I had a neighbor breeding large, noisy, dangerous dogs, working on loud cars, and throwing parties every weekend. I mixed up five gallons of chicken broth, Miracle Grow, etc, and sprayed it on his house, garage, cars, etc. Hardly noticeable. I did this once a week. After a month or two, everything had turned mildew black and stunk like death. A few anonymous tips to the township and the SPCA, and the dogs were gone. I kept spraying. The neighbors moved away within a year.
Why chicken broth?
