Citizens are urged to be careful not to bring the Spotted Lantern Fly (SLF) home with them as a hitchhiker. People driving out of state or to parts of Ohio with known infestations should inspect and/or wash their vehicles upon return to ensure these insects have not accidentally traveled back with them.

Spotted Lantern Fly (SLF) which is an invasive plant hopper that is native to China was found in Pennsylvania in 2014. In late 2020, SLF was found in southern Ohio in Mingo Junction and in northern Ohio, Cuyahoga County in 2021. It is a major pest of crops including grapes, apples, hops, walnuts and hardwood trees. Nymphs and adults prefer to feed on the invasive tree of heaven (Ailanthus altissima) but can feed on more than 70 plant species, and has the potential to greatly impact the viticulture, tree fruit, nursery, and timber industries.
The insects suck sap from stems and branches which can weaken and damage the plant. The feeding can result in oozing sap, wilting, leaf curling, and dieback. In addition, during feeding the SLF secretes honeydew which can buildup on and underneath the plant, which in turn promotes the growth of black sooty mold.

Black sooty mold around the base of plants or oozing sap may indicate the presence of the spotted lanternfly, however other pests can cause these symptoms as well. Black sooty mold is harmless to people however it causes damage to plants. In counties infested and quarantined for spotted lanternfly, residents report hundreds of these insects that affect their quality of life and ability to enjoy the outdoors during the spring and summer months. Spotted lanternflies will cover trees, swarm in the air, and their honeydew can coat decks and play equipment.

SLF will lay eggs beginning in October through the beginning of winter. The egg masses of the SLF are small, grey masses protected by a waxy covering. After hatching in late spring, the SLF goes through four nymph stages. During the first three they appear black with white spots, and in the last stage, which typically occurs during mid-summer, they are red with white dots and black stripes. During the late summer and autumn, the SLF is in the adult moth stage. These adults are larger (approximately 1 inch), with black bodies and brightly colored wings.

Spotted lanternfly, which likely arrived on imported goods from Asia, is a plant hopper and not a strong flier. It is moved greater distances by people moving infested materials. It lays eggs on almost any surface, including vehicles, trailers, outdoor equipment, patio furniture, etc. Egg masses can be removed by scrapping with a hard or rigid tool and disposed of into a container of rubbing alcohol.
Early detection is critical to prevent economic and ecological losses. The public has played a key role in detecting spotted lanternfly and the success of stopping its spread depends on help from the public to look for and report signs of the pest.

If you suspect a spotted lanternfly infestation, at any life stage, please report the finding to the Ohio Department of Agriculture Plant Pest Control (614-728-6400, plantpest@agri.ohio.gov), your local OSU Extension specialist (https://extension.osu.edu) or by using the Great Lakes Early Detection mobile reporting app (https://apps.bugwood.org/apps/gledn/).

It is hard to believe but our food waste and other organic materials such as paper and yard trimmings equate to nearly 55% of our total waste with food making up 20-30% of this total.  When these items are in our landfills they breakdown and create a material called leachate, which is toxic and can pollute groundwater, surface water and soil. Vermicomposting, a process that relies on earthworms and microorganisms to break down organic matter and transform it into a product that can be used as a valuable soil amendment and source of plant nutrients, can help homeowners with their gardening efforts but also keeps organic materials from causing problems in the landfill!
Vermicomposting is a way to get earthworms to work for you in a more organized way. You can become a worm farmer easily. North Carolina State University Extension is a leader in vermicomposting. Rhonda Sherman with North Carolina Extension, states that you need 4 items to begin worm farming.

1. Worm Bin – You can purchase this through many different garden centers and websites. You can even make this on your own. If you choose to make your own bin, make sure that it has a tight fitting lid and is a dark color. The bin size depends on the amount of food discards produced by your household. According to North Carolina State University, “The general rule of thumb is one square foot of surface area for each pound of food discards generated per week. So if your household creates two pounds of food scraps weekly, you will need a 2-foot by 1-foot worm bin that is 8 to 20 inches deep.” To access plans simply search on the internet for, DIY worm bin.
2. Bedding – Bedding is needed to provide a good living environment for the worms. Bedding should be a material that is nontoxic, holds moisture, and allows air circulation. Items to use could be, shredded paper, newspapers, paper bags, office paper, cardboard, decaying leaves, or coir (coconut fiber). Glossy paper or magazines should not be used.  The bedding should be soaked for 5 to 10 minutes in a bucket of water and then should be wrung out. The bedding should be damp but not soaking wet. Worms should have 6 to 8 inches of bedding or at least half the depth of the worm bin.
3. Worms – It is not as simple as digging worms from a yard or garden. Out of the 9,000 worms only 7 species are known for use in vermicomposting. Of those, the Red Wiggler (Eisenia fetida) are the type of worm that is used most often with home composting systems. You can buy red wigglers from worm growers found online but be sure to shop around because prices do vary widely.  Once you receive the worms, worms should be placed on top of the bedding in the bin. The worms will immediately start to tunnel under the bedding to avoid the light. If you notice worms outside the bin, place the bin in a well-lit area for a couple of days to help the worms get acclimated to the bin.   
4. Food Scraps – After a few days worms should be ready to have some food scraps added to the bin. Items like vegetables, fruits, crushed eggshells, coffee grounds, shredded paper, shredded garden debris are acceptable. Meat items including fish should never be added to the bin. Other items that should not be added are pet/human manure, fat, citrus, tobacco, or onions and garlic. Once scrapes are added, cover them with 1 to 2 inches of bedding to prevent fruit flies.
   
   

Harvesting compost overtime is why you vermicompost to begin! It is the valuable mixture of earthworm castings and decomposed bedding and food scrapes that will help your plants thrive. There are several methods that are documented by Rhonda Sherman, Extension Solid Waste Specialist with North Carolina Extension:

1. Sideways Separation - To do this you feed the earthworms on only 1 side of the bin to harvest the vermicompost from the other side.
2. Light Separation - Empty all contents of the worm bin onto something like a plastic shower curtain in the light. Wait 5 minutes and scrape off the top layer of vermicompost. Continue to do this until you find the worms in clusters. Replace the left-over contents back in the bin. Be sure to add fresh bedding (6-8 inches) to the bin.
3. Vertical Separation – By feeding the worms in the upper bin the worms will migrate to where the food is, leaving the compost in the bottom bin to harvest.
   
   

With all methods of harvesting you will need to incorporate fresh bedding (6-8 inches) into the mix to ensure that the worms have enough to continue to “work” through. Once your mixture is harvested it can be used immediately or it can be stored for later use. It is best to incorporate it lightly with the preexisting soil in the vegetable garden or around trees and shrubs. Vermicompost can also be used as a top dressing for your lawn.
Sometimes worm bins may have issues that arise over time. It is important to note that your bin should not:

• smell bad (could be that the bin is too wet, or not enough air is moving through, or too many food scrapes have been added),
• attract flies (could be too much food has been added, or food scrapes have not been buried enough),
• have mold (could be that conditions are too acidic),
• have dry bedding (could be too much air is moving through the bin)
• have large numbers of worms dying/crawling out of the bin (could be too much food or too little food has been added, or the bin has been exposed to extreme temps, or the bin is too wet or too dry), or
• have lots of liquid in the bottom. This is called leachate and should not form in the bottom of the bin (could be too much food has been added or that there is poor ventilation or overwatering). It is important to note that leachate is not compost tea and should not be added to your garden.

Vermicomposting is a way to get earthworms to work for you and convert your organic waste into a valuable soil amendment that you can use in your garden! Over time you will learn to understand feeding, worm care and how to best harvest your compost.
