Spotted Lanternfly Egg Mass Characteristics
Spotted lanternfly (SLF) egg masses are a crucial stage in the life cycle of this invasive insect species. Laid during late summer and early winter, with the majority occurring in October, these egg masses serve as the incubation site for future generations of spotted lanternflies. Each egg mass contains an average of 30-50 eggs, and a single female can lay at least two egg masses. These egg masses are typically around 1.5 inches long and colored brown or grey.
Upon close inspection, one can observe that the egg masses consist of rows of small eggs, approximately the size of a sharpened pencil point. The color of the eggs can vary from yellow to brown, and after being laid, the female covers them with a protective substance. This substance aids in their survival throughout the winter and protects them from predation. However, it’s worth noting that if an egg mass remains uncovered, it has a 10% lower hatch rate on average, though it can still hatch. The lack of covering in these cases may be due to disturbances from humans, other spotted lanternflies, or potential predators.
Important: Egg masses that have not been laid by the female will not hatch.
Differentiating between fresh and old egg masses requires attention to detail. Fresh egg masses have a complete covering and no emergence holes, while old egg masses may have a faded covering and possibly emergence holes at the top. Additionally, spotted lanternfly females exhibit a preference for laying eggs next to already existing egg masses, further increasing the need for effective egg mass destruction.

Uncovering And Disturbances Of Egg Masses
The destruction of spotted lanternfly (SLF) eggs is crucial in curbing the population growth and spread of this invasive species. Therefore, identifying and destroying these eggs is a crucial step in managing their impact.
Egg masses can be found primarily on trees, with preferred hosts including red maple, silver maple, willows, black cherry, and pine trees. However, reaching and destroying these egg masses can be a challenge, as less than 2% of the egg masses on a tree are within reach, while the rest are located above reach.
It is worth noting that destroying and reporting SLF egg masses found in newly added quarantine zones is particularly helpful. If an egg mass is discovered outside of the quarantine zone, it should be reported immediately and destroyed to prevent the spread of the invasive species to unaffected areas. A SLF permit is also necessary for businesses transporting vehicles or conveyances within the quarantine zone.
Identifying Fresh And Old Egg Masses
Differentiating between fresh and old egg masses is not always a simple task, but it is essential for effective targeted destruction. Fresh egg masses can be identified by checking for the presence of a covering and emergence holes. If an egg mass has a complete covering and no emergence holes, it is likely fresh. On the other hand, old egg masses may have a faded covering and potential emergence holes at the top.
This distinction is crucial as destroying fresh egg masses can remove up to 50 spotted lanternflies from the next generation. By targeting fresh egg masses, individuals can significantly impact the future population growth of this invasive species. Therefore, it is recommended to focus efforts on identifying and destroying fresh egg masses whenever possible.
Effective Methods To Destroy Egg Masses
To effectively destroy spotted lanternfly egg masses, various methods can be employed. The most straightforward approach involves scraping or smashing the egg masses.
When using the scraping method, the egg masses should be scraped into a bag or container filled with rubbing alcohol or hand sanitizer. This ensures that the eggs are effectively killed and unable to hatch.
Similarly, the egg masses can be smashed with even and forceful pressure, ensuring the destruction of the nymphs inside.
It is crucial to note that while smashing or scraping the egg masses may reduce the number of nymph or adult spotted lanternflies, it may not entirely eliminate the population. However, these methods offer a straightforward and accessible means of combating the spread of this invasive species.
- Scrape the egg masses into a bag or container filled with rubbing alcohol or hand sanitizer
- Smash the egg masses with even and forceful pressure
Ovicidal Action Of Insecticides On Spotted Lanternfly Eggs
Beyond manual removal techniques, insecticides can also be utilized to target spotted lanternfly eggs and prevent their hatching. Research has shown that some insecticides exhibit ovicidal action against spotted lanternfly eggs, providing enhanced control.
- Certain paraffinic and/or mineral oils, such as JMS Stylet oil, Damoil, and Lesco Horticultural oil, have proven effective in killing up to 75% of treated eggs when applied at a solution of at least 3%.
- Soybean oil, when applied at a 50% concentration, has also demonstrated similar control.
- For effective results, these oils should be applied with good coverage and direct application to the egg masses.
Utilizing insecticides with ovicidal abilities provides a safe and environmentally friendly option with minimal non-target effects.
Research on additional ovicides is ongoing to provide increased control and management strategies for dealing with spotted lanternfly eggs.
Recommended Techniques To Remove And Dispose Of Egg Masses
To effectively remove and dispose of spotted lanternfly egg masses, it is essential to follow recommended techniques. The best time to find and destroy eggs is during winter to early spring, prior to their hatching. These egg masses can be found on various surfaces, including tree trunks, branches, rocks, and outdoor equipment.
A simple and recommended method involves applying pressure to the egg masses, causing them to pop and kill the nymphs inside. Using a scraper card and pressing down firmly will create pressure and an audible popping sound, indicating the destruction of the eggs. Alternatively, the eggs can be scraped off any surface using a plastic card, then placed into a bag filled with hand sanitizer or alcohol to ensure their death.
After removing the egg masses, it is crucial to dispose of them properly. The scraped eggs should be sealed tightly in a bag or container and placed in the trash. For further containment, the trash should then be taken to the dump.
