Rodent Invasion – Are you prepared?

With much of the Riverina in the grip of a rodent invasion, Wagga Wagga City Council’s Environmental Health team has some tips for the city’s food businesses operators and householders on managing the pests.

There are horror stories about serious infestations affecting farms, businesses and residents in villages, towns and regional centres across New South Wales.

Council’s Manager Environment and Regulatory Services Mark Gardiner said the pests are attracted to homes and food businesses as they can provide shelter, food, water and the warmth they require.

“Common pests such as rats, mice and cockroaches can carry bacteria and viruses, contaminating food and food contact surfaces,” Mr Gardiner said. “For a food business, pest sightings and food contamination due to pests can also result in customer complaints and serious damage to their reputation.

“However, there are actions food business operators, as well as general householders, can take using a sound pest management practice to help reduce the risk of a rodent invasion.

“Preventing the entry of pests into your premises in the first place is the most effective step, increasing your chances against winning the battle.”

The Environmental Health team recommends undertaking regular and detailed inspections of the premise to find all possible entry points and undertaking measures to close those entry points; a mouse only needs an eight-millimetre gap to enter your premises.

Other actions include preventing the harbourage of pests and undertaking eradication measures if signs of pest activity are found in the premises such as sights, sounds, faeces, urine, burrows/nests.

“Our Environmental Health team’s happy to help food business owners with any questions you have about your inspection findings or compliance action,” Mr Gardiner said.

“We can clarify what work needs to be done and the timeframe.”

There is also support available for those affected by the mouse plague through the NSW Government’s Mouse Control Support Package.

MouseAlert is a free resource available to stay informed about or to report mouse activity in your area.
