Keeping geese off your dock involves a combination of visual deterrents, physical barriers, and environmental modifications that make the area less appealing to them. By employing a multi-faceted approach, you can humanely discourage geese from frequenting your dock.
Understanding Why Geese Choose Your Dock
Geese are often drawn to docks because they offer easy access to water, a clear vantage point for spotting predators, and sometimes even a source of food if people feed them or leave scraps. Docks provide a safe, flat surface for resting, preening, and congregating, making them an ideal spot from a goose's perspective.
Effective Strategies to Deter Geese
Successfully deterring geese often requires more than one method, as these birds can be quite persistent.
Visual Deterrents and Reflective Devices
Geese are wary of unexpected movements and bright, flashing lights. Incorporating visual deterrents can make your dock appear less safe or more active than they prefer.
- Reflective Tape: Lining the edges of your dock with reflective tape can keep birds away. The constant shimmer and unpredictable flashes of light created by the tape can disorient and alarm geese, making them hesitant to land or stay.
- Old CDs: If you aren't using your CD discs anymore, they make cool decor. Stringing old CDs together and hanging them where they can catch the sunlight creates a similar reflective effect. As they spin and sway, they cast dazzling, moving patterns that geese find unsettling.
- Reflective Streamers: Streamers are another reflective item you can display to deter birds. Mylar or other reflective streamers tied to dock posts or railings will flutter in the wind, providing both movement and sparkle. This constant activity can prevent geese from feeling secure enough to settle down.
- Predator Decoys: Placing realistic decoys of natural predators like coyotes, swans, or even an owl can sometimes deter geese. It's crucial to move these decoys frequently (daily or every few days) to prevent geese from realizing they are not a real threat.
- Mylar Balloons: Shiny, Mylar balloons can also be tied to dock posts. Their movement and reflective surface can act as a visual deterrent.
Physical Barriers
Creating physical obstructions can prevent geese from easily accessing your dock, forcing them to look for alternative resting spots.
- Low Fencing or Netting: Install a temporary, low-height fence (around 18-24 inches high) around the perimeter of your dock. Geese prefer to walk onto the water rather than fly over short obstacles, so even a small fence can be an effective barrier. Lightweight netting can also be stretched across the dock.
- Stretched Monofilament Line: Stringing fishing line or thin monofilament line a few inches above the dock surface in a grid pattern can make the area uncomfortable for geese to walk or land on. It's nearly invisible, so it doesn't obstruct your view, but it disrupts their ability to move freely.
Auditory Deterrents
While often less effective on their own, sound-based deterrents can complement visual and physical methods.
- Motion-Activated Sound Devices: These devices can emit predator calls, distress calls, or loud noises when motion is detected. Geese can become habituated to repeated sounds, so varying the sounds or using them intermittently is key.
- Wind Chimes: Larger, louder wind chimes can create unexpected noises that may discourage geese, especially if they are placed strategically to maximize sound with wind.
Habitat Modification
Making your surrounding environment less inviting to geese can reduce their overall presence in the area.
- Remove Food Sources: Ensure no food scraps, bread, or birdseed are left on or near your dock. Geese will quickly learn to frequent areas where food is readily available.
- Keep Surrounding Grass Long: Geese prefer short grass for grazing and clear sightlines to spot predators. Allowing the grass around your dock and shoreline to grow longer (6-8 inches) can make the area less appealing for them to graze and congregate.
- Discourage Nesting: Regularly inspect your dock and surrounding areas for any signs of nesting attempts, especially during early spring. Removing nesting materials before eggs are laid can prevent geese from establishing a territory, but always check local regulations regarding wildlife before disturbing nests or eggs.
Important Considerations for Geese Deterrence
- Be Consistent: Geese are intelligent and will test new deterrents. Consistency in applying your chosen methods is crucial for long-term success.
- Combine Methods: A multi-pronged approach, combining visual, physical, and environmental strategies, is typically the most effective way to deter geese.
- Humane Approaches: Always prioritize humane methods that focus on deterrence rather than harm. The goal is to encourage geese to move elsewhere, not to injure them.
- Check Local Regulations: Before implementing any geese deterrence strategy, always verify compliance with local, state, and federal wildlife protection laws. Geese are often protected species.

Summary of Geese Deterrence Methods
| Method Type | Specific Tactic | How It Works |
|---|---|---|
| Visual Deterrents | Reflective Tape, Old CDs, Reflective Streamers | Flashing lights, movement, and reflections disorient and alarm geese. |
| Predator Decoys | Creates the illusion of a threat, but requires frequent movement. | |
| Physical Barriers | Low Fencing or Netting | Blocks walking access, as geese prefer to walk onto water over obstacles. |
| Stretched Monofilament Line | Makes walking and landing uncomfortable without being highly visible. | |
| Auditory Deterrents | Motion-Activated Sound Devices | Emits disturbing noises or predator calls when activated. Varies effectiveness. |
| Habitat Modification | Remove Food Sources | Eliminates incentive for geese to visit. |
| Keep Grass Long | Makes the area less suitable for grazing and reduces clear sightlines for geese. |
