Mice infest buildings from the foundations up to the roof, crawling and climbing through gaps in the walls, along cables and piping, under floors, above ceilings and through roof spaces. They can dig, climb, jump and squeeze through gaps as small as 6mm. And they’re active all year round. They’ll chew everything they come across because their front teeth are always growing and constant nibbling stops the teeth from getting too long.
Signs of mouse infestation
The clues are small, dark droppings, nibbled pipe insulation or foods, chewed paper and nasty smells from mouse urine or dead mice. Look under kitchen units, in boiler and electric cupboards, in store rooms and under cover outside. You may hear them scampering about in the walls and ceiling spaces, especially at night.
