I was watching a thing yesterday on fire ants, their migrations and survival, and how sturdy they are.
Seems certain flies in SA are the answer, as they lay one egg in a fire ant. To make a long story short, the dead fire ants are taken to the ant graveyard, just outside the hill, and when the new flies hatch...antnihilation!
Ain’t Mother Gaia just so sweet to her li’l chillun?
