You can also contact the Extension ofc. in your Texas county. They will have the best information for that particular area. At the top of this page, there's a search box on the right side. Type in grasshoppers and you will get a list of threads where grasshoppers are mentioned. there may be some good information there also. I had posted to one thread about "attracting beneficial birds" that an rancher in the hill country swears by flour! He said that when you see the tiny white nymphs fly up when you're walking through the grass or field in early spring, it's time to spread flour. You can read it in that thread.
