Hibernating Millipedes?

Hey guys! Just wondering if it would be necessary to hibernate north American millipedes. I currently have a small colony of Narceus Americanus, and was thinking that maybe I should keep them in the garage for 2-3 months to simulate the temp drop that occurs outdoors. Any knowledge on this topic would be of great help to me as I have been worrying my butt off over the health of my millis.

Thank you all for your time and have a great day

There is no need to do this.

There might not be any need but I have talked with a keeper who keeps mardonius, an African millipede, and he noticed that in the low winter temps they became inactive and seemed to "hibernate".

I don't think any harm would be done, and it might give you, the keeper, a break. But as Crackerpants said they will do fine without this.
