5 Striking Black and Yellow Snake Species to Keep an Eye On

The black and yellow snake boasts a bright, eye-catching appearance, and its colors serve a purpose beyond aesthetics. In nature, such vivid hues often act as warnings to deter potential predators.

However, not all black and yellow snakes are dangerous; some merely mimic the look. That said, it’s important to recognize which yellow and black snakes with red bands should be avoided (we’re looking at you, coral snakes).

Pro tip: A venomous snake often has a distinctive head shape. If you spot a triangular or spade-like head with a defined neck, it’s a sign the snake may be venomous.

1. Garter Snake

Garter snakes are found throughout North America, commonly in suburban gardens, near creeks, and by ponds. They are easily recognized by the two yellow stripes running along their dark-colored bodies.

These harmless snakes are excellent at controlling pests, as they feed on small creatures like amphibians, insects, and earthworms.

2. Mangrove Snake

Often referred to as the gold-ringed cat snake, this striking black and yellow serpent is not usually fatal to humans (though it can still inflict harm). The mangrove snake is mildly venomous and uses its toxins to capture prey like small birds and mammals. Found in the trees of Southeast Asia, it is an adept climber and skilled hunter.

3. Cat-eyed Snake

The cat-eyed snake is a nocturnal hunter, using its large, cat-like eyes to track down prey in the darkness. Juvenile cat-eyed snakes are more distinct with their black and yellow hues, while adults tend to have a more subdued dark brown color.

Native to Central and South America, the cat-eyed snake may seem intimidating, but it is only mildly venomous and does not present a serious danger to humans. It primarily preys on small amphibians and other cold-blooded animals, using its sharp night vision to its advantage.

4. Black Rat Snake

While this species leans more towards a "black and cream" appearance than strictly black and yellow, it still features a sleek black body, with some individuals displaying subtle yellow markings.

Though it isn't bright yellow or venomous, the black rat snake is a skilled predator. Known for keeping rodent populations in check, they often make homes in barns and fields, hunting mice and birds as their primary prey.

5. Pit Viper

The pit viper family includes some of the world’s most dangerous snakes, although not all of them are characterized by black and yellow patterns.

Pit vipers possess heat-sensing pits located between their eyes and nostrils, allowing them to detect warm-blooded prey even in complete darkness. With their highly venomous bites, these snakes are formidable hunters in the wild.

3 Snakes That Are Black, Yellow and Red

1. Coral Snake

Coral snakes are venomous and have a striking color pattern with yellow, red, and black rings. Their powerful neurotoxic venom is delivered through a bite, and they rely on ambush to capture their prey. The Texas coral snake, in particular, is one you’ll want to avoid, especially if you find yourself in the southern U.S.

2. Milk Snake

The milk snake features red, black, and white or yellow bands. Similar to the scarlet king snake, it is nonvenomous. The snake's name comes from an old myth that it would drink milk from cows.

These vibrant snakes primarily hunt small rodents and play a crucial role in controlling pest populations. The harmless milk snake exemplifies how some species can evolve to appear dangerous while posing no real threat.

3. Scarlet King Snake

The scarlet king snake is a nonvenomous species that closely resembles the coral snake, featuring a similar pattern of red, black, and yellow bands. Although harmless, its striking coloration helps it avoid predators. This snake relies on its appearance to stay safe while hunting small lizards and frogs as prey.
