URGENT UPDATE: Lawn owners in Washington State are facing a new challenge as crows dig up their gardens—revealing the presence of an invasive beetle that is wreaking havoc on local grass. Experts confirm that the crows are not the real culprits but are actually seeking out the larvae of the European chafer, a beetle responsible for significant turf damage.
Reports from residents indicate that their once-lush lawns have turned into patches of dirt, with crows actively searching for grubs that feed on the roots of grass. John Marzluff, an emeritus professor of wildlife science at the University of Washington, stated, “(The crows are) killing the invasive pest that’s really destroying the lawn.” This natural pest control by crows may be alarming for homeowners, but it highlights an ecological imbalance stemming from the spread of the chafer beetle over the past decade.
As homeowners mourn their lawns, Jim Kropf, director of the Washington State University Pierce County Extension, suggests immediate measures to manage the situation. “Watering lawns seems to keep the beetles in check,” Kropf advises. The chafer beetles mate and lay eggs in the summer, making lawns particularly vulnerable during this period. Homeowners are encouraged to act now to protect their grass before the next breeding cycle.
In addition to watering, Kropf emphasizes the importance of timing when using insecticides. Spraying in the fall or winter months is ineffective, so spring treatments are crucial for achieving results. Homeowners can also consider diversifying their plants to create a more resilient ecosystem. Marzluff explains that planting a variety of species reduces the risk of pests overwhelming a single crop.

Despite the chaos, experts warn against feeding wildlife to avoid aggressive behavior from animals like raccoons. Kropf cautions, “If you feed, and then stop feeding raccoons, they can become very aggressive.”
As this situation develops, homeowners across Washington are urged to take proactive steps to mitigate the impact of these invasive beetles and the crows that are inadvertently helping with pest control. The measures taken now will determine the health of lawns in the upcoming months.
Stay tuned for more updates as experts continue to monitor the situation and offer guidance for maintaining healthy lawns in the face of these challenges.
