Are they in Oklahoma?
Yes, rattlesnakes are well established throughout much of Oklahoma. The state has at least five rattlesnake species. Western diamondback rattlesnakes are the most common and widespread, found in the western, southwestern, and central parts of the state. Timber rattlesnakes inhabit the forested eastern portions, including areas around the Wichita Mountains and surrounding regions. Oklahoma also has prairie rattlesnakes, western massasaugas, and other species in various habitats. Western diamondbacks prefer drier regions, while timber rattlesnakes favor forested areas. Most encounters occur in spring through fall when temperatures are warm. The western part of the state has higher concentrations of western diamondbacks.

How dangerous is it?
A rattlesnake bite in Oklahoma is medically serious and requires immediate care, but deaths are extremely rare with prompt medical treatment. Western diamondbacks have hemotoxic venom that destroys tissue and causes severe swelling. Timber rattlesnake bites also produce hemotoxic venom with similar effects. About 85 percent of bites occur on the lower legs and feet when people step on or near a snake. Symptoms develop rapidly and include pain, swelling, discoloration, and potentially serious complications without treatment. Antivenom is highly effective when given soon after a bite. Healthy adults who receive prompt emergency room care rarely face life threatening complications. Oklahoma averages around 50 to 70 snake bites per year, but only a small fraction are from rattlesnakes, and deaths are extremely rare.

How to recognize one
Western diamondback rattlesnakes in Oklahoma are large, heavy bodied, and gray or tan with dark diamond shaped blotches. They have a distinctive rattle at the tail tip. Timber rattlesnakes are also large, gray or tan with dark chevron or V shaped bands. Both have triangular heads and heat sensing pits along their jaw line. Prairie rattlesnakes are tan or gray with dark bands. Western massasaugas are small gray or tan snakes with darker bands. All have a distinctive rattle at the tail tip that produces a buzzing sound. Western diamondbacks hide in rocky areas, desert scrub, and grasslands. Timber rattlesnakes hide in forested areas, under logs, and in rocky locations. You can also browseOklahoma wildlife.
What to do if you are bitten or stung
Stay calm and remain still. Remove any rings, bracelets, or tight clothing from the bitten hand or arm immediately, as swelling develops quickly. Keep the bitten area below heart level and avoid movement. Do not attempt to kill or capture the snake. Do not apply ice, tourniquets, or try to cut the wound or suck venom. Seek medical attention immediately by calling 911 or driving to the nearest emergency room. In remote areas, know the location of the nearest hospital. This is general information, not medical advice; if you are bitten, call Poison Control at 1-800-222-1222, or 911 if symptoms are severe. Antivenom and supportive medical care are most effective when given quickly. Time is critical for good outcomes. See all of ourwildlife guides.
How to prevent encounters
Wear closed toe boots and long pants when hiking or working in areas where rattlesnakes occur. Watch where you place your hands and feet, especially in rocky areas and grasslands. Shake out sleeping bags, clothing, and boots before use. Keep wood piles and debris away from your home. Clear brush and tall grass from around buildings and yards. Do not reach under logs or into rocky crevices. Listen for the rattle, which is your warning to back away. Make noise while hiking so snakes can move away before you reach them. Do not hike alone in remote areas. If you encounter a rattlesnake, back away slowly and give it plenty of space to retreat.
Where in Oklahoma and when
Rattlesnakes are found throughout much of Oklahoma in diverse habitats. Western diamondbacks are most common in the western, southwestern, and central portions of the state, including the Oklahoma Panhandle, Beaver County, and regions south through the Caddo National Grassland. Timber rattlesnakes live in the eastern forested portions, including the Wichita Mountains area and surrounding Kiamichi Mountains. Prairie rattlesnakes occur in grasslands of the panhandle and western regions. Seasonally, rattlesnakes are most active from April through October when temperatures are warm. In winter, they retreat to dens and become dormant. Spring and early summer see the most activity. ForOklahoma wildlifeinformation, explore our comprehensive guides.
Harmless lookalikes
Bullsnakes, gopher snakes, and water snakes are sometimes mistaken for rattlesnakes in Oklahoma. These large, powerful snakes lack a rattle and are completely harmless. When threatened, some flatten their bodies, hiss, and strike, mimicking a rattlesnake's behavior and startling people. Racer snakes, kingsnakes, and coachwhips are other harmless species in Oklahoma. Coachwhips are long, thin, fast moving snakes that some people fear but are completely beneficial. Most Oklahoma snakes are beneficial predators of rodents and insects. The good news is that your first encounter with a snake is far more likely to be a harmless species. Learning the differences helps reduce unnecessary alarm.
