Dead Lasius Niger colony - why did they die?

So, I got a queen ant from online in early march, in the normal test tube. It had 6 workers already. Over the next month, I kept feeding them mealworms, apple, and peanut butter. The colony seemed to be fine, except that it was growing very slowly - there were only 10 -11ish workers. But then, I checked on my colony today and they were all curled up and were dead. :cry: :( I am not sure why they died, but i have two other queen ants in test tubes, only one of which has laid eggs, but i think i will just replace my colony with that one. I would like to know what could have killed my ants, so I don't do it again by accident.

There has been a sudden heatwave for the last two days, could it be related?

Sounds like they were to cold, what’s the temp in Fahrenheit you keep them in?

Ensure you are feeding them only organic fruits, as most other will have pesticides/herbicides on them. Always rinse thoroughly as well. Also, Did you have direct heat on the tube? If so, you could have inadvertently cooked them if they didn't have a cooler area to go to.
For a small colony like that, I would recommend not feeding anything besides organic apples, a local honey source, and mealworms.
