DaisyDo said: Researchers are saying that Parkinson's seems to be triggered by exposure to herbicides, and dry cleaning chemicals. My husband, who now has Parkinson's was exposed both to the Agent Orange herbicide in Vietnam, and the dry cleaning chemicals that leaked into the well water at Camp Lejeune. So, I must caution everyone here about using herbicides. We will never again use them. Many people don't realize how much more toxic they are than insecticides. And it absorbs rapidly through the skin.
And Parkinson's is increasing in prevalence. Wives of two of our close friends also had/have it.

If the CDs stop working, maybe try a colored resin "lifelike" statue of an owl or other bird predator, in the iris bed. Turn or move it a bit every day or so, so it looks "alive".
