You can provide some heat. I keep my babies in my insect room which is around 78 without additional heat, however the lights provide a bit extra heat for them. You should also get a tub for them and keep them in there. You can house them together until they are eating 1/4" crickets. Then move them to a screen cage. If you put them in a screen cage now and feed them pinheads or fruit flies you will have a lot of feeders escaping.
