My Bumble Bee Walking Toads stopped eating

[Bumbleluv]

I was beginning to get worried because my toads stopped eating small crickets. They actually started avoiding them so I took the crickets out of the tank. Finally the Vivarium received pinhead crickets and fruit flies. I didnt think they would ever stop eating. I was thinking about trying the recipe on this site for fruit fly cultures. Is it really as easy as it sounds.

I would assume so, though I use Josh's medium for my flies. I do make my own medium for wax worms though.
