  • Make use of reflective surfaces to scare sparrows

It is impossible to protect the wren houses from sparrows without special care. Carelessness can only lead to damage. So, it is important to take care of wren houses. You can follow the above-mentioned guidelines in order to provide protection to your wren houses. The right implementation of all the above methods works effectively to keep sparrows away from wren houses thus providing them protection. 

Here is a complete detail of all above methods so that you can implement them in a correct way for desirable results.

Keep an accurate size of entrance hole:

The size of the entrance hole of wren houses matters a lot in order to provide protection to wren houses. As the House Wrens are tiny birds so a small size hole can be enough for their entrance. Large size holes can allow the entry of sparrows. Sparrows may make nests in the wren houses and can damage them.

They can also kill the House Wrens and can destroy their eggs. So, you must be very careful while building or buying a wren house. The diameter range of the entrance hole of wren houses should be 1 ⅛ -1 ½ inches. This size prevents the sparrow’s entrance, thus keeping them out of wren houses. If the size of the entrance hole is larger than 1 ½ then sparrows can easily pass through them and can enter the wren house, resulting in damage.

. You can measure the hole size by using a size measuring tape to keep an accurate size of entrance hole.

Make use of reflective surfaces to scare sparrows:

The use of reflective surfaces is among the easiest ways to keep sparrows away from wren houses by scaring them. You can use anything with a reflective surface such as CDs. CDs are easily available in the market. Take CDs and thread and pass the thread across the hole of the CDs and tie them tightly.

Then tie the thread with a branch of a tree near the wren house. Whenever the sparrows come near the wren’s house, they get scared by hanging CDs due to their reflective surfaces and fly away from them.

Perches should be absent:

The presence of the perches can be a danger to the Wren houses as they attract the sparrows and other birds. The sparrows usually sit on the perches. So it is necessary to select a wren house with no perches. If you hang or place the wren house at a site near the perches, then you can cut or remove them by using sharp cutting material.

The best way is to avoid buying wren houses with perches or to place them on or near perches to keep the sparrows away from them.

Put selective food in wren house:

Putting the selective food in the wren houses can help in keeping the sparrows away from them. Sparrows are mostly attracted to the places having their favorite food. They mostly eat cracked corn, millets, wheat, milo, etc. So you should not put these foods in the wren houses.

The House Wrens love eating sunflower chips, pieces of peanuts, Bark Butter, etc. The sparrows don’t like these food materials. So you should put this type of food in the wren houses to protect them from sparrows. Moreover, you can also put the cracked corns in the bird feeders and can put them on the ground many miles away from the wren houses. The sparrows will eat the food from here and will not come near wren houses.

Place decoys near wren house:

Scaring the sparrows by placing decoys near wren houses can be an effective way to keep them out of wren houses. You can use different types of decoys such as rubber snakes and plastic owls. The owls and snakes are predators of sparrows, so their decoys can effectively scare them.

These decoys are easily available in the market. You can put these decoys on the land near the wren houses or can place them on the branches of the trees. The decoys act as frightening material to sparrows, so they avoid coming near them due to fear of dying. In this way, you can protect wren houses from sparrows.
