Residents across southern Ohio, including Ross County and neighboring areas, are facing heightened risks from ticks as populations of key species expand and associated health issues rise. The lone star tick stands out for its connection to alpha-gal syndrome (AGS), a potentially serious allergy to red meat, while blacklegged ticks drive increasing Lyme disease reports.
Understanding the Ticks and Health Impacts
The lone star tick (Amblyomma americanum), identifiable by a white spot on the female’s back, is common in Ohio, particularly in southern regions. Its bite can transmit a sugar molecule called alpha-gal, triggering alpha-gal syndrome in some people. This leads to delayed allergic reactions—often 3 to 6 hours after consumption—to red meat such as beef, pork, or lamb, and sometimes to dairy or other mammalian products. Symptoms range from hives and itching to severe gastrointestinal distress or anaphylaxis.
Not every lone star tick bite causes AGS, and the exact reasons why some individuals develop it remain unclear. The Centers for Disease Control and Prevention (CDC) estimates hundreds of thousands of suspected cases nationwide since the early 2010s, with concentrations in areas where lone star ticks are established, including parts of the Midwest. Cases have risen alongside the tick’s expanding range.
Lyme disease, transmitted primarily by blacklegged ticks (also called deer ticks), presents different but serious concerns. Symptoms can include fever, fatigue, headache, and a characteristic bull’s-eye rash, potentially leading to long-term issues if untreated. Ohio has seen sharp increases: reported cases rose from 554 in 2022 to 1,788 in 2024, with continued elevation into 2025. Eastern and southern counties, including those around Ross County, are noted hotspots due to expanding blacklegged tick populations in wooded habitats.
The American dog tick is also widespread but primarily linked to other illnesses like Rocky Mountain spotted fever. All three main species—lone star, blacklegged, and American dog—are active in Ohio, with peak seasons from spring through fall.
Trends in Southern Ohio
In southern Ohio, including Ross County, lone star ticks thrive in shrubby and wooded edges, while blacklegged ticks favor forested areas. Local health authorities report these species as the most commonly encountered by people and pets. Lyme disease cases have increased notably in the region, mirroring statewide trends driven by tick population growth and habitat expansion.
Public health officials in Ross County and adjacent counties emphasize awareness as outdoor activities rise in warmer months. Tick encounters can occur in yards, parks, or trails, not just remote wilderness.
Prevention Strategies: What Works Best
Prevention remains the most effective defense, according to the CDC and Ohio Department of Health. No method offers 100 percent protection, but combining approaches significantly reduces risk.
• Repellents and Clothing: Use EPA-registered repellents containing DEET, picaridin, or oil of lemon eucalyptus on exposed skin. Treat clothing, boots, and gear with 0.5 percent permethrin, which remains effective through multiple washings. Wear long sleeves, long pants tucked into socks, and light-colored clothing for better visibility.
• Tick Checks and Hygiene: Shower within two hours of coming indoors. Conduct thorough checks on yourself, children, and pets. Tumble dry clothes on high heat for at least 10 minutes to kill any ticks. Remove attached ticks promptly with fine-tipped tweezers, grasping close to the skin and pulling steadily upward.
• Yard and Property Management: Keep grass short, clear leaf litter and brush, and create barriers like wood chips or gravel between wooded areas and lawns. Avoid placing play equipment or seating near wooded edges. Some residents explore backyard chickens or guinea fowl, which eat ticks, though results vary and birds require proper care. Certain plants like lavender or garlic may offer minor repellent effects but are not primary solutions.
• Pets and Professional Help: Use veterinarian-approved tick preventives on dogs and cats. Consider professional pesticide applications for yards in high-risk areas, following label instructions.
Stay Informed and Vigilant
If you develop symptoms after a tick bite or notice unusual reactions to red meat, consult a healthcare provider. Testing is available for both Lyme disease and alpha-gal syndrome. Early detection improves outcomes.
Ohio health departments, including in Ross County, provide resources for tick identification and reporting. As tick ranges expand with environmental changes, ongoing vigilance supports community safety across southern Ohio.
