Which Garter Snakes are Venomous: A Guide to Understanding Dangerous Species

There is something eerie about snakes that often makes our skin crawl, but few people know that venomous snakes are only about 15% of all snakes, and even within this subset, not all types are created equal. In fact, there are garter snakes that are venomous, which is surprising considering how often we see them in the wild. Garter snakes are often dismissed as harmless garden snakes, but some of them can pack a punch with their venomous bite, which is something not many people know.

There are two species of garter snakes that pack venom in their bite: the Plains Garter Snake and the Short-Tailed Garter Snake. These two types of snakes have been known to cause discomfort, swelling, and itchiness in their victims. While not deadly to humans, their venom can be dangerous to small pets such as cats or dogs. Because of their harmless nature, these two species are often overlooked by people who underestimate their venomous potential.

It’s important to note that not all garter snakes are venomous, and even the Plains and Short-Tailed Garter Snakes are not universally venomous. Only some individuals within these species have venomous glands, which makes it even harder to differentiate them from their non-venomous counterparts. Knowing which snakes are venomous can be crucial when it comes to preventing accidents and injuries. With that in mind, it’s always best to approach any unknown snake with caution, whether it’s a garter snake or not.

Characteristics of Venomous Snakes

When it comes to venomous snakes, it is important to know what characteristics to look for in order to identify them and protect yourself from their deadly bites. Here are some key features to keep in mind:

  • Head shape: In general, venomous snakes have a triangular-shaped head, while non-venomous snakes have a more rounded head.
  • Fangs: All venomous snakes have hollow fangs that inject venom into their prey or predators. These fangs are located in the front of their upper jaw, while non-venomous snakes typically have solid teeth.
  • Pupils: Most venomous snakes have elliptical-shaped pupils, while non-venomous snakes typically have round pupils.
  • Coloration: While snakes can come in a variety of colors, many venomous snakes have bright or contrasting patterns to warn potential predators of their venomous status. However, some venomous snakes may also have more subdued colors to blend naturally into their environment.

It is important to note that while these characteristics can be helpful in identifying venomous snakes, they are not foolproof. Some non-venomous snakes may have triangular-shaped heads or elliptical pupils, while some venomous snakes may have round pupils or muted coloration. It is always best to err on the side of caution and assume a snake is venomous unless you are certain it is not.

How to identify venomous garter snakes

Garter snakes are one of the most common snakes found in North America. While they are generally harmless, some species of garter snakes are venomous. Here are some tips on how to identify venomous garter snakes:

  • Check the location: Venomous garter snakes are only found in certain regions. If you live in an area where venomous snakes are common, it’s important to learn how to identify them.
  • Look at the color: Venomous garter snakes have a distinctive coloration compared to non-venomous species. Most of them have a bright yellow or green stripe on their head and a black body.
  • Check the size: Venomous garter snakes tend to be larger than non-venomous species. They can grow up to two feet long.

It’s important to note that not all species of garter snakes are venomous. Some of the venomous species include:

Common Garter SnakeNorth America
Terrestrial Garter SnakeWestern United States
San Francisco Garter SnakeCalifornia, United States

If you come across a garter snake and are unsure if it is venomous, it’s best to leave it alone and call a professional for assistance.

Differences between venomous and non-venomous garter snakes

Garter snakes are commonly found in North America, and while they are generally harmless, some species are venomous. It’s important to understand the differences between venomous and non-venomous garter snakes to stay safe when encountering them in the wild.

  • Head Shape: Venomous garter snakes have a triangular-shaped head, while non-venomous garter snakes have a more rounded head.

Venomous Garter Snake Habitats

Although garter snakes are not typically known for their venomous bite, there are a few species that have venom glands and should be approached with caution. One important factor to consider when identifying venomous garter snakes is their habitat. Venomous garter snakes tend to live in specific types of environments and regions.

  • Prairies: The Plains garter snake (Thamnophis radix) is one species that can be found in prairies and grasslands of North America. These snakes have a venomous bite that is used to subdue their prey, which often includes small mammals and amphibians.
  • Wetlands: The Common garter snake (Thamnophis sirtalis) is a widespread species that can be found in wetlands and marshes throughout North America. While most populations of Common garter snakes are not venomous, there is a subspecies known as the Eastern ribbon snake (Thamnophis sauritus) that has a mildly venomous bite.
  • Deserts: The Western terrestrial garter snake (Thamnophis elegans) can be found in a variety of habitats, including deserts and grasslands of western North America. While this species is non-venomous, there is a subspecies known as the San Francisco garter snake (Thamnophis sirtalis tetrataenia) that has venomous saliva.

It’s important to note that while these species have venomous bites, they are not considered to be dangerous to humans. If you encounter any garter snake in the wild, it’s always best to give them space and observe them from a safe distance.

