Moles are active right now and the spring litters of newborns will soon be arriving. This means a lot of tunneling as they search for food.
It is a common misperception they are feeding on beetle larvae or grubs. While this may occur, their main diet is earthworms. So, the presence of mole tunneling does not necessarily mean there is a grub problem in the turf.
A grub infestation in the turf can be verified by digging and seeing if grubs are actually present. However, even if they are, now is not the time to treat as the grubs are too large to be controlled by insecticides. Grubs are best controlled in the fall after the new cycle emerges from the summer breeding season and they are small.
