We had an ant problem. It was bad. Really bad. Every morning, no matter how well you cleaned the sink, my sink had ants crawling around it looking for scraps of my delicious food. I sprayed behind the backsplash and at the baseboards. I tried wiping and cleaning. They were taking over. I finally bought these liquid baits at Lowes. They came in a 6 pack. You cut a piece off the bottom and leave them around. They are WONDERFUL! The ants go in and die or carry it back to the nest. I have them hidden behind my toaster, canisters, and knife block. I see no ants around the other areas. They are still streaming to the baits, but do not venture to other areas of my kitchen. Hopefully we will get them all soon. You are supposed to get new baits when the liquid in these is gone, until you don't have any ants anymore.
