They aren't really a problem around here. We have a few timber rattlers around Lake Geode. Have witnessed a couple big ones. There are a couple caves they winter in.
Before I was married......helped out my future father-in-law at his business, after his back injury. Every random snake alongside the road, we had to stop and do a power stall. Felt kinda bad.
The big black snakes here are no problem. They're pretty passive, eating lots of mice (and maybe a few chicken eggs). You'll see them in the trees, breeding season, wrapped around each other.
We had a regular black in the chicken coop, years ago. Chickens didn't care. Wife put golf balls in a nest....enticing a hen that wanted to sit. Went down to feed the chickens and that black snake ate one of the golf balls. Disappeared after that, hope it survived.
Reaching into a bag of cracked corn with a black snake in it....will wake you up better than 3 cups of espresso. Assume they feed on the mice getting into the corn.
Snakes are OK......excluding African.
