1.5 Do queen ants ever leave their nests?
She never leaves her nest unless there is an emergency like a
disaster or the colony wants to move to a better or larger place.
Most of the time, it is to find a more favorable home (current
one too hot, too cool, too wet, too small, mold, etc.). --Ant and
Mr. Ant
However, some multiple queen colonies (e.g., Formica polyctena)
build daughter nests as a part of the colony with brood and
queens. Queens leave the nest together with some workers and some
broods to find a place to build new colonies. --Jinei
