Significant Decline in Mesa County Japanese Beetle Population
After a successful summer treatment plan, Mesa County and the city of Grand Junction are celebrating an 85% reduction in Japanese beetle populations. Found in the city of Grand Junction in the summer of 2022, Mesa County declared the beetle a public nuisance species in March 2023. Joined by the Colorado Department of Agriculture (CDA), CSU Extension, and the City of Grand Junction, Mesa County has worked to eradicate the species, which is a threat to both crops and ornamental plants on the Western Slope.
