LAS VEGAS—A migration of mild-mannered grasshoppers sweeping through the Las Vegas area is being attributed to wet weather several months ago.

Nevada state entomologist Jeff Knight told reporters on Thursday, July 25 the number of adult pallid-winged grasshoppers traveling north to central Nevada is unusual but not unprecedented and they pose no danger.

Knight said the grasshoppers are drawn to ultraviolet light sources and so switching to different lights would encourage them to leave.

“They attracted to the ultraviolet lights so you can consider changing the lights outside of your house and garage. If you go to a low UV or amber light, they will move on. You’ll see the most under bright white lights at night.”

“They don’t carry diseases or bite and probably won’t even cause any damage in your yards,” said Nevada state entomologist Jeff Knight. “They do not eat wood.”

He urged patience, as the critters will soon be gone.

“There is really no point in spraying your house because they won’t be around long enough,” Knight said. “They may lay 50-100 eggs that could hatch in the fall but they most likely won’t hatch because conditions are not right. They generally just eat weeds.”

He said there have been several similar migrations in the past 30 years, including one about six or seven years ago, adding that they’re typically linked to unusual weather patterns.

“It appears through history that when we have a wet winter or spring, these things build up often down below Laughlin and even into Arizona,” Knight told CNN. “We’ll have flights about this time of the year, migrations, and they’ll move northward.”

In 2019, the Las Vegas area recorded more rain in six months than the annual average of just under 4.2 inches per year.
