G'day all.
I have a few small colonies (of about 5-8 workers) and the water cotton in their test tubes is becoming quite moldy. These are my first queens and I would be devastated if they were killed by mold. I have tried taping the new test tube to the old one and coving it and shining light into the old one but the queen didn't want to leave. Please help out a newbie.
Cheers
