Grasshoppers are long-lived insects, generally lasting until the onset of cold weather, but they are homebodies, usually not moving more than a few miles from where they hatched, according to Texas AgriLife Extension Service entomologists.

If you’ve got grasshopper problems now, you’re probably going to continue to have them until this fall, said a Texas AgriLife Extension Service entomologist.
Grasshoppers are long-lived; they’re with us most of the summer, and growers are still battling them, said Dr. Allen Knutson, AgriLife Extension entomologist, Dallas.
Some producers have already had to re-treat two or three times to protect crops, Knutson said.
And because grasshoppers thrive in hot weather, the problems they pose to crops will likely get worse before they get better, he said.
"As we get into the hot, dry summer, more and more of their wild host plants –- weeds and wild grasses — dry up, and that forces them into our crops, especially irrigated fields," he said.
