Quite a few here on the South Coast yesterday afternoon, but nothing
like as many as last year, thankfully.

We've seen a very few but didn't see any last year. I never know if
flying ants and ordinary ants are two different species, or if flying
ants are ants that have developed wings to go and find a new nest site!

Flying ants are ordinary ants, just a different caste. They are the
males and females that get to do a nuptial flight. After they have done
it the males die and the females start a new colony.

I DO know that once you get ants inside an old wall or something of
that sort, you have them forever!

There are poisons that kill whole colonies.
