When cottonmouth are recorded in Georgia
Yes, cottonmouths live in Georgia, mainly in the coastal plains and swamplands of the southeastern part of the state. They prefer wet habitats near water and are most active during warm months. Bites are uncommon, and with prompt medical care, they are rarely serious. Most people who spend time outdoors in Georgia will never encounter one.
Are they in Georgia?
Cottonmouths are established in Georgia, particularly in the coastal plains and wetland regions of the state. They are most common in southeastern Georgia near the Dismal Swamp, Okefenokee Swamp region, and other low-lying areas with fresh or brackish water. Cottonmouths are venomous water snakes native to the southeastern United States, ranging from North Carolina through Florida and west to Texas. In Georgia, they are found in suitable habitat throughout the southern and eastern portions of the state, though they avoid urban and developed areas. They are semi-aquatic, meaning they split their time between water and land. Cottonmouths are not aggressive, and most encounter people only by accident when moving through their habitat. If you live in northern Georgia or in urban Atlanta, your chance of seeing a cottonmouth is extremely low. For more information, see ourGeorgia wildlife guide.
How dangerous is it?
A cottonmouth bite delivers venom that causes localized swelling, pain, and discoloration. Bites are medically significant and require professional medical attention, but they are rarely fatal in healthy adults with prompt care. The bite itself is painful and can cause tissue damage around the wound site. Swelling typically begins within minutes and may continue for hours. In the rare event of a bite, the severity depends on several factors: the size of the snake, the amount of venom injected, and how quickly you get medical treatment. Most cottonmouth bites in the United States result in full recovery with hospital care. Deaths from cottonmouth bites are uncommon and usually occur only if someone delays seeking medical help or has underlying health conditions. The key to a good outcome is staying calm and reaching a hospital quickly. For more on cottonmouth in Georgia, see ourGeorgia cottonmouth guide.
How to recognize one
Cottonmouths are thick-bodied water snakes, typically 2 to 4 feet long, though they can reach up to 5 feet. They have a distinctive triangular head that is wider than their neck, a characteristic shared with many venomous snakes. Their body color ranges from tan and brown to dark olive or nearly black, often with darker bands or patterns. Young cottonmouths are brighter, sometimes with reddish or yellow patterns. The inside of their mouth is white or pale, which is how they earned their common name. When threatened, they open their mouth wide and hold still to display the white interior, a distinctive defensive display. Cottonmouths are found in and around water: swamps, marshes, rice paddies, ditches, ponds, and slow-moving streams. They hide under logs, leaf litter, and debris near water's edge. They are semi-aquatic and may be spotted swimming or basking on vegetation at the water's edge. You can also browseGeorgia wildlife.
What to do if you are bitten or stung
If a cottonmouth bites you, stay calm and seek medical care immediately. Your first steps are simple: move away from the snake to prevent additional bites, remove any tight rings or bracelets from your hand or arm in case swelling occurs, and keep the bitten area still and below heart level if possible. Do not apply ice, do not cut or suck the wound, and do not apply a tourniquet. Do not try to kill or capture the snake. Wash the bite gently with soap and water if you can do so quickly, but do not delay getting to a hospital. Call 911 or have someone drive you to the nearest emergency room. If you are alone and far from help, call 911 and stay still while awaiting rescue. 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. Hospital staff will monitor swelling and pain and may administer antivenom if needed. The sooner you receive care, the better your outcome.
How to prevent encounters
Preventing a cottonmouth encounter is mostly about staying alert in their habitat. Wear closed-toe shoes and long pants when hiking or wading in wet areas of Georgia. Stay on marked trails and avoid tall grass and brush near water. Do not reach into places you cannot see clearly, such as dense vegetation or under logs. Check your shoes, hats, and gear before putting them on if you have been outdoors near water. Keep your yard clear of debris piles, leaf litter, and brush that could shelter snakes. Remove sources of standing water if possible, or at least inspect the edges before walking near them. If you see a cottonmouth, simply leave it alone and move in the opposite direction. Cottonmouths prefer to flee when given the chance. Do not attempt to handle or kill a snake you see. Teach children to never touch a snake they do not recognize. Swimming in clear pools or lakes is safe; cottonmouths are far more common in swamps and slow-moving water with vegetation.
Where in Georgia and when
In Georgia, cottonmouths are restricted to the coastal plains and wetland regions, particularly in the southern and southeastern portions of the state. They are abundant in the Okefenokee Swamp area of southeastern Georgia, along the Savannah River, and in other swampy and marshy regions near the coast. They occur in lowland areas around rivers and streams that flow through southeastern Georgia. Cottonmouths are active year-round in Georgia, though they are less active in the coldest winter months when they may den up in protected places. They are most visible and active from late spring through early fall when temperatures are warm. They are primarily active during the day but may hunt at night during the hot summer months. In winter, they become dormant or lethargic and are rarely encountered. Coastal and low-country areas of Georgia have higher densities of cottonmouths than inland regions. Northern Georgia and the Appalachian regions have no established cottonmouth populations. For more information aboutwildlife in Georgia, check our broader guide.
Harmless lookalikes
The most common water snakes that people mistake for cottonmouths are the harmless water snakes: banded water snakes, green water snakes, and brown water snakes. These snakes are non-venomous and found in the same wetland habitats as cottonmouths. Water snakes are slimmer and more graceful than cottonmouths, which are stocky and heavy-bodied. The water snakes also lack the distinctive triangular head and pale mouth of the cottonmouth. Many people confuse young cottonmouths, which have bright bands or patterns, with banded water snakes. If you see a snake in Georgia water and you are not certain it is a cottonmouth, it is far more likely to be a harmless water snake. The safest approach is to simply leave any snake alone and keep your distance. Even if you see a cottonmouth, it will not chase you and will usually try to escape. Most people never see a cottonmouth at all, even in areas where they are present. Ourcottonmouth in Georgiaguide has photos to help with identification.

Swelling, bruising, and discoloration appear quickly around the bite. The pain is immediate and can be severe. Are cottonmouths deadly? Cottonmouth bites are medically serious and require hospital treatment, but deaths are extremely rare in healthy adults who receive prompt medical care. With antivenom and supportive treatment, most people recover fully. What time of year are cottonmouths active? Cottonmouths are most active from late spring through early fall in Georgia. They are sluggish during winter months and are rarely seen then. Is swimming in a Georgia lake or pool safe? Swimming in clear, treated pools is completely safe.
