Have you ever heard of grasshoppers eating a screen? I have large screened in back porch in central Wisconsin. The screen is only 3 years old and grasshoppers have ate about 100 holes in the screen. Do grasshoppers eat one kind of screen vs another. I don't know whether the screen is fiberglass or aluminum all I know is that it is black.
