We live in a wooded area, charlie is just a fact of life.:)
We live on the Prairie. We've lived on this property almost 37 years and last year was the first I'd noticed any Charlie at all on our property.
I know it's possible to drag Charlie in from Commercial Nurserys, but it started in the lawn, not in my borders. Do you know if it is airborne? It's the only reasonable explaination I can think of.
