I have a young colony of crematogaster ceraci and they are in a test tube setup with about 70 workers. When should I hibernate the this year and how thank you for your help

Its good to put them into hibernation when you stop seeing your local ants out and about. Just a general rule...and take them out when you start seeing ants again.

just put them in an unheated area. a shed, garage, or crawlspace works well.
