As we move further into 2026, pest activity across the UK continues to evolve, influenced by seasonal patterns, regulatory changes, and wider environmental trends. Whether you manage a home, a warehouse, a restaurant, or a commercial property, preparing for common and emerging pest threats is essential to protect health, compliance, and reputation.
Here’s what’s trending right now and what to watch out for with insights that matter to both domestic and business environments.
Rats and Rodents | Still the Number One Problem
One of the most consistent trends heading into 2026 is a rise in rodent activity nationwide. Pest professionals report increased levels of rats in every region of the UK, including urban and rural areas alike, from the Northeast and West Midlands to the South East and London. Mice are also seeing a notable increase, especially in buildings with easy access to food or unmanaged entry points.
Why this matters:
Rats and mice are opportunistic. As temperatures fluctuate and food becomes harder to find in the wild, they seek warmth and consistent sources of nourishment in buildings. Without early intervention, a small rodent problem can quickly escalate into a widespread infestation, causing damage to wiring, packaging, insulation, and posing serious health risks.
Action tip:
Regularly inspect potential entry points (gaps around pipes, vents, doorways) and consider proofing measures like Ratflaps, professional exclusion work, and routine monitoring
Insects and Flying Pests | Seasonal Shifts Continue
Although warmer weather drives most insect activity, seasonal transitions in 2026 still see certain insects lingering or adapting:
– Cluster flies continue to overwinter in roof spaces and warm internal voids.
– Stored product pests and tiny flies can remain active in heated interiors and food storage areas well into winter.
BPCA technical advice highlights the ongoing importance of species identification for effective control strategies, especially for smaller flies that may be overlooked.
Why this matters:
Even in cooler months, insects can affect food hygiene, customer perception, and workplace cleanliness — particularly in hospitality, retail, and storage environments.
Cockroach Reports on the Rise
BPCA member reports and industry news indicate an increase in cockroach sightings, from residential kitchens to care homes and food handling sites. These pests thrive in warm, undisturbed spaces and can quickly spread through buildings, posing contamination risks and damaging reputations in commercial settings.
Tip: Early detection through regular inspections and professional monitoring is key, especially in environments with continuous food preparation or storage.
Changing Regulations & Pest Control Standards
2026 isn’t just about pests, it’s also about how we control them. New industry requirements related to the Campaign for Responsible Rodenticide Use (CRRU) are coming into effect this year, calling for:
- Mandatory use of CRRU‑approved certification for professionals purchasing rodenticides
- Annual CPD to maintain compliance
- Emphasis on Integrated Pest Management (IPM) practices
- Rodenticide use only as a last resort after proofing and habitat management are considered
These changes underline a broader industry shift towards safer, more sustainable pest management that protects people, property, and the environment.
What this means for property owners:
Always choose pest control providers who are trained, supported by recognised trade bodies, and compliant with the latest licensing and certification standards.
Emerging Biosecurity Concerns
While not currently headline news, public health articles have highlighted issues such as Hantavirus risk linked to rodent activity and the role pest control plays in mitigating spread. A recent BPCA public health feature highlighted the importance of professional pest management in helping prevent disease spread associated with wild rodents.
Practical takeaway:
Rodent infestations aren’t just a nuisance, they can have direct implications for health and safety, especially in homes with children and pets or commercial premises where food is handled.
