Double-bagging

What do you do if you’re worried about getting maggots in your wheelie? According to Swindon Borough Council you wrap them up well, twice.

Food waste shouldn’t be left uncovered in the house, as it can attract flies to lay eggs on it before it goes into the bin, so it’s best to place it immediately in the bin, securely and preferably double-wrapped.

Wheelie bin lids, if kept tightly closed, prevent flies from getting at the contents.

why the need for double-wrapping?
