair damaged screens.
Second, reduce attractants. Store food in airtight containers, clean crumbs and spills promptly, and keep garbage in sealed bins. Remove clutter that can serve as shelter, especially in basements, attics, and storage rooms.
Third, implement control measures. Choose one or more of the following methods:
- Snap traps: Position baited devices along walls, behind appliances, and near known activity. Check daily and dispose of captured rodents promptly.
- Electronic traps: Use devices that deliver a lethal shock; they provide quick results and reduce risk of secondary poisoning.
- Live traps: Capture rodents for release far from the property, complying with local regulations.
- Bait stations: Place tamper‑resistant stations containing anticoagulant poison in concealed locations. Follow label instructions and keep away from children and pets.
When using poison, rotate active ingredients to prevent resistance and monitor for non‑target exposure.
Fourth, verify effectiveness. After a week, reassess activity signs such as droppings, gnaw marks, and audible noises. Continue trapping and monitoring until no evidence remains for at least three consecutive weeks.
Finally, maintain long‑term protection. Conduct periodic inspections of the building envelope, keep food storage secure, and keep the surrounding landscape trimmed to eliminate hiding places. Document any new findings and address them immediately to prevent recurrence.
