Virginia Snake Season: When They Come Out, Peak Months, and How to Stay Safe

Most people are surprised to learn that snakes can appear in Virginia as early as March — and in some cases, even on a warm winter afternoon. If you spend time outdoors, work in a garden, or simply want to know when to be more watchful on the trail, understanding Virginia’s snake season gives you a clear, calm advantage.

Virginia is home to 32 species of snakes, the vast majority of which are completely harmless and play a vital role in controlling rodent and insect populations. Knowing when these animals are active — and where they tend to show up — helps you share the landscape with them safely and confidently.

When Snake Season Starts and Ends in Virginia

Snake season in Virginia officially begins in spring, usually around March or April, and runs through late fall. The end of the season is not a fixed date on the calendar — it depends heavily on temperature and location across the state.

Snakes are most active from March to October, when the weather is warmest, and most come out of brumation — the reptile equivalent of hibernation — in March. Snakes prefer weather between 70 and 90 degrees Fahrenheit, and any warm day after March can trigger them to become more active.

Most snakes head back into brumation around October. Because snakes are cold-blooded and need to conserve energy when it gets cold, most snakes in Virginia begin their brumation in October. Once hidden away, they will remain dormant until March or April, depending on the weather.

Key Insight: Brumation is not the same as deep hibernation. Snakes can emerge from brumation to warm up or rehydrate, and on certain warm winter days, they are known to sun themselves briefly before returning underground.

Snakes generally become less active when temperatures dip below 60 degrees Fahrenheit. That said, the spate of bites usually ends by late October when it gets colder and snakes hibernate — though bites have been recorded as late as December on unusually warm days.

Peak Snake Activity Months in Virginia

While snakes can technically be encountered any month of the year during a warm spell, certain months bring noticeably higher activity levels. Understanding the rhythm of the season helps you know exactly when to be most alert.

Spring (March–May): Every year around early- to mid-spring, snakes begin to venture out of their hibernacula in search of food, mates, and shelter. This is when you’ll see the first snakes of the year basking on rocks, road edges, and sunny patches of ground to warm their bodies after months of dormancy.

Summer (June–August): Activity is high throughout summer, but the hottest weeks can push snakes into cooler, shadier spots during the day. Copperheads, for example, change the time of day they are active depending on the season — coming out at night during the hot summer months, but preferring daytime activity in spring and fall. From mid-July through September, Virginia typically sees an increase in rattlesnake movement, as this is their mating season and males are on the move searching for mates — the period when most human-rattlesnake encounters occur.

Fall (September–October): While people are busy enjoying fall foliage, snakes are busy looking for winter shelters and fattening themselves up before brumation. If you notice more snakes in early fall, it’s because they’ve been working overtime in search of food sources and winter burrows.

Pro Tip: Snakes typically prefer temperatures in the 80s Fahrenheit. If it gets too hot, they move to cooler places; if it gets too cold, they hunker down in denser, sheltered areas. Plan your outdoor activities with that temperature range in mind, especially during summer evenings.

Late Fall/Winter (November–February): Snakes are typically burrowed away from October to March. While you are unlikely to encounter one during this period, it is not impossible on an unseasonably warm day — especially in the southern parts of the state.

Common Snake Species in Virginia and Their Active Seasons

Virginia has 32 native species of snakes, yet only three have venom that is dangerous to humans. The rest are nonvenomous, harmless to people, and genuinely beneficial to have around. Here is a look at the species you are most likely to encounter and when they tend to be active.

Species	Active Season	Habitat	Venomous?
Eastern Rat Snake (Black Snake)	April–October	Forests, fields, barns, suburban areas	No
Eastern Garter Snake	March–October	Meadows, yards, near water	No
Northern Water Snake	April–October	Rivers, lakes, ponds, streams	No
Eastern Kingsnake	April–October	Forests, fields, near homes	No
Black Racer	April–October	Grassy fields, forest edges, near water	No
Eastern Copperhead	March–October	Forests, rocky areas, woodpiles, gardens	Yes
Timber Rattlesnake	April–October	Mountain forests, rocky ridges	Yes
Northern Cottonmouth	April–October	Swamps, marshes, streams (SE Virginia)	Yes

The Eastern Rat Snake — more commonly known as the Black Rat Snake — is Virginia’s longest native snake, capable of reaching up to 8 feet in length. It is one of the most commonly encountered snakes on the East Coast and can regularly be found in close proximity to humans and their homes. Despite their size, Eastern Rat Snakes are very docile and will typically flee at the first chance when encountering people.

