Our specially selected quality compost worms will eat through your kitchen scraps and junk mail quickly, eating up to half their body weight in a single day. Their efficient nature makes them perfect for home composting use. Our worms are sold by the pound, and we recommend 1-2 pounds of worms when starting with a new composting bin. We ship all orders on Monday via USPS Flat Rate service, and we package all our worms in a breathable bag with coir. Please be sure you will be available to receive the package as worms left in the mailbox or outside for an extended period could perish. NOTE: During winter months shipments could be delayed due to cold weather.
