I recenlty picked up the hybrid nest designed for the large camponotous ants. In one of his videos, AC suggests filling part of the nest with soil. That gave me an idea:
what if I fill the entire nest, except for a small portion right in the front, with soil, so that the nest essentially becomes correctly sized for a founding colony, and as they grow, they can excavate soil as they like and dig their own nest.
Would that be a bad idea?
