D.P.S
If you're in their natural range, keeping them outside seems to be the go.
If you can't, then give them periodic access to natural, direct, early morning or mid-arvo sunlight.
Like TrueBlue & others advise, make sure they have access to cool areas 24/7.
Never, ever overheat them :!: .
Cooking them fries their nervous system :!:
Keep them cool 8).
But avoid draughts & sudden temp. fluctuations, or they'll get respiratory infections!
Like GTP'S, treat them delicately, like "wet tissue paper".
