Things in my worm farmReader submitted

Hi, HELP - can you please tell me if these are fruit fly larvae?  My hungry bin worm farm seems to be absolutely crawling with them and I do get a lot of fruit flies in there.  Any tips on how to stop them getting in, or at least from breeding so much?  The bins smells okay, but I'm starting to think it's a fruit fly farm, and not a worm farm at all???!  Thanks.
