The Spotted Lanternfly is a destructive insect that has invaded the Philadelphia area. All winter long, their eggs lay waiting for the warm weather, carefully encased in a protective, hardened layer of secretion. Once they emerge as nymphs, it is time to take action! Read on to find out how to identify and combat Spotted Lanternfly in the Nymph stages.
How to Identify Spotted Lanternfly Nymphs
Spotted Lanternfly goes through several identities during its life cycle. Adult females lay eggs in the fall, and they cover the egg masses in a secretion. This secretion dries hard and camouflages to look like dirt or clay. The young nymphs that emerge from the eggs in spring are black with white spots. In early summer, they gain red markings on their bodies. Later in midsummer, they become adults and shed their skin to form wings on their backs.
How to Get Rid of Spotted Lanternfly Nymphs
The experts at Giroud Tree and Lawn have been working closely with Penn State University’s Department of Entomology and Cooperative Extension to determine the best treatments and techniques for combating Spotted Lanternfly in each of the life cycle stages. According to Penn State:
“Currently, the most effective trap for SLF is a sticky band wrapped around the trunks of trees. SLF nymphs and adults are trapped in the sticky barrier as they crawl up from the ground onto the trunks and move upward to feed on the tree./”
Sticky bands can be found at most hardware stores and also on Amazon.com. They are easy to install, but they should be changed weekly for the best results. However, it is important to be aware that these sticky bands can accidentally trap other insects and also small animals and birds. To avoid this problem, Penn State recommends cutting the sticky bands lengthwise so the surface area is not as broad. Spotted Lanternfly Nymphs are small and climb up the tree. They will get trapped at the bottom of the sticky band, so there is no need to have such a tall band. Penn State also urges homeowners to wrap the outside of the tree with chicken wire over the area of the sticky band. This will prevent squirrels, birds, and other small animals from becoming stuck to the band.
