Do biosolids breed flies?
Flies have been associated with man wherever settlement has occurred, with the first housefly having been recorded inAustralia in 1849. There are several fly species which prefer to breed in moist organic matter such as, animal manure, kitchen refuse, lawn clippings and rotten vegetable matter. Biosolids, being a moist organic product, have at times supported fly breeding, but this has only ever been found in stockpiled (not spread) biosolids. For most fly species, breeding occurs during the warmer drier months of the year, which for south western part of Western Australia typically occurs from October through to May. To reduce the potential of fly breeding in biosolids, the Water Corporation commissioned an independent research consultancy in March 2000. The entomologists continue to investigate and make recommendations to the Water Corporation to assist with ongoing improvements to minimise the potential of fly breeding in biosolids. If fly breeding is detected the Water Corporation
