I am going to try that today! There amazingly were not any in my way at the barn this morning but a ton hanging on a nearby tree. I'm not sure why since I deal with it day after day. Hopeful that they are diminishing or a behavioral change. Dawn was part of the lineup in the article for killing but it said 40 or less effective so I didn't try yet. I will now. I sure hope so because it would be way less expensive. I always spend the time and eye strain to make sure they indeed die. Sort of tiring but I wouldn't know for sure. Even bleach didn't do what bug spray does and I was surprised about that last year. Can't wait to see about the Dawn. ThanksA few tablespoons of original Dawn with water in a spray bottle is 100% effective, and safe for plants and animals (unless you are a Joro and have it sprayed on you, then you asphyxiate and die).
