Why So Many Cockroaches in London?

Cockroaches in London are a major problem. They can plague residential and commercial properties alike. They cause diseases and contamination.

In fact, it can sometimes seem as if there are more cockroaches in London than people. Which there probably are.

But why are there so many cockroaches in London? There are a few good reasons:

Cockroaches are hard to get rid of

These are one of the hardest pests in the world to get rid of. They are good at surviving, and eliminating them completely is a difficult task. As soon as you remove one cockroach nest, another seems to pop up almost immediately. Even if you burnt down the entire city, the cockroaches in London would survive.

There are thousands of eateries

These range from your local café, to curry emporiums to five star restaurants. And all of these establishments have kitchens and rubbish bins.

This means that every single one of them is a perfect magnet for cockroaches. Food businesses have to be particularly vigilant when it comes to these pests.

London is a damp city

Cockroaches love to live in dark wet places. London is literally the perfect habitat for them. There are a million nooks and crannies where these creatures can hide. London is so massive, that it’s literally impossible to find and eliminate all of these creatures.

There are millions of people

London is home to millions of people. This means there are endless flats and kitchens for cockroaches to live and breed in. Very few people keep their homes spotlessly clean. This means cockroaches are surrounded by an endless buffet of food.

Cockroaches in London are a hidden problem

Londoners have extremely busy lives and are constantly on the go. Very few people actually know much about these pests. Cockroaches spend their lives hiding away in the dark.

This means you can go years without seeing cockroaches in London, which leads to ignorance about the true scale of the problem.

London is an international city

Trains, ships and lorries come into London from all over the world – all day every day. It’s highly likely that many of these transporters are unknowingly bringing cockroaches into London. This means that the problem will continue to me huge.

Immunity to extermination

Over the decades, these hardy insects have evolved. And during that time, as part of their evolution, they have built up a tolerance to many pesticides. Most cockroaches in London simply thumb their noses at humans. To eradicate them successfully, exterminators need to really know what they are doing. Luckily, here at Diamond, we do!
