Hi rodney hanson Sorry to hear about your mole problem. They could be eating earthworms. Any grubs in your soil are likely very far down from the soil surface. The proper time to put down GrubEx is in late spring to control the next round of grubs that will hatch from eggs laid by beetles in late summer.
Moles can be trapped or you could try a treatment that many folks have had good luck with: TomCat. You can find this at your local retailer. Set the bait or trap on active mole tunnels. You can find them by pressing down various tunnels in your lawn and then checking back in 24 hours to see which ones have been raised back up… these are the active tunnels.
Good luck. Moore The best time to apply GrubEX is late spring as it primarily protects from the next round of grubs that will show up in summer. I put mine down in mid May. Snow or rain after application is not a problem. In fact, GrubEX should be watered after spreading. I live in northeast Kansas.

They typically have a life cycle: late spring mature grubs pupate and turn into beetles during late spring to early summer. These adult beetles lay eggs during late summer that hatch into grubs. These grubs primarily feed on grass roots during fall, they go deep into the soil during winter and travel back to the root zone during warm spring weather.
They feed on roots to a lesser degree in spring as they get ready to shift to the pupae stage no feeding takes place. There are two types of grub controls. One application protects for the season. It is hard to kill mature grubs in spring even with the Hour products.
In any case, the grub controls typically do not kill the earthworms. There are a range of mole baits, traps and controls from TomCat. I believe I have skunks that have rutted or damaged my lawn.

Hi Michael This is a likely sign of grubs as skunks, raccoons, armadillos in the south and crows will tear up a lawn looking for grubs and earthworms. There are two types of grub controls: The most effective is the type that is applied once in late spring to mid summer like GrubEX to prevent grubs from becoming a problem; OR one that is designed for larger grubs after they are present.
