Tiny Russian Model I Can't Get Rid Of The Fruit Flies In My Russian Tortoises Cage!?

I can't get rid of the fruit flies in my Russian Tortoises cage!? - tiny russian model

I feed my turtle Russia a mixture of green vegetables every morning, clean the old stuff in the night. Recently I've noticed that when I go to feed or remove the green, there is a swarm of fruit flies in the cage. Small creatures are, there probably will not be able to pick them up and steal seconds to open the lid - All proposals for always going to be? The turtle does not seem to bother you all ... But I am!
Thank you!
