I was hoping my Pheidole megacephala colony would stay in the test tube, but they moved under a small rock. The entire formicarium is really dry (literally bone dry, the dirt is literally like dust). Only wet area is the test tube. Which I'm surprised they moved to such a dry area, seeing that they are more of a tropical species and not so much a dry climate species. The formicarium is just a small plastic aquarium, and it works well enough. Except at one point my colony size shrunk a lot, so I got more ants and alate brood from a nearby colony and it brought a bunch of dirt with them. But, I was hoping because of how dry the dirt is, they would stay in the test tube...but nope...they decided to move into the bone dry dirt.
Is there a way I can move the queen into the test tube, and have her not get out? So only the soldiers and workers can get in/out of it? I have seen this done, but not sure how to go about making something like that or what materials to use. I'm sure it is simple, but no idea what to use for something like that.
