These Snakes Might Surprise You, but They Are Completely Harmless.
Most people assume every snake they see is dangerous, but the reality is, plenty of backyard visitors are entirely harmless. Some of them even help keep pest populations in check, making your garden a healthier place. Knowing which snakes pose no threat can save you from unnecessary panic and help you appreciate the crucial role they play in the ecosystem.
These non-venomous snakes may look intimidating, but they are more interested in minding their own business than causing any trouble. If you spot one of these 12 species slithering through your yard, there’s no need to worry. Instead of fear, you might even feel lucky to have a natural pest controller on your property.
Garter snakes are common backyard visitors and excellent pest controllers.
One of the most frequently spotted snakes in gardens, garter snakes are completely harmless and even beneficial. According to American Kennel Club, they primarily feed on insects, slugs, and small rodents, making them a natural form of pest control. These snakes are typically brown, green, or yellow with signature stripes running down their bodies.
Garter snakes are adaptable and can thrive in a variety of environments, from grassy fields to urban backyards. They are often mistaken for venomous species due to their quick movements and defensive behaviors, but they pose no risk to humans or pets. If you see one, it’s best to leave it alone and let it continue keeping your garden free of unwanted critters. They are also resistant to certain toxins in amphibians, allowing them to prey on creatures that might be dangerous for other animals. They hibernate in large groups during winter, often returning to the same den year after year. Garter snakes rely on their keen sense of smell and heat-sensitive tongues to locate food.
Common kingsnakes help keep venomous snakes away.
Kingsnakes may look intimidating, but they are one of the best snakes to have around. As stated by Backyard Boss, these snakes feed on other snakes, including venomous ones like rattlesnakes, making them excellent protectors of your yard. They are dark brown or black with thin yellow or white bands, making them easy to recognize.
Unlike venomous species, kingsnakes kill their prey by constriction rather than venom. They are solitary creatures that avoid human contact, preferring to stay hidden under logs or in tall grass. If you happen to spot one, consider yourself lucky—these snakes play a critical role in keeping more dangerous species at bay. They are known for their immunity to rattlesnake venom, allowing them to hunt and kill rattlesnakes effectively. Kingsnakes are powerful constrictors, capable of subduing prey much larger than themselves. Their calm and non-aggressive nature makes them popular among reptile enthusiasts.
Milk snakes look like a dangerous species but are completely harmless.
Milk snakes often get mistaken for venomous coral snakes due to their bright red, yellow, and black banding, but they are entirely harmless. According to A-Z Animals, their striking coloration serves as a defense mechanism, scaring off predators that mistake them for something dangerous.
Despite their bold appearance, milk snakes are shy creatures that prefer to avoid confrontation. They feed on small rodents, making them a welcome presence in any backyard. If you see one slithering across your garden, there’s no need to panic—it’s just another natural exterminator at work. These snakes are excellent climbers, often found in barns or attics where they hunt for mice. They have a gentle temperament and rarely bite when handled. The name “milk snake” comes from an old myth that they drank milk from cows, though this has no basis in reality.
Green snakes blend in with nature and feed on insects.
With their emerald green coloration, green snakes are perfectly camouflaged in gardens and grassy areas. As noted by LSU Ag Center, these snakes primarily feed on insects and spiders, helping to control garden pests without the need for chemical pesticides.
There are two common types: the smooth green snake and the rough green snake, both of which are completely harmless to humans. They are slender and fast-moving, preferring to stay hidden among foliage rather than confront larger animals.

They are often active during the day, making them one of the more visible backyard snakes. Unlike many other snake species, they rarely bite when threatened.
Gopher snakes mimic rattlesnakes but are totally safe.
These large, non-venomous snakes have a habit of shaking their tails in dry leaves, making them sound like rattlesnakes. However, they are completely harmless and actually help control rodent populations. Gopher snakes, also called bullsnakes, have yellow or pale bodies with dark brown or black markings, which can sometimes make them appear more threatening than they really are.
These snakes rely on bluffing tactics to deter predators, which means they may hiss and strike if cornered. However, they lack venom and are not a danger to humans or pets. If left alone, they will continue playing their role as expert rodent hunters, keeping your yard free of unwanted pests. Gopher snakes are known for their ability to adapt to various environments, from deserts to grasslands. They often inhabit burrows made by other animals, using them as shelter.

Watersnakes are often misunderstood due to their defensive behavior when approached. While they may flatten their bodies and appear aggressive, they are more likely to flee than attack. If you have a pond or stream nearby, these snakes are simply part of the natural ecosystem. Plain-bellied watersnakes are highly adaptable and can be found in a variety of aquatic habitats. They are known for their ability to remain submerged for long periods while hunting for prey. During warmer months, they bask on rocks or logs near the water’s edge to regulate their body temperature.
Smooth earth snakes stay hidden underground.
A snake you might not even realize is living in your yard, the smooth earth snake prefers to stay hidden in loose soil, mulch, and leaf litter. These tiny, glossy gray or brown snakes are harmless to humans and specialize in hunting insects and earthworms.
Since they spend most of their time underground, encounters with smooth earth snakes are rare. If you do happen to see one, rest assured that it’s only interested in burrowing deeper into the soil to continue its work as a pest eliminator.

Worm snakes are harmless and spend most of their time underground, where they help aerate soil and control insect populations. Their diet primarily consists of soft-bodied insects such as earthworms, making them an essential part of the ecosystem.
Due to their reclusive nature, worm snakes are rarely seen above ground unless heavy rains force them to the surface. If you spot one, there’s no need for alarm—they pose no threat and will quickly disappear back into the soil where they feel most comfortable. They are highly adapted to life underground, using their pointed heads to navigate through compact soil. Their scales are smooth and shiny, helping them move easily through dirt. Because of their tiny size and non-aggressive nature, they are among the least threatening snake species to encounter.
