how long, if kept in a little container, will crickets stay alive. i just got a new pinktoe spiderling. so, was told to get pinheads. but, i really dont wana store them. and, i live next door to a petco. so will run over there when i have to. but, just wanted to know if i bought a few. how long would they stay alive for. so, maybe i can store a few of them stinkers.
