What Are Spotted Lanternflies?
The spotted lanternfly (Lycorma delicatula) is an invasive planthopper insect native to Asia. First discovered in North America in Pennsylvania in 2014, it has since spread to several states, including Ohio, where it was first identified in 2020. The insect is known for its distinctive appearance: adults have gray wings with black spots and a bright red underwing, while nymphs are black with white spots, turning red as they mature.
Why Are They Bad?
Spotted lanternflies pose a significant threat to agriculture and natural ecosystems. They feed on the sap of over 70 plant species, including economically important crops like grapes, hops, and various fruit trees. This feeding can weaken plants, making them more susceptible to disease and other pests. Additionally, the insects excrete a sugary substance called honeydew, which promotes the growth of sooty mold, further damaging plants and making outdoor areas unpleasant.
How to Help Prevent the Spread
Preventing the spread of spotted lanternflies involves several proactive measures:
-
Inspect and Remove Egg Masses: During the fall and winter, look for egg masses on trees, outdoor furniture, vehicles, and other surfaces. Scrape them into a container of soapy water or alcohol to destroy them.
-
Check Your Belongings: Before moving outdoor items like firewood, garden equipment, or vehicles, inspect them for any signs of the insect.
-
Report Sightings: If you spot a spotted lanternfly, take a picture and report it to the Ohio Department of Agriculture through their Plant Pest Reporting tool.
What to Do If You Find Them on Your Property
If you find spotted lanternflies on your property, here are some steps you can take:
-
Manual Removal: Swat or stomp on the insects when you see them. This is most effective when populations are low.
-
Use Insecticides: For larger infestations, consider using insecticidal soaps, horticultural oils, or contact insecticides like bifenthrin or carbaryl. Always follow label instructions and consider consulting a pest management professional.
-
Remove Host Plants: Removing plants that spotted lanternflies prefer, such as the tree of heaven, can help reduce their numbers.
By staying vigilant and taking these steps, you can help protect Ohio's agriculture and natural landscapes from the damaging effects of the spotted lanternfly.
