I am fed up of maggot infestations. We've had 3 in the last month or so.
The green bin (food & garden waste) got them in, so I scrubbed it out well but they came back again a couple of weeks later. Now we've got them in the black bin, even though I'm pretty certain I've not put any meat waste in it since it was last emptied. (The bottom of my fridge is full of meat packaging which I don't have space for in the freezer and I daredn't put in the bin as it won't be emptied for another week.)
What can I do to stop them coming back?
