My daughter was staying with her friends out of town for a week. She left a bowl of dog food in her room. I noticed one ant on the wall in the hall upstairs and followed a few others into her room to find a 3" wide band of ants that made a strip out of the window, across the roof the the house, down a drain, across the lawn to the back of the property. On that day I had a war with the ants. I will never forget that day. Ants -1 Dad- 0
