At this time of the year at nights it already is about 2°C in countries like Croatia in which those ants live. If you bought your ants from antstore you probably even got some from Croatia, they are one of the most common ants there.
When I was to Croatia at this time of a year at 2010 they were still active when other ants like Plagiolepis couldn´t be found anymore.
In the winter Messor digg deep in the ground and even in spring there are nearly no chambers to 40cm in the ground.
I don´t know how deep they live at that time.
Anyhow 13-15°C is too much in my eyes, I think they would even countiniue to lay eggs at that temperatures.
I will hibernate my Messor capitatus at about 2-3°C. I don´t know how long probably about a month or two.
By the way my Messor capitatus still lay eggs and raise a very big larvae...