To summarize, venomous garter snakes can be found in a variety of habitats, including prairies, wetlands, and deserts. While these species may have venomous bites, they are generally not dangerous to humans and should be respected and observed from a safe distance.

The danger of venomous garter snake bites

Antivenom is available for the treatment of venomous garter snake bites, and can be life-saving if administered promptly.

It’s important to remember that most garter snakes are harmless and play an important role in controlling pest populations. However, if you encounter a garter snake in the wild, it’s best to keep your distance and avoid provoking it. If you do get bitten by a snake and suspect that it may be venomous, seek medical attention right away. Stay safe and be aware of the wildlife around you!

First aid for venomous snake bites

Being bitten by a venomous snake can be a terrifying and life-threatening experience. If you live in an area where venomous snakes are present, it is important to be prepared for a snake bite emergency. Here are some vital first-aid tips to follow if you or anyone around you gets bitten by a venomous snake:

  • Stay calm and still: The first thing you need to do if you get bitten by a venomous snake is to stay calm. Move as little as possible to decrease the spread of venom in your body. In most cases, snake venom takes time to take effect, usually ranging from a few minutes to several hours.
  • Call for help: Even if you think the snake is non-venomous, it’s always a good idea to get medical attention as soon as possible. Dial your local emergency number or ask someone to take you to the nearest hospital immediately.
  • Remove any tight clothing or jewelry: As swelling can occur quickly, remove any tight clothing or jewelry near the bite area before swelling develops. This is essential to prevent restriction of blood flow.

Here are some things you should not do:

  • Do not try to catch or kill the snake, as this will only put you at risk of being bitten again.
  • Do not apply a tourniquet or attempt to cut the bite area. This can worsen the situation and may lead to more damage to the affected area.
  • Do not attempt to suck out the venom, as this can introduce bacteria into the bite area and lead to infection.

Do remember, each venomous snake bite is different and the type of treatment needed will depend on the type of snake in question. However, following these general steps as first aid will help alleviate the pain and lessen the severity of the condition.

Venomous snake bite first aid kit

To be better prepared for snake bites, you can create a venomous snake bite first aid kit. One could include:

  • A compression bandage to immobilize the affected arm or leg
  • Antiseptic to clean the wound
  • Ibuprofen or paracetamol to alleviate pain and reduce swelling. However, do not use aspirin or any other related compounds, which may lead to further bleeding if bleeding occurs.
  • A snakebite extractor: A suction device that helps to extract the venom from the bite area.

How antivenom works

Antivenom is a vital tool for treating venomous snake bites. It contains antibodies that can neutralize the venom in the bitten person’s body. These antibodies are harvested from animals such as horses or sheep that have been exposed to venom from the targeted snakes, which triggers their immune systems to produce the antibodies. The antivenom is created using the harvested antibodies from these animals and injected into the bitten person to alleviate the venom’s effects.

Treatments for venomous snake bites:

Snake typeSymptomsTreatment
RattlesnakesBleeding, severe pain, nausea, rapid heart rateAntivenom, pain relief, hydration
Cottonmouths/water moccasinsPain, swelling, tissue damage, seizures, low blood pressureAntivenom, pain relief, hydration
CopperheadsPain, swelling, redness, necrosis, itchy rashNo antivenom, pain relief, hydration

Do note: These treatments are general in nature and may vary depending on the severity of the snake bite and individual circumstances.

Conservation efforts for venomous garter snakes

While garter snakes are generally known as harmless creatures, it is important to note that some species are venomous. There are only two types of venomous garter snakes in North America: the Eastern and Western varieties of the common garter snake.

Conservation efforts for venomous garter snakes are vital to ensure their preservation. As with other venomous animals, people often resort to killing them out of fear and lack of knowledge about their behavior. This can be detrimental to garter snake populations, especially those that are already at risk due to habitat loss and fragmentation.

  • Education and awareness programs: These initiatives aim to teach people about the importance of garter snakes in the ecosystem and how to differentiate between venomous and non-venomous snake species. They help to dispel common myths and misconceptions and encourage people to be more tolerant and accepting of these creatures.
  • Habitat restoration and protection: As mentioned earlier, habitat loss and fragmentation are significant threats to garter snakes. Conservation efforts involve restoring and protecting their habitats to ensure their long-term survival. Efforts include reforestation, wetland restoration, and invasive species removal.
  • Research and monitoring: Research is conducted to better understand the behavior and ecology of venomous garter snakes. This data is used to create effective conservation strategies and help track the population status of these species.

Overall, conservation efforts for venomous garter snakes are crucial to ensure their survival. While they may not be as well-known as other endangered species, they play a vital role in maintaining the balance of the ecosystem. As such, it is important that we continue to work towards their preservation.
