Birds 6

Crows are intelligent and adaptable creatures, but their presence can become a nuisance, especially when they start frequenting your windows. Their loud calls, potential property damage, and droppings can be bothersome for homeowners. If you’re dealing with this issue, this comprehensive guide will provide you with effective methods on how to deter crows from windows.


To deter crows from windows, you can use non-harmful methods such as reducing window reflection with window film or screens, using decals or paper shapes on windows, installing bird netting or bird spikes, using motion-sensitive sprinklers, removing food and water sources near windows, and using sound repellents. It’s crucial to ensure these methods do not harm the birds. For persistent crow issues, consider professional pest control services.

Why Do Crows Get Attracted to Windows?

Crows are often attracted to windows due to their reflections. They perceive their own reflection in the glass as a threat or a rival crow invading their territory. This can lead to crows pecking or attacking windows. Additionally, these birds are known to be attracted to shiny or sparkly objects, which may also contribute to their interest in windows.

Simple, Non-Harmful Methods to Deter Crows

There are several non-harmful methods to deter crows from windows:

Reduce Window Reflection

Apply window film or install window screens to minimize the reflection that attracts crows. Window screens can prevent crows from getting too close to the window, while window film can make the glass less reflective and more visible to birds.

Use Decals or Paper Shapes

Place decals or paper shapes inside or outside the window to break up the reflection. Collision stickers can help crows recognize the glass as a barrier. Remember to apply them in a dense pattern to cover the entire window surface.

Install Bird Netting

Set up a barrier of netting a few feet in front of your windows to prevent crows from reaching them. Bird netting can be installed a few inches away from the window to prevent crows from reaching the glass.

Use Visual Deterrents

Hang reflective scare devices, such as reflective owl scarecrows or hanging reflector boards, near your windows to scare crows away. Remember to frequently move these around your property to maintain their effectiveness.

Install Bird Spikes

Place bird spikes on window sills or ledges to prevent crows from landing. Bird spikes are a physical deterrent that makes landing and perching uncomfortable for crows.

Use Motion-Sensitive Sprinklers

Install motion-sensitive sprinklers near your windows to scare crows away with sudden bursts of water. This method can be particularly effective as crows dislike being sprayed with water.

Remove Food and Water Sources

Eliminate any food or water sources near your windows that may attract crows. This includes securing trash cans, removing bird feeders, and bringing pet food containers inside.

Use Sound Repellents

Use sound repellents or ultrasonic devices to create an uncomfortable environment for crows. These devices mimic bird distress calls, which can deter crows from lingering in your vicinity.

Products or Tools to Deter Crows

There are several products and tools available in the market that can help deter crows from windows. These include window screens, window film, collision stickers, bird netting, bird spikes, motion-sensitive sprinklers, Acopian BirdSavers, and window decals such as those offered by WindowAlert.

Precautions to Ensure Your Methods Are Not Harmful to Birds

While deterring crows, it’s important to ensure that your methods don’t harm the birds or other wildlife. Use non-harmful deterrents, create an inconvenient environment for crows, remove potential food sources, and avoid using harmful chemicals or toxicants. Using sound as a deterrent, such as playing crow distress calls or using loud bells, can also be effective, but be mindful of the noise levels to avoid disturbing your neighbors or other wildlife.

Role of Professional Pest Control Services

Professional pest control services can provide a solution to deter crows. They use various methods, including habitat modification, exclusion, frightening devices, repellents, toxicants, shooting, and trapping. Some pest control companies that offer crow control services include Trutech Wildlife Service, Terminix, Rentokil, Solutions Pest & Lawn, and Orkin.

In conclusion, there are several effective methods to deter crows from windows. By understanding why crows are attracted to windows and implementing these strategies, you can effectively manage and deter crows from your property.
