I have a small enclosed worm farm at the bottom of the garden. Once you get it going make sure you continue feeding regularly with those kitchen scraps. If there's no food you'll soon discover your worms will go elsewhere in search of it!
Also, try and keep it damp, difficult if you are in a warm climate, you'll need to keep hosing it down. Otherwise the worms will go deeper and deeper to avoid the upper dried out parts. And if it dries out completely you won't get any worms.
If you do everything correctly all you'll need to do is scrape the surface and you'll start finding them. Any that are joined together (mating), put those back.
As you can see from mine it's full of soil. This is the end result of a years composting. In a couple of weeks I'll be digging it out right down to ground level and using all that rich soil to feed my house plants and other outside plants. Then I'll start feeding it all over again.
