When Do Snakes Come Out in Arkansas? Season, Species & Safety Tips

Arkansas is home to nearly 40 species of snakes, and if you spend time outdoors in the Natural State, chances are you will eventually cross paths with one. Snakes serve an important role in the environment, preying on rodents, insects, toads, frogs, crayfish, minnows, and other snakes. Most are completely harmless — but knowing when snakes come out in Arkansas, which ones to watch for, and how to respond if you see one can make all the difference.

Understanding snake activity patterns helps you stay calm and prepared rather than caught off guard. Whether you are hiking the Ozarks, gardening in your backyard, or fishing along a riverbank, this guide covers everything you need to know about Arkansas snake season from start to finish.

Key Insight: The majority of snakes you encounter in Arkansas are nonvenomous and beneficial to the ecosystem. Only 6 of the state’s roughly 39 native species are venomous.

When Snake Season Starts and Ends in Arkansas

Snake season in Arkansas does not follow a strict calendar — it follows the thermometer. Snakes can’t regulate their body temperature like warm-blooded creatures since they are cold-blooded. That means their activity levels rise and fall directly with outdoor temperatures.

Snakes will begin to come out when the temperature outside has reached 60 degrees. In Arkansas, that threshold is typically crossed in late February or early March, depending on the year. By the time spring is in full swing, snake sightings increase noticeably across the state.

On the other end of the season, brumation can occur between September and December, lasting until March or April. During brumation — a reptilian form of dormancy — snakes slow their metabolism and retreat to sheltered spots rather than fully shutting down like true hibernators.

Contrary to popular belief, snakes in Arkansas don’t hibernate all winter. Many of the state’s snake species enter a state of brumation, a reptilian form of hibernation where snakes become less active, seeking refuge in underground burrows or rock crevices to escape the winter chill.

This also means you should not assume snakes are completely absent in winter. It is possible to see snakes, including venomous snakes, all winter, especially on warmer days. A sunny afternoon in January can draw a snake out to bask, so year-round awareness is always a good habit.

Important Note: In Arkansas, it is illegal to kill any snake according to the Arkansas Game and Fish Commission. The only reason to break the law is if the snake “poses a reasonable threat or endangerment to persons or property.”

Peak Snake Activity Months in Arkansas

In Arkansas, snakes will be most active during spring, summer, and fall and less active during the winter. But within that broad window, activity shifts significantly by season and even by time of day.

The rule of thumb in North America is that snakes are most active from April to October and hibernate during the cold months outside of that range. In Arkansas, the warm climate means activity often begins a little earlier and lingers a little later than in northern states.

Here is how activity typically breaks down by season:

• Spring (March–May): With the arrival of spring warmth, a snake’s body temperature rises, leading them to become more active. “Typically they have not eaten in a while, so they are moving around actively seeking food,” according to wildlife extension specialist Professor Rebecca McPeake of the University of Arkansas. This is one of the most active periods of the year.
• Summer (June–August): During the hot summer months, snakes are more active at night and seek cooler shelter during the day. You are more likely to encounter them at dawn, dusk, or after dark.
• Fall (September–October): As temperatures cool, snakes shift back to daytime activity, feeding heavily before brumation. This can make fall another high-encounter period.
• Winter (November–February): Activity is minimal but not zero. Warm spells can bring snakes out unexpectedly. Snakes sometimes come out of their shelters to bask in the sunlight during brumation.

Time of day matters just as much as the season. While snakes can and will be active at any time of the day, most snakes in Arkansas are more actively hunting food at sunset and sunrise. During peak summer heat, in the summer they are most active at night, in the spring and fall or on cool days they seek patches of sunlight.

Pro Tip: Snakes are most active whenever temperatures are between 80–90°F. This means that snakes may be active most of the day during the spring, and during the early mornings and late afternoons throughout the summer.

Common Snake Species in Arkansas and Their Active Seasons

Arkansas is home to 39 snake species from 24 genera across 5 families. The vast majority of these are nonvenomous and play a vital role in controlling rodent and insect populations. Here is a look at some of the species you are most likely to encounter, along with links to help you learn more about the types of snakes in Arkansas.

Species	Type	Active Season	Habitat
Eastern Copperhead	Venomous	March–October	Forests, rocky hillsides, suburban areas
Northern Cottonmouth	Venomous	March–October	Rivers, swamps, ponds, drainage ditches
Timber Rattlesnake	Venomous	April–October	Dense forests, rocky outcrops, Ozark/Ouachita mountains
Western Rat Snake	Nonvenomous	April–October	Forests, farms, rocky terrain near fields
Common Garter Snake	Nonvenomous	March–October	Gardens, fields, pond edges, marshes
Prairie Kingsnake	Nonvenomous	April–October	Open fields, rocky hillsides, farmland
Northern Water Snake	Nonvenomous	April–October	Lakes, rivers, streams, wetlands
Eastern Hognose Snake	Nonvenomous	March–October	Sandy soils, open woodlands, fields
Milk Snake	Nonvenomous	April–October	Grasslands, forests, farmland, rocky areas

Several nonvenomous species are frequently seen near homes. Four species are often found near homes: the Common Garter snake, Eastern Milk snake, Gray Rat snake, and Northern Water snake. If you spot a striped snake in your yard, it is often a garter snake — you can explore snakes with stripes in Arkansas to help with identification.

