I've tried breeding crickets for some time, but I never really got the hang of it. A lot of them died in the first days.
After a while, I got them through the first 2 or 3 sheds, but they just kept dying or dissapearing.

So I switched to Shelfordia tartara (spelling? ) or as they are called in holland, Red Runners.
They are red...and they run! Breeding them was just wonderfull! I bought 4 cricketcontainers (aprox 50 per container) and after 1,5 years, they where still thriving. Sadly, they are real escape artists so I got rid of them about a year ago. Even worse...I found one (adult female) last week...alive...So no more Red runners for me! Never!

After the red runner fiasco, I didn't have the guts to breed raoches. But a few months ago, I bought some B. dubia. Wonderfull animals. They take a lot of time to really get going, but when you have a nice colony, they should be excellent!
I have had them for two months now and I guess I've got around 200 to 300 babies. A few more months (5 or 6 or something) and I might start using them as food.
