At the council briefing a week earlier, cityhealth services co-ordinator Nicholas Warren said the committee was waiting for approval to trial a new chemical, methoprene, at Lake Goollelal.
�It�s supposed to be a pretty good chemical, more specific to the midge and mosquitoes,� he said.
�The decision was made to test it in Goollelal because of the size of the lake � the amount that we need is smaller.�
Mr Warren said part of their budget each year went towards research such as this trial, and this chemical had been successful in targeting mosquitoes so they hoped for similar results on midges.
The report to the council said residents on the north-eastern side of Lake Joondalup �suffered a plague of midge that was unprecedented� in 1998.
As a result, the cities of Joondalup and Wanneroo formed a steering committee with the State Government and added Lake Goollelal to the management agreement in 2010.
