How to recognize one

If you travel to states where rattlesnakes live, it is helpful to know what they look like. Timber rattlesnakes, the closest rattlesnake species to New Jersey, are large, heavy bodied snakes with triangular shaped heads. They are usually light tan or gray with dark chevron or V shaped bands running the length of their bodies. A distinctive rattle at the tail tip produces a buzzing sound when vibrated. Rattlesnakes have heat sensing pits along their lower jaw that help them locate prey. However, in New Jersey, you will not encounter these snakes in the wild. The snakes you find in New Jersey are harmless species with different characteristics. You can also browseNew Jersey wildlife.

What to do if you are bitten or stung

Seek medical attention promptly. Do not attempt to capture or kill the snake. Do not apply ice, tourniquets, or try to cut the wound. 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.

How to prevent encounters

While you do not need to worry about rattlesnakes in New Jersey, general snake safety practices are still good habits. Wear closed toe shoes when hiking or spending time in wooded areas. Watch where you place your hands and feet, especially near woodpiles or rocky areas. Keep brush and debris cleared from around your home. Seal gaps under doors and around building foundations. Remove rodent populations from your property, as they attract snakes. Do not intentionally handle any snake you encounter. If you see a snake while hiking or at home, simply move away and give it space. Most New Jersey snakes are beneficial and help control pest populations.

Where in New Jersey and when

The nearest wild populations of timber rattlesnakes live in Pennsylvania, particularly in the western and southern regions, and in parts of New York. These distant populations are the only eastern rattlesnakes in the United States. New Jersey's location along the Atlantic coast, combined with its urban development, habitat fragmentation, and climate, makes it unsuitable for rattlesnakes. The state has never had an established rattlesnake population in recorded history.
