I started with Imadocloprid early in the summer when I first saw the moths. It helped some but I was still seeing some signs of worms. I started getting mole cricket as well as the summer went on so I switch to monthly apps of Bifen XTS at .25oz/1000sf. It has definitely controlled the webworms. I'm still seeing some very minor mole cricket activity but no worms. Bifen XTS and Telstar P have the same active ingredient but Bifen XTS is a higher concentration at 25.1% vs. 7.9% for Telstar P. I would do monthly apps at the label rate and you should be able to get rid of them.

Thanks! I'll start a monthly program.

 

I tried everything I could get my hands on and the only thing that really worked was Spinosad. it's actually an organic product, a fermentation/bacteria thing, and really safe. But man, it killed them DEAD. Brand name I used was Captain Jack's Deadbug Brew but there are others. All have you apply 3 oz per gallon of water, at 2 gallons per 1,000 square feet - so a total of 6oz per 1Ksqft. And you want to apply it in the evening, just before dark, to get them while they are feeding.

I applied a second dose a week later, and also put down some imidacloprid and chlorantraniloprile or something like that - whatever the active ingredient in grub ex is. Both of those are not fast kill, but do provide lingering residual protection.

then a few weeks later did one more dose.

 

I got wiped out by them last year. I was ready this year. I hat them with Talstar when they first started to show up.

 

1Fastss -- Same here and I noticed that a lot of my neighbors' lawns seem to have the same problem. I just ordered some Talstar P and plan to put it on this weekend, weather permitting. If it's what I'm looking for and does the trick, I'll apply 3 times a year beginning in March (Louisiana).

I'm finding the army worms under big patches of crabgrass in my St. Aug.

Got a lot to learn here! I'll let you know how the first application works out.
