I read (I think in one of Peter Capstick’s books) about ants in Africa which will gather in their hundreds on a sleeping person and upon a pheromone signal, all bite/sting at once. The assault puts the victim into shock and the ants feed at their leisure. He related a tale of a woman who placed her baby under a tree while she foraged. When she returned the child had been reduced to nearly a skeleton. Ugghh!
When I lived in the Philippines as a kid, I had a nest out in front of my house. We did a lot of shell-diving, but it was always a problem trying to get the darn animal out of the shell completely. There was always some piece that would stay and stink.
That is, until my friend suggested I drop the freshly caught shells on top of that nest. Those ants would scour the inside of the shell so completely they were clean as a whistle.
Being kids, we would put lizards, frogs and bugs on them, and the ants would leave a little lizard skeleton or hollow bug carapace in no time at all. They did that very well.
