The presence of a coral snake, one of North America’s most venomous species, requires understanding its behavior for safety. This brightly colored reptile possesses a potent neurotoxic venom that affects the nervous system. The primary danger arises not from the snake’s aggression, as they are generally secretive, but from human attempts to kill or handle them. Most bites occur when people interfere with the snake, making confrontation unnecessary and dangerous. Prioritizing safety means managing the situation non-lethally, often by allowing the snake to pass or calling trained professionals for removal.
Crucial Identification: Separating Coral Snakes from Non-Venomous Lookalikes
Accurate identification is paramount because several non-venomous species closely mimic the coral snake’s distinctive pattern. The Eastern Coral Snake (Micrurus fulvius) is characterized by a sequence of black, yellow, and red bands that completely encircle the body. The critical distinction lies in the order of the bands: on the venomous coral snake, the red bands always touch the yellow bands.
This pattern is summarized by the mnemonic rhyme, “Red touches yellow, kill a fellow; Red touches black, friend of Jack,” which applies to U.S. coral snakes. Harmless mimics, such as the Scarlet Kingsnake, typically have red bands touching black bands instead. The Eastern Coral Snake also has a black snout immediately followed by a yellow band.
In contrast, the non-venomous Scarlet Kingsnake often has a red snout and a pattern where red and yellow are separated by black bands. While the rhyme is a useful tool, color variations or aberrant patterns can occur, making it unreliable in all cases. Therefore, the safest practice is to treat any snake with red, yellow, and black banding as potentially venomous, maintaining distance until a professional confirms its identity.
Immediate Safety Measures When Encountering a Snake
If you spot a snake with this distinct banding pattern, the immediate action is to back away slowly. Maintain a minimum distance of six feet, as this is outside the striking range of most species. Remain calm and avoid any sudden movements that the snake might perceive as a threat.
Coral snakes are naturally reclusive and non-aggressive, biting only when cornered, stepped on, or intentionally handled. They spend most of their time underground or under debris, making encounters rare. Never attempt to capture, kill, or move the snake, as this is the most common scenario leading to a bite.
Keep all pets and children away from the area, as their curiosity can provoke a defensive bite. Observing the snake from a distance will usually result in it moving away on its own, seeking to avoid contact. Once the snake has disappeared, you can proceed with non-lethal management options to prevent its return.
Non-Lethal Removal and Exclusion Methods
When a coral snake is repeatedly found on a property, the safest and most responsible solution is to engage professional help for removal. Local animal control, wildlife specialists, or licensed experts are trained to safely capture and relocate the snake without harming it. These professionals possess the necessary equipment and experience, making this preferable to a dangerous DIY attempt.
A long-term strategy involves making the property less attractive by eliminating potential shelter and food sources. Snakes are drawn to areas providing cool, dark hiding spots and ample prey. Exclusion methods focus on removing these attractants:
- Removing piles of debris, such as wood stacks, leaf litter, and rock piles.
- Storing firewood at least 12 to 18 inches off the ground and away from structures.
- Controlling rodent populations by securing trash cans and pet food storage.
- Keeping grass closely mowed and trimming low-lying shrubs to reduce cover.
- Sealing any foundation cracks or openings larger than a quarter-inch with mortar or hardware cloth to prevent entry into buildings.
Emergency Medical Protocol for a Coral Snake Bite
If a coral snake bite occurs, immediately call 911 or emergency services. Coral snake venom is a neurotoxin that can cause paralysis and respiratory failure. While initial symptoms at the bite site may be minimal, severe systemic effects can be delayed for several hours. Definitive treatment requires antivenom, which is only administered in a hospital setting.
While awaiting emergency personnel, the patient must remain calm and still to slow the spread of venom. The affected limb should be immobilized and kept below heart level. Remove all restrictive items, such as rings, watches, or tight clothing, from the bitten extremity before swelling begins.
Avoid traditional, but harmful, first aid practices. Do not apply ice, cut the wound, attempt to suck out the venom, or use a tourniquet, as these actions are ineffective and can cause tissue damage. Prompt transport to a medical facility for continuous monitoring and antivenom administration is the only appropriate course of action.
