Somewhere around the first 35 degree week, every general waste bin in the country begins its transformation. The smell is chemistry, the maggots are biology, and both are preventable with tactics that take less effort than holding your breath at the kerb until March.
The problem is food waste plus heat plus time. Meat scraps and prawn shells in a 40 degree bin are compost in fast forward, and blowflies can find a bin within minutes of the lid opening; their eggs become maggots inside a day in hot weather. In councils where general waste is collected weekly the window is survivable, and where FOGO systems have moved general waste to fortnightly, bin management stops being optional.
Everything that works starts with the same idea: the smell is the food waste, so contain it or divert it.
Position and habits do the rest. Keep the bin in shade if you have any; the temperature difference between a shaded bin and one on a west facing driveway is enormous. Keep the lid fully closed, since a propped lid is an open invitation to flies (and, in some suburbs, cockatoos and possums with opinions). Put the bin out every single collection, even a quarter full; skipping a summer week to fill it is the false economy that produces the fortnight bin.
A few preventatives genuinely help: a layer of newspaper or cardboard on the bin floor absorbs liquids, a handful of bicarb knocks down acid smells, and a splash of vinegar or eucalyptus oil around the lid discourages flies.
If eggs got in anyway, do not tip the bin out in horror. After the next collection empties the bin, the fix is a kettle: boiling water kills maggots on contact, then a scrub with vinegar or disinfectant, a hose out, and leave the bin open in the sun to dry completely. A dry bin is a bin flies do not lay in. Many areas also have mobile bin cleaning services that do a hot pressure wash at the kerb for a few dollars a bin, timed after collection day, which is the zero effort version.
Persistent maggots usually mean a routine problem rather than bad luck: unwrapped meat going in early in the week. The freezer habit ends it permanently.
Boiling water over them kills them instantly. If the bin is full, pour it in anyway and let collection empty everything, then scrub with vinegar or disinfectant, rinse, and dry the bin open in the sun before using it again.
In summer, no. A quarter full bin of week old food waste smells worse after a second week than a full fresh bin ever does. Put it out every collection; the truck does not care how full it is.
Bicarb on the bin floor, a newspaper or cardboard liner for liquids, and vinegar or eucalyptus around the lid all help. But the real fix is upstream: freeze meat and seafood scraps until the night before collection, and use the FOGO bin for food if you have one.
