The Best Worm Books for Kids

By the Bookroo Editors
Updated August 1, 2026

An earthworm has no eyes, no ears, no lungs and no legs, and it still runs the ground under your feet. It breathes through its skin, senses light with cells scattered along its body, grips the tunnel wall with rows of tiny bristles, and eats its way forward — soil in the front, soil out the back, richer than it went in. Charles Darwin spent decades on them and published an entire book about worms the year before he died, and to nearly everyone's surprise it sold faster in its first weeks than On the Origin of Species had. Grown-ups have been rediscovering worms ever since. Six-year-olds never needed convincing: they will pick one up after a rainstorm, name it, and want to know which end is the face.

Drawing from Bookroo's collection of 69 worm books, our editors picked fourteen worth reading more than once: the diary that turned a worm into a household name, the two best backyard nonfiction titles for a garden unit, a Geisel-honored early reader about a friend who comes back with wings, a garden built entirely out of rolled paper, a chapter book about accidentally cornering the fertilizer market, and the 1973 bet that has been grossing out third-graders for half a century. Start with the shortlist, then browse the full collection by age — board books for toddlers who want to dig, picture books for read-alouds and classroom science, and chapter books and early readers for kids reading on their own.
