Heat can kill the little ones quickly. So that is one thing that needs to be monitored carefully...
However, to cold and they may not eat nor thrive.
Don't crickets actually chew on animals? Perhaps not the little ones...I would for sure put up those tiny dishes (bottle caps work great) of repashy or panera up. Several ones.
I hope mleedee or Deborah will pop in..
