Here's a short 6 min DIY video on how to build a quality worm composting bin. If done right, it's mouse, rat, possium, and raccoon proof. With luck, it's bear proof, too.
The first shot is of 17 gallons of Garden Gold, worm castings. That's every piece of vegatative food scrap my family threw away for one year. We almost NEVER put the garbage can out to be picked up (the recycle bin goes out all the time, of course).
Not only are you getting value for every piece of food--every strawberry top, every slimy piece of lettuce, every moldy berry, every potatoe peel you buy--but it's staying out of the waste stream.
And you don't feel bad when a bag of salad goes bad in the refigerator, or a pepper, or about all those coffee grounds you grind down the disposal. With worm composting, it's all just garden gold.
