Copperheads are some of the most common snakes across the eastern United States. These venomous snakes are quite beautiful but can also pack quite the punch if you happen to get bit. There are five subspecies of copperheads (more on this below), with the northern copperhead being the most widespread. If you live from Nebraska to the eastern coast, you have likely encountered one of these snakes before! Today, we are going to explore copperhead snake bites and learn just how deadly they are. By the end, you should know a bit more about the venom of these snakes, plus have some guidance on what to do if you should encounter them. Let’s get started!
How dangerous are copperhead snake bites?
Copperheads are some of the more common venomous snakes that can be found in the US. With their venomous nature and wide range, bites are bound to happen. If you get bit, however, just how dangerous are they?
The venom of a copperhead is known as “hemotoxic”. Hemotoxic venom is characterized by tissue damage, swelling, necrosis, and damage to the circulatory system. While this may seem terrifying, it is all relatively localized. Although it may be painful, copperhead bites are only mildly dangerous to most people. The venom of a copperhead is actually the lower among all pit vipers, and of the 2,920 people bitten annually by copperheads, just .01% result in fatalities. For reference, the eastern diamondback rattlesnake injects up to 1,000 mg per bite and has a 20-40% mortality rate left untreated.
Aggression and defensivness
While most humans consider all snakes to be “out to get them”, this is actually far from the truth. Most snakes want to avoid humans, especially the copperhead. In fact, most copperheads will give a warning bite to an encroaching human. These warning bites don’t inject venom and are known as a “dry bite,” requiring no antivenom administration.
With the reluctance that copperheads have to bite, the likelihood of receiving a dry bite if they do strike, and the relatively low toxicity of their venom, these snakes are among the least dangerous venomous snakes in the US.
What do you do if bitten by a copperhead?
If you happen to see a copperhead, your best option is to leave it alone. They usually try to remain unseen and don’t want interactions with a big, scary human. Still, accidents happen, and most human bites occur where the human doesn’t see the snake and is moving or reaching into the snake’s space.
If you are bitten by a copperhead, the first thing you should do is seek medical attention. Although it is possible that the bite was dry, it is still wise to seek help in the case that a reaction develops. If the wound doesn’t swell or hurt any more than a standard puncture wound, it’s likely that it was dry.
In rare cases, some people may be allergic to copperhead venom. Similar to a bee allergy, these reactions can be fatal and fast treatment is essential.
After emergency services are called, follow these steps:
- note the time of the bite
- remove watches and rings (in case of swelling)
- wash the area with soap and water
- keep the wound lower than the heart
- don’t try to “suck out the venom” and don’t apply a tourniquet
In most cases, people bitten by a copperhead are back to normal within 2-4 weeks.

FAQs (Frequently Asked Questions)
What states are copperhead bites most common?
The state with the most reported copperhead bites per capita is North Carolina. After North Carolina, they’re most common in West Virginia, Arkansas, Oklahoma, Virginia, and Texas. The rate of copperhead bites is more than three times as high in North Carolina compared to Virginia or Texas.
How many species of copperheads are there?
There’s an ongoing debate in the scientific community around Copperhead species. Previously, there were five recognized subspecies. However, recent gene analysis shows that there are two distinct copperhead species: the eastern copperhead and the broad-banded copperhead. Broad-banded copperheads live in Texas, Oklahoma, Kansas, and Mexico while eastern copperheads across the eastern seaboard.
