The notion of snakes chasing humans is a common fear, often perpetuated by anecdotal stories. However, understanding snake behavior can clarify these fears and offer a more accurate perspective. True chasing is not typical behavior for these reptiles.
Why Snakes Don’t Chase
Snakes are generally defensive animals, not aggressive predators toward humans. Their primary goal is self-preservation and avoiding conflict. A snake has nothing to gain by pursuing a person, as humans are too large to be prey and chasing them is not an energy-efficient strategy. Instead, their instinct is to flee, hide, or remain still when threatened.
Many species will attempt to escape as quickly as possible when a human enters their area. If escape is not an option, a snake may resort to defensive displays. This behavior is a response to feeling cornered or provoked, rather than an act of aggression.
Misinterpreting Snake Behavior
Several snake behaviors are often misinterpreted as “chasing” or aggression. A snake might strike or lunge as a warning or deterrent when it feels cornered, which can appear as an advance but is a defensive display. This is a defensive effort to make a perceived threat retreat. Some snakes, like hognose snakes, may even flatten their heads or bodies to appear larger, mimicking more dangerous species as part of their defensive posture.
A snake might also move past a person to reach cover, water, or an escape route, which can be perceived as moving at them. For example, a snake startled on a path might dart in the direction of a person if that is the quickest way to its hiding spot. This movement is coincidental to the person’s location, as the snake is focused solely on finding safety.
While most snakes are not territorial, rare exceptions exist. For instance, a female King Cobra may fiercely guard her nest and eggs, potentially holding her ground or moving towards a perceived threat if disturbed. However, this is highly contextual behavior related to protecting offspring, not a general “chase.” Some snakes might investigate new objects out of curiosity, using their tongue to gather information. This exploratory behavior is distinct from aggression or pursuit.
What to Do During a Snake Encounter
If you encounter a snake, remaining calm and still is important. Sudden movements can startle the snake and provoke a defensive reaction. Give the snake space, maintaining a distance of at least 10 feet, and slowly retreat. Backing away calmly allows the snake to perceive you as non-threatening and encourages it to move away.
Do not harass, attempt to handle, or try to kill the snake. Interfering with a snake significantly increases the risk of a bite, as snakes only bite defensively. Most bites occur when people try to interact with or remove a snake. Instead, observe the snake from a distance and allow it to move on its own.
In certain situations, professional help may be necessary. If a snake is inside your home, in a high-traffic area, or if you cannot identify it and suspect it might be venomous, contact local animal control or a professional snake removal service. These services are equipped to safely identify, capture, and relocate snakes without harming them or people.
