Why Mice Move Into Bromley's Homes
Airbricks across Beckenham's 1930s suburbia
The semi-detached houses that make up most of Beckenham and West Wickham were built with airbricks under the floor that deteriorate over the decades, giving mice a low, easy way into the void beneath. Once in, they follow the same route from house to house along near-identical terraces.
Shared walls in Bromley town centre's older terraces
Closer to Bromley town centre, older terraces split into flats give mice a similar corridor through shared party walls. Scratching heard in more than one flat usually means they're moving through a void rather than staying in one home.
Signs to Look For
- Small, dark droppings the size of a grain of rice, often near food
- Scratching or scuttling in walls, ceilings or under floors at night
- Gnawed food packaging, skirting boards or cables
- A musky smell in cupboards, drawers or under appliances
- Greasy rub marks along frequently used routes
- Nesting material — shredded paper or fabric — tucked in quiet corners
Mouse-Proofing After Treatment
It's the sealing-up afterwards, not just the treatment, that keeps a mouse problem from reappearing next year.
