Britain is facing the wettest winter recorded in 130 years and the extreme rainfall is having very destructive consequences such as flooding. This weather is not only damaging homes and businesses, but also bringing another problem…rats!
Usually, the rat population decreases over the winter due to frost and cold conditions. However, the unusually mild winter has meant rats haven’t had to endure a cold climate. Without this natural form of population control, numbers have increased. Flooding means they are being driven out of natural burrows as well as sewer and drainage systems.
How do rats survive flooding?
Rats are extremely well adapted to water. They can swim up to half a mile and tread water for three days! By using their tails as a rudder, they can swim to safety and then seek a new home.
Why do our homes become the perfect refuge?
During the winter months, rats are already on the hunt for warm places to seek shelter. Many find refuge in sewers as they make the perfect habitat offering food, water and safety from predators. But now they are being flushed out of sewers and drainage systems there will be an increase of rats wanting to find new homes.
Flood-damaged buildings soon become the prime target as there are plenty of entry points for rats to take advantage of. There is also rubbish and debris that accumulate after a storm which make perfect hiding places for rats.
Flooding can also wash away a rat's natural food source, this prompts them to search for new food sources which are often in our homes.
Increase in Weil’s disease
Weil’s disease (or Leptospirosis) is spread in the urine of infected animals, most commonly rats. The disease has flu-like symptoms which can be easily treated but can make some people seriously ill. The disease is transported through water, so areas of flooding become high risk. It’s imperative that flooded areas are washed down and treated with bacterial biocide.
