Are black and white snakes venomous?
Black and white snakes don’t represent a species of snakes. Their coloring gathers them under a common physical trait.
Black and white snakes encompass members of various species that may or may not be venomous.
- Venomous – a small percentage of black and white snakes are venomous. Western Massasauga is some of the most dangerous black and white venomous snakes.
Their venom may not be fatal with the right medical treatment. However, people can die when bitten by this snake when there’s no medical treatment.
- Mildly venomous – many types of black and white snakes are mildly venomous.
The Puget Sound Gartersnake is one of the snakes with poisonous saliva which is now considered a mildly venomous species. This snake was considered not venomous just a few decades ago.
- Non-venomous – these types of snakes aren’t considered dangerous to people. They may still bite but without any health risks.
Black and white non-venomous species include the Speckled Kingsnake. This species is known for not having any venom but it resists the bites of multiple other venomous snakes including pit viper snake bites.
The non-venomous nature of black and white snakes doesn’t necessarily exclude the venomous nature. Some non-venomous black and white snakes are known to resist the bites of venomous snakes.
Furthermore, non-venomous black and white snakes can also eat juvenile venomous snakes.
Types of black and white snakes
1. Puget Sound Gartersnake
Scientific name: Thamnophis sirtalis pickeringii

The Puget Sound Gartersnake is a black species with either white, yellow, or blue narrow stripes.
This species is found in many habitats around the world as it has very good adaptability. Unlike many other species, the Puget Sound Gartersnake has changed its status from non-venomous to venomous.
Snakes of this species are now considered venomous.
They only produce mild venom which cannot harm people. However, this venom might still trigger allergic reactions.
Gums of this species are the toxic mouthparts as these snakes have no rear fangs.
This snake species is also known in the scientific world as the only snake species to resist tetrodotoxin, a powerful toxin in the animal world.
As a result, the snake can eat salamander species other snakes can’t. It eats Newt salamander frequently.
2. Gopher Snake

This is one of the largest black and white snakes in the US. It grows to a maximum size between 2.5 and 3.5 feet.
8. Speckled Kingsnake
Scientific name: Lampropeltis holbrooki

These snakes are known to use constriction against frogs and lizards.
They also exhibit defensive tactics against larger predators such as releasing a bad odor.
Snakes of this genus might also keep predators away using other techniques.
They can also expel feces to try and keep predators away. This is also a mimicking act where the snake plays dead.
9. Long-nosed Snake
Scientific name: Rhinocheilus lecontei
