What should I do if there are many mice in the house? - briefly
Seal all possible entry points, then use snap traps, live traps, or bait stations to reduce the population; monitor regularly for activity. If the infestation persists, engage a licensed pest‑control professional for comprehensive treatment.
What should I do if there are many mice in the house? - in detail
A large mouse infestation requires a systematic approach that combines immediate reduction, exclusion, and long‑term prevention.
First, verify the extent of the problem. Look for droppings, gnaw marks, and active pathways along walls, behind appliances, and in stored food areas. Document hotspots to prioritize treatment.
Second, eliminate food sources. Store all dry goods in airtight containers, clean crumbs and spills promptly, and secure garbage in sealed bins. Reduce water availability by fixing leaky pipes and drying damp surfaces.
Third, deploy control devices. Choose from the following options, based on safety preferences and local regulations:
- Snap traps – positioned perpendicular to walls, with the trigger end facing the wall. Bait with peanut butter, chocolate, or dried fruit. Check and reset daily.
- Electronic traps – deliver a quick, humane kill. Place in concealed locations where activity is observed.
- Live‑catch traps – use only when relocation is permissible; release captured rodents at least 200 m from the property to prevent return.
- Rodenticides – apply in tamper‑proof bait stations, following label instructions and local law. Use as a last resort and keep away from children and pets.
Fourth, seal entry points. Inspect the building envelope for gaps larger than ¼ in. Common sites include:
- Gaps around utility penetrations
- Openings around doors and windows
- Cracks in foundation or siding
- Holes in vent covers and exhaust fans
Fill openings with steel wool, copper mesh, or caulk, then cover with cement, metal flashing, or expanding foam designed for rodent exclusion.
Fifth, maintain a hostile environment. Reduce clutter, store items off the floor, and keep vegetation trimmed away from the structure. Regularly vacuum and disinfect areas where droppings were found, using a solution of 1 part bleach to 10 parts water.
Finally, consider professional assistance if the infestation persists after these measures, if structural damage is evident, or if hazardous materials (e.g., disease‑carrying droppings) are present. Licensed pest control operators can conduct thorough inspections, apply advanced baiting systems, and provide warranties for continued protection.
