High-energy mole food comes in the form of grubs, earthworms, beetles and beetle larvae, other insects, snails, and spiders. Moles occasionally eat small amounts of plant parts. Their appetite is almost insatiable, and their favorite food is earthworms.
Controlling white grubs will not eliminate moles as long as there are other food sources available. However, if the infestation is heavy, treating for grubs may significantly reduce the mole's food source and, in turn, result in lower mole activity. Remember that your yard is part of this mole's territory. It may expand its territory to find more food, but this is home. If you have moles already, do not expect grub control to chase these moles away.
Contact your local county Cooperative Extension office for grub and mole control strategies, or see Moles.
