It’s actually pretty simple of a process and a nice break, to be honest. I can’t wait to put my big colonies down, lol.
What you can do is start by taking the colonies off heat cables or whatever you use, or move them to a colder room. Let them gradually cool down for a few weeks. With Formica and Camponotus, you’ll want wait until the colony has no more cocoons. Pupae cannot survive the winter and will rot or mold. Eggs and larvae are fine to overwinter. Once they’re ready, just pop them in a fridge and enjoy your break.
