Are you being driven NUTS (no joke intended) by little furry friends who are nibbling away at your hard won gourds and pumpkins? Then listen up my friend, for I have an answer for you.
Spray Lacquer. Yep. That's it. I buy my pumpkins, wash them off well, dry them in the sun and then spray them from top to bottom with Liquid/Spray Shellac or Laquer from your local hardware store.
I'm not sure why, but it seems to work like a charm. Last year I'd get the odd bite here or there, but for the most part squirrels seemed to detest the taste of it.
If, however, you're trying to salvage indian corn outside, you're on your own. There's no hope for the likes of you.
