I am going to order from LLL Reptile for my crickets in bulk since I have a water monitor and tegu that gets them off and on. My question is with getting 1000 crickets what do I keep them in? I know the cricket keepers but is there anything else I can use? The cricket keepers say to only keep 150 or so in each one and they are about $15 a peice. I don't mind buying more but just wondering if something else is a better option?
