If it works, it works!! We also have problem with little bitty brown ants around the food bowl. I bought some ant traps and set them behind the washer (so the boys could not get to them). I also put their food and water up on the breakfast table (I'm teaching them great things, huh?). The ants have stayed away, but I put their food back on the ground yesterday and by the end of the day they were back. The guys may just have to keep eating on the table, lol. Hmm I may try lizzielou's suggestion and make them stay in a separate room for a few hours while I spray. I'm so worried about accidental poisioning.
