¨Grasshoppers are attracted to ultraviolet light. That's why the insects are often found swarming glowing bulbs of white light. If residents want to do something about the bugs, they can switch out the lighting around their homes with amber-colored lights."
Maybe in the night put a bright ultraviolet light in the fields - with a strong fan behind it to suck´um in - and then process´em into a fishmeal product to market.
I don't think that light was a problem.
I HAVE read about those fans, though. IF you have a way to do this, insect protein is much better than red meat for us. Maybe you could save some dehydrated grasshoppers for yourself. They are delicious when fried, do NOT EVER boil them.
If you prefer, then absolutely, all the other uses seem viable. As well as the other solutions suggested. I doubt any good chemical poison has been found to control any insect population explosion, though. Locusts have been with us for as long as we know, they have "attacked" fields of grass in past centuries.
