Ashley, a refuse worker in south-east England, is known to fans on social media as the No1 Binman.
He said maggots and flies were attracted to food left in general waste bins as they tended to be collected less often.
Recommending taking your food recycling bin out every week, he said lining a food caddy meant food waste was less likely to get congealed and sticky.
He said: “If you leave waste for a couple of days, it sticks to the bottom. Then you’re the one having to scoop it out. Most councils allow you to use newspaper at the bottom of your food recycling.”
Ashley said biodegradable bags could also help, adding that food recycling was for solids only, not for milk or sauces.
