Shallow-dwelling worms, such as redworms, live primarily in the top twelve inches of soil. These worms do not build permanent burrows, but prefer to randomly burrow throughout the topsoil. When the weather gets colder in the winter, or the soil heats up and dries out in the summer, these worms will move deeper into the soil.
