To help slow the spread of a sap-sucking plant pest moving across the United States, pest management officials are enlisting the help of man’s best friend.

Kansas State University wildlife expert Drew Ricketts explained that conservationists are training dogs to detect the Spotted lanternfly, an invasive pest native to Asia. First detected in Pennsylvania in 2014, the pest is believed to have arrived via goods shipped overseas. The Spotted lanternfly feeds on various plants, including grapes, hops, stone fruits, and hardwood trees. As it feeds, it releases a sticky fluid that causes sooty mold, further harming plants. The USDA estimates that 18 states have some level of infestation.

Ricketts said wildlife experts are using all available methods to contain the pest’s spread, including utilizing dogs’ exceptional sense of smell. Dogs can be trained to detect Spotted lanternflies, aiding in early detection and rapid response. While humans may be better at spotting the pest in vineyards, Ricketts noted dogs are three times more effective in forested areas.

Once detected, invasive species managers can begin eradication methods, such as scraping eggs off stems, applying insecticides, or using biological controls. Ricketts added that conservation canines are also trained for other tasks, including locating bird nests for research studies.
