@ Darkness: but until there are enough minor workers it is a risk ?
So you keep them ? do you have a diary of it i would like to read more about them. Thanks.
Hm, I have a diary, but im also german like the summiter. And unfortunataly my diary does not include any pictures.
was the PTFE GP1 not enough (or what did you used?)
I know that you have not wrote this question to me, but if you and the summiter do not mind, I will give also one solution I have practised.
This variant is very good to hold the ants Back from escaping and running over your floor. I practised this procedure with my colonie of Pheidole pallidula, too.
You need for this a bowl, which is longer and wider than your Formicarium. It should not be too high, its enogh if it is 10 cm.
After you have arranged such a bowl, you can fill it up with water that the ants can perhaps escape from your Formicarium, but they can not cross the water, so they have to go back.
