At one of the houses I lived in the little blighters used to swarm all
over the kitchen cupboards. I tried everything but no luck. They would
come and go at random. Something to do with the season or the climate
or an ant 'race' (culture) development?. In the jungle I have seen
Marching Ants but you get to hell
out of it, - but quick.

We had a sudden population explosion in the house (though luckily the
living-room, not the kitchen). Last week was graduation week - all week
long the window was black with winged ants and worker ants pushing them
and (presumably) shouting 'fly! fly!'
Hated it, but there was no choice - ant killer. It's very quiet now; I
hope the rest will take the hint and move back out into the garden,
where the green woodpecker is teaching her baby to catch ants!
