The Rising Rodent Threat to UK Farms and What 2026’s New Rodenticide Rules Mean for Your Business

Rodent activity on UK farms is increasing, and the threat they pose to agricultural businesses has never been more serious. Recent reports highlight a worrying rise in infestations, escalating resistance to traditional control methods, and major regulatory changes arriving in January 2026.
For farmers, estate managers and rural business owners across Hertfordshire, Bedfordshire, Buckinghamshire and the wider region, staying ahead of these challenges is essential for protecting crops, livestock, staff and long-term business reputation.
Rodent Numbers, and Resistance, Are on the Rise
A 2025 report from FarmingUK revealed a sharp increase in rodent sightings and damage across UK farms. According to the article, the re-launched Rodenticide Resistance Action Committee (RRAC) survey shows growing evidence of rats and mice developing resistance to commonly used anticoagulant rodenticides. This means that products which once worked reliably may now be significantly less effective in certain areas.
For farms, the consequences are far-reaching. Rats and mice eat and contaminate feed, damage equipment and machinery, destroy wiring, and undermine buildings. They can spread diseases harmful to both humans and livestock, including leptospirosis, salmonella and toxoplasmosis. At a time when profit margins are already tight, the financial impact of an unchecked infestation can be devastating.
Major Rodenticide Law Changes Coming in January 2026
Adding to the challenge is a major shift in UK rodenticide regulations coming into force from January 2026. As highlighted in Red Tractor’s recent update, farmers and pest control professionals will face new requirements when purchasing rodenticide products.
Under the new rules:
Anyone buying professional-grade rodenticides must demonstrate competence through approved certification.
Suppliers will be legally required to verify qualifications before selling products.
Farms will be expected to follow stricter record-keeping, usage protocols and environmental stewardship measures.
These changes are designed to protect wildlife, reduce misuse and slow the spread of resistance. However, they also mean that farms relying on ad-hoc rodent control or older methods will need to update their approach.
Working with a qualified pest management company such as Stratton Pest Control ensures full compliance with 2026 regulations, while also providing safer, more effective and longer-lasting control solutions.
Why an Integrated Pest Management (IPM) Plan Is Now Essential
With rodent pressure rising and legislation tightening, farms must adopt a more strategic, proactive approach. This is where Integrated Pest Management (IPM) becomes invaluable.
IPM is not about simply placing bait boxes around key buildings; it’s a comprehensive, environmentally responsible strategy tailored to each individual site. An effective agricultural IPM plan includes:
Prevention First IPM prioritises farm hygiene, proofing and habitat management. By reducing access to food, water and shelter, you make your site far less attractive to rodents. This may include improved waste storage, sealing entry points, vegetation management and feed spill control.
Continuous Monitoring Regular inspections and motion-activated monitoring systems allow early detection of activity before it escalates into a costly infestation.
Targeted, Responsible Treatment If rodenticides are required, IPM ensures they are used ethically, legally and in line with best practice. This becomes even more important under the 2026 rules, where misuse could carry financial and regulatory consequences.
Protection for People, Animals and Your Reputation A robust IPM plan protects:
Public health, by reducing disease risk
Your workforce, through safer working environments
Crops and stored grain, by minimising contamination
Livestock, by limiting disease transfer
Your business operations, by reducing financial loss
Your reputation, by meeting Red Tractor and assurance scheme requirements
In today’s agricultural landscape, reactive rodent control is no longer enough. Farms need a long-term, prevention-led strategy supported by trained professionals.
