I have a mole damaging my front lawn. My neighbor told me that I have grubs and that is the reason for the mole. Advice from over the fence is not always the best advice. It is true that moles do feed on grubs, but it is not true that just because you have moles you have grubs.
Moles forage through the lawn in search of food.
They eat all types of soil inhabiting insects including earthworms. The best method of combating a mole is with a trap. Mole traps are set in the longer, straighter tunnels running through the lawn. They are kill type traps and are highly effective if set properly. Grubs on the other hand feed on the roots of the lawn killing it in late summer.
