Some species and even different colonies can react differently to stimuli. I've had colonies that don't mind if I shine a flashlight on them to try and get them to move, other times they hate it and move immediately. I'm not entirely sure what setup you have, but if you have access to them, try and blow on them with a straw to irritate them and encourge them to move. ANTdrew recommended I do that a while ago, and it definitely helped move the workers... If you can't do that, I would say just move necessary resouces (food/water) to whatever you are trying to move them into, keep the moving area dark, and continue to make the current nest bright. Other than that, just try to be patient with them, they can be stubborn. You could resort to dumping them if you really wanted to, not sure how imperative the move is, but it's an option. Good luck!
