They just might have their own little farm back there! LOL.
My neighbor told me about a product called "Bitter Apple" spray. Found it on Amazon and at the pet store. I used it on my little pumpkins and squash last year to keep the squirrels from eating them as they come up. It worked!!! Until...
I agree...some sort of squash. Last summer I had a whole pumpkin patch near the run that I didn't plant but I'm sure the squirrels did! A neighbor or two feed them so I'm pretty sure that's what happened. Anyway, the grand-kids had 17 pumpkins for Halloween.
