I had a problem with ants in the ferret area recently and found a granular product that you spread around the perimeter of the house, and water in. I can't remember the name of it since I threw out the bag, but I did go to a feed type store so I could talk with someone who would be more knowledgeable than your typical bargain store employee. The bag was less than $10 and I was able to go around the entire outside of my house. I did it right before it was supposed to rain, letting Mother Nature water it in for me. I saw a few stray ants over the next couple of days but haven't seen any since......fingers crossed. Katharine [Posted in FML issue 5326]
