NSW Department of Primary Industries (NSW DPI) is reminding farmers to only use registered mice baits and follow all label instructions to minimise impacts on wildlife and domestic animals.
“Mice baits pose a significant risk to farmers, domestic animals, birds and other wildlife if they aren’t used correctly,” NSW DPI’s Director of Invasive Species, John Tracey, said.
“There are currently two rodenticides registered for baiting, bromadiolone for perimeter baiting and zinc phosphide for broadacre baiting.
“Registered baits have met strict requirements and their usage is overseen by the Australian Pesticides and Veterinary Medicines Authority (APVMA) and the NSW Office of Environment and Heritage.
“It’s critical farmers closely read the label and follow all safety and environmental directions, delivery rates, storage and disposal requirements.”
Mr Tracey said the adoption of good management techniques can minimise the impact on non-target species, particularly birds and other wildlife.
“Farmers should closely monitor mice numbers and baits should only be applied where there is high mice activity,”
Mr Tracey said.
“Baits should also be placed late in the afternoon as the peak feeding time for mice is dusk and dawn.”
Mr Tracey said farmers should steer clear of illegal and home made baits.
“Illegal baits have shown to be ineffective in controlling mice and also pose a significant risk to non-target species, the environment, farm animals, pets and children,” he said.
“These baits also contravene pesticide regulations and present a major occupational health and safety risk for farmers who mix these baits at home.
“Poor practices and illegal baits can lead to ‘bait shyness’ meaning mice are less likely to eat the real bait next time.
“Farmers should discuss mice control measures and baiting options with their NSW DPI district agronomist or LHPA ranger.”
Office of Environment and Heritage regulate chemical usage and serious penalties apply for bait misuse.
