Holes in lawn #815124

Asked October 24, 2022, 5:24 PM EDT

This fall I have some holes in my lawn that look like something searching for grubs maybe. I’ve lifted some spots and don’t see any larvae, but not sure. Any suggestions? If grubs, when is the best time to treat? Pictures below.

Hi there.
From your pictures, I'm think that you have some kind of rodent issue. It could be squirrels looking to bury nuts but it is probabaly a skunk or a racoon looking for grubs. Here is a site that has great pictures with which to compare.

Your images also show some dead grass which is a good indicator for grubs. Lawns are the perfect environment for grubs if they are moist with rich soil. One of the best ways to control them is to not over water your lawn during egg-laying time (June-July). The idea is to deny the eggs the moisture that they need. Two other methods are the use or Parasitic nematodes or a chemical pesticide (apply from late May to early August). Please follow the label when using chemical for your safety and effectiveness.
I'm including two links that go into much greater depth of discussion.
