Where we find mice in East Grinstead
East Grinstead's mix of period properties, 1930s semis and modern estates means mice can enter through a variety of routes. Older homes around the High Street and Sackville area are particularly prone due to gaps around original pipework, aged mortar and original air bricks.
The surrounding woodland and countryside — towards Ashurst Wood, Forest Row and Felbridge — contributes to mouse activity, especially during autumn and winter when mice seek warmth and food indoors. Even newer properties can be affected, as mice can squeeze through gaps as small as 6mm.
