Are they in New Hampshire?
Coral snakes do not live in New Hampshire. These snakes require warm, humid climates year-round, and New Hampshire's cold winters, short summers, and deciduous forests are entirely unsuitable. Coral snakes live in the warm southeastern and southwestern United States, with the eastern coral snake found from Florida to North Carolina and the Arizona coral snake in the southwestern deserts. OurCoral Snake in New Hampshirepage explains why this threat is not relevant here. The nearest coral snakes live in North Carolina and Florida, thousands of miles away. New Hampshire's actual snake fauna includes water snakes, garter snakes, and a few venomous species like the timber rattlesnake, but no coral snakes. You will never encounter a coral snake in New Hampshire's wild spaces.
How dangerous is it?
Coral snakes are highly venomous and their bites are medically serious, requiring prompt treatment with antivenom. However, coral snakes do not live in New Hampshire, so this is not a practical hazard in your state. In regions where coral snakes do occur, bites are uncommon because these snakes are shy, reclusive, and avoid people. Most bites occur when someone tries to capture or handle the snake. With proper medical care, coral snake bites are survivable, though untreated bites can be fatal. The reassuring truth for New Hampshire residents is that you will never face this hazard while living in or visiting your home state. Your actual snake concerns in New Hampshire are far different and less severe.
How to recognize one
Coral snakes are small snakes, typically 18 to 24 inches long, with distinctive red, yellow, and black bands encircling the entire body. The famous rhyme states 'red on yellow, kill a fellow; red on black, friend of Jack,' referring to the touching pattern of colors on true coral snakes. The head is small and rounded, the snout is black, and the tail is banded like the body. Unlike most venomous snakes, coral snakes have fixed fangs and lack heat-sensing pits. In New Hampshire, if you see any banded snake, you can learn aboutNew Hampshire wildlifewith confidence that coral snakes are not part of our ecosystem. Any snake you encounter in New Hampshire is harmless or a native venomous snake that is not a coral snake.
What to do if you are bitten or stung
Because coral snakes do not live in New Hampshire, being bitten is impossible. However, if you travel to a state where they occur and are bitten, follow these steps: stay calm, keep the bitten area still, and remove any tight jewelry or clothing near the bite. Do not apply ice, do not cut the bite, do not use a tourniquet, and do not attempt home treatment. Get medical attention immediately and tell healthcare providers you may have been bitten by a coral snake. 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 administered by medical professionals is the appropriate treatment.
How to prevent encounters
Prevention is not necessary for coral snakes in New Hampshire because they do not exist here. Focus your attention on the actual reptile hazards you may encounter in New Hampshire, including timber rattlesnakes in western regions. When hiking in New Hampshire, wear closed-toe shoes and stay on marked trails. Do not reach into rock crevices, dense brush, or woodpiles. If you see any snake, observe it from a distance and let it move away. Shake out sleeping bags, tents, and gear before use while camping. Most New Hampshire snakes, including venomous ones, prefer to avoid humans. Reviewour wildlife guidesif you travel to warmer states where coral snakes do occur.
Where in New Hampshire and when
Coral snakes do not occur anywhere in New Hampshire at any time of year. The state is too far north and too cold. New Hampshire's climate has freezing winters and mild summers, with significant snow cover in winter. Coral snakes, being tropical and subtropical reptiles, cannot survive these conditions. They are active in warm months only in states like Florida, Louisiana, and Arizona, typically from April through October. Even in their native range, they are nocturnal and reclusive. For detailed information aboutwildlife in New Hampshire, focus on the species that actually live here through all seasons, including the cold-hardy snakes adapted to northern forests.
Harmless lookalikes
In New Hampshire, you will not see any snake that closely resembles a coral snake. Our native snakes have very different patterns and colors. The milk snake, which occurs in New Hampshire, has red blotches on a gray or tan body, not continuous red, yellow, and black bands. Garter snakes are striped lengthwise, not banded in rings. Water snakes have crossband patterns but lack the bright yellow of coral snakes. The racer and blacksnake are solid-colored. If you somehow worry that a snake is a coral snake, rest assured that New Hampshire's location and climate mean this identification is impossible. All of New Hampshire's snakes prefer to retreat from humans rather than confront them.
