bustergutt, I too have an ant problem. I am using Nippon and a spray called Dethlac. The Dethlac seems ok but you have to keep reapplying as it washes off in the rain. I spray the brickwork around the base of my house up to about 4 inches. I have to say I have noticed a lot more ant nests in the garden and this year they were all over every single pot, even the few herbs that I have. When I emptied the kitchen bin on Monday there was a lone ant crawling on some rubbish. Now I KNOW there isn't just one solitary ant in my house. Problem is it is becoming an obsession with me and I think I see them crawling on the carpet out of the corner of my eye and I find it hard to relax, especially as the nights are drawing in. I have no answer for you but after speaking to colleagues here, they too seem to have a problem. If you can solve this problem I am sure you would make a fortune! I'm from Huntingdon by the way.
