Hunters and outdoors enthusiasts should be aware of a relatively new tick in Ohio, the black-legged “deer” tick, according to the Ohio Department of Health (ODH) in conjunction with the Ohio Department of Natural Resources’ (ODNR) Division of Wildlife. Black-legged ticks were once considered rare in Ohio, but the state now has likely established populations in 26 counties, most east of Interstate 71 where deciduous forests are present.
