ITV Expert Warns of Rat Invasion with Simple 50p Home Test
A pest control expert has issued a stark warning that rats may be infiltrating UK homes unnoticed, as the country faces a potential plague driven by extreme weather conditions. Vicki Hall, appearing on ITV's This Morning, demonstrated a straightforward method using a 50p coin to assess whether properties are vulnerable to rodent entry.
Surge in Rodent Activity Linked to Climate and Weather
Rentokil Pest Control has reported a 10% year-on-year increase in confirmed rodent activity, with significant regional spikes. Northern Ireland saw the largest rise at 26%, followed by Yorkshire at 20% and north-west England at 19%. Other areas, including the West Midlands and Scotland, also experienced double-digit increases. Experts attribute this trend to longer-term climate patterns, noting that 2025 was the UK's warmest year on record, which can extend rat breeding seasons and boost populations.
The persistent rain in early 2026 has exacerbated the situation by flooding burrow networks, displacing rats and forcing them to seek shelter in homes. Paul Blackhurst from Rentokil explained that while rats are adept swimmers, prolonged submersion drives them to higher, drier ground, increasing infestation risks.
How the 50p Test Works
Ms Hall highlighted that rats can squeeze through openings as small as a 50p coin due to their ability to collapse their skulls. She advised homeowners to inspect their properties thoroughly, checking around pipework and perimeter gaps. "If the head can get through, the rest of the body often follows," she said, urging vigilance to prevent entry points.
Preventative Measures and Professional Advice
To mitigate the risk, property owners are encouraged to take proactive steps after heavy rain or flooding. Key recommendations include:
- Clearing debris promptly to eliminate hiding spots for rats.
- Sealing potential entry points by inspecting walls and foundations for gaps.
- Removing food sources by using sturdy, lidded bins placed away from building walls.
Mr Blackhurst emphasised that early prevention and professional support are crucial. "Simple steps like proofing entry points and managing waste can make a significant difference," he said, adding that pest control experts are available for safe and effective solutions if problems escalate.
With wet weather continuing to push rats into properties, especially in northern regions, experts stress the importance of regular checks and swift action to protect homes from infestations.
