I came outside early yesterday morning, and found one ripe melon, partially hollowed out, left to rot. It was too big for the suspected raccoon to carry away, so he snacked and left. He had also hollowed out a fairly large eggplant, still hanging on the plant. Fairly large teeth marks.

This morning, same thing. Another melon hollowed out, and left to rot. "Shake Away" small critter granules has not worked. My garden is organic, so I don't want to use pesticides.
Will sprinking black and red pepper flakes all over the melons work? How about spraying the melons with Tabasco pepper sauce? Any suggestions are welcome. I am tempted to patrol the garden all night with a shotgun, but it might only scare my neighbors.
