How do I control flies (not house flies, but like fruit flies) in my compost bin. They swarm when I open it to add material.

It is not harmful to have flies in your compost since their maggots actually consume much of the fresh organic matter that you add to the pile and thus provide food material for the microbes that produce your finished compost. They can be a nuisance to humans who interact with the compost pile, so the easiest way to control their population is to have a ready source of straw, dry leaves or even shredded paper to cover the fresh kitchen scraps when you add them to the pile. This not only denies access to the flies, it also balances the carbon:nitrogen ratio of your pile and helps to produce a better quality compost. LS
