Radnor Township Prepares Homeowners for Spotted Lanternfly Regional Invasion

Spotted Lanternfly

RADNOR, PA (August 7, 2019) - UPDATE:  The Spotted Lanternfly are very prolific. Please condemn the insect and discard. The Township will be providing sticky tape to help capture more. The tape is currently on backorder and once available we will notify our residents.

The Spotted Lanternfly (Lycorma delicatula) is a destructive insect that has invaded the Philadelphia region, including Radnor Township. The insect is native to China and was first detected in Southeastern Pennsylvania in September 2014. During the winter months, the eggs lay in wait for warmer weather and they have already been seen in the area this month. Spotted lanternflies are invasive and feed voraciously on many plants, including economically important crops like fruit trees, grapevines, hops, hardwoods, and ornamentals.

“Residents can take a few simple steps around their homes to reduce the risk of spotted lanternfly,” said John Hosbach, Jr., Urban Forester and Radnor Township Arborist. “However, please note that this subject problem is very complex and control is not easily obtained.”

According to the United States Department of Agriculture Animal and Plant Health Inspection Service, the spotted lanternfly is a hitchhiker. Be sure to inspect for the pest. Egg masses, juveniles, and adults can be on trees and plants and are also found on bricks, stone, metal, and other smooth surfaces. Also, thoroughly check your vehicles, trailers, and even the clothes you’re wearing because you can accidently move spotted lanternfly.

“As the forester and arborist for Radnor Township, we are managing risk and epidemics daily. We are taking strategic measures to ensure our woodlands and urban streetscape are protected through cultural and sound best management practices,” said Hosbach. 

Here are some quick facts and data sheets regarding the spotted lanternfly to serve as helpful tips for township homeowners:
