The spotted lantern fly is a harmful invasive species that poses a significant threat to agriculture due to its feeding habits on crops. These flies are not native to the United States and can damage plants and make them less productive. Praying mantises, bright green insects, are one of their biggest predators, occupying many of the same areas as spotted lanternflies and consuming them.
While ladybugs are known to feed on other pests like aphids and mites, there is no substantial evidence to suggest they prey on spotted lanternflies. Further research is needed to determine if these insects prey on spotted lanternflies.
Many farmers use ladybugs to naturally control pests, but there are 13 things these insects love to eat and 5 they don’t. Aphids are one of the pests they don’t like. Scientifically based pest management is the best way to kill spotted lanternflies, and it’s important to avoid using homemade remedies or over-the-counter products.
Agricultural officials across multiple states have asked residents to kill the bugs on sight or scrape egg shells to prevent them from eating spotted lanternfly eggs. Lanternfly bugs can be easily killed using a mixture of dish soap, with dawn dish soap being effective.
Despite their destructive nature, spotted lanternflies have caused significant damage to certain plants and crops, especially in large numbers. Some general predators, such as praying mantis, wheel bugs, and spiders, have been observed eating spotted lanternflies. Researchers are also finding that spotted lanternflies make a tasty meal for some birds and other bugs.

What Insect Kills Lantern Flies?
One known predator of spotted lanternflies is the wheel bug, which has been increasingly observed feeding on them. To manage these pests on your property, two primary methods are available: immediate removal using approved insecticides or securing egg masses for local EPA analysis. Effective insecticides that target lanternflies include imidacloprid, bifenthrin, dinotefuran, neem oil, and soybean oil. Products like Ortho® BugClear™ can kill spotted lanternflies upon contact.
Additionally, squashing or vacuuming them is a simple removal method. Depending on their life stage, lanternflies can be mistaken for ticks or other insects. Contact insecticides can eliminate them within hours or days, though less-toxic options require thorough coverage. A strategic approach involves removing female tree of heaven plants, while keeping a male to attract lanternflies to treat with systemic insecticides. To target all life stages, GardenTech's Sevin Insect Killer is effective in both concentrate and ready-to-spray forms.
Although spotted lanternflies do not significantly damage most trees or crops, they impact grapevines and other plants. Continuous research aims to find optimal removal methods, as no insecticide is specific to lanternflies, thus there is a risk of harming beneficial insects during application.
Do Spotted Lanternflies Have Predators?
The spotted lanternfly, an invasive species in the U. S. for nearly a decade, lacks specialized native predators, allowing its population to expand rapidly. Some natural enemies do exist, and scientists are exploring biological control methods for this invasive insect. Various predators have been observed attacking the lanternfly, including praying mantises, spiders, wheel bugs, and birds. However, these predators are insufficient in numbers to significantly control lanternfly populations, leading to sightings of hundreds on individual plants or trees.
Research by federal scientists in Delaware indicates that understanding and leveraging natural predation could assist in managing spotted lanternfly populations. Observations captured by enthusiasts have highlighted numerous predators consuming these planthoppers, contributing to a wider research initiative. Despite some newfound potential predators like cardinals and tiny dustywings, the overarching challenge remains the overwhelming lanternfly numbers which often outpace predation efforts.
The USDA warns of the threat the spotted lanternfly poses to various fruits, such as apples, grapes, and peaches, along with some tree species. Without effective control, this invasive pest continues to proliferate, highlighting the need for further studies on biological control mechanisms that could help mitigate its impact.
Are Spotted Lanternfly Bugs A Threat?
Spotted lanternflies, native to Asia, were first detected in Pennsylvania in 2014 and have since spread to 14 states, becoming one of the most destructive invasive insects in 150 years, according to Pennsylvania State University. These sap-sucking insects devastate trees, grapevines, and various fruit crops, posing significant threats to agriculture, forestry, tourism, and the economy. USDA scientists have identified a potential vulnerability in the lanternflies’ attraction to vibration, which could aid in controlling their population.
Despite their harmful impact on plants, there is little evidence that they pose a direct ecological threat beyond plant damage, and currently, they do not harm humans or animals. However, their presence leads to crop losses, export issues, and increased management costs, making them a major economic and lifestyle pest.
Efforts to control the spread include public advisories to eliminate the bugs and intercepting their eggs on firewood, construction materials, military equipment, and nursery shipments. Recent analyses indicate that spotted lanternflies are becoming active earlier and remaining active later in the year, likely extending their damaging period. Officials in states like Connecticut emphasize the severe threat lanternflies pose to the environment and agricultural industries, urging residents to take action against them.
While lanternflies are more of a nuisance than a high risk to the broader ecosystem, their ability to damage over 70 woody plant species and their rapid spread continue to challenge affected regions. Ongoing research and public cooperation are crucial in mitigating the impact of this invasive species.
Do Spotted Lanternflies Kill Trees?
Healthy ornamental trees typically do not die from spotted lanternflies, although branch dieback and health decline have been noted, particularly in black walnut and maple, which are favored hosts. If you see these pests on your plants, effective removal methods include stomping them or using a soap and water mixture that is sufficiently soapy to prevent them from drying off. Adult and nymph lanternflies damage trees by feeding on sap from various parts.
