Mice in Sutton Homes: Signs, Treatment and Prevention

Two features come up again and again in Sutton's semi-detached houses: a loft that's easy to get into, and a garage with a connecting door through to the hallway. Both are common routes for mice.

Mouse Control Sutton: £190 flat / £240 house

The loft and the garage door

A great many of Sutton's 1930s and interwar semis were built with a garage set against the side of the house, linked by a connecting door, and a loft that runs continuously along a row of houses. Both give mice a way into the main living space without needing to find a gap at ground level.

Signs to look for

Droppings the size of a grain of rice near the garage door or skirting, a gnawed corner on stored food, and scratching in the loft or a wall cavity after dark are the usual first signs. A greasy smear low down along a regularly used route marks out where mice have been travelling.

Worcester Park's semis along the Kingston border

The interwar semis of Worcester Park, straddling the border with Kingston, follow the same pattern as much of the rest of the borough - garages, loft space and gardens all giving mice more than one way in, which is why checking every possible route matters rather than assuming just one.

Sutton town centre's older villas

Around Sutton town centre, the mix of Victorian villas and newer housing means older cellars and floor voids play more of a part than garages, giving mice a network to move through unseen.

What to do this week

  • Move dry food, pet food and bird seed into containers with a properly sealing lid
  • Check the garage connecting door and loft hatch as well as the kitchen for droppings
  • Pull the cooker or fridge out if you safely can, and clear what's built up behind it
  • Note where signs appear, and whether they return after cleaning
  • Keep an eye on cables and pipes behind appliances for fresh gnawing

Closing the gaps afterwards

Once activity has stopped, the garage connecting door and the loft hatch are usually the first places to check for gaps that need closing with materials a mouse can't chew through.
