I cannot believe that the squirrels are gone!

My mother has had squirrel problems for years. Lately, it has been horrible, driving my mom (age 90) crazy. I was skeptical, but I purchased [The Guardian] anyway and so far the squirrels left. I cannot believe that the squirrels are gone! The first day, she heard a little noise. The second day, there was a lot of noise, so we thought we made the wrong decision. After the second day, there has been no squirrel activity. I will tell everyone I know any chance I get. I'm serious. I'm telling everyone I know about the success.