While they have been known to kill sapling trees, sumac, grapevines, and tree-of-heaven, established ornamental trees have generally shown resilience. Recent research from Penn State suggests hardwoods like maple, willow, and birch may not be as vulnerable as initially believed. Despite their feeding habits, spotted lanternflies do not appear to harm most trees nor agricultural crops. However, they significantly impact grapes and related crops. The honeydew they excrete can lead to sooty mold growth, attracting secondary pests.
Spotted lanternflies are known to feed on over 100 plant species but rarely kill them outright. While they do not directly kill trees, they induce stress that necessitates good management practices, such as effective water and soil management, to maintain tree health. Thus, while the presence of spotted lanternflies is concerning, they are less destructive than previously assumed, especially regarding mature trees.
Why Shouldn'T You Kill Ladybugs?
Ladybugs, or ladybird beetles, are beneficial insects known for their vibrant red color and appetite for pests like aphids and mealybugs. Implementing ladybugs in your garden can effectively help manage pest populations, but it's crucial to maintain other pest control measures as well. While ladybugs can assist in controlling unwanted insects, they should not replace professional pest control practices. It’s best to attract native ladybugs to your garden rather than purchasing potentially diseased ladybugs, which can threaten local ecosystems.
Ladybugs are considered "gardeners’ best friends" due to their voracious appetites—one ladybug can consume up to 50 aphids daily, totaling over 5, 000 in its lifetime. However, swarms of ladybugs can become a nuisance inside homes, particularly during winter. If you encounter them indoors, it is advisable to use gentle removal methods, like vacuuming or natural repellents, instead of killing them, as they do not pose any known health risks to humans.
While their presence indicates a healthy ecosystem, an excessive number of ladybugs could signal a potential infestation, which should be addressed. Ladybugs contribute positively by controlling aphid populations and other pests, making them invaluable to gardens. Therefore, while you may need to manage their numbers indoors, it's important to protect and encourage their presence outdoors for effective pest control.
How Does China Deal With Lanternflies?
In China, Dryinidae wasps demonstrate up to 60% effectiveness in killing juvenile spotted lanternflies, a nonnative invasive planthopper that threatens agriculture and tourism by attacking over 70 woody plant species. While these insects pose significant problems outside their native range—China, Taiwan, and Vietnam—they are kept in check at home by natural predators like A. orientalis and the parasitic wasp Dryinus sinicus. Dryinus sinicus lays its eggs in lanternfly nymphs, leading to their death as part of its reproductive cycle.
Research is ongoing regarding the introduction of these wasps to new ecosystems and the implications for lanternfly control. USDA scientists have discovered spotted lanternflies may be drawn to vibrations, providing a promising avenue for control efforts. In Delaware, scientists are exploring biocontrol measures against this invasive pest, originally thought to have arrived in the U. S. through unknown pathways from its native regions. Although some natural predators, including Dryinus sinicus and Ooencyrtus kuvanae, have been identified in the lanternfly's native habitat, they are not yet employed in the U.
S. for biocontrol. Additional studies aim to understand these wasps' impact and potential cooperation with native predators. Effective control methods may involve encouraging these native wasps to target spotted lanternflies while combining early detection measures, such as trapping, to contain the pest's spread. Biosecurity and comprehensive research remain vital components in managing this ecological threat.
What Plants Do Spotted Lanternflies Destroy?
The spotted lanternfly (Lycorma delicatula) is an invasive planthopper that poses a threat to various plants, including grapes, hops, stone fruits, and hardwoods. This pest excretes a sticky, sugary substance while feeding, leading to sooty mold that further damages plants. Primarily using the tree of heaven (Ailanthus altissima) as its host, the lanternfly has been documented feeding on over 100 different species, including willows, maples, black walnuts, and numerous fruits like apples and blueberries.
Despite their extensive feeding habits, they do not appear to cause significant damage to all types of trees or most crops, but their feeding can weaken sensitive plants, notably grapevines, causing issues such as oozing trunks and dead branches.
To mitigate the spread of spotted lanternflies, cutting down high-risk host plants like the tree of heaven during mid-summer to early fall is suggested. DIY solutions against these pests may inadvertently harm other plants or pets. While the lanternflies can stress plants and cause localized damage, they are known to kill primarily grapevines and the tree of heaven. Their feeding behavior is damaging, and they affect plants through all life stages.
Though found on crops like soybeans and corn, there is no evidence of them feeding on these plants. Overall, control measures, including traps and sprays, are critical for managing this invasive species and protecting valuable crops.
Which Color Ladybugs Are Poisonous?
Orange ladybugs, primarily Asian lady beetles, often contain the highest levels of toxins, making them potentially the most allergenic to humans. In contrast, red ladybugs are generally more predatory and capable of defending themselves. Various ladybug species exhibit a range of colors and patterns, with many displaying bright red, orange, or yellow shades adorned with black spots. This bright coloration serves as a warning to predators about their toxicity, a phenomenon known as "aposematic coloration." Although studies have confirmed that ladybugs in colors such as black, orange, red, yellow, and spotted patterns can be poisonous, many species remain untested for toxins, implying that other colors might also be toxic.
Interestingly, the presence of bright colors in ladybugs decreases the likelihood of being preyed upon, as predators learn to associate these colors with potential dangers. Orange-tinted ladybugs, which are invasive and range from dark red to light orange, possess a strong odor that helps repel predators. Overall, while ladybugs are generally not poisonous to humans, they may be distasteful or potentially harmful if ingested by pets or humans. Brightly colored ladybugs should be approached with caution, acknowledging their potential toxicity.
