Venomous (Poisonous) Snakes in Maryland

There are about 27 species and subspecies of snakes inhabiting Maryland’s diverse landscapes.

Nonetheless, the snake population in the state should hardly give anyone anything to worry about – as they are mostly harmless to humans. There are only two indigenous snakes to look out for when you’re in Maryland: Copperheads and Timber rattlesnakes.

Timber Rattlesnake (Crotalus horridus)

Also called canebrake rattlesnake or banded rattlesnake, the timber rattlesnake is a venomous pit viper endemic to eastern North America. It is the only snake in Maryland with a rattle and the only rattlesnake species in most of the populous Northeastern United States.

Its venom is highly toxic, containing neurotoxins that affect the brain and myotoxins, which cause muscle necrosis. Whether coiled or stretched out, rattlesnakes can quickly and accurately strike one-third or more of their body length from any position!

Copperhead (Agkistrodon contortrix)

A copperhead is a heavy-bodied snake measuring between 20 and 36 inches long. It has a coppery-red to a tan head and brown hourglass-shaped crossbands on its tan to dark brown back.
