Hi, Lois – Thank you for contacting UNH Ask Extension’s Infoline regarding which would be better in your garden: a mole or jumping worms. That’s such an intriguing and thoughtful question. As you noted, moles are predators of the jumping worm. Moles also play an important role in the management of soil, grubs, and other insects. Jumping worms, on the other hand, do not have any helpful role in your yard. Based on these considerations, the mole seems the better choice!

Following is a link that includes information about how to control moles and also the benefits of moles. (Specifically, see “Economics of damage and control,” toward the end of the article.)

Information confirming the moles as predators of jumping worms can be found in the following link. (Specifically, see page 6.)
