October marks the start of peak mouse season in the UK, with rodents seeking food and shelter in homes. After another unwanted encounter, one writer tried a simple hack recommended by experts: blocking entry gaps with steel wool. It worked so well that two weeks later, there have been no signs of mice.
Why steel wool works against mice
Mice are very small creatures, reportedly capable of squeezing through gaps no bigger than a pencil. Experts consistently advised blocking up gaps around the property where rodents might gain entry, with steel or wire wool as the preferred material.
The writer, living in an old building above a restaurant, had noticed holes throughout the kitchen. After spotting a mouse darting beneath the fridge, she tackled that area first, packing wire wool tightly underneath the built-in appliance.
Simple application and results
Steel wool is notoriously difficult for mice to gnaw through, making it an ideal deterrent. The writer packed it in as tightly as possible to prevent the mouse from dislodging it. Smaller gaps in the skirting board near the bin were sealed with electrical tape.
After a fortnight, there have been no signs of mice—no sounds and no droppings on the floor. Steel wool is non-toxic and safe to use, offering an alternative to poison or traps, though gloves are recommended as it can be sharp.
Considerations for long-term use
Steel wool can rust when exposed to moisture. To prevent this, copper mesh or stainless steel wool can be used instead, which should remain intact.