The Eastern Garter Snake is the official state snake of Virginia and one of the earliest to emerge in spring. It is typically the species people come across most often. They are well-adapted to living around people and can often be found in city parks, farmland, cemeteries, and suburban lawns and gardens, preferring grassy environments near freshwater sources such as ponds, lakes, ditches, and streams.

Eastern Kingsnakes are known for eating other snakes, including venomous ones — making them a valuable presence in any yard or garden. You can learn more about what kingsnakes eat and why they are considered one of the most beneficial snakes in the region.

Important Note: The most commonly misidentified juvenile snakes are Eastern Rat Snakes and Northern Black Racers, which do not take on their characteristic solid black appearance until they begin to mature as adults. Young patterned snakes are frequently mistaken for copperheads — always observe from a safe distance before drawing conclusions.

The Black Racer is a shiny, all-black snake often found in grassy fields and areas close to lakes and rivers. It is active only during the day and is known for its frequent movement to evade predators. If you are curious about the different types of garter snakes found across North America, Virginia’s Eastern Garter Snake is one of the most widespread and recognizable.

Venomous Snakes in Virginia and When to Watch For Them

Only three of Virginia’s snakes are venomous: the Eastern Copperhead, the Northern Cottonmouth, and the Timber Rattlesnake. Understanding where each one lives and when it is most active is the most practical safety knowledge you can have. If you have ever wondered whether coral snakes are found in Virginia, the answer is no — the state’s venomous species are limited to these three pit vipers.

Eastern Copperhead

The copperhead, found statewide, is the most common venomous snake in Virginia; while it is usually not found inside homes, it may be common in gardens and woodlots. Copperheads are found in hardwood and mixed forests, pine woods, abandoned fields, high ground in swamps and marshes, suburban woodlots, ravines along creeks, upland rocky areas, rock walls, and woodpiles.

Copperhead bites to humans and pets are most often reported between May and October. You are more likely to see them active during the day in spring and fall when the weather is cooler. During the middle of summer, Eastern Copperheads are often nocturnal. Their distinctive hourglass-patterned body provides excellent camouflage in leaf litter — a key reason accidental encounters happen.

Timber Rattlesnake

Timber Rattlesnakes are mostly found in the mountainous region on the western side of Virginia. There is also a population in southeastern Virginia, where they are known as canebrake rattlesnakes. They prefer upland forests with ledges facing south in the spring and fall, and open woods and grass fields in the summertime.

From mid-July through September, Virginia sees an increase in rattlesnake movement as this is their mating season and males are on the move searching for mates. A single Timber Rattlesnake may indirectly remove 2,000–2,500 ticks annually from the wild through the rodents it eats — a remarkable ecological benefit that underscores why these snakes deserve respect rather than fear.

Northern Cottonmouth (Water Moccasin)

The most notable thing about the Northern Cottonmouth in Virginia is its very limited distribution within the state. In recorded Virginia history, the venomous cottonmouth has only been found in a specific set of southeastern counties and cities. Cottonmouths are semiaquatic, found in swamps, marshes, streams, and rivers, and like to bask on the shoreline close to wet areas. They are sometimes referred to as Water Moccasins.

While cottonmouths are venomous, they are placid snakes that only bite if stepped on or otherwise threatened. If you see a cottonmouth, leave it alone and rest assured it will do its best to avoid you. They are often confused for harmless Northern Water Snakes, which are frequently found in the rivers and streams of Northern Virginia and throughout the state.

Common Mistake: Many people misidentify nonvenomous Northern Water Snakes as cottonmouths. Non-venomous snakes will often flare their heads into a triangular shape to mimic venomous species — so head shape alone is not a reliable identifier. If you are unsure, keep your distance and do not attempt to handle the snake. You can also review the difference between venomous and poisonous snakes to better understand how venom works.

Over the past 30 years in Virginia, only 15 deaths have been attributed to venomous snake bite, and many of those victims did not seek medical attention. The risk is real but manageable with awareness and calm behavior.

Where Snakes Are Most Commonly Found in Virginia

Snakes are distributed across every region of Virginia, from the Blue Ridge Mountains to the Coastal Plain. Knowing the environments they favor helps you stay prepared wherever you spend time outdoors.

