Hello, just over a month ago I caught two tetramorium queens, and have housed both in test tube setups since. One currently has about 15 workers and generous brood, and is well on her way to found a strong colony. I have fed her colony multiple times now and try not to disturb them. The other queen I had mostly given up on, as although she produced brood, it was sparse and she never shed her wings. Today I checked up on her and found 3 nanitics to my surprise, and a slowly growing pile of brood. Unfortunately, I don’t have the time nor equipment to raise two colonies. I am based in southern Ontario (Canada) and with fall fast approaching, I don’t know how to safely release this new colony, especially with temperatures beginning to drop.
On the topic of fall, I am worried about the colony I intend to keep as winter approaches. My house is old and the insulation is poor, and in the winter nighttime temperatures can reach 13 ish degrees Celsius. During the day with heating it probably reaches 21. What will happen to my ants in these lower temperatures + fluctuations? I don’t have a mini fridge so I don’t think I can properly set them up for diapause, but even with a heating mat I’m afraid their outworld will be too cold. Any advice is welcome, thank you!
