So quick backstory, I'm planning a29 gallon terrarium housing for ants. The 'back' and short, side walls will have wood blocks affixed to them with tunnels and chambers pre-drilled (using black walnut because... of course I am). There will be hydration holes drilled and I THINK I have the ventilation issues sorted out for the most part BUT...
The rest of the terrarium will be mostly covered in moss with maybe a small, potted 'bonsai' style money tree. Very small deposits of soil in other parts of the tank. Is it enough to encourage them to nest in the pre-set tunnels to keep the dirt too damp for their liking? I just would very much rather not have them nest in an area I haven't plotted out. I know there aren't any guarantees, just looking for tips to encourage them to nest where I choose. \
Camponotus Nova. is the species.
