Grasshopper invasion concerns

Seems like the grasshoppers have gotten out of control this year a problem I have never had before. I had some Seven XLR left over from Timothy mite control and it smoked them. The grasshopper’s literally ate a field completely off only leaving stems before I figured out what was happening. My question is I will be planting new fields in about two weeks my concern is will they chew the new growth fast as it comes up. I heard a local guy has sprayed three times and they make a comeback in a week or two. Any input would be great on chemical’s or strategic planning for dealing with them.
