Why buy cocoons instead of worms? Vermicomposting (composting using worms) can be a fantastic hobby and a great way to live more organically and eco-friendly. Worms can cost $40 per pound (1,000 worms) OR MORE. A red wiggler cocoon can have 3-5 worms per cocoon (in perfect conditions)! That means that 1,000 cocoons could realistically yield you as many as 3,000 or more worms! Shipping worms can be tricky. Worms are temperamental and can only handle temperatures from about 40-85 degrees. Cocoons on the other hand can tolerate just about any temperature extreme. Cocoons can go dormant and will not hatch unless conditions are suitable to their needs. The cocoons you will receive have been shipped in burlap bags along with compost that is inoculated with healthy microbes to jump start a new bin.
