Ticks are small arachnids that play a significant role in Ohio’s ecosystems, though they are often best known for their ability to transmit diseases. One of the most common species is a tick frequently found on pets and wildlife, especially in grassy or brushy areas. Another widespread species is a tick that thrives in kennels and homes, capable of completing its entire life cycle indoors.
Ohio is also home to a species associated with Lyme disease, which has expanded its range across the state in recent years. In southern and central Ohio, a tick with a distinctive white spot has become increasingly common. In colder regions, wildlife may host a species that primarily affects large mammals.
While ticks can pose risks to humans and animals, understanding their habitats and behavior helps reduce encounters and supports safe outdoor recreation.
