Are you trying to put them inside? All bees need are to be outside without something right next to them. Put them on a 2x2 floor tile outside and you should be good. That seems less immersion breaking than devcommands...

Bees do make nests in the walls of home, but they still need access to the outside, Around here, the primary method of treating such an infestation is to seal off all the entrances and exits.

I can tell you that it does work. They find ways to get out, including into the house, but they do go away.
