I saw some gray moths in my yard earlier this week (last year the moths were white for me) and have already started to treat. However, I've got a few spots where they have torn through in just a couple of days.

From what I have read, they really enjoyed the milder June we had.

Sprinkle poison.

Though it wasn't gray moths I saw, but some kind of moth that was feasting on the grass. You could catch a swarm hovering over the lawn.

Lowe's sells a spray bottle that hooks up to the hose. Two treatments and it shall cure your problems.

My brother and I are treating with different brands. I'll try to remember to let you know if there was a comparable difference.

He went with Ortho because it has Bifen in it. I went with Bayer Advanced because it worked for me last year.

I saw them today also. I got two big bags of the granules and will see if that gets me through the year. Last year I did not treat and my grass is still recovering. I don't have sprinklers though.

Besides seeing moths fly around are there any other signs besides dead grass? I may buy some poison anyways just for good measure.

The tips of blades of grass will look like they have been chewed. My grass just stopped growing. I looked closer and just about each blade was gnawed on.

I used Bacillus thuringinsis or Bt spray on mine and I no longer have issues. I'm sure Bifen works just as well.

If you live near Wabash's new location, they have a dry treatment that worked wonders for us last year.

I had them last year so my neighbors had them as well. I'm the only one that treated. Guess what I just discovered while mowing my yard?

this is what I sprayed last year based off rec from this website. I got to it so late though. So I dont know if it worked. Going to reapply today.

I am going to retreat after the rain. I am using the Black Flag yard spray bottle from lowes and it appears to work. Very few around after first treatment.

Is this the one?

If using Bt, it breaks the egg cycle, which is why you have to do 3 applications. Killing the existing moths won't erridicate them if you can't kill the eggs.

gigem - that is the one. So far so good.

So does regular watering keep these guys away?

I think these moths must be what keep popping up in front of my mower. Didn't realize they were such a big issue.

Ok, thanks! Luckily I don't think I've been infected by them yet, just was wondering if I was safe because of watering or if I still need to keep an eye out for them.

Beneficial nematodes. One of my daughters had tried the chemical solution with so so results last year and I mentioned using BNs based on an article I had read. One treatment knocked them out.

did some research,

Thuricide works well and is organic (not a pesticide). Only $16/pint on Amazon.

I think I have these little f-ers. They look like moths and go into a low swam when I walk to my car in the morning.

What should I look for at ACE?

Did you have to do the 3x within 10 days or just one treatment?
