Unwelcome Hitchhikers, Spotted Lanternflies Infesting Greenwich. Squash these pests.

Spotted Lanternflies are in Greenwich. Native to China, this is an invasive pest that threatens American agriculture and natural resources.

They feed on a wide range of plants and trees, including grapes, apples, walnut, and oak.

One of their preferred hosts is the invasive Tree-of-Heaven, but these pests spread easily by hitchhiking on vehicles or laying its eggs on most any flat surface – like the sides of box cars, propane tanks and equipment stored outside.

The Spotted Lanternfly was first detected in in 2014 in Pennsylvania, where they have taken over forests, backyards and vineyards.
