Overview of the spotted lanternfly

The spotted lanternfly, scientifically known as Lycorma delicatula, is an invasive pest native to Asia. It was first discovered in the United States in Pennsylvania in 2014, and has since spread to other states.

This insect primarily feeds on plant species, with a preference for tree of heaven, grapevines, and fruit trees. Unfortunately, it is not picky and can infest over 70 different types of plants.

The spotted lanternfly has no natural predators in the United States, which allows its population to grow rapidly. The severity of the issue is reflected in the classification of spotted lanternflies as a destructive pest.

It poses a significant threat to agriculture, as it can waste entire crops and destroy fruit trees. In addition to the direct damage it causes, the spotted lanternfly also excretes honeydew, a sticky substance that leads to the growth of black sooty mold.

This mold not only affects the plants it lands on but also reduces their photosynthetic capacity, hindering their ability to grow.

Impact of spotted lanternflies

The impact of spotted lanternflies extends far beyond the agricultural industry. These insects can cause extensive damage to forests, vineyards, and gardens.

The waste product, honeydew, affects the aesthetics of plants, coating them in a sticky residue that attracts other insects. Additionally, the mold growth resulting from the honeydew can lead to the premature death of plants.

In vineyards, spotted lanternflies feed on grapevines, leading to economic losses for growers and potentially affecting the quality of the grapes. The damage to gardens is equally concerning, as these insects can quickly decimate ornamental trees and plants.

The invasive nature of spotted lanternflies threatens biodiversity, as they outcompete native insects and disrupt the delicate balance of ecosystems.

Understanding the Spotted Lanternfly

Life cycle and appearance of the spotted lanternfly

To effectively combat the spread of spotted lanternflies, it is crucial to understand their life cycle. These insects go through several stages of development, starting as eggs before hatching into nymphs.

The young nymphs are black with white spots and gradually transition into larger, red-and-black nymphs known as instars. As they continue to grow, spotted lanternflies eventually reach their adult form, characterized by their vibrant red wings with black spots.

Throughout their development, spotted lanternflies undergo molting, shedding their old exoskeleton to accommodate their growing bodies. This molting process leaves behind white, waxy patches, which can be seen on trees and other surfaces where the insects have been present.

Signs of spotted lanternfly infestation

Identifying signs of spotted lanternfly infestation is essential for early detection and effective management. One key indicator is the presence of egg masses, which are laid in rows along various surfaces, such as tree trunks, outdoor furniture, and vehicles.

These masses look like grayish, mud-like patches and can contain 30 to 50 eggs each. In addition to the egg masses, another telltale sign of infestation is the damage caused to plants.

Spotted lanternflies pierce plant tissue to feed on the sap, leaving behind weeping wounds and causing wilting or yellowing of leaves. The feeding activity can be quite destructive, especially when large numbers of these insects are present.

Another consequence of spotted lanternflies’ feeding is the production of honeydew, which can accumulate on leaves and other surfaces. This sticky substance serves as a breeding ground for black sooty mold, leading to the further deterioration of plants.

Recognizing these signs can help prevent the spread of spotted lanternflies and minimize the damage they cause. Conclusion: (Do not write a conclusion)

Methods for Getting Rid of Spotted Lanternflies

Removing eggs and reducing hosts

When it comes to combating spotted lanternfly infestations, it is crucial to target both the eggs and their preferred host plants. By eliminating the eggs and reducing the number of available hosts, you can significantly reduce the population of these invasive pests.

One effective method is manually removing the eggs. Egg masses can be scraped off surfaces using a plastic card or similar tool and deposited into a bag filled with rubbing alcohol or hand sanitizer to kill them.

It’s important to carefully inspect surfaces such as tree trunks, outdoor furniture, and vehicles for these egg masses, as they can blend in and be easily overlooked. Reducing the number of host plants is another essential step in managing spotted lanternflies.

Tree-of-heaven (Ailanthus altissima) and Chinese sumac (Ailanthis altissima) are two of their preferred hosts. Removing these plants from your property or employing professional help to treat them can greatly disrupt the spotted lanternfly’s lifecycle and population growth.

To further prevent lanternflies from infesting your trees, you can use sticky banding tape. Wrap the tape around the trunk of the tree, ensuring it creates a complete barrier.

The sticky surface traps the nymphs and adult lanternflies attempting to climb the tree, preventing their progress and eventually causing their demise.

Natural methods and predators

Harnessing the power of natural predators can be an effective way to control spotted lanternfly populations. Encouraging the presence of animals that naturally prey on the insects can help to keep their numbers in check.

Gray catbirds (Dumetella carolinensis), for example, are skilled insectivores and have been observed feeding on spotted lanternflies. By creating an environment that attracts these birds, such as providing water sources, shrubs for cover, and native plants for food, you can encourage their presence and promote natural control of the lanternfly population.

Other natural predators include cats, dogs, ducks, wheel bugs, and green frogs. While these animals may not completely eradicate the pests, they can help to reduce the population and keep their numbers under control.

However, it is essential to consider the potential ecological impact before implementing these methods, as large-scale introductions of non-native predators can cause unintended consequences.

Homemade spray

For those looking for alternative methods, homemade sprays can be used to deter and control spotted lanternflies. These sprays are typically made with common household ingredients and are safe for both people and pets.

One recipe for a homemade spray involves combining one part white vinegar with one part water. Adding a few drops of essential oils like neem oil, lavender oil, tea tree oil, and peppermint oil can enhance the effectiveness of the spray.

Adding a small amount of dish soap can help the solution adhere to the insects and disrupt their protective coating, rendering them more susceptible to harm. To apply the homemade spray, pour it into a spray bottle and thoroughly coat the leaves, stems, and affected areas of plants.

It’s important to reapply the spray after rain or irrigation to maintain its effectiveness.


Traps can be a useful tool in the battle against spotted lanternflies. They can capture and kill both nymphs and adult lanternflies, helping to reduce their numbers and prevent further infestations.

One type of trap that can be effective is a neem oil trap. Neem oil, derived from the neem tree, has natural insecticidal properties and can be mixed with water and applied to sticky traps.

The scent of the neem oil attracts the lanternflies, and once they come into contact with the sticky surface, they are unable to escape. Another trap option is a vinegar trap.

Fill a shallow dish with vinegar and add a small amount of dish soap. The vinegar acts as a lure, and the dish soap disrupts the surface tension, causing the lanternflies to drown when they come into contact with the liquid.

Regularly monitoring the traps and emptying them as needed is crucial to their effectiveness. Placing traps strategically around your property, especially near high-risk areas and host plants, can improve their efficacy in trapping and eliminating spotted lanternflies.


In severe infestations, using insecticides may be necessary to control spotted lanternfly populations. However, it is vital to handle and use these chemicals with caution to minimize the potential harm to the environment and non-target organisms.

When choosing an insecticide, it is essential to select one that is specifically labeled for use against spotted lanternflies and follow the instructions provided by the Environmental Protection Agency (EPA). Additionally, wearing protective clothing, such as gloves and goggles, is crucial to ensure personal safety during the application process.

Selective insecticides that target lanternflies while minimizing harm to flowering plants and pollinators are preferred. Applying insecticides to registered sites, such as infested trees and specific problem areas, rather than blanket spraying, helps to minimize their overall impact on the environment.
