Giant vinegaroons (M. giganteus)

Does anyone here have experience raising these things? Do they require artificial heat sources?

No heat...room temp or even bit cooler is just fine.
I have found them walking around quite comfortably in AZ during 55F nights.

Give them plenty of deep, moist substrate and they'll create their own microclimate.
