Mouse Control Merton: £190 flat / £240 house

Suburban semis with garages and outbuildings

Suburban semis with garages and outbuildings around Raynes Park and Morden give mice a way into the main house unseen, since a garage is rarely checked as often as the kitchen and can act as a quiet staging post before mice move indoors.

Signs to look for

Droppings in a cutlery drawer, a nibbled cereal box, or scratching in the roof space above a garage or utility room are the usual first signs, and worth checking even if the main house seems untouched.

Wimbledon's larger converted houses

In the larger Victorian houses near Wimbledon Common that have been split into flats, mice travel through old floor voids and service risers that predate the conversion, so noise in one flat can start in a neighbour's.

What to do this week

  • Move dry food, pet food and bird seed into sealed containers
  • Pull out the cooker or fridge if you safely can, and clear what has built up behind it
  • Note where droppings appear, and whether they return after cleaning
  • Ask your neighbours, landlord or managing agent whether anyone else has seen signs
  • Keep an eye on cables and pipes behind appliances for fresh gnawing

Closing the gaps afterwards

In a semi, that is often the garage and utility room; in a converted house, it is more often the party wall or the old service risers.
