We have newly established Bermuda Sod, almost ready for it's first cutting. Noticed Army worms, had some Diatomaceous Earth and sprinkled all over the yard, suppose to work in 24 hours, but it rained after 3 hours and washed it off. Went to WallyMart and bought 2 bags of Bug-B-Gone, hand dispersed all over yard yesterday morning, yard was very wet and sod couldn't take anymore water, so I did not put anymore water on it. Dew fell again last night, so I was hoping that would be enough water. This morning, I walked all around the yard and no sign of the hungry little critters...GONE!! Thank you, Thank you ORTHO!
