ELKO, Nev. — Jiminy Cricket! The Mormon crickets are invading Nevada’s Elko County, and their stampede over a hospital forced the creation of a Cricket Patrol to help visitors and patients get inside.
The patrol is using leaf blowers and brooms against the crickets to clear the way for those heading into the hospital, but no chemicals, spokesman Steve Burrows said. Northeastern Nevada Regional Hospital is using temporary staff for the patrol.

Mormon crickets are swept from an entrance to Northeastern Nevada Regional Hospital earlier this month as the latest invasion continues in Elko, Nevada.
“Some folks have a real aversion to crickets,” he said.
The visiting crickets seem to prefer the sidewalks and walls of the hospital this time rather than the parking lot, but in the big invasion of 2003, the hospital had to use golf carts to get people from their cars to the hospital, he said.
The hospital is just one example of the cricket invasion that involves slippery driving on highways and byways that calls for caution, and the state’s leading expert, Jeff Knight, told Elko County commissioners June 7 that baiting against the crickets started May 29.
He said the crickets are in Washoe, Pershing, Humboldt, Lander, Eureka and Elko counties, and they “made a very late hatch,” so they are smaller and only half grown — so far.
Knight told county commissioners his crew has been baiting in the county but his department can only bait on public land, and restricts applications to once a year to an area. Federal rules have “totally handicapped us,” he told commissioners.
“I understand you are hemmed in by regulations and hemmed in by environmentalists,” Commissioner Delmo Andreozzi said, suggesting activists should visit the Elko hospital “for a first-hand experience” with Mormon crickets. “I went to a meeting at the hospital, and the gutters were filled with cricket juice.”
With the Nevada Department of Agriculture restricted to public land, that means private property owners need to take their own steps against the infestation.
Mormon crickets have infested Elko County over the years, but they are cyclical. Knight said there is a four-to-six-year cycle, “and then they go away.” The dormant period in Elko County was 2007 to 2019, and then they started coming back, although not as heavily as this year.
Mormon crickets can’t fly but they can travel a mile a day and up to 50 miles during a single season, destroying sagebrush, grasses, small grains, alfalfa and vegetable crops along their way.
Knight also reported that clear-wing grasshoppers are making an appearance in Elko County, but so far the crop-imperiling pests have been seen only on private land.
“In fact, I’ll take Mormon crickets over grasshoppers any day as far as any damage that is done,” Knight said.

No household wants to face a pest problem, but over 14 million U.S. households encounter rodents, roaches, or other pests each year, according to the Census Bureau. These pests can trigger a variety of health concerns including asthma and may bring disease into the home. Once they establish themselves, pests can also damage the home itself and property inside.
Among the most common household pests are rodents and cockroaches, although termites also present a major threat in certain parts of the country. Seeking food and shelter, pests can creep into homes in a variety of ways, many of them related to the condition of the house. Problems like cracks or holes in a home’s walls, foundation, windows, or roof can provide openings into the home, while leaking water or sewer pipes provide the moist conditions that most pests prefer.
Given how pests establish themselves in homes, it is little surprise that pests—particularly rodents—tend to be seen more commonly in older units that have naturally deteriorated over time. More than one in five homes (22.7%) built before 1939 had a rodent sighting in the past 12 months, compared to just 1.8% of homes built since 2016. The data on home age and cockroach sightings is more complicated: cockroach sightings are most common in households built from the 1950s through the 1980s and less common before and after. This is likely in part because most of the oldest homes in the U.S. are found in areas where cockroaches are less common, while newer homes show less of the deterioration that allows roaches to enter the home.

For related reasons, a household’s income levels also bear a relationship to how frequently the home’s residents encounter pests. Among both owners and renters, the median income for households who had not seen a rodent or roach in the last 12 months was far higher than the median income for households who saw such pests daily. This is likely because households with greater means can afford to live in newer units or units that have been better maintained and keep up with the costs of ongoing maintenance and other preventive measures.

In addition to the age and condition of a home, where the home is located also impacts the type and frequency of pest issues. Rodents are usually more common in colder regions like the Northeast, where they seek out warm locations for shelter during the fall and winter months. Insects like cockroaches and ants thrive in warmer climates like those found in the South. And both roaches and rodents prefer more damp or humid climates, which make them less common in the dryer West. Taken together, these location-specific factors have a major impact on how likely a home is to face a pest problem.
To determine the locations with the worst pest problem, researchers at Construction Coverage calculated a composite index equally weighing the percentage of households with rodents and percentage of households with cockroaches for each location. The data used in this analysis is from the U.S. Census Bureau’s American Housing Survey. In the event of a tie, the location with the higher percentage of households with rodents was ranked higher. Only select metropolitan areas and states with data available from the American Housing Survey were considered in the analysis.
Here are the major metropolitan areas with the worst pest problem.
