What I do is put a piece of banana (a slice will do) on top of the dirt of the potted plant and the flies swarm to it. My baby chams can then just pick off the flies at leisure and it keeps the majority INSIDE the reptarium and not outside.
Veileds like fruit, do he probably will eat the banana and flies. LOL! Be sure you change out the banana every day or other day to insure no other nasties grow on it.
