How can I effectively manage fruit flies in compost bins?

To effectively manage fruit flies in compost bins, you can cover the compost with a layer of dry leaves or newspaper to reduce odors that attract the flies. Additionally, regularly turning the compost to aerate it and keeping it moist but not too wet can help discourage fruit fly infestations. You can also use a fruit fly trap or insecticidal soap as a last resort if the problem persists.