Some of the most common nonvenomous snakes include Rat Snakes — excellent climbers and great at keeping rodent populations in check — Garter Snakes frequently seen in gardens and fields, Milk Snakes often mistaken for coral snakes, and Water Snakes frequently confused with cottonmouths but beneficial for the ecosystem.

One important distinction worth knowing: non-venomous snakes like to copy the color patterns or even the behavior of venomous snakes to scare away predators. This mimicry is a survival strategy, not a sign of danger. If you want to understand the difference between venomous and poisonous snakes, that distinction matters too — snakes are venomous, not poisonous. Kingsnakes are particularly fascinating because kingsnakes eat other snakes, including venomous ones, making them a natural form of pest control.

Pro Tip: Western diamondback rattlesnakes are active from April through October, even at night. You can find them in the Ouachita Mountains and southwestern Ozark highlands of Arkansas.

Venomous Snakes in Arkansas and When to Watch For Them

According to the UA Division of Agriculture, Arkansas has a total of 39 species of native snakes, and only six of those are venomous: the eastern copperhead, northern cottonmouth, western diamond-backed rattlesnake, timber rattlesnake, western pigmy rattlesnake, and Texas Gulf-coast coral snake. Knowing each species and when they are most active is one of the most practical safety steps you can take.

For a broader perspective on dangerous species, you can also explore the most venomous snakes in North America and see how Arkansas’s six species compare.

Eastern Copperhead
The southern copperhead is one of the most abundant venomous snakes in Arkansas. Copperheads are the most widespread and can be found in almost any habitat statewide, including suburban and urban green spaces. This adaptability is why they are the most frequently encountered venomous snake. You are more likely to see them active during the day in the spring and fall when the weather is cooler. During the middle of summer, Eastern Copperheads are often nocturnal.

Northern Cottonmouth (Water Moccasin)
Cottonmouths occur throughout most of Arkansas except upland Ozark streams in certain northern counties and parts of southwestern Arkansas. They inhabit rivers, streams, swamps, lakes, marshes, ponds, and drainage ditches, and are the only venomous snake in Arkansas regularly found in water. Cottonmouths are the only venomous snake found in water in Arkansas, and they’re more likely to swim in brackish water such as streams or swamps.

Timber Rattlesnake
A variety of habitats support populations of this snake, including south-facing rocky outcrops, upland hardwood forests, brushy fields, and pine plantations as well as forested floodplains and swamps. Timber rattlesnakes are found all over Arkansas, mainly in forests and farms. They are ambush hunters and can strike quickly, although they don’t naturally bite unless threatened.

Western Pygmy Rattlesnake
Western Pygmy Rattlesnakes occur throughout much of Arkansas, including the Ozark Highlands, northern Boston Mountains, Ouachita Mountains, and South Central Plains, most commonly in southern and eastern regions. They inhabit cedar thickets, mixed forests, rocky areas, and marshes, preferring habitats with ample ground cover near water sources. These shy, non-aggressive ambush predators remain most active during warmer months from late spring through early fall.

Western Diamond-backed Rattlesnake
There are spotty records of the western diamondback rattlesnake in the state, with specimens coming from central and western counties. It inhabits dry, rocky habitat characterized by exposed rocky escarpments, rocky glades, and talus slides. Active primarily April through October.

Texas Gulf-Coast Coral Snake
Fortunately, coralsnakes are usually docile and seldom bite when disturbed. Few people encounter coralsnakes because of their highly secretive habits in forests in southwestern Arkansas. The coralsnake has potent venom which is neurotoxic, attacking the nervous system of its prey. Venom is injected through short fangs requiring the coralsnake to bite and chew its prey. You can learn more about telling these apart from harmless lookalikes by reading about the difference between milk snakes and coral snakes.

Important Note: AGFC officials pointed out that many of the so-called “tricks” to identifying venomous snakes such as head or pupil shape are incorrect. The most reliable method is learning the color patterns of each of the six venomous species. You can also explore the most venomous snakes in the U.S. for additional context on how Arkansas species rank in terms of venom potency.

