That is genius! I bet it would work on tomatoes too. For some reason the neighborhood squirrels seem to love the darker tomatoes (can't blame them). I lost 2 Cherokee Purples, most of my Black Cherries, and this morning I came out to a half eaten Carbon. They wont touch the bright red ones - Sweet 100, Matt s Wild Cherry, Amelia, Better Boy, Bella Rosa - all go by unscathed.
I'll have to start saving these up for next year...
