"They're just on a roll. They're going to continue to populate and flourish and move onward into new territories," said New Jersey Secretary of Agriculture Douglas Fisher.
The colder weather will kill off any adult lanternflies bugging New Jersey right now, but come spring, the destructive pest is predicted to continue its spread throughout the state.
"We are targeting areas where severe infestations have been confirmed, and we also encourage residents to destroy the Spotted Lanternfly if possible when they see it," said New Jersey Department of Agriculture Secretary Douglas Fisher.
