If you are sold on the benefits of having garter snakes in your yard, you might be wondering if there are things you can do to encourage them to visit your yard. Luckily, there are a few things you can do to hopefully increase their presence in your yard:

  • Provide Shelter and Hiding Places: Garter snakes seek shelter under rocks, logs, debris, and vegetation. Create suitable hiding spots by placing flat rocks or boards in various areas of your yard. These structures offer safe havens where garter snakes can rest, hide, and regulate their body temperature.
  • Water Sources: Like all animals, garter snakes need water. If your yard doesn’t have a natural water source, consider adding a shallow, wildlife-friendly water feature such as a birdbath or small pond. Ensure the water source is accessible and safe for the snakes.
  • Minimize Disturbances: Garter snakes are relatively shy creatures. Minimize loud noises, sudden movements, and disturbances in your yard to create a calm environment that encourages them to stick around.

If you aren’t a fan of garter snakes and don’t want them in your yard, then you can pretty much do the reverse of all of the tips listed above: 

  • Remove potential shelter spots: Garter snakes need plenty of places to hide and take shelter to cool themselves down in the heat or keep them warm in the cold. Remove these potential shelter spots by removing debris, rocks, and dense vegetation in your yard.
  • Avoid standing water: Garter snakes need a water source, so if you have ponds or other standing water in your yard, consider covering them. Not to mention, water sources can also attract certain garter snake prey items like frogs, which in turn attracts garter snakes.
  • Create an uncomfortable environment: The presence of lots of people, pets, or livestock can deter garter snakes from wanting to make their way into your yard. 


To wrap things up, having garter snakes in your yard is actually a good thing and if you are noticing them in your yard then you’re in luck! They are great for pest management and supporting a healthy ecosystem.

Not to mention, they are amazing animals in their own right, and seeing one really is a treat. There’s no need to be worried about them in your yard either, as they are completely harmless to people, pets, and property.
