Oh Crickets! I am on my FIFTH attempt right now... so i'm certainly no super-hero-cricket-raiser... In my experience it's all about the M/F ratio. I typically go to PetSmart (who I have a good relationship with) and ask if I may pick out my own crickets. I stand there and pluck up about 80% females. It takes forever and everyone laughs at me but I honestly don't care. Doing it this way and then basically following the instructions laid out by emandkel has worked OK. I typically can get 2 generations or so and then I have a mass die-off. :shrug: If I have a success this time, I'll let you know.
