Grasshoppers are a perennial problem, more some years than others. It's something we have to put up with because the ways to control them are not really practical.
1) All the ranchers around us would have to disk all their pastures. That's not going to happen. What would our cattle eat?
2) Everyone would have to use tons of NOLO. It would have to be re-applied every time it rained.
3) Pesticides would also have to be used over a very large area. They don't work well once the grasshoppers get wings.
And more importantly, grasshoppers would move in from other areas to fill in the void left by the dead. The most we can hope for is we have a wet year which reduces their numbers.
Have you ever been bitten by one?
