Looks like a good idea until it was googled:
Crickets are omnivorous scavengers who feed on organic materials, as well as decaying plant material, fungi, and some seedling plants. Crickets eat their own dead when there are no other sources of food available, and exhibit predatorial behavior upon weakened, crippled crickets.
Crickets have relatively powerful jaws, and several species have been known to bite humans.
They can be vicious...lol
