I have an empty sandbox out in the back that I've loaded with regular dirt, compost, and manure. I collect leaves and put them on the pile and then go out and find some worms in the spring and summer. We have a garden so there's always a nice amount of worms to dig up. Get a bunch of them, drop them in the sandbox and voila, your own little worm farm.
I can vouch for my little farm, and you won't believe how big the worms get from all the nutrients in the soil. Just watch over it and cover it up before it rains and you've got your own free bait.
