Another tip for Foxy Lady......I was watching a cooking programme set in Marocco & they were growing lots of grapes on overhead trellis, then on the ground they stuck a stick with an orange on the end of it, the orange was covered in syrup & all the bugs were attracted to it & they left the grapes overhead alone!
Dont know if this helps at all, but it worked well in Marocco & its enviro friendly too!
