I had tried all the things you can get in the stores to get rid of these ants. I found this website and used the Borax and powered sugar, I put it in a ziplock sandwich bag. (of course I left it open) I placed the bag on the counter at night the next day there was so many all over the place but I decided not to squish them and see what would happen. The next day ants were dead in the dishwasher and none on the counter.
Its been three days and maybe I see one or two ants. They were in the dishwasher and always all over the counter. They are gone!!
I do rinse my dishes, and try not to leave food out. These ants are real invaders they find a single crumb. But not any more, HaHa!!
Try it definitely works.
