I use to trap snakes for a hobby and research them. Most snakes in Louisiana are non poisonous. The only poisonous snakes are (In order from deadliest is – A. Coral Snake B. Rattle Snake/Cotton Mouth…. and least the copper head. I see these snakes everywhere and I’m 90 % sure it’s a Western Ribbon Snake…or it could be the Salt marsh snake or common garden snake.. Look at its head to the one on LA snakes, had a small dot. These snakes love gardens, and shaded areas. I like to have them around to kill bugs. Most people will not get close enough to ever tell, but if you can a snake, ONLY in Louisiana, and if it has a Cat’s Eye (slit) then it’s poisonous. If it has a DOT in its eye it is harmless. EXCEPT the Coral snake, it has a dot, but be careful because the Coral looks similar to a certain types of snakes such as the milk or king snake. The eaisest way to distinguish them from the coral is red on black then venom Lack, but red on yellow kill a fellow. Hope this helpsn
