I have just started ording my crickets online because the price I have been paying at Petco was unbelieveable. For 200 crickets at Petco I can buy 1000 online with shipping, so this will be an easy way to cut costs. Anyway, I'm trying to figure out what else I need to get so I can order a larger quantity of crickets while keeping them alive for as long as I can. I do not want to breed them, just buy them in bulk. Right now I have a 20 gallon high tank (not sure on measurements), screen top, food dishes for them, and water pods for them to drink from. I am also going to use the egg crates that come with the first shipment as a home for them. I have read from other forums that they also need a heating pad underneath the tank? I have also read that if they are smaller then 1/2 an inch you can keep them in an are with a temp between 85-95. If so will I still need an under tank heater? My garage sits at 91 degrees and thats where I am wanting to keep them.
