If you have the room, make a compost pile. All the worms you want, although they disappear about late October around here.
Use grass clippings, leaves, anything organic. Add in kitchen waste like eggshells, coffee grounds, fruit rinds, stale or moldy bread, etc.
Add cornmeal, the worms love it. Compost piles don't stink either, you just have to "turn" them over every week or so. (use a pitchfork)
DONT add meat scraps or bones, dog crap or anything like that. Then it will stink, attract critters you don't want and add harmful bacteria to the compost, which can damage any plants you may put the compost around.
