Are they in Arizona?
Yes, the Sonoran coral snake, also called the Arizona coral snake, is established in southern Arizona, primarily in Pima and Graham counties and parts of Cochise County. They are found in desert and semi-arid regions with suitable moisture and cover, including desert scrub, canyon habitats, and arroyos with more vegetation. Their range in Arizona is concentrated in the southern part of the state, with scattered populations in areas with access to oak woodlands and desert wash habitats. They prefer areas with adequate moisture, which limits them to regions where rainfall is more consistent or where arroyos provide water flow. Coral snakes are most commonly found in the foothills and valleys of southern Arizona rather than in the driest desert plains. Even within their established range in Arizona, they remain relatively uncommon and are encountered only rarely by people. OurCoral Snake in Arizonaguide provides more specific information about their distribution in the state.
How dangerous is it?
The Sonoran coral snake is venomous and its venom is potent, but bites are extraordinarily rare in Arizona. Most people who spend time outdoors in southern Arizona will never encounter a coral snake. These snakes are extremely shy and will try to flee rather than bite when encountered. They have small mouths and short fangs located toward the back of their head, making it difficult for them to bite humans effectively. Bites require the snake to chew to deliver venom, which rarely happens when a human is the potential victim. When coral snake bites do occur in Arizona, they are almost always the result of someone deliberately handling or attempting to capture the snake. A coral snake bite is medically serious and requires immediate medical attention, but with proper treatment, outcomes are very good. No deaths from Sonoran coral snake bites have been reported in Arizona in recent decades, even before modern antivenin was available. The risk from a coral snake is extremely low if you simply leave any snake alone.
How to recognize one
Sonoran coral snakes are typically 16 to 20 inches long, though they can occasionally reach up to 24 inches. They are slender snakes with distinctive bands of red, yellow, and black that encircle their entire body. The key identifying feature is that their red bands touch their yellow bands. They have a small head, and the coloring pattern extends from the tip of their snout to the end of their tail. Coral snakes are secretive and spend most of their time under rocks, leaf litter, logs, and in burrows where they hunt for small lizards and other snakes. They are active primarily at night and during wet weather when moisture and food are more active. You might find one under a rock or piece of wood after rain, or in areas with dense ground cover near water sources. If you find a small banded snake with red and yellow bands adjacent to each other, assume it is a coral snake and observe from a distance or contactArizona wildlife.
What to do if you are bitten or stung
Stay calm and remain as still as possible if you are bitten by a coral snake. Immobilize the bitten area and remove any tight jewelry or clothing that might restrict swelling. Do not try to capture or kill the snake, as this increases the risk of another bite. Seek medical attention immediately, ideally by calling 911. 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. Do not apply ice, do not attempt to suck out venom, and do not use a tourniquet. Do not give any medication unless directed by medical professionals. The key is to get professional medical attention as quickly as possible. Coral snake antivenin exists and is highly effective when administered promptly, so survival rates and recovery outcomes are very good with proper medical treatment.
How to prevent encounters
The best way to avoid a coral snake encounter in Arizona is to be aware of your surroundings when hiking or spending time outdoors in southern Arizona, especially in foothills and canyon areas. Wear closed-toe shoes and long pants when hiking, particularly in areas with dense brush or ground cover. Shake out your shoes, clothing, and bedding before putting them on, and check inside gloves and hats. Be cautious when moving rocks, lumber, or debris, as coral snakes often hide beneath these materials. Keep your yard clear of large piles of leaves, wood, and rocks where snakes might shelter. Seal cracks around the foundation of your home and under doors and windows. Remove potential food sources like rodents and insects by keeping garbage secured and pet food indoors. Never handle a snake unless you are absolutely certain of its identification. Most of ourwildlife guidesinclude specific tips for your region.
Where in Arizona and when
In Arizona, coral snakes are concentrated in the southern part of the state, primarily in Pima, Graham, and parts of Cochise counties. They prefer areas with desert scrub, canyon habitats, desert washes, and foothills that receive more moisture than the driest desert plains. They are found in elevation ranges from about 2,000 to 4,500 feet, where vegetation is more abundant and water is more accessible through rainfall and underground seepage. Coral snakes are most active during the warmer months, particularly from late spring through early fall, with peak activity during summer monsoon season when moisture increases and prey activity increases. During the cooler winter months, they are less active and remain hidden. On warm nights or during humid, rainy weather, they are more likely to be active and visible. Even during their active season, most people will not see one because they spend most of their time underground or under cover.

Harmless lookalikes
The good news is that several common, harmless snakes in Arizona have similar coloration to coral snakes. The Arizona mountain kingsnake is the most commonly confused lookalike, with red, white, and black bands, though the arrangement is different from coral snakes. The scarlet snake also has red bands but lacks the distinctive coral snake pattern. Kingsnakes and rat snakes are common throughout Arizona and are completely harmless. Arizona whip snakes, gopher snakes, and many other native species are harmless and important parts of the state's ecosystem. Most banded snakes you encounter in Arizona will be kingsnakes or other harmless species rather than coral snakes. The shy behavior of actual coral snakes makes encounters even rarer, and harmless lookalikes are far more commonly seen by hikers and outdoor fans. If you find a snake and are unsure of its identity, the safest approach is to leave it alone and observe from a distance. For more details, read ourmore on Coral Snake in Arizona.
