with flies eating almost anything, laying eggs anywhere warm and moist and breeding quicker than rabbits, it can be difficult to PIN POINT where they are coming from.
Where are the flies coming from?
With over 6000 varieties of flies in Australia, we are unlikely to encounter a shortage. These pesky critters feast on a large variety of food sources including organic decaying material such as food scraps and spillages, fruit and vegies, rubbish, carcasses, excrement as well as nectar from flowers. Cutting their food sources is a tricky task when they have so many options.
With flies breeding quicker than rabbits, you really want to keep them out of your food spaces. Flies will lay eggs in almost any warm, moist material that will a supply food for the larvae. The female will lay five or six batches of 75 to 100 eggs during her one-month lifespan. In warm conditions her eggs hatch in 12 to 24 hours.
Attracted to Aromas
Flies have two sensory neurons in their brain that are closely located and interact. One controlling the sense of taste and the other, their sense of smell. These sensory neurons have been identified as the reason flies are attracted to foods smells.
How far will they travel?
Flies will generally roam within a 3-4 km range, with some recorded travelling up to 20 km over 4 days.
If your fabulous food smells are wafting out your doors and your rangehood extractor outlet, off across the precinct, it is safe to say every fly within your neighbourhood, looking for a feed, will be coming to investigate.
