I live in Texas . I buy 5000 at a time . We have our chameleons set upstairs it stays about 78 degrees. I have a stand that hold 3 15 gallon fish aquariums with a screened top. I put about 1000 to 1500 in each one. They live about 2 months. I buy the 1/4 inch size because they grow fast. You need to make sure they have food and water at all times or they will die. I use the cricket quencher for their water and a gutload I use for their food. A couple of times I have even managed to breed crickets.
