Probably the reason yes. If you cover it up they probably move. Also keep the ytong moist.
Thx and the temperature must be higher or lower than the room?
Everything is covered up and moist but there is still no movement
Just wait and see, they will move, my camponotus herculeanus stayed for a week in the tube until they moved to the y-tong.
How much of the ytong is moist?
It could take a few days before they move. Did we already said you need patient. ;)
