How can I get rid of spiders and mice? - briefly
Seal cracks, install door sweeps, and reduce clutter to prevent spider entry; use sticky traps, peppermint oil, or snap traps, and store food securely to eliminate mice.
How can I get rid of spiders and mice? - in detail
Effective control of arachnids and rodents requires a combination of sanitation, exclusion, and targeted treatments.
Maintain a clean environment. Remove food residues, crumbs, and pet waste that attract insects and mammals. Store pantry items in sealed containers, and keep garbage bins covered and emptied regularly. Vacuum corners, basements, and attics to eliminate spider webs and egg sacs.
Seal entry points. Inspect walls, foundations, doors, and windows for gaps larger than ¼ inch. Apply caulk, steel wool, or expanding foam to cracks around pipes, vents, and utility openings. Install door sweeps and weather stripping to block ingress.
Implement physical barriers. Use copper or aluminum foil under sink cabinets to deter rodents, as they dislike chewing metal. Place sticky traps along walls and behind furniture to capture spiders. For mice, set snap traps or live‑capture cages along established runways, typically within 2 feet of walls.
Apply chemical controls responsibly. For spiders, apply residual insecticide sprays to corners, baseboards, and dark areas, following label directions. For rodents, use bait stations containing anticoagulant or non‑anticoagulant poisons, positioned out of reach of children and pets. Rotate active ingredients to prevent resistance.
Consider natural deterrents. Sprinkle peppermint oil or cedar shavings in closets and crawl spaces; both emit scents that repel insects and small mammals. Deploy ultrasonic repellers in occupied rooms, acknowledging mixed efficacy but low risk.
Monitor and repeat. Conduct weekly inspections to verify that traps remain set, entry points stay sealed, and sanitation standards are upheld. Adjust tactics based on observed activity, and seek professional pest‑management services if infestations persist despite these measures.
