I hope this is considered within the scope of this forum. If not, I apologize.

Each year I put out Halloween pumpkins on my open front porch, and each year rats and/or squirrels chew on the them. It's gross to look at and of course, it eventually spoils the pumpkin. I have tried amateur discouragement solutions like sprinkling hot pepper around them and spraying them with hairspray. These haven't been effective.

I like having decorative pumpkins outside. Is there any way I can keep the rodents from nibbling on them? BTW, when I say "cut" pumpkins in the subject line, I mean that they are not on the vine, not that they are carved.

This is in the San Francisco Bay area of California, though I don't see how that would affect the answer :-)
