Hibernating my first time colony

[Kalous]

I live in an apartment building in Ontario, and I am worried about the hibernation process. My two ant colonies reside on the balcony, because the gf doesn't want them in the apartment, is there any method to keep them alive during winter outside? Or am I going to have to buy some kind of minifridge?

Mini fridge I guess lol. That's what I'm gonna use. Actually it's a wine cooler where you can set the specific temperature.
