What should I do if there are field mice in the house? - in detail

Field mice entering a residence indicate a breach in the building envelope and a source of food or shelter that attracts them. Begin by locating entry points: examine the foundation, exterior walls, windows, doors, and utility penetrations for gaps larger than a quarter‑inch. Seal openings with steel wool, caulk, or hardware cloth, and repair damaged screens.

Next, remove attractants. Store food in airtight containers, clean crumbs and spills promptly, and keep trash in sealed bins. Eliminate water sources by fixing leaks and drying damp areas such as basements, crawl spaces, and under sinks.

Implement a trapping program. Choose snap traps or electronic traps positioned along walls, behind appliances, and in concealed pathways. Bait with high‑protein foods such as peanut butter or dried fruit. Check traps daily, dispose of captured mice hygienically, and reset traps until activity ceases.

If trapping proves insufficient, consider bait stations containing anticoagulant rodenticides. Use only in accordance with local regulations and follow label instructions to prevent accidental poisoning of non‑target species and humans. Place stations in tamper‑resistant units, away from children and pets.

Maintain a long‑term exclusion strategy. Install door sweeps, repair weather stripping, and ensure that vents and ducts have appropriate mesh screens. Conduct periodic inspections, especially after seasonal changes that may drive rodents indoors.

When infestations persist despite these measures, engage a licensed pest‑control professional. They can conduct a comprehensive assessment, apply advanced control techniques, and provide a monitoring plan to prevent re‑infestation.
