Seagulls leaving a mess on your pier?

Seagulls love a plank dock


Are seagulls leaving their “leftovers” from their meals and potentially harmful “deposits” on your dock daily? Are you looking for a safe deterrent to get rid of them? Here are some suggestions to get rid of them.

Start in Early Spring

You must start in early spring to keep them away. Don’t allow seagulls to roust on your dock. Once established, they will habitually return to the same place each night. Adding deterrents later will have minimal or no effect on them.

What Problems do Seagulls Cause?

Seagulls are noisy, aggressive, and a health hazard to humans. At the same time, they are protected by law in most areas in the US.  

They are highly territorial and aggressive when it comes to food. Under no circumstances should you feed them. They will return time and time again.  It’s like a friend who wanted to stay for just a day or two and never left. 

Remind your visitors not to feed them too. Once one bird finds a source of food, others will follow. 

Don’t leave food containers outside after your parties. Seagulls will continue to return if you do.

What do Seagulls eat?

        Seagull feeding

First and foremost, the seagulls eat fish, rodents, insects, eggs, earthworms, reptiles, plant items, and even other birds. The seagull is a smart bird and very versatile in how they get prey. The food you leave behind is an easy source for them.

Most seagulls breed only once a year and have predictable breeding seasons that last for 3 to 5 months. These large and noisy birds defend their territories from rivals of both sexes through aerial attacks and calls. 

When is their nesting season?

Their nesting season is when they are the most boisterous and the most aggressive.

Seagulls are ground-nesting birds taking live food – crabs, small fish – or scavenge as it becomes available. They historically pose control problems near sources of water or food.

Seagulls are intelligent and resourceful birds that have a highly developed social structure and a complicated method of communication. They even display mobbing behavior – they will attack would-be intruders (like you) and predators when anyone or anything threatens their nest.

How to get rid of Seagulls Humanely

Most of all, seagulls do not like anything that disrupts their flight patterns. Simply put, they do not want to get tangled in anything.

Bird wire is a humane, discreet, and highly-effective control solution for docks. How does it work? This stainless steel deterrent prevents gulls from landing on docks, boats, and other long surfaces that attract pesky birds.

Is there an alternative?

There is another way. Seagulls use a higher UV range than humans to see what’s around them. As a result, they can see underwater without the use of sunglasses like humans require. 

They also “see” a nylon fishing line as a bright line, day or night. That line potentially interferes with their flight, plus it alarms them as it moves in the wind.

Seagulls are heavy birds compared to most birds. As a result, they require a clear path to take off. Try stringing fishing line horizontally about 18″ above the side of your dock. 

It works the same as bird wire and costs much less. The downside to the fishing line is that it needs to be replaced each year and possibly more than once. Hint: string the fishing line from leg to leg and tie it off rather than stringing it the full length in one piece. This way, if one section breaks, it does not take the entire line down.  

Another tip to decrease the likelihood of you breaking the line – cut the hook of a clothes hanger and coil it around the legs of your dock. Leave a “finger” pointing away from your dock with a closed-loop on the end. Secure it about 18″ up and string the line through the loop at the end of the “finger.” It will deter the birds and keep the line far enough away from the dock that you are less likely to break it.

Another deterrent

                   Daddi Long Legs

Daddi Long Legs is another deterrent. It prevents gulls and other large birds from landing in open spaces. Where can you buy this product? Try www.Bird

How it works: Thin, stainless steel rods wave menacingly in the breeze. Any breeze causes the rods to move and interferes with the seagull’s flight as they attempt to land. Benefits: It is a humane product with plastic tips to prevent injury to humans.

In conclusion

Seagulls require frequent attention to discourage them from sticking around.  Remember, DO NOT feed them.  It may look cute or funny, but they will be back frequently along with their debris and leftovers if you do.


It’s best to use more than one means to get rid of seagulls. They don’t like to be disturbed while they eat or sleep, but they can see a single device as non-threatening over time. We recommend that you change or move your devices from time to time. They will adapt over time.
