I hate ants with a passion and this time of year I am on edge all the time waiting for them to swarm. They all seem to know the right day to fly the nest, and all come out together. So I patrol the garden and house armed with ant powder. At the first sign I cover the nest entrance with powder so that any emerging ants get some on them and hopefully expire before they can start new nests.
Problem is, although I hate them I have a certain admiration for them. They are very clever, work as a community for the good of the whole nest and they will still be around long after we have exterminated ourselves.
I once read that, of all the animal species in the world, only ants and humans wage war on their own species.
