Well my neighbor and I both have Armyworms in our bermuda yards. I plan to spray both of our yards this afternoon to try and get rid of them. My neighbor has a bottle of Sevin (22.5% Carbaryl) laying around so I'm going to use it. It says to use 1.5 oz. per gallon to make a 0.26% solution. My questions are, should I step that concentration up a little, or would .26% solution kill them? What time of day/conditions would be most effective? Late afternoon / nighttime / early morning? Should I water the yard after / before / none at all? Please help, these dang things are killing my yard.

They are easy to kill being their soft bodies. Pretty much any insecticide will kill the little bastages

Cut and bag the yard and spray in late afternoon when they are most active...right at dusk.

Armyworms you say? I've seen em before. This picture is from one of our hay fields. They ate 3 1/2 acres overnight. The grass in the picture was knee deep or higher the day before. When they got through, it was 6 inch tall stems. Kill em with Sevin. We use the AG grade and put one quart per 25 gal of water per acre. I think it's 48% Sevin but I am going by memory.

thanks guys. Dang Fur, that's serious damage there. I did the soapy water trick yesterday afternoon, and they came to the surface quickly. Probably 50 or more in a square yard. Then last night, I went out and saw several eating on the grass, like in your picture. Also noticed a bunch of the moths that they turn in to.

Seven will kill them quick. Spray them asap

I believe they make a granular that you can put out as a preventive.

be prepared for a awful smell around your house for a few days if they are as thick as what fur showed.

The only true preventative I know of is acelapryn (sp). Everything else is residual from an insecticide, the chemical above is taken up by the plant

They are normally only active late, early and at night. My brother took the picture that I posted around noon a couple Saturdays ago. It was sunny and around 88-90. I have never seen them that active during sunny weather. We had 50-100 per square FOOT.

The best thing to do for next year, as a preventative is to burn your yard off early in the spring. Their eggs will overwinter on the grass. We had armyworms every year for 3-4 years until we started burning our hay fields. We had not had them since, until this year, when we didn't burn our hay fields. I had them in my yard 2 years in a row and have burned it off every spring since. Burning is great for the bermuda as well.

You ain't wrong. Smelled like a dead animal.

FurFlyin dont tell JWeant to burn something. He will have the whole neighborhood a blazing.

Great, the wife will love that this weekend!

haha, yea this is true!

I imagine it would sound like popcorn if you torched the field right now. I swear when I scouted cotton, you could hear them munching on bolls before you went into the field. They were easy to kill once the plane sprayed the field tho.

Well I sprayed it late yesterday afternoon and did the soapy water test to see if they would come to the surface this afternoon, and there were none to be found! Success!!

Atta boy

We had em on the sod farm a couple times....it was disgusting to have em popping under your feet as you walk. I always wondered how those boogers would do for fish bait.
