The story of rats in London

Rat control in London is quite a modern concept and it has allowed to reduce dramatically the incidence of disease anong the residents population. Rats have been a part of London for centuries; in fact, aside from pigeons, theyre probably the animal you most associate with London. Rats (and the fleas/germs they carry) have long been a major problem for London, spreading dirt and disease, including the deadly plagues of the Late Middle Ages. While the problem is far less severe today, rats still do pose a threat to our sanitation and hygiene. How many rats in London we have nowadays is anyone’s guess. In this article, were going to tell a brief history of rats in London and what the present-day situation is like for the capital. Just how worried should you be about the number of rats in and around Londons homes today? 

The First Settlers (First to Third Century)

Rats first came to Britain from Asia almost two thousand years ago on Saxon ships and quickly spread across the entire European continent. London became a popular destination for rats due to the relative abundance of shelter, warmth, and food scraps, thanks to London being a more developed area. Over the centuries, rat numbers steadily grew, and rats continued to stowaway on ships from Asia and arrived in Europe.

The Black Death (Fourteenth Century)

The Black Death was one of the deadliest pandemics in human history, claiming up to 50% of Europes population and countless more in the Middle East between 1347 and 1351. Its believed to have originated in Central Asia and been transported to Europe by traders along the Silk Road and on ships from Asia to Europe. The exact vessel? Its generally thought that the fleas on rats were the carriers, and the large population of rats in Europe were to blame for the disease spreading so quickly.

The Great Plague of London (Seventeenth Century)

In 1665, shortly before the Great Fire of London in 1666, the Plague struck London again. The Great Plague was once again spread by the fleas on rats, and it claimed approximately a quarter of Londons population. Thankfully, the Great Plague marked the end of the era of major bubonic plague outbreaks in England. While rats werent directly responsible, their connection to the disease is undeniable. Its a large part of the reason we still strongly associate rats with the disease.

Sir Henry Cole’s Rat (Nineteenth Century)

Rats havent always been the bane of London life; in fact, rats indirectly helped to improve the way we store records. This is the peculiar tale of the rat affectionately known as belonging to Sir Henry Cole. Britains public records were once kept in an old stable in London. Of course, these records were kept on paper, and stables are notoriously damp places. Fairly soon, Sir Henry Cole, a civil servant, saw that the papers were sticking together and rotting, and attracting a lot of rats.

He found a dead rat whose stomach contained some of these records, and he used this as evidence of the poor conditions in which the public records were kept. This led to the official Public Records Office, now known as the National Archives. The rat in question has been preserved, as is on display in the National Archives. You could argue that if it wasnt for that rat, it could have been many more years before record-keeping methods were improved.

Rats in London Today

Today, the threat of Plague or destroyed records is virtually non-existent, but rats are still a big part of London. Many facts” and statistics” are thrown around regarding the number of rats in London. One of the most famous is that there is one rat for every human in Britain.

How many rats in London are there?

This statistic has been quoted for a hundred years. It comes from an estimate of the rat population in 1909, where a survey was conducted regarding whether people thought it was reasonable to assume there was one rat for every acre of land. As it happened, there were approximately 40 million acres of cultivated land at the time and approximately 40 million people living in Britain. Since then, that statistic” has been stuck in the public psyche without proper scrutiny.

Its challenging to accurately measure how many rats there are in London or the UK, but current estimates suggest there are approximately three million rats in urban areas of Britain. While this is far fewer than one rat for every human,” its still a huge number. In fact, sightings of rats in London are on the increase. Londoners are making over one hundred complaints per day to authorities regarding rat sightings in and around their property, and that number has been rising over the past few years. This highlights the importance of proper pest control.

Why do we have so many rats in London affecting our homes?

If I had to give a single reason why so many Londoners are suffering from rat activity within their homes, it would be the deteriorating conditions of our sewer network. Most of it has been built in the Victorian Age, and the key ingredient was the novel use of Portland cement, which has a half-life of about one hundred years.

Fast forward one hundred years to modern times, and we end up with Thames Water having to repair and/or maintain a number of collapsing drains and manholes. There are also a multitude of other issues that added to this crisis. Many rodding eye caps have gone missing; originally made of terracotta and held with a chain, they have either broken, or the technician had forgotten to put them back. Then we have modern contractors who rely on plastic pipes with various degrees of integrity and skills.

And finally, we have a number of houses that are connected to the main sewers, but we lost the records of how they are connected, or of where the manhole actually is. Most of our clients who suffer from rats under the floorboards can actually trace the primary route of access to the inspection chamber they normally find at the front or at the back of their property. Placing a no-return valve there is often the solution to stop rats from getting through later on.

But in the instance where neither the inspection chamber nor the manhole can be identified, the client ends up suffering ongoing infestations year after year or has to resort to extreme measures that are both expensive and risky. Many properties have sold in the past because the occupiers could not come to terms with the rat infestation. Rats are here to stay, and there is no easy fix on sight. Rats in London are part of our history, and they will not go away ever. We can even come across extreme rat infestations affecting restaurants.
