I voted NO.

I live in the burbs as well and it is uncommon to find anything other than a rat snake or garter around here but it is not unheard of. In fact, there have been rattlesnakes found in grant park in the city of chicago. Not to mention the cougar they killed in the city last year. (for no good reason might i add)

So no. Even if i did come across a venomous snake i would not try to kill it. I would avoid it but i would not hurt it. About the only thing i kill is rodents (humanely) for my snakes, & the occasional spider or house centipede if its in my house. Those things just CREEP ME OUT!
