Hope not!
Checked out Coral Snakes on Google. Oh my god don`t want ever get near one. The bites looks horrible.They are the most poison snakes in Texas?
I got bite once from a spider on my knee (don`t know what kind). My knee was red and swollen for over two weeks that was already pretty bad.
I think Coral snakes prefer a rocky or sandy soil. We are on black clay and have never had one

You are probably on sand in your area...? YIKES!
