Introduction

Ohio is home to thousands of insect species, from harmless pollinators to invasive pests. Some are beneficial, like bees and butterflies, while others can damage property, plants, and even health.

For homeowners and businesses, knowing which bugs are common and which are new threats is key to protecting property, crops, and peace of mind. This guide highlights Ohio’s most common pests, the newest invasive insects, and what to do if you encounter them.

What Is the “New Bug” in Ohio? Spotlight on the Spotted Lanternfly

Emergence in Ohio

First detected in Pennsylvania in 2014, the spotted lanternfly quickly spread into neighboring states. It was confirmed in Ohio just a few years ago and has since become a major concern for agriculture and homeowners alike.

The insect is easy to recognize: striking gray wings with black spots, bright red underwings, and a strong hopping ability. Adult lanternflies congregate on tree trunks and outdoor structures, leaving sticky residues called “honeydew.”

Why It’s a Problem

The spotted lanternfly feeds on sap from more than 70 plant species. In Ohio, it threatens:

• Grapes and vineyards
  
• Fruit trees
  
• Hardwood trees and ornamental plants

Heavy infestations weaken plants, cause sooty mold, and harm both commercial and backyard growers.

Control Efforts

Ohio has shifted from eradication to managing and slowing the spread.

• Residents are urged to kill lanternflies on sight.
  
• Destroy egg masses (brown, mud-like patches laid on flat surfaces).
  
• Quarantine zones and inspections are in place across multiple counties.

Check vehicles, trailers, and firewood before moving them from infested areas.

What Is the Most Common Bug in Ohio? Everyday Pests Homeowners Encounter

Ohio’s Insect Diversity

Ohio’s ecosystems—forests, farmland, and urban areas—host thousands of insect species. While many are beneficial, several are consistent household and garden pests.

Common Indoor Pests

• Bed bugs – Hide in mattresses, couches, and crevices. Their itchy bites appear in clusters or lines.
  
• House flies – Spread bacteria on food and surfaces.
  
• German cockroaches – Thrive in kitchens, pantries, and basements, contaminating food and triggering allergies.

Seasonal Invaders

Some bugs flock to homes as the weather cools:

• Boxelder bugs – Black with red markings, congregate on sunny walls.
  
• Brown marmorated stink bugs – Give off an odor when crushed.
  
• Asian lady beetles – Similar to ladybugs but invade homes in fall to overwinter.

Widespread Tree Pests

The emerald ash borer (EAB) remains one of Ohio’s most destructive pests. Since its detection, it has killed tens of millions of ash trees across the Midwest. EAB larvae tunnel beneath bark, cutting off nutrients and water, ultimately killing the tree. Urban forests and shade trees continue to suffer its effects.

What’s the “New Insect Bug” Going Around?

Japanese Beetles

While not brand-new, Japanese beetles are becoming more active across Ohio during summer. Their metallic green heads and copper wings are unmistakable. Adults skeletonize leaves of roses, fruit trees, and turfgrass, while larvae (grubs) damage lawns underground.

Emerald Ash Borer

Still spreading and devastating ash trees statewide, the emerald ash borer remains a long-term ecological and economic threat. Even after years of outreach, homeowners should monitor their ash trees for signs of decline—thinning crowns, bark splits, and D-shaped exit holes.

What to Do If You See a Lanternfly in Ohio

Immediate Action Steps

• Kill the insect on sight.
• Scrape off and destroy egg masses. Place them in a sealed bag with rubbing alcohol or hand sanitizer.
• Reporting Sightings

Contact local authorities or the Ohio Department of Agriculture to report infestations. Accurate reporting helps track and slow the pest’s spread.

Prevention Around the Home

• Inspect outdoor furniture, tools, vehicles, and firewood before moving them.
• If living near a quarantine zone, follow all state guidelines for moving materials.

Keep trees pruned and monitor for honeydew or sooty mold—early signs of infestation.

Other Invasive Bugs in Ohio to Watch

Asian Longhorned Beetle

This black beetle with white spots attacks hardwoods such as maple, buckeye, and birch. Discovered in Ohio within the past decade, it remains under close monitoring.

Spongy Moth and Box Tree Moth

These invasive moths defoliate trees, weakening forests and ornamental plantings. Without control, they can spread quickly.

Northern Giant Hornet

Rare but concerning, this large hornet (sometimes called “murder hornet”) has drawn attention for its potential to harm honeybee populations. It has not established in Ohio but is on the radar of state officials.

Why This Matters for Homeowners and Businesses

Protecting Property

Pests can damage structures, landscaping, and crops. Termites and carpenter ants threaten wood. Lanternflies and Japanese beetles destroy ornamental plants.

Reducing Health Risks

Some bugs spread disease or trigger allergies. Cockroach allergens can worsen asthma; tick bites may transmit Lyme disease.
