The simplest answer to whether yellow rat snakes are poisonous is a big No. They do not carry any venom, and neither does the danger. Turns out, if you ever come across one in your garden or while heading off to work, you can relax because they really are not a big threat to you and could not risk any sort of major medical risk to people and pets (including cats & dogs).
They are commonly found in the southeastern US and are pretty well-known for their yellow-to-olive color and expert climbing abilities. Yes, you heard that right, they can climb up to 60 feet high in trees to hunt birds, eggs, and squirrels, and therefore are often considered semi-arboreal.
Their bite could, however, give you a minor scratch or pain, and the worst part could be that you end up being bacterially infected since their mouth and skin contain microorganisms and germs.

Are Yellow Rat Snakes Poisonous or Venomous?
It is common for people to use the words poisonous and venomous as if they mean the same thing, but in the world of biology, they are very different. If something is poisonous, it means it is dangerous if you eat it or touch it.
If something is venomous, it injects a toxin through a bite or a sting. Even with that distinction, the yellow rat snake poisonous or not debate is easy to settle because they are neither. They do not have fangs designed to deliver venom, and they are not toxic to touch.
Instead of using venom to kill their prey, these snakes are constrictors. They grab a meal with their mouths and then quickly wrap their muscular bodies around it to suffocate it. This is a very efficient way of hunting birds and rodents, but it is not a technique they use on humans.
Since they lack any biological “chemical weapons,” you really do not have to worry about the yellow rat snake poisonous or not question whenever you see one near your home. They are simply large, powerful, and harmless to us.
Do Yellow Rat Snakes Bite Humans?
Just because a snake is not venomous does not mean it cannot bite. Like any animal with a mouth, a yellow rat snake will bite if it feels it is about to be harmed or killed. However, they are generally very shy and would much rather glide away into the grass than start a fight with a giant human. Most bites happen when someone tries to pick the snake up or accidentally steps on it.
If you do happen to get bitten, it might sting a little and bleed slightly, much like a scratch from a briar patch or a grumpy house cat. They have rows of small, sharp teeth rather than long fangs. Because they are not toxic, the main concern with a bite is just keeping the area clean to avoid a minor infection. To settle the worry for good, regarding the yellow rat snake are they poisonous, the answer remains a firm no, even if they decide to give you a defensive nip.
Are Yellow Rat Snakes Dangerous?
In the grand scheme of things, these snakes are not dangerous to humans or large pets like dogs and cats. They are quite docile by nature. When they feel threatened, their first move is usually to “freeze” and hope you do not see them. If that fails, they might shake their tail in dry leaves to mimic a rattlesnake or release a smelly musk to discourage you from sticking around.
The only things that truly need to fear a yellow rat snake are small animals. They are incredible hunters of rats, mice, and even small birds. If you have a chicken coop, you might want to keep an eye out, as they are notorious for stealing eggs. But as far as physical danger to a person goes, they are about as harmless as a wild animal can be. You are in no danger of being poisoned or seriously injured by one of these golden climbers.
How to Identify a Yellow Rat Snake
Identifying these snakes is fairly straightforward once you know what to look for.
- They are usually a distinct dull yellow or greenish-yellow colour with four dark longitudinal stripes running down the length of their bodies.
- As they get older, these stripes become more prominent.
- They are quite long and can easily reach lengths of five to seven feet, though they stay relatively slender.
- Their heads are slightly wider than their necks, giving them a bit of a “turtle” look from certain angles, and their eyes have round pupils. This is a key detail, as many venomous snakes in the same regions have vertical, cat-like pupils.
- Their scales have a slight ridge on them, which makes them feel a bit rough to the touch rather than smooth and shiny.
- If you see a long, striped, yellow snake in a tree or near a barn, you can be fairly certain it is a rat snake.
