Moles Questions Answered

Common questions about identification, prevention, and treatment

Call (208) 297-7947

Do moles eat plants?

Quick answerNo.

Moles are insectivores that eat earthworms, grubs, and insects. Plant damage often attributed to moles is usually caused by voles using mole tunnels. Moles may incidentally disturb plant roots while tunneling.

Will killing grubs eliminate moles?

Quick answerGrub control may reduce mole activity but won't eliminate them.

Moles primarily eat earthworms, which are beneficial and impossible to eliminate. Trapping is the most reliable control method.

Are moles beneficial?

Quick answerYes and no.

Moles aerate soil and eat lawn-damaging grubs. However, their tunneling damages lawns and gardens. The trade-off depends on your tolerance for cosmetic lawn damage.
