Council digs deeper to scratch midge dilemma
  • Tuesday 16 November 2010

They’re tiny, relentless and downright irritating!

Midges are renowned for their nuisance around local rivers, canals and creeks and Sunshine Coast Council is upping the ante in the war against these pesky biting insects.

Division 3 Councillor, Keryn Jones said a new measure to eliminate midges would be performed at Currimundi Lake in the coming weeks.

"Council has identified a mud basin opposite Gamban Esplanade that is a hotspot site for midge breeding in Currimundi Lake," she said.

"After consultation with local fisheries and the Department of Environment and Resource Management (DERM) we will be undertaking some earth works to disturb this midge breeding habitat."

Cr Jones said Council had dramatically reduced midge populations around Currimundi Lake in recent years by temporarily raising water levels to a height that was typical prior to upstream development, but that process hadn't been without its pitfalls.

"By temporarily raising the water level in the lake over a number of years we’ve reduced the average number of midges in the area from 1400 per square metre to around 15 per square metre.

"Unfortunately this process has also damaged some banks along the Lake and caused minor erosion.

"This new measure will pin-point a midge breeding hotspot and should reduce numbers of these pests which will make life much more comfortable for nearby residents.

Cr Jones said midges could also be controlled with fogs and sprays but Council was keen to avoid the use of chemicals.

"Those measures are not effective long-term and by not reverting to chemicals there will be minimal impact in and around this local waterway, which is a much better result for our environment."

Council will begin its new midge control works in the coming weeks.
