HUNTINGDON VALLEY, PA, UNITED STATES, August 5, 2021 / — Spotted Lanternfly are being reported all over Philadelphia, Bucks and Montgomery Counties. First spotted in 2014, Penn State’s Agriculture Extension has been monitoring Spotted Lanternfly and issuing warnings about this invasive insect. They’re a problem for local farmers who are losing fruit and timber crops to the insects’ voracious appetite. Homeowners are also seeing impacts that range from annoying to significant damage.

Spotted Lanternfly Harms Trees

The Spotted Lanternfly feeds primarily on the Tree of Heaven, which is common throughout the region. Unfortunately, these flies also swarm other types of trees, including Black Walnuts, Maples, Apples, Willows, and many more. According to the PA Department of Agriculture, they attack more than 70 species of trees, and 25 of them are found in Pennsylvania.

At this point, it’s hard to determine the long-term damage to trees. Penn State has been following the Spotted Lanternfly and monitoring infested trees for several years. While it’s still too early to say what the long-term effects will be, the insects are definitely causing significant die-back and defoliating branches in trees.

Spotted Lanternfly Causes Property Damage

These insects eat tree sap and then excrete droppings of a sweet, sticky substance called Honeydew. The honeydew will coat the tree, the base of the tree, and anything underneath the tree, including cars, hardscapes and decking. Then, black, sooty mold grows on the secreted substance. The combination of honeydew and black, sooty mold has an unpleasantly sour stench and is very difficult to remove from surfaces.

Spotted Lanternfly Attracts Dangerous Insects

The secreted honeydew attracts stinging wasps, who can’t resist the tantalizing smell of the honeydew. Stinging wasps are particularly a problem for children playing in the area.

How to Get Rid of Spotted Lanternfly

“We are fully prepared to combat the Spotted Lanternfly,” says Matt Giroud, Director of Field Operations at Giroud Tree & Lawn. “We are prepped and ready to treat these trees. The challenge is making the community aware of the problem.”

Adult Spotted Lanternfly should be squashed and killed. However, these insects will attack a tree in swarms, making it difficult to squish them all. Chemical treatments may be necessary for large infestations of Spotted Lanternfly on a property.

Homeowners should call an ISA Certified Arborist if there are signs of Spotted Lanternfly on the property. Penn State and the PA Department of Agriculture have recommended a two-part treatment program to eliminate Spotted Lanternfly.
July-Mid-September: Dinotefuran is applied as a Basal Trunk Spray. For a few weeks after treatment, the insects are killed on contact or when they crawl on treated surfaces. After the insecticide is absorbed through the tree’s vascular system, Spotted Lanternfly are killed when they feed on the tree.

September-Mid-November: Bifenthrin is sprayed on trees with Spotted Lanternfly. This treatment kills the insects on contact and when they walk over surfaces with the residue on it.
