Is A Rattlesnake Living In Your Neighborhood?

We’re here to help. Here are some practical tips:

Deter Rattlesnakes From Your Yard

  • Keep the grass on your property cut short.
  • Remove piles of wood, leaves, or any hiding spots for snakes.
  • Pick up any fallen fruit, keep trash cans securely closed, remove birdfeeders, and feed pets indoors.
  • Check under your house and around the perimeter to close any gaps where a rattlesnake could hide.
  • Exchange mulch and large rock for smaller gravel or river rock that is less attractive to snakes.
  • Add a rattlesnake-proof fence around your yard:  A snake-proof fence is a minimum of 3′ tall, the bottom portion buried at least 3″. There should be no gaps on any sides and be flush with the ground. Concrete slabs placed under the gate are even better. Use mesh 1/4″ in diameter or smaller, or solid, smooth material that snakes cannot climb.
  • Cut away any vegetation that may grow against the fence.

If You Encounter A Rattlesnake

  • If out on a walk, stay a minimum of 10′ away from the snake. Walk around the area or change routes.
  • Always keep your dog or pet on a 6′ or shorter leash, do not allow them to wander.
  • If at home, use a hose and spray the snake from a safe distance.

Did you know most bites occur when the snake is intentionally provoked, or while being captured? Rattlesnakes will only strike in self-defense.
