Every autumn and winter, calls about rats and mice rise sharply across Somerset. As fields are harvested and temperatures fall, rodents move towards buildings looking for warmth, food and shelter. The good news is that most infestations can be prevented with a few simple checks.
Why rodents move indoors in winter
Rats and mice don't hibernate. When outdoor food becomes scarce and the weather turns cold and wet, lofts, cellars, garages and wall cavities offer ideal nesting spots. Rural and edge-of-town properties near farmland, rivers and the Somerset Levels often see the most activity.
A mouse can squeeze through a gap the width of a pencil, and a young rat through a gap not much bigger than a thumb, so even small openings matter.
Seal up entry points
Walk around the outside of your property and look for gaps at ground level and around pipes and cables. Common entry points include:
- Gaps where pipes and cables enter walls
- Damaged air bricks and vents
- Gaps under external doors and garage doors
- Broken drain covers and damaged drainage pipes
- Holes in soffits, fascias and roof edges
Remove food and shelter
Store pet food, bird seed and dry goods in sealed metal or hard plastic containers. Keep bins closed, compost bins well managed and avoid leaving food waste out overnight.
Clear clutter from garages, sheds and lofts, and keep log piles and garden waste away from the walls of the house.
Signs you may already have rodents
Look out for droppings, gnaw marks on wood or cables, greasy smear marks along skirting boards, shredded nesting material, and scratching or scurrying noises at night — especially in lofts and wall cavities.
