Thank you for giving me the opportunity to answer your question regarding Kiaway Island, SC!
I would love to tell you that there are no snakes in Charleston SC area neighborhoods but I would not be telling you the truth! There are snakes everywhere along the coast just as there are in other parts of the state. But, that being said, I live just off of the marsh and across from a pond and I have never seen a snake in my yard. They may be there, but I have never seen them and I have lived in my home for almost 20 years. Like any other wildlife that you may encounter, if you give them their space, all will probably be ok.
I hope that this has been helpful! Please let me know if there is any other info that would be helpful to you...No obligation, of course!
