Did you try pulling up the grass and check for grubs?

Just went out to dig a small square and don't see any. I also did an application for grubs a couple weeks ago.

I dug up another hole and found something this time (it was dark yesterday too). I found little white, soft, oblong things, about 1mm wide and 2-3mm long. They don't crawl or anything. After some quick google image searches they look more like ant eggs than grub eggs (which appear to be rounder). I did also see actual ants where I dug. But they wouldn't kill the lawn would they?

The dead spot doesn't appear to be growing or thinning out more today.

 

Take and post close up pictures of the leaves.

 

is the grass loose or shallow rooted? This looks like insects to me. If you didnt hit for grubs in May, this would need curative insect control, they needed to be control earlier.

If the roots or turf pull up, pull it out, scruff it up and throw some seed down with coverage while you can.

Here's a couple

The hole I dug was about 2 inches thick, so maybe they're a little shallow rooted? I also did an application for grubs in May. The product I use is Jonathan Green Grub & Insect Control which instructs to apply twice, once in the spring and once in summer. Also this area was completely fine on Saturday before the rain...or fine enough for me to not notice when I mowed.

I'm planning on mowing it again today and putting seed down. But I also have no idea if that will fix it or if the problem will come back.

 

That sure looks like fungus.

Do I need to be concerned of it spreading or lasting longer than a couple days? I just put more seed down, anything else I should do? Its my first time seeing fungus.

 

I was on vacation last week and came back to some more spots that look like this. The grass blades turn slimy and are ripped off easily. I think my overseed was too thick and now that area has problems drying out due to lack of sun and constant dew every morning.

What can I do to help it? Is it even considered a fungus?

Sounds like ant eggs. And yes, ant nests can certainly cause bare patches in your lawn. I had a patch like that this year, and it was an ant nest.

Do some testing with a dab of honey and peanut butter. Which one attracts the ants? You'll find out if they want sugar or protein. Sugar ants are surely easier to kill, btw.

Put out some bait traps with the appropriate bait (protein or sugar). It will kill the colony eventually. You might have to refill the bait if it's a big colony. I had a lot of ant issues this year and killed off several colonies. A lot of this bait can be homemade as well if you want to get really hands-on.

Sugar ants are surely easier to kill off, btw.

 

So here's a picture of a small problem spot. This should show what I mean by a slimy look due to being wet too long. In the bottom of the spot, where my finger is covering/pointing, I pulled lightly on the grass to get it off the ground. Otherwise it looks like the top of the spot, where it's flat on the ground. Like mentioned earlier it rips off very easily.

 

That looks like pythium .

After some research I'm coming to the same conclusion. Looks like Scotts Disease Ex is the only thing I can get my hands on that will help. A granular product needs to be watered in, yet water is likely what's causing the problem. :roll: Is dew enough to water it in?