• Wooded areas and forest edges: Eastern Rat Snakes are often seen climbing trees or basking in sunny areas near woods and fields, with a solid black body and white underbelly as adults. Forested zones are prime habitat for copperheads as well.
• Rocky outcroppings and hillsides: Copperheads can be found throughout the state in forests and upland rocky areas, alongside streams, in rock walls and wood stacks, and other locations.
• Near water: Banks of streams, rivers, and lakes are common locations to find snakes. The Northern Water Snake in particular thrives in any freshwater habitat and is one of the most frequently spotted species near Virginia’s rivers and ponds.
• Yards, gardens, and woodpiles: Snakes like woodpiles because the temperature is fairly stable and it is easy for them to get into them — and numerous bites have occurred after people were taking wood out of a wood pile.
• Suburban and urban green spaces: Garter snakes are the species people come across most often, and they are well-adapted to living around people — commonly found in city parks, farmland, cemeteries, and suburban lawns and gardens.
• Swamps and wetlands: The Great Dismal Swamp area attracts a large number of snake species, including Northern Water Snakes, copperheads, and cottonmouths.

Keeping your yard mowed and free of brush and debris piles will deter snakes from inhabiting your yard. Bird feeders also attract snakes indirectly — birdseed dropped to the ground attracts rodents, which in turn attracts snakes. Eliminating food sources and shelter is the most effective long-term deterrent.

Pro Tip: Snakes may warm themselves along the side of blacktop roads, get into garages, or get under the covers of grills and outdoor equipment. They like places where they can shelter and be protected. Always check these spots before reaching in, especially during the active season.

What to Do If You Encounter a Snake in Virginia

Encountering a snake — whether on a trail, in your yard, or near your home — can feel startling. The good news is that snakes do not chase people. A snake has no reason to chase you, since you are much too big to be prey — to a snake, you are only considered a predator. Staying calm and giving the snake space is almost always the right response.

If You See a Snake Outdoors

1. Stop and observe from a distance. Snakes are not aggressive animals and will only defend themselves if provoked. They will usually stay put or retreat if given space.
2. Do not attempt to handle or identify it up close. Admire from a distance and do not try to handle the snake if you do not know what it is.
3. Give it a wide berth and move away calmly. If a snake appears to be heading toward you, it may simply be trying to reach its hiding spot and may not realize you are there. Simply move out of its way, and there will be no problem.
4. On trails, use a walking stick. When hiking poles or a walking stick hit the ground, they cause vibrations that alert snakes to your presence, letting them know you are in the area so they can stay out of your way.

If You Find a Snake in Your Home or Yard

1. Identify it safely, if possible. If a snake is found in the house, try to identify it. Once it is known to be non-venomous, carefully place a bucket or wastebasket over the snake, then slip a board under the container and carry the snake outside to release it.
2. Do not kill it. It is illegal to kill a snake in Virginia unless it is threatening you or your animals or makes its way inside your home. Even venomous snakes would rather flee than bite. Using venom for defense is a last resort — while it may save their life, they are effectively wasting their venom on something they cannot eat.
3. Call a professional for venomous species. If you find a venomous snake in your yard, do not try to move or kill it. Call a humane professional wildlife removal company with venomous snake experience, or simply let it go on its way if children and pets are not present.
4. Seal up entry points. If you have not sealed holes in the foundation, a snake may return. Have your home checked for rodent problems — if you eliminate the food source, the snakes will go elsewhere.

If You Are Bitten by a Snake

• Stay calm and move away from the snake immediately.
• Do not attempt to suck out venom, cut the wound, or apply a tourniquet.
• Remove any tight clothing or jewelry near the bite site in case of swelling.
• Call 911 or go to the nearest emergency room immediately, even if you are unsure whether the snake was venomous.
• Try to note the snake’s appearance (color, pattern, size) to assist medical personnel — but do not approach it again.

Important Note: Virginia Wildlife Management and Control operates a 24/7 snake identification hotline. You can text a picture of a snake to (804) 617-7086, and they will identify whether the snake is venomous or non-venomous. This is a useful resource if you are unsure what you are dealing with.

Virginia’s snakes are a natural and important part of the state’s ecosystem. They are extremely important for controlling various pests — many of the larger snakes eat mice, rats, moles, voles, and other small mammal pests, while smaller snakes eat plenty of bugs, slugs, and other very small pests. With a little knowledge and a calm approach, you can share the landscape with these animals safely all season long.
