While I was doing my dishes one afternoon, I noticed a trail of ants leading from the window to the sugar container. First I tried to clean up the spilled sugar and eliminate any food left out that might be attracting them. It didn't work, the next day there were still ants everywhere. I asked my mother-in-law for some home remedies and she made few suggestions. After trying to sprinkle dish detergent and then chalk around my home, all I ended up with was a mess. The ants were still there. Finally, we decided it was time to buy a product that was meant to kill pests. We drove to our local Dollar General and looked around. I was concerned about price and also worried about the safety of residue as far as getting on our dishes and into our food. We made sure all of our dishes and food were away from the counter and followed the directions on the bottle. It was easy to use. All you have to do is spray about a foot from the surface wherever ants enter the house. Immediately all the ants died when they came into contact with the spray. This product claims "it keeps on killing with residual action even after you spray, for up to four weeks." So far we have not seen any more ants in our house. I would recommend this product to anyone who has an ant problem.
