The spotted lanternfly has the potential to be a devastating invasive species wherever it goes. To date, the spotted lanternfly population has required many counties throughout several states to implement a quarantine to reduce the spread of these insects. They can feed on most plant species and affect businesses like vineyards, timber and other types of farms. The spotted lanternfly is known to cause economic and property damage unsurpassed by native pest species. Because spotted lanternfly damage can be extensive, it is suggested that a professional pest control company be contacted at first sight.
The spotted lanternfly was first discovered in Pennsylvania in 2014. They are believed to have been introduced from South East Asia around 2012. Since 2014, they have spread to more than seven states including New Jersey , Delaware and Maryland.
Spotted lanternflies are plant parasites and have been observed feeding on more than 70 species of plant. Among their favorites are tree-of-heaven, grapes, hops, hardwood trees, and fruit trees. It is also believed they can spread plant diseases. Due to the large numbers often feeding at once, they can greatly weaken a tree or plant. This may cause slowed growth and, in some circumstances, may even lead to the death of the plant. This can be catastrophic for many industries including forestry, viniculture, orchards, and landscaping.
How to Spot Spotted Lanternfly Damage?
When feeding, they expel a sweet sticky substance called honeydew. This substance often attracts ants and stinging insects in large numbers. The honeydew expulsion can be so high that it covers all surfaces beneath. Not only can this be unsightly and difficult to clean, but it also may support sooty mold growth. In some severe infestations during periods of warm weather, so much honeydew may be excreted that it appears to be raining from the tree above.
How Long do Spotted Lanternflies Live?
Females lay eggs beginning in September. These spotted lanternfly egg masses are deposited in rows and then covered with an excretion to better protect the eggs. This stage is potentially the most important for pest control specialists to manage. It is easier to kill eggs than the nymph spotted lanternflies that hatch. Each mass of eggs contains 30-50 young. Females can create 2-3 such egg masses in her lifetime. Sometimes eggs are not covered and left exposed. The covering will dry out and crack over time.
Spotted lanternfly eggs can be laid on almost any surface. This is the only stage of a spotted lanternfly’s life cycle that survives the winter. At Viking Pest, we eliminate spotted lanternfly eggs (in New Jersey Pennsylvania, Delaware and Maryland) from May to October. The good news is, only one generation per year occurs in this region. If we can control the egg population, we can mitigate the spotted lanternfly damage.
Once the lanternfly eggs hatch, they are into the second main stage of their life. This is the nymph or instar stage. There are four sub-stages within this portion of their life. During the first stage, they feed at a rapid pace. Their appearance also changes from only black with white spots to black with white spots and red patches towards adulthood.

All life stages feed exclusively on plants. They are not capable of biting or stinging, therefore pose no risk to people or pets. Juvenile-aged spotted lanternflies move quite quickly but cannot fly. Adults can readily fly and are excellent hitchhikers. All spotted lanternfly life stages are easily transported to an un-infested area, but eggs pose the biggest risk for spreading this pest. Therefore, it is important to control them at as early a stage as possible to prevent the spread of spotted lanternfly damage.
How to Identify a Spotted Lanternfly
There are four juvenile spotted lanternfly stages before adulthood. The juveniles look very different from the adults. Juveniles are black with white dots early in their development and are about 1/4” in length. As the juveniles grow, they become red and black with white dots and are approximately ½” long. Adults are mauve and rest with their wing held above their back. When the adults become excited, they open their wings and reveal a bright red coloration beneath their wings. This bright red makes it easy to identify the spotted lanternfly.
If you believe you have spotted lanternflies, we recommend obtaining one or more samples and place them in a vial with alcohol. This will allow the team at Viking Pest, to properly identify the insect in question.
How to Control Spotted Lanternflies from Spreading
While many controlled pest control products will stop this pest on contact, residual control is difficult to achieve. Spotted lanternflies can breed in such large numbers that they will repopulate in just a couple of days which requires reapplication. Therefore, it is not recommended to utilize most over-the-counter products to control this pest. Spotted lanternfly populations in New Jersey, Pennsylvania, Delaware and Maryland should be addressed by professional pest control companies like Viking Pest.
