Spot the Spotted Lanternflies

The spotted lanternfly, an invasive insect native to eastern Asia that can damage crops, has recently spread throughout Maryland. This pest, also known as Lycorma delicatula, does not bite or sting and is primarily a nuisance pest in home gardens, but is considered a threat to agriculture. Maryland residents are urged to report sightings of spotted lanternflies to the Maryland Department of Agriculture.

Here’s how to help: Scrape egg masses — found on tree trunks and flat surfaces during the fall into early spring — into a sealed bag with hand sanitizer or alcohol and dispose of it in the garbage. Squash all other stages of the insect when found throughout the year.

Report sightings of any of the life stages to the Maryland Department of Agriculture at bit.ly/ReportSpottedLanternflies. Pesticides are not recommended to manage spotted lanternflies. Many natural predators, such as bats, are learning to feed on the invasive insects. Spraying insecticides, including home remedies, can also harm butterflies and other beneficial pollinators and native insects.
