Ah yes, should have said. You need to cover all air bricks, vents and holes that are within a metre (or perhaps more) of the ground with a wire mesh with holes that are too small for a mouse to get through. They can wriggle through the tiniest of gaps and chew around to make the hole bigger. Pest control companies are experts at this but if you DIY, make sure it’s a strong wire mesh with fairly small holes (perhaps max 1x1cm).
