Mouse infestations aren’t uncommon in the UK, especially in urban properties. The more people there are living in a given area, the more mice you will find there. This is because human settlements provide plenty of food and shelter; residing in people’s homes is much safer than living outdoors for mice, despite all the cats. If you live in a built-up urban environment, you should be taking steps to ensure you aren’t inadvertently providing local mice with any free meals. If they find food in and around your home, they’re much more likely to find a way in and build a nest. Depriving mice of food is one of the most effective ways of keeping them away from your home and encouraging them to leave once they have already set up shop.
Mice can live off tiny amounts of food, but they need to eat regularly; their small digestive systems mean they start craving their next meal after just a few hours. Their ability to exploit narrow gaps and cracks to gain access where they aren’t wanted enables mice to seek out food wherever it’s available.
Mice survive on small amounts of food regularly rather than relying on big feasts to fill them up. Mice can’t survive longer than two to four days without food. Many animals will eat full meals that give them sufficient energy until their next meal. But mice are different; they are scavengers. Mice eat what they can when they can. Even a few small bites on something edible can sustain a mouse for those vital few hours.
If you want to keep mice off your property, you need to clean up after yourself and avoid leaving food around for mice to find. Mice will happily eat scraps from bins; ensure you properly seal and secure yours.
