There's a new cricket species being offered out there commercially, Gryllus assimilis, the Jamaican field cricket. This species is great for home breeding. I, like many others, have had a hard time trying to breed crickets on a regular basis. This species is very easy to breed. They just don't seem to die. lol With the cricket virus going around I guess a new species was the answer for many cricket farms. Really though you can find this species online or in my case at your local pet store. They get bigger, are way more productive, hard to kill, and make very little noise. I use a different method than most for breeding crickets. I live in the desert where it's very dry and need a large substrate mass to stay moist for any length of time.
