I don't have kids, but I have dogs and I would not want them coming across any venomous snakes. However, I can't picture myself killing anything, so I'd just have to keep them out of the yard. I don't know what I'd do if it were inside my home, though.
I found a Boa once in the day care I used to run. I caught it & took it to the wildlife rescue right by my house. I lived with someone at the time who was terrified of snakes so I couldn't keep it.
