Spotted lanternflies are feasting on U.S. grapevines and putting vineyards at risk
The spotted lanternfly feeds on a wide range of ornamental, fruit and woody trees, including grapevines.
To try and keep the insects off, Shrawder wrapped his vines in special white nets. That didn’t work, but he said spraying insecticide on the trees surrounding the vineyard did help.
“It’s not successful completely – but we certainly reduce the insect bloat in the vineyard that way,” he said.
