Compost

Don't lift the lid!! Seriously though, wrapping peelings in newspaper is supposed to help, or covering peelings etc with grass clippings. Stir the heap regularly.

All the little lifeforms that inhabit your comp heap are helping to break it down and make compost. Could you possibly learn to love them? :-)

They're part of the process, so you can't really get rid of them. If your compost bins are placed away from your home they shouldn't be such a problem.
Collect up your kitchen-scraps in a container with a lid & empty it only once a week.

The flies are attracted by the stagnant smell of rotting compost. If your aireate and turn the heap regularly, not only will this help your compost it will deter the build up of bacteria reducing the stagnant smells, and therfore the fruit flies.

let them be all the little creatures that infest compost heaps help to turn it into good usable compost

They could be friut flies. I always get more flies if I put in fruit particularly citrus fruit remains.

I always keep a bin of leaves next to the compost pile and also some dirt and when I add my scraps (chopped up) I add some leaves and a bit of dirt...dig it in and fork up the pile..too much green without the brown material and you will notice more of a smell..and the flys! .do you have your compost in a sunny site? Perhaps it is too "wet"?

Leave them in - they are helping make you lovely compost.
