Lawn grubs are a common pest that can cause damage to lawns by feeding on grass roots. Fortunately, there are several animals that may eat lawn grubs, including skunks, raccoons, opossums, moles, and certain birds. Skunks are notorious for digging up lawns to feed on grubs, while raccoons and opossums may also feast on these pests. Moles primarily feed on earthworms, but may also eat lawn grubs, and certain birds such as starlings and grackles may also feed on them. While these animals may help control the population of lawn grubs, they may also cause damage to lawns in the process, so it's important to balance pest control with responsible lawn management practices.
