heres a basic care sheet.
keep the adults in a large storage container with a fair bit of height so they cant jump out. crickets need a lot of ventalation so if you need a lid make sure most of it consists of aluminium fly sreen. stack about half the container with egg cartons for hides as these are very neccesery. i use carrot, zuchini and cucumber sliced as a water source. make sure you put new ones in every 2nd day at least. they also eat lettuce leaves and dry dog food. in summer you shouldnt need any heat but if you are breeding them in winter they need to be kept warm (around 28C). you will also need a small container filled with peat moss for the female crickets to lay their eggs in. females are the ones with a long spike looking thing coming out of their abdomens. you should here a continous corous of chirping which is like theyre mating call. after a day or so you should observe the females in their laying containers. after a day or two of this remove the container and put in a warm place that is a constant 30Cish. they will hatch after 10 days or so.
Hopefully this will help you out a bit. any more questions feel free to ask.
Cheers