Where Snakes Are Most Commonly Found in Arkansas

Snakes gravitate toward places that offer food, cover, and the right temperature range. “Snakes are going to be where they can find food and shelter,” said Shannon Caldwell, 4-H Center program director for the University of Arkansas System Division of Agriculture. “If there’s going to be rodents in an area, there’s potentially going to be things that want to eat rodents there, snakes included.”

Different habitats attract different species across Arkansas:

• Forests and Rocky Terrain: The Ozark and Ouachita Mountains are prime habitat for Timber Rattlesnakes and Copperheads. The rocky terrain, dense forests, and ample food supply are ideal for them.
• Wetlands and Waterways: The Arkansas River Valley and Delta are where you are more likely to encounter Cottonmouths, especially in and around the many rivers, bayous, and agricultural irrigation ditches.
• Southwestern Arkansas: This region is the primary home for the Texas Coral Snake and the Western Diamond-backed Rattlesnake, which prefer the drier, sandier soils and pine-oak forests typical of this area.
• Near Homes and Yards: Snakes like dark, damp areas with plenty of cover — like wood piles — unmowed lawns with tall grass, and overgrown shrubbery.
• Lakes and Reservoirs: Hot Springs National Park, seated in the Ouachita Mountains, is home to a variety of water bodies, from streams to natural hot springs, and up to 28 different snake species. The park’s diverse ecosystems, ranging from thermal springs to forested trails, boast both venomous and non-venomous snakes.

With an estimated 39 native snake species, Arkansas is a hotbed for reptile activity, from the rolling hills of the Ozarks to the banks of the Mississippi River. The state has a huge selection of lakes, creeks, rivers, swamps, and other wetlands within its borders, due to which numerous different reptiles of all sorts call it home.

Inside buildings, the pattern shifts seasonally. Snakes enter a building because they’re lured in by dark, damp, cool areas or in search of small animals, like rats and mice, for food. During cold months, snakes often try to enter crawl spaces, cellars, sheds, and basements.

To reduce snake presence around your home, make sure you don’t have birdseed lying around, as this is a food source for rodents which attract snakes. Try to eliminate any spaces where snakes could hide from the heat and sun. You may also find it helpful to know about animals that eat snakes — maintaining a healthy yard ecosystem can naturally help keep snake populations in balance.

Key Insight: Non-venomous snakes, such as the king snake, will eat venomous ones. Having harmless snakes around your property can actually reduce the presence of dangerous species.

What to Do If You Encounter a Snake in Arkansas

Encountering a snake — even a venomous one — does not have to be a dangerous situation. Snakes do not purposefully try to do harm. A venomous snake observed from a distance and left alone is completely harmless. Most snakebites occur when snakes are harassed or threatened, such as when attempting to harm or kill them.

Here is a calm, step-by-step approach to handling a snake encounter safely:

1. Stop and back away slowly. Snakes will usually go to tremendous measures to avoid encountering humans. Give it space and it will likely move on.
2. Do not attempt to identify it up close. If you come across a snake and are unsure of what you’re dealing with, it’s best to back away and leave the snake alone. Call a professional if it’s in your yard or house and you want it removed.
3. Never try to kill it. Many snake bites occur when untrained and ill-equipped people attempt to kill a snake. It is also illegal under Arkansas law in most circumstances.
4. Watch your surroundings. Snakes wait for their prey underneath or beside logs, rocks, and debris. When outdoors, probe ahead with a stick before reaching into brush or under objects.
5. Dress appropriately. Wear close-toed shoes or boots, as many snakebites result when walking barefoot or wearing sandals around the yard.
6. If bitten by a venomous snake, go to the hospital immediately. If you get bit by a venomous snake, immediately go to the hospital where you can be monitored and treated.
7. Do not use folk remedies. Cold packs, cutting and sucking venom at the bite site, and even electric shock are all talked about, but they don’t work. Medical treatment with antivenom is the only effective response.

If you need a snake removed from your property, Arkansas has a volunteer organization called Cold Blood Warm Hearts that will relocate nuisance snakes at no charge. The volunteers are trained and equipped to properly catch and handle the snakes to minimize the likelihood of being bitten.

You can also report nuisance wildlife by contacting the Arkansas Game and Fish Commission. To report nuisance wildlife, such as snakes in your home or yard, call the Arkansas Game and Fish Commission’s nuisance wildlife hotline at 833-345-0315.

Common Mistake: Do not use a commercial snake bite kit; they tend to do more harm than good. The best action after any venomous snakebite is to remain calm, immobilize the affected limb, and get to an emergency room as quickly as possible.

The most important thing to remember is that knowledge reduces risk. Learning about the state’s 39 native snake species can help Arkansans better enjoy their time outside. “The best thing to do is learn about these snakes because the more you learn, the better you can understand which are venomous and which are not,” said Shannon Caldwell of the University of Arkansas System Division of Agriculture.
