I have a colony of Novomessor cockerelli that I bought last year with 1 queen and 5 workers. The colony made it up to about 15 workers, but then almost all of them died from December-April, and I thought the colony wasn't going to survive. But over the summer, they did amazing! Now there are about 100 workers.
I am wondering if I should do anything differently this winter-- last winter I took off their heat, and kept them at room temp. (60-70 degrees).
This winter, should I keep them heated the whole time? Is it normal to loose a lot of ants in winter?
I am also open to advice about how to keep the population stable-- I don't actually want a much bigger colony to care for, and would prefer not to have another huge population explosion next summer.
Thank you!!
