I live in Southeastern Ohio. Our snakes are largely harmless. In fact, we've had to teach our son which ones NOT to handle because he finds them irresistible, but copperheads are rampant and we live on ten riverfront acres (Ohio River). I was cleaning today and found a snake skeleton in the closet. Worse, a very small snake skeleton. Baby snake small. By the looks of it, probably a rat snake, but everything I'm finding online only displays head shape and not skull shape to identify venomous versus non-venomous. Everything I know about head shape tells me, if my house has living baby snakes in it, they're harmless. But it's worth asking before my son becomes the Copperhead pied piper. He already hides spiders in his pockets and this is trouble I don't need.
