If you own a birdhouse, you may want to learn how to make a birdhouse squirrel proof using predator guards. A birdhouse predator guard you say? Yes, these are small metal guards that are utilized to prevent a squirrel from gnawing out the existing hole to the birdhouse. They work perfectly if youโ€™re looking to create a squirrel proof bird house.

You can buy specific guards such as a bluebird house predator guard or you can purchase predator guards that are built specifically for chickadees which tend to have a smaller hole in the guard.

A squirrel will tend to gnaw at the openings of birdhouses in the fall in preparation for the cold winter days. Sometimes a squirrel might just be looking for seeds that a bird may have stored in the birdhouse or maybe the squirrel is looking for shelter in which to store nesting material. From my experience the only time I have seen a squirrel gnaw at the opening of a birdhouse is this past fall.

Two out of the three birdhouses that I own had nothing in them when I attempted to clean them out this spring. One of them was full of grass that resembled what you would find deposited by a bird. But I know that the grasses in this birdhouse were placed in there by a grey squirrel because no birds had nested in there over the spring and summer.

Steps to Make a Birdhouse Squirrel Proof

  1. Identify the Predator Guard that will be the right size for the bird that will be using the birdhouse.
  2. Acquire high quality predator guards – one for each birdhouse that you own.
  3. Remove each birdhouse one by one from the tree or pole upon which it is attached.
  4. Center the predator guard over the existing birdhouse opening whether or not it has already been gnawed by a squirrel.
  5. Utilizing an awl, insert the awl into each of the 4 holes of the metal predator guard marking the location of where the screws will be inserted. This will help to prevent against splitting the wood when inserting the screws and will also allow you to easily insert the screws.
  6. Utilizing either a manual screwdriver or a cordless drill, insert each screw in their perspective hole and snug them down.
  7. Return each squirrel proof bird house to their original locations.
  8. You have now successfully installed a birdhouse predator guard making your birdhouse squirrel proof.
