Strange thing, it seems that on mobile at least the drones(ground ants) aren't actually outright aggressive. The flying soldiers are, and will track u through the entire map if u let them. But the ground based ants only follow the flyers. Once u killed the flyers without damaging the ground ants they will crawl towards u..and stop just short of touching. Kind of like the pulmonoscorpius. They do attack if u attack them first or if u touch them but they don't just bite u outright like the flyers do.
