22 Oct Majority of farmers no longer permanent baiting for rats
Just over two-thirds of farmers no longer use rodenticides continuously around farmsteads.
Instead, they employ measures such as tidy yards and rat-proofed buildings, cats or terriers,
traps and shooting, in combination with tactical rodenticide only when needed.
These are common findings of two different studies by Ulster University and the Campaign
for Responsible Rodenticide Use UK, involving 247 farmers in total.
CRRU chairman Dr Alan Buckle urges those farmers who do still employ permanent baiting
to double-check for the one condition under which it’s now allowed – ‘high potential for
reinvasion where other methods have proved insufficient’ – and make sure this is
documented in a control plan.
“Just-in-case permanent baiting is no longer permitted according to rodenticide labels
authorised by HSE and the European Commission,” he says. “Encouragingly, Ulster
University’s study in particular also found strong links between the use of non-poison
controls, or employment of professional pest control contractors, and farmers who
undertook a rodent control training course.”
The findings are being used by CRRU to prioritise what needs highlighting to farmers ahead
of formal review next year of the UK Rodenticide Stewardship Regime by its HSE-led
Government Oversight Group. This body has stated that scrutiny “will focus on the extent of
any behavioural change among those operating in the sector and measurable effects on
residue levels in non-target animals.”
Dr Buckle stresses that, for stewardship to be judged effective, meaningful and lasting
reductions in rodenticide residues carried by non-target wildlife are expected.
“Without widespread best practice by farmers, enabled and supported by training and farm
assurance, this would be an unlikely outcome,” he says.
“The review is looking for evidence of environmentally-sensitive professional rodenticide
use. Otherwise, it could lead to further restrictions on what and where rodenticides can be
used, and by whom.
“Clearly, a significant share of responsibility for good rodenticide practice is in farmers’ own
