Why are there so many mice in London?

London is known as the mouse capital of Europe, with more mice than any other European capital. New Londoners often wonder - why does London have so many mice?

London is huge

Because London is a lot bigger than most European cities, it also has more mice

Architecture

London is a city with canals, waterways, and lots of old building with small spaces for mice to nest in. Explore

Seeing bags overflowing with rubbish is a common site on London streets. Other European cites have more sanitary waste management systems, limiting mice's food supplies.

London's poor waste management led to its mice infestation

Since the bubonic plague, London's attempts at waste management have always been a hair behind what is necessary. This delayed approach to waste management has attracted mice. Explore

Extended use of rodenticides has lead to resistance

Because of the widespread use of poisons to control London's rodent population, mice have become resistant to traditional rodenticides. Explore
