Your hibernation temps should be a little cooler.
Also none of those species hibernate, I don't know about tetramorium though.
Those other species should be put at room temp.
If you put them in the fridge you need to set the fridge to its warmest temperature, but your food would probably spoil.
You can consider buying a wine cooler or mini fridge also.
Yeah I was just puzzled because the salsabeans are acting like they want to bruminate. The fragilis are just booming but the salsabeans are camping out in their little corner. It's weird.
I thought I read that Tetramorium should have a break but someone on Facebook said they don't need to, so I dunno....
If I still had that Pogonomyrmex subdentatus queen I understand room temp is brumination temp for them, but unfortunately she had a fatal accident (sorry) 
I think buying a mini fridge might cause issues lol. I would have to stick them in the crisper drawer of the main fridge... somewhere out of the way....
