The Super Rat Struggle: Rodenticide Resistance and a More Ethical Approach to Pest Control

The UK is facing a growing problem: super rats. These aren’t giant, mythical creatures, but rather ordinary rats that have developed resistance to commonly used rodenticides. This resistance makes it harder to control rat populations, leading to infestations that are more difficult and costly to manage. But what’s causing this resistance, and what can be done about it?

The Rise of the Resistant Rat:

Rodenticides, or rat poisons, have been a staple of pest control for decades. However, their widespread and often indiscriminate use has led to the evolution of rats that are no longer susceptible to their effects. This is known as rodenticide resistance. Essentially, the rats’ bodies have adapted to break down or tolerate the poison, rendering it useless.

What Fuels Rodenticide Resistance?

Several factors contribute to the rise of resistant rats:

• Overuse: The more rodenticides are used, the greater the selective pressure on rat populations. Rats that are naturally more resistant are more likely to survive and reproduce, passing on their resistance genes to future generations.
• Sub-lethal Doses: If rats consume sub-lethal doses of rodenticide (not enough to kill them), they may develop resistance over time. This can happen if bait is poorly placed or if rats only consume small amounts.
• Lack of Variety: Continuously using the same type of rodenticide also contributes to resistance. Rats can develop cross-resistance, meaning they become resistant to other similar rodenticides as well.

The CRRU Guidelines: Trapping First

The Campaign for Responsible Rodenticide Use (CRRU) has established guidelines to minimise the development of rodenticide resistance and protect non-target wildlife. A key principle of these guidelines is to prioritise non-chemical methods, such as trapping, as the first line of defence against rats.

Why Trapping Matters:

• Reduces Reliance on Rodenticides: Trapping allows you to remove rats without introducing poison into the environment. This reduces the selection pressure that leads to resistance.
• Humane and Targeted: Trapping can be a more humane method of control, especially when using appropriate traps and checking them regularly. It’s also more targeted, reducing the risk to other animals.
• Identifies the Problem: Trapping can help you understand the scale of the infestation and identify potential entry points or attractants.

The Unscrupulous Pest Controller:

Unfortunately, some pest control companies prioritise profit over responsible pest management. If a pest controller’s first and only solution is to scatter rodenticide without exploring other options, it should raise a red flag. This approach is not only ineffective in the long run due to resistance but also poses risks to wildlife and the environment. A responsible pest controller will always consider trapping and other non-chemical methods first, adhering to CRRU guidelines.

Green Pest Control Services: A Responsible Approach

At Green Pest Control Services, I take a responsible and ethical approach to pest control. I adhere to CRRU guidelines and prioritise trapping as my first line of defence against rats. We understand that long-term, effective pest control requires a comprehensive strategy, not just a quick fix with poison. We’ll work with you to identify the source of the infestation, implement preventative measures, and use trapping as the primary method for removing rats. Only when absolutely necessary and as part of an integrated pest management plan will we consider the targeted use of rodenticides, and always in accordance with CRRU best practices. Contact me today for a sustainable and effective solution to your rat problem. Don’t let unscrupulous practices create super rats on your property.
