Mosquito surge likely after heavy rains

A LARGE influx of mosquitoes is expected across the Geelong region this summer following recent heavy rains.

The City of Greater Geelong warned residents to prepare for above-average numbers of mosquitoes, as it rolls out Victoria’s largest mosquito management program.

The council’s planning and development acting director, Geoff Lawler, said there was extensive monitoring and treatment, including the coastal wetlands on the Bellarine Peninsula. It began ground treatments of breeding sites last month, and will attack from the air once warmer weather arrives in the city.

“We also strongly encourage residents to play their part in managing the mosquito population in and around their homes by checking items on their property which hold water,” Mr Lawler said.

Mosquito levels are also monitored by setting traps in residential areas, using Bacillus thuringiensis isralensis and s- Methoprene. These products only affect mosquito larvae. People, other animals, and the general environment are not adversely affected.

Last summer Geelong had a record number of cases of the mosquito-spread Ross River virus. More than 80 cases were reported in the Barwon South West region and the number has continued to rise.

Up till last Sunday 187 cases have been reported this year in the Barwon South West region and 1924 cases statewide.

This is 18 times the number of cases reported in the Barwon South West region last year and 11 times the number of cases state wide.

Victoria’s chief health officer, Professor Charles Guest, warned Victorians to avoid bites this summer and cover up, particularly around dawn and dusk.

He said homes should have insect screens fitted to doors and windows. Residents should wear long, loose-fitting clothing and use insect repellent.
