What To Do If You See a Snake in New Jersey

If you encounter a venomous snake, the timber rattlesnake or northern copperhead, ensure you keep a safe distance of a minimum of five feet. Young children and pets should be put further back.

They often give what is known as a dry bite, which is a defense action rather than biting for food.

If bitten by one of the venomous snakes in New Jersey, it is important to remain calm and call 911 straight away.

If you encounter any snake in your home, call a snake removal company right away. If you leave the snake, it should not harm you.

Close the windows and doors in the room where the snake is, reducing the risk of it moving around the home, keeping your five-foot distance.

Put a towel under the door to reduce the risk of the snake escaping until the snake removal company arrives.

In the event, you know the snake is not venomous and it’s close to an exterior door, you can try and brush it out. Though keep your distance, as it may turn around and try and bite or flee in the wrong direction.

How to Prevent Snakes

The good news is that there are a number of things you can do to prevent snakes in your home and yard, these include:

  • Mow your lawn and keep the grass short, this will help deter snakes and help you identify snake activity.
  • Remove any debris piles and mulch. Mulch generates heat as it decomposes, which is a warm spot for snakes, while debris can attract rodents, offering easy food for snakes.
  • Feed your pets inside or remove food bowls as soon as your pet finishes eating, reducing the risk of attracting rodents and in turn, attracting snakes.
  • Seal any cracks and crevices in the home and ensure your outbuilding foundations are sealed It is common for garter snakes and milk snakes to move into homes during summer months.
  • Remove bird houses. While bird houses are beautiful, the chirping can attract snakes to your yard. If you love your bird house, place it on a metal pole or a wooden post, wrapping it in metal sheeting to deter any snakes.
  • Reduce the urge to feed wild birds in your yard. Birds are naturally messy, knocking food to the ground and attracting rodents.
  • Use your firewood during winter, as they become a great hiding place for snakes during the summer. If you keep firewood throughout the year, place it on a rack at least one foot above the ground.
  • If you have fruit trees, ensure you pick up any fallen fruit


Snakes are common throughout New Jersey with only two being venomous and dangerous to humans: the Northern copperhead and timber rattlesnake.

Being able to identify snakes in the State helps you identify if you need to be concerned or not. Try the preventative measures to reduce the risk of snakes turning your home or yard into their new habitat.
