The other posters had good points, but forgot to mention heat. I have found that crix need temps between 85 and 100 to do well. If I keep them in the house(78-82), I need to provide a low wattage light bulb, hung just below the lip of my container. It seems to keep things warm and dry. I buy 1000-2000 crix at a time and I’m sure you have a smaller container than me. The 4 things I have found that crickets really need to have are: ventilation, heat, mold free moisture, and dry food/vitamins.
You may want to place your small crix container on a computer monitor, or a TV that’s on most of the time. Near your water heater is also a good source of heat. The heat source should be available at all times. You have to give them fresh potato/carrot/apple every day for moisture. If you lightly mist the side of the cage, they will drink the droplets, but try to keep the substrate dry as possible, this could be done two times a day. It may take some trial and error, I think crix are harder to care for than leopard geckos, but it gives you a sense of satisfaction when things go right. So don’t give up, and remember that crix like warmer temps that people do. Good luck!
