Mormon crickets are crawling onto the scene ahead of schedule across Utah this spring, and officials say those early, scattered bands could turn into serious outbreaks as the weather heats up. Sightings are already rolling in from wide stretches of the state, and ranchers, county agents and drivers are being told to stay alert. Farmers warn that the insects can strip forage in a hurry and, when crushed under tires, turn roads into a slick, messy hazard.
In an April 9 press release, the Utah Department of Agriculture and Food said, “We have identified limited hatching of Mormon crickets in multiple locations across the state so far this year” and noted it is coordinating early-season surveys with county partners and federal agencies. The department said its program focuses on early detection, close coordination with land managers and targeted treatments where populations reach set thresholds.
Where they're showing up
Early reports are coming in from southern, eastern and northern Utah as the season “is still taking shape,” according to The Salt Lake Tribune. State and local crews are still mapping the hot spots, and numbers are limited in most areas for now, but that can change fast if conditions tilt in the crickets’ favor.
Local trouble spots
In central Utah, people in and around Fillmore have reported heavy numbers and brought in contractors to spray, FOX 13 reported after visiting Millard County. Utah State University Extension experts told local reporters this emergence is “a little early” compared with typical hatching patterns and noted that many outbreaks start on federal rangelands before pushing into private fields.
Why they're early
Mormon cricket eggs hatch when spring soil temperatures warm to around 40F, and a warm, dry winter can bump that timing up, according to a species factsheet from Utah State University Extension. The extension also notes that drought years can concentrate feeding on what little green growth remains, which raises the odds that local groups will hit outbreak levels and damage forage for livestock.
Authorities mobilize
The federal Animal and Plant Health Inspection Service runs a Rangeland Grasshopper and Mormon Cricket Suppression Program that can offer technical support and help pay for targeted treatments on federal, state or private land once thresholds are met, according to APHIS. The agency says it prefers reduced-area treatments that alternate sprayed and unsprayed swaths to knock back migrating bands while giving predators and pollinators some safe ground.
How to protect property
Landowners are being urged to check known egg-laying beds, walk fence lines and other low-disturbance areas, and report any heavy concentrations to county extension offices or UDAF. Catching the insects early makes targeted control much more effective. Guidance from Utah State University Extension outlines management options and emphasizes working with local agents before applying pesticides so treatments are timed correctly and limited to the affected swaths.
The Utah Department of Agriculture and Food encourages landowners with concerns to reach out to their county extension office or the department for help. Officials say they will post updates on insect activity as the season unfolds, and that public reports of sightings are key to steering limited control resources where they are needed most.
