Ugh. We have crazy squirrels up here, too - I have had exactly the same experience with jack-o-lanterns. Last year I built a very large wooden frame around my tomato plants, covered it in chicken wire, and then buried the bottom in rocks. That seemed to keep them out, although my tomatoes didn't do well last year, so maybe they just went looking for greener pastures. They also regularly eat my sunflowers and sweet peppers, though hot peppers and eggplants they seem to leave alone after the first nibble or two, and I've never had one that ate beans or peas. (I've never had one that ate lettuce either, but I wouldn't put it past the cheeky bastards!) They also will dig in your outdoor pots and in any freshly disturbed soil just to see what's in there, so after planting anything from seed I cover the ground with chicken wire until the soil settles.Â

I have tried installing a birdbath, but I think that thing about them eating stuff for the water is just an internet rumor, because they will literally sit on the side of the birdbath eating a tomato. I've also tried cayenne powder, which didn't seem to help unless I put it directly on the fruit, and then only after they'd checked two or three, and only until it rained. I've tried covering the tomatoes in nylons as well, but the f%#!-ing things pull the fruits off the stems trying to get at them and then leave them hanging in the stocking all chewed up and gross. Berry baskets...interesting idea!

I try to keep in mind that squirrels are a species that routinely overpopulate their habitat (sound like any other species we know?) and regularly die from food shortage, so they're not doing it just to mess with me. But sometimes it's hard.
