The Department of Agriculture and Markets updated New Yorkers Monday on its work to combat the spotted lanternfly.

The pests are invasive and destructive, especially to the agriculture industry. The insects leave damage like honeydew and sooty mold.

“This reduces photosynthesis and can actually predispose the plants to eat from other insects or from being more susceptible to other plant diseases,” says Christopher Logue, director of the Division of Plant Industry.

As the summer comes to an end and fall approaches, most spotted lanternflies are in their mature state, preparing to lay eggs. It is important to check vehicles and personal items for the insects before going on a road trip to guarantee they are not along for the ride.

“You also want to look at any sort of conveyances or goods that have been idle,” says Logue.

If you spot these insects, stomp on them to kill them.

“Definitely kill them. As many as you see,” advises Director of Science and Stewardship Danielle Begley-Miller.
