Snakes: Why They Belong in Our Yards, Woods, and Wetlands

Snakes are among the most misunderstood animals in North America. They are often treated as dangerous by default even though most native species are nonvenomous. In most states only a handful of native snake species are venomous; the great majority are nonvenomous, and many are protected by state law.

Snakes are ecological middle managers

Snakes consume rodents, insects, amphibians, fish and other snakes depending on species. In turn, they feed hawks, owls, mammals and larger reptiles. Remove snakes from a food web and you remove both predator and prey.

Defensive is not aggressive

A snake that coils, strikes, musk-sprays or vibrates its tail is responding to a perceived predator. Humans tower over snakes. Giving the animal space turns most encounters into non-events.

Killing increases risk

Many bites occur when people try to capture or kill a snake. The safer strategy is distance. If the snake is not in immediate danger and not trapped inside a human living space, letting it leave is usually the simplest solution.

What to do

The path from fear to coexistence begins with one simple fact: most snakes want nothing from us. They need space, habitat and the chance to do their ecological job without being killed for being seen.
