Ants: Adam Had ‘Em

I used the old rhyme by Ogden Nash to draw attention to a problem I have at Casa Oliveria. I have ants surfacing at several different spots around my spacious garden. In the past, I’ve sprinkled ant poison around large nests, with little effect. The ants this year are getting so aggressive that they’ve swarmed my brother when he accidentally stood in the general area of their nest and they’ve helped themselves to the dog’s food whenever we put it outside. Help!

Question: How do you get rid of ants?
