Rat Poison Resistance Seen In The UK

Rats are one of the most detested pests in the UK. And for many UK home and business owners they are more than just a nuisance. They are upsetting to have around, and also pose a serious risk to human health and safety. Normally, we are able to put down rat poison and handle a minor infestation in the conventional way.

However, some of these pests have developed a rat poison resistance in recent years, making these “super rats” harder to treat.

What Rat Poison Resistance Involves

Rat infestations have been prevented and controlled using poisons for centuries. But because of the overuse of these poisons, the rat poison resistance in these animals is on the rise. Simply put, rat poison resistance means that many them have an immunity to normal rat poison pellets. In fact, immune rats are even using these pellets as a food source and sustaining rather than curtailing the population.

In Britain alone there is around 10.5 million rats. The rat is a mammal that constantly breeds. And an increasing proportion of rat species are resistance to normal household rat poisons. This could result in the number of rats in the UK doubling or even tripling in size if the issues isn’t addressed.

Defeating The Poison Resistant Rat

The fact that these super rats are so resistant to poison also results in them becoming hardier, larger and more robust in general. Stronger poisons are now needed to control this type of super rat, but they are not readily available over the counter.

Only licensed pest control professionals like Diamond should be treating any major rat infestations. This is because we are qualified to administer more powerful rodenticides, and are experienced with effective new methods that can treat a rat infestation effectively.

Rat poison immunity also means that pest controllers are using other methods to control the UK rat population. Among the most efficient equipment we have at our disposal are professional traps and baiting stations.

Rats Can Go Undetected

In London, it is said we are never more than 6 feet from a rat at any time. Despite this, you will rarely run into a rat during the day, and they keep a low profile at night too. Rat problems often go unnoticed until it is too late. This is because the small signs they leave behind can be hard to spot. However, there are signs you can keep an eye out for if you suspect a rat problem.

Check for droppings, gnawing marks and chew holes around the home, as well as greasy smears left from their fur. If rats are living in your attic, you may be able to hear them scratching when they become active at night.
