Autumn Rodent-Proofing Checklist for Homes and Businesses

A gap beneath a garage door, a damaged vent or an open bag of bird seed can be easy to overlook when rodent-proofing your home or business.

An autumn property check is a useful opportunity to spot these small problems and put them right before rats or mice find their way inside.

This checklist takes you around the outside of your building, through food and waste areas, and into the storage spaces that are often left undisturbed. Use it to record what needs attention, arrange repairs and identify anything that needs a professional inspection.

For the background to seasonal rodent activity, read our guide to why mice and rats head indoors in autumn.

Before you start

Take a torch, your phone and something to record any problems. Photograph areas that need attention so you can find them again or show them to a contractor.

Carry out external checks in daylight and inspect only places you can reach safely. Leave roof work, drainage investigations and inaccessible spaces to a suitable professional.

If you suspect animals are already using an opening, get advice before sealing it. Proofing needs to be coordinated with any necessary treatment to avoid trapping animals inside.

1. Check external doors and garage doors

Start at the front door and work around every external entrance, including side doors, rear doors and garages.

• Check beneath closed doors and around their frames for gaps.

• Look for damaged thresholds, worn seals and gnawed edges.

• Check the bottom corners of garage doors, where gaps can be easy to miss.

• At business premises, check whether loading doors are routinely left open.

Action: Record damaged fittings and arrange repairs or suitable rodent-resistant door proofing. Do not assume a narrow gap is harmless: mice can enter through very small openings.

2. Inspect pipe entries, vents and air bricks

Follow the outside walls, paying particular attention to places where pipes and cables enter the building.

• Look for gaps around plumbing, utility cables and waste pipes.

• Check for broken air bricks, loose vent covers and damaged surrounding brickwork.

• Revisit areas where recent building or installation work may have left openings.

Action: Have gaps repaired using materials suitable for rodent proofing and the building itself. Keep essential ventilation, drainage and appliance openings functioning correctly. If you are unsure whether an opening can be covered, seek advice before altering it.

3. Look at rooflines and the surrounding area

From ground level, look upwards as well as along the base of the walls.

• Note visible damage around eaves, soffits and roof edges.

• Check for vegetation touching the building.

• Look for piles of timber, unused equipment or other clutter against external walls.

• Check visible drain covers for damage or poor fitting.

  
  

Action: Clear accessible clutter and arrange appropriate maintenance. Ask a suitable contractor to investigate roof-level defects or suspected drainage problems rather than attempting to seal them yourself.

4. Check bins and waste storage

Inspect the bin area as part of your walk around the property.

• Make sure lids close properly.

• Look for splits, holes or damage around the base of bins.

• Check behind and beneath bins for spilled food.

• Identify any overflow that leaves rubbish bags outside containers.

Action: Clean up spillages, replace damaged bins and make sure there is enough waste-storage capacity between collections. For businesses, include the bin area in routine cleaning checks and assign responsibility for reporting problems.

5. Review food, pet food and bird-seed storage

Move indoors and check the places where food is kept, including garages, sheds and utility rooms.

• Check opened packets of dry food and pet food.

• Inspect bird-seed bags and any stored animal feed.

• Look beneath accessible shelving for spillages.

• Check containers for damaged lids or signs of gnawing.

• If you feed garden birds, inspect the ground beneath feeders for accumulated seed.

Action: Use robust containers with tightly fitting lids, clear spilled food promptly and replace damaged storage containers. At commercial premises, include delivery packaging in your checks before moving stock into storage.

6. Inspect lofts, garages and quieter storage areas

Only enter spaces with safe access. Use your torch to inspect accessible edges and corners without disturbing suspected nesting material.

• Look for droppings, gnawed packaging or shredded materials.

• Check accessible areas behind shelving and stored belongings.

• Note disturbed insulation or damage to stored items.

• Record repeated scratching or movement sounds, including where and when you hear them.

Action: Keep storage organised so changes are easier to spot. Where practical, leave access for inspection and use lidded containers rather than loose cardboard boxes. If you find possible rodent activity, pause the clear-out and seek advice.

7. Make a repair list and follow it through

An inspection is most useful when the findings lead to action.

For each problem, record:

• Where it is and what you found.

• A photograph, where helpful.

• The repair or advice needed.

• Who will deal with it and when.

• Whether the work has been completed.

For a home, a short list on your phone may be enough. For a business or managed property, a shared record helps prevent maintenance jobs being overlooked.

Revisit repaired areas to check the work is complete, and repeat relevant checks after building work, damage or new signs of activity.

Found signs of rats or mice already inside?

If you find droppings, gnawed food packaging, suspected nesting material or repeated unexplained noises, the next step is to establish what is happening. Closing visible gaps alone may not resolve an existing infestation.

Avoid disturbing suspected contaminated material and keep children and pets away from affected areas while you arrange advice.

A professional inspection can help identify the pest, investigate access routes and establish what treatment, repairs and monitoring are needed.
