Mice have appeared in an apartment building—what should be done? - in detail
Rodent activity in a multi‑unit building requires swift, systematic response. Identify the extent of the problem by inspecting common entry points, such as gaps around pipes, vents, and utility lines, and by looking for droppings, gnaw marks, and nesting material in kitchens, storage closets, and utility shafts.
Immediate measures focus on exclusion and sanitation. Seal all openings larger than ¼ inch with steel wool, copper mesh, or cement‑based caulk. Remove food sources by storing perishables in airtight containers, cleaning crumbs and spills promptly, and disposing of garbage in sealed bins. Eliminate water sources by fixing leaks and drying damp areas.
Control actions include trapping and baiting, applied according to safety guidelines:
- Snap traps: place along walls, behind appliances, and in concealed pathways; check daily and dispose of caught rodents promptly.
- Live‑capture traps: use for humane removal; release captured animals at least 5 m from the building, complying with local regulations.
- Anticoagulant bait stations: install in tamper‑resistant boxes, positioned out of reach of children and pets; rotate bait types to prevent resistance.
Professional pest‑management services should be engaged when:
- Infestation exceeds isolated sightings.
- Structural damage or health hazards are evident.
- Residents report repeated encounters despite DIY efforts.
A pest‑control contractor will conduct a detailed survey, apply rodenticides or electronic monitoring devices as needed, and provide a written action plan with scheduled follow‑up inspections.
Long‑term prevention relies on maintenance routines. Conduct quarterly inspections of building exteriors, reinforce door sweeps, maintain landscaping away from foundations, and educate occupants on proper waste handling. Document all actions in a log to track trends and demonstrate compliance with health‑safety standards.
