Seal entry points, set traps or bait stations, and keep food storage airtight to eliminate the infestation. If the problem persists, contact a licensed pest‑control professional.
In the house, field mice have appeared, what should I do? - in detail
Field mice entering a residence require a systematic response that eliminates current infestation and prevents recurrence.
First, confirm activity. Look for droppings (small, dark pellets), gnaw marks on wiring or food containers, and nests constructed from shredded paper or fabric. Identify entry points by inspecting foundations, walls, windows, doors, and utility openings; gaps as small as ¼ inch allow access.
Next, reduce attractants. Store food in airtight containers, clean crumbs and spills immediately, and keep garbage sealed. Remove standing water sources and declutter storage areas where nesting material may accumulate.
Implement exclusion measures. Seal cracks and holes with steel wool, copper mesh, or cement; install door sweeps; repair damaged screens. Ensure vent covers and utility penetrations are fitted with appropriate hardware cloth.
Deploy control devices. Options include:
- Snap traps positioned along walls, baited with peanut butter, seed, or dried fruit.
- Live-catch traps for humane removal, placed near known pathways; release captured rodents at least 2 miles from the property.
- Electronic traps delivering a rapid lethal shock; follow manufacturer safety guidelines.
- Bait stations containing anticoagulant rodenticides, used only where children and pets are absent and in compliance with local regulations.
Monitor traps daily, dispose of carcasses in sealed bags, and reset devices until no captures occur for several consecutive nights.
Finally, consider professional pest‑management services if infestation persists, structural damage is extensive, or chemical controls are required. Experts can perform thorough inspections, apply targeted treatments, and provide a maintenance plan.
Maintain the preventive routine: regular inspection of seals, prompt sanitation, and periodic trap checks to keep the environment inhospitable to field mice.
