While I assume that most here have already put their colony's into hibernation, some of mine have stubborn stragglers that still insist on strolling around in their outworld.
I've tried leaving a window open in my 'ant room' hoping the cold overnight temperatures would get them to re-enter their respective nests but when I check in the morning there are still outworld stragglers. I've removed all food/liquids from the outworlds more than a week ago.
Any other suggestions / methods I could try?
I'm really hoping to get them in the fridge this coming weekend.
