As temperatures drop through October, mice start looking for somewhere warm and quiet to shelter — and garages, sheds and parked cars are some of their favourite spots. We’re seeing this pattern every autumn across Beeston, Chilwell and Stapleford, and the same thing happens along the Erewash Valley in Long Eaton and Sandiacre, where commuters leave cars standing for long stretches at the station car parks.
Why mice head for engine bays and garages
A car engine bay offers exactly what a mouse wants once it cools down from a drive: tight gaps around the wheel arches and air intake, insulation to shred for nesting material, and shelter from wind and rain. Cars left parked for a full working day or longer — such as at the big commuter car park by Long Eaton railway station, or the tram and train interchange in Beeston — are particularly attractive, since nothing disturbs the nest while the owner is away. The same applies to garages and sheds in Chilwell and Stapleford that back onto gardens, allotments or the Erewash Canal, all of which give mice a sheltered route in from the outside.
Signs mice have moved in
- A strong, musty smell when you open the bonnet or garage door
- Shredded paper, insulation foam, leaves or loft insulation packed around the air filter housing or under the bonnet liner
- Droppings (small, dark, rice-grain sized) on the garage floor, shelving or car seats
- Chewed wiring looms, washer pipes or air filter housings — this is the one that causes real damage, since a chewed loom can mean a failed MOT or, in rare cases, an electrical fire risk
- Scratching or rustling noises from the engine bay shortly after the car has been parked up
Reducing the risk
A few simple habits make a real difference. Where possible, start the car and let the engine idle briefly every day or two if it’s going to sit for a while — mice are far less likely to nest somewhere that gets disturbed regularly. Keep garage doors and up-and-over seals in good repair, since even a small gap under a door is enough for a mouse to squeeze through. Don’t store birdseed, pet food or garden bulbs in a garage or shed, as these are exactly what draws mice in from the garden in the first place. Peppermint-soaked cloths tucked near (not on) wiring can help as a deterrent, though they’re not a substitute for proper proofing once mice are already established.
When it’s more than one car
If mice have found their way into a garage attached to the house, the risk isn’t limited to the car — they’ll often use the same entry points to get into wall cavities, loft spaces and kitchens once the weather turns properly cold. This is especially worth checking in the older semis and terraces common across Beeston, Chilwell and Stapleford, and in the Victorian and Edwardian housing nearer Long Eaton town centre and Sandiacre, where airbricks, old pointing and worn door thresholds all give easy access.
We proof garages, sheds and the points where pests get from the garden into the house itself — identifying and sealing entry points, fitting proofing to vulnerable gaps, and dealing with any nest that’s already established inside the property. We don’t work directly on vehicles, but a proper job on the garage and the surrounding entry points removes the shelter that’s drawing mice in near the car in the first place, which is usually what actually solves the problem.
