You shouldn't put your own enjoyment before your ants' well being. They usually hibernate in winter, and they probably need it just like any other ant.
@Anthony. Think about it. In the winter, temps in MY HOUSE are not going to drop below freezing. I'm going to be combating the cold and the ants will probably come out more. In the summer my ants hate the heat and I need to hibernate them then, unlike others over the winter from what I've gathered. Lol they're winter ants because they like the cold . but I'm sure they still don't come out when there's snow on the ground. But they will in my house and ill get to enjoy them.
I would agree, on the most part. In my area, they are active all winter long. It varies from area to area, so if you see foragers during peak of winter cold, no need for hibernation (not estavation, that is something all P. Imparis do), no need to hibernate. Otherwise, let them chill
