Rodents, such as mice and rats, can:

There are a number of chemical and non-chemical methods for controlling rodents, such as:

Biocidal products that control rodents by attraction (like traps) are covered by product type 19 of the GB Biocidal Products Regulation (GB BPR). Biocidal products that control rodents by other means, such as poisons, are known as rodenticides and are covered by product type 14.

Rodenticides authorised for use in Great Britain

Types of rodenticides authorised for use in Great Britain include:

Details of the individual rodenticide products authorised for use in GB can be found on the GB List of Authorised Biocidal Products.

Depending on when and where they are used, some rodenticides might not be controlled under GB BPR, for example, if they are used on crops in the field they might be controlled under the GB Plant Protection Products Regulation (GB PPPR).


By their nature, all biocidal products carry potential risks to people, non-target animals and / or the environment. Rodenticides can often carry a higher risk than some other biocidal products because the way that they are used and how they look and smell, might mean that children, pets and other non-target animals are more likely to be harmed by them.

Rodenticides can be grouped according to their mode of action ie the way that they work. The mode of action of a biocidal product usually depends on the active substance it contains. One of the most commonly used groups is the anticoagulant rodenticides.

Risk assessments carried out by regulators, including HSE, have shown that anticoagulants present a higher risk to people and non-target animals than is normally acceptable for authorisation in Great Britain.

Under GB BPR, products with unacceptable levels of risk may still be authorised if it can be shown that the negative impact on society of not allowing their use would outweigh the risks of using them. However, this can only be done if the risks can be minimised with specific measures.

One of the ways of minimising these risks is to minimise the use of anticoagulants wherever possible. If you need to deal with a rodent problem, it is important to remember to consider other available control methods, such as those listed above, before reaching for anticoagulant products.

However, it is recognised that alternative methods may have limitations, and some may not be suitable to be used in certain locations or by some types of users. Effective strategies for controlling rodents are therefore based on having a wide range of options available, including both chemical and non-chemical methods.

As biocidal products are recognised as being one of this range of options necessary for the effective control of rodents, it is also important to ensure that their effectiveness is maintained. If rodent populations build up resistance to biocidal products, our ability to effectively control them could be significantly reduced. The two main strategies in minimising this are:

To maintain effective rodent control, it is therefore appropriate to continue to have as full a range of methods available as possible, including the anticoagulant rodenticides. The danger and economic costs of rodents spreading diseases, damaging property and disrupting food supplies and the negative impact that would have on society mean it is appropriate to authorise anticoagulant rodenticides, but with strict controls to help minimise the risks.

General public users

In order to ensure rodenticides are used as safely as possible by the general public, rodenticide products may be restricted in ways such as:

Professional users

In order to ensure rodenticides are able to be used as safely as possible by professional users, rodenticide products may be restricted in ways such as:

Additionally, the use of anticoagulant rodenticides by professional users in Great Britain must follow the requirements of one of the UK rodenticide stewardship regimes.

UK rodenticide stewardship regimes

In order to ensure that the risks associated with the professional use of anticoagulant rodenticides are able to be properly managed, manufacturers, users and other stakeholders were invited to look for ways to manage and improve good practice by professional users and in other areas such as the supply chain. This led to an agreement between stakeholders and the UK Government for the need for rodenticide stewardship.

Regime principles

The UK Government set out a number of principles that should form the basis of any industry-led stewardship regime:

The UK Rodenticide Stewardship Government Oversight Group (GOG) is responsible for reviewing the regimes to ensure the principles set out by the UK Government continue to be met. HSE chairs the GOG and other representatives include:

The GOG releases an annual report on rodenticide stewardship which can be viewed below.

Existing UK rodenticide stewardship regimes

Campaign for Responsible Rodenticide Use UK (CRRU UK)

The Campaign for Responsible Rodenticide Use UK (CRRU UK) has developed a stewardship regime in the UK that meets the regime principles set out by the UK Government.

The CRRU UK regime was developed with a number of different industry sectors, including:

The CRRU UK regime includes a framework of:
