Are Garter Snakes Poisonous? A Guide To Understanding These Common Critters

Garter snakes! Those slithering, striped visitors that pop up in backyards, gardens, or even near our business properties are a familiar sight for many.

But their sudden appearance can spark a question: Are garter snakes poisonous? You will come to realize that understanding these snakes is key to managing them safely.

Let us dive into the slithery truth! Have you spotted a garter snake recently? What caught your eye about it?

 

What Do Garter Snakes Look Like? (Identification)

Garter snakes (Thamnophis genus) are among North America’s most common snakes, found in gardens, forests, and urban areas.

They are slender, typically 18 to 55 inches long, with distinctive stripes (yellow, white, or red) running along their bodies.

Unlike venomous snakes like rattlesnakes, garter snakes lack triangular heads or vertical pupils, sporting rounded heads and circular eyes instead.

Quick Tip: Look for three longitudinal stripes on a slim body to confirm it is a garter snake. Have you noticed any striped snakes in your yard? Compare them to photos online for quick identification.

• Size: Usually under 4 feet, with females larger than males.

Are Garter Snakes Poisonous?

The burning question: Are garter snakes poisonous? The short answer is no; they are not poisonous or venomous in the way rattlesnakes or vipers are.

Garter snakes lack venom glands and do not produce toxins that pose significant harm to humans. However, they produce a mild neurotoxic saliva that can subdue small prey like frogs or worms.

This saliva is harmless to humans, causing no more than slight irritation if bitten, which is rare since garter snakes are non-aggressive.

 

What are the Bite Risks

• Likelihood: Bites are uncommon, as they bite only when threatened or handled.
• Symptoms: Mild redness or itching; no systemic effects. Clean bites with soap and water to prevent infection.
• Allergies: Less than 1% of people may have minor allergic reactions.

Quick Tip: If bitten, wash the area and monitor for swelling. Worried about snake bites in your area? Keep a first-aid kit handy for peace of mind.

 

What is the Behavior and Ecological Role of Garter Snakes?

Garter snakes are harmless helpers, feeding on pests like slugs, insects, and small rodents that damage gardens or crops.

They are active from spring to fall, often basking near water or hiding under rocks, and hibernate in winter. Their presence may indicate a healthy ecosystem, but it can startle those unprepared.

Behavior Highlights

• Activity: Diurnal, most active in warm weather (60–80°F).
• Habitat: Prefer moist areas.
• Defense: Release a musky odor when threatened, not venom, to deter predators.

Quick Tip: Have you spotted garter snakes near water sources? Check for debris piles or tall grass where they hide. Could clearing these spots reduce sightings?

 

How to Keep Garter Snakes At Bay (Control)

While garter snakes are not dangerous, you may want to manage their presence around your homes or businesses to avoid startling staff or customers. Here is how to coexist with or deter them humanely:

1. Modify The Environment

• Remove attractants like leaf piles, tall grass, or standing water, which draw garter snakes.
• Keep lawns mowed.
• Seal gaps under sheds or decks.

Quick Tip: Trim vegetation 6 inches from your structures to limit hiding spots. What is one area in your yard that could use a quick cleanup?

2. Use Barriers

• Install fine-mesh fencing (1/4-inch holes) around gardens or patios to block entry.
• For businesses, seal loading dock gaps to prevent access.

Quick Tip: Check fences monthly for holes or wear. Could a small barrier make your space less snake-friendly?

3. Relocate Safely

If garter snakes persist, relocate them humanely. Use gloves and a bucket to move them 1 to 2 miles away, as closer releases lead to higher return rates.

Check local laws, as some areas protect native snakes.

Quick Tip: Hire a wildlife professional for safe relocation, especially in commercial settings. Ever considered letting a pro handle your snake situation?

4. Monitor And Maintain

Regularly inspect for signs like shed skins or musky odors.

Quick Tip: Set a calendar reminder for seasonal inspections. What is one spot you could check today for snake activity?
