Natural predators...
I make my own orange oil...good for a lot of things, one being it keeps ants off my kitchen counter.
Before my house burned down, we had an ant problem. Wiping a barrier line of orange oil around the counters kept them away for two or three days.
Sometimes I would play with one...put a ring of orange oil around him and he wouldn't be able to get out of it. If I left him alone like that for a little while, another one would come to keep him company. The second one would stay with the first one for hours, but if I left them over night...the one inside the circle of orange oil would look like he tried to wade out but died trying and the second was was gone.
