Stewardship Regime

CRRU UK Chairman Dr Alan Buckle says, “CRRU UK welcomes the opportunity to co-ordinate this important UK-wide stewardship initiative. We have to get smarter in the way we use rodenticides – and show we are doing so. It is now up to suppliers and users of these essential products to demonstrate that they can be applied without unacceptable effects on UK wildlife and other non-targets.”

Why do we need stewardship?

Anticoagulant rodenticides fail conventional regulatory risk assessments.  Residues are found in a wide variety of wildlife species and they are occasionally responsible for deaths of non-target animals.  The Health and Safety Executive (HSE), as the UK Competent Authority for biocides, requires reassurance that products containing these substances can be used without unacceptable risk to wildlife and other non-target species.

Development of the regime

In late 2012, HSE invited comments from stakeholders and other interested parties on a document setting out options for environmental risk mitigation measures for rodenticides in the UK. In April 2013, it held a meeting with stakeholders to discuss their responses. The conclusion of this consultation was that future use of rodenticide baits required a stewardship regime involving all main rodenticide user groups, including pest control professionals, local authorities, farm and land managers and gamekeepers.
HSE asked the Campaign for Responsible Rodenticide Use (CRRU) UK to co-ordinate the development and delivery of the stewardship regime, in collaboration with organisations from all user groups. The HSE document issued to describe the regime and the role of CRRU is available here.

The UK Rodenticide Stewardship Regime

The regime was launched in July 2015 and encompasses all rodenticide products sold to and used by professionals when applied outside buildings. It does not involve rodenticides restricted to use indoors, nor fumigant gases which are the responsibility of the Register of Accredited Metallic Phosphide Standards (RAMPS) ( It also does not involve rodenticide products sold to and used by amateurs. HSE will issue new requirements for the authorisation of rodenticide products in alignment with the stewardship regime.

High Level Principles

A successful stewardship regime must meet ‘high level principles’ set out down by HSE (Please click HERE)

  1. Using Integrated Pest Management, including use of rodenticides, involving a hierarchy of risk controls for rodents;
  2. Using rodenticides responsibly, when demonstrated they are needed, because of their potential threat to human, animal health and the environment;
  3. Being applicable to all suppliers, handlers and professional users of rodenticides approved under stewardship to address these risks;
  4. Being robust, effective and workable, while remaining as simple as possible;
  5. Covering the whole life-cycle of the rodenticide products: manufacture, supply chain, end-use, disposal and environmental fate;
  6. Enabling good practice in the control of rodent populations as part of an integrated pest management system, while minimising resistance build-up and secondary poisoning in non-target species;
  7. Delivering key benefits such as:
    • governance of the supply chain, which gives governance over and provides the driver for later stages;

    • a competent workforce capable of delivering stewardship standards and of demonstrating an appropriate understanding and attitude toward case-specific control of rodents and use of rodenticides; and

    • monitoring compliance with the regime and its environmental impacts, and if possible of t he level of conflict reduction – i.e. an assessment of whether rodenticides and stewardship together are actually tackling the problems.


To deliver the regime CRRU UK has set up a structure of six Work Groups which each comprise representatives from CRRU UK and user organisations, as well as technical experts. The composition of these groups and their remits can be seen here.

Code of Best Practice

The cornerstone of the regime is a Code of Best Practice for the use of rodenticides published by CRRU UK in early 2015. Application of rodenticides according to the code will prevent unnecessary exposure of wildlife and other non-target animals and help deliver the objectives of the regime. The code is available here.

Use patterns

Rodenticides will be authorised for professional use in three main areas (for definitions of these use patterns refer to the CRRU UK Code of Best Practice available here):

  • ‘Indoors’. Products authorised ONLY for use indoors will not be required to conform to ‘stewardship conditions’.
  • ‘In and around buildings’. This use includes an ‘outdoor’ element and therefore all professional products authorised for this use will be subjected to ‘stewardship conditions’.
  • ‘Open areas’. This use pattern involves only ‘outdoor’ use and all professional products authorised for this use will be subject to ‘stewardship conditions’. It is generally considered that this use pattern carries with it the greatest risk of accidental exposure to wildlife.


HSE has asked CRRU UK to fund and conduct a series of studies to monitor implementation and impacts of the regime:

  • Levels of anticoagulant residues in the livers of UK barn owls will be monitored annually. HSE will expect to see a significant decline in the proportion of barn owls carrying rodenticide residues and a reduction in the concentration of residues in the owls’ bodies as a result of stewardship implementation.
  • The breeding success of selected barn owl populations will be studied to determine impacts, if any, of rodenticide use.
    A periodic survey will be conducted on the knowledge, attitudes and
  • practices of all professional rodenticide users in order to observe changes over time in these important criteria. A baseline survey has already been conducted in advance of regime implementation.

What if it doesn’t work?

HSE has an option to introduce more stringent regulation if deemed necessary because the effects of stewardship on non-target organisms are found to be insufficient. These may involve further restrictions on who can use professional rodenticides and where they can be applied.

  • Co-ordinate among rodenticide manufacturers to simplify and harmonise product labels.
  • Co-ordinate implementation of checks for proof of competence at point-of-sale with the time-table for product authorisation.
  • Ensure, where possible, that products with similar properties and patterns of use carry similar labels wording to reduce confusion and complexity, and promote the same core set of mitigation measures.
  • Provide stewardship monitoring data to HSE as a requirement of product authorisation (such data subject to agreed confidentiality and ownership structures).

Point of Sale


  • Implement the stewardship regime’s core requirement for proof of competence at the point-of-sale for rodenticide baits.
  • Work with all rodenticide distributors (including internet businesses) to ensure installation of mechanisms at point of sale to check that stewardship-approved qualifications are fulfilled by all purchasers and users of rodenticide baits.
  • Address with distributors the issue of centralised purchasing of rodenticide baits and their subsequent use by qualified field operatives.
