Do Ducks Eat Water Hyacinth? (Explained)

Keeping a pond or lake pristine requires a lot of hard work. In the case of water hyacinth, however, all that work may be for naught. This aquatic weed thrives in warm, slow-moving water and has been known to overrun ponds and lakes almost overnight.

It’s an invasive plant that has been known to destroy ecosystems and drive native species to extinction. If you have a small pond or lake on your property, it’s important to know if ducks will eat water hyacinth in order to prevent it from spreading.

If you are considering adding ducks as part of your eco-friendly pond management plan, knowing if they eat water hyacinth is critical information.

Ducks do eat hyacinths, they are omnivores and feed on seeds, aquatic plants and algae. If you have a pond that is filled with hyacinth, you may want to introduce ducks to help you manage the mess.

However, eventually, you may need to take matters into your own hands.

What is Water Hyacinth?

Water hyacinth is a flowering plant that thrives in slow-moving water. It is native to tropical areas of South America but has become a major problem in other parts of the world.

This aggressive, invasive plant is known to grow in lakes, ponds, rivers, and other bodies of water. The stems can grow up to 3 feet long and produce round, blue-green leaves that are about 2 inches across.

The flowers are pink or purple, while the roots are thick and white. The plant thrives in warm water with low levels of nutrients. It can grow under a wide range of temperatures and can even survive in brackish water. It’s also shade tolerant, which makes it a difficult plant to control.

The seeds are light and easily carried by the wind, as well as on the feet and feathers of birds.

Why Is It Problematic?

Water hyacinth is a serious problem for water ecosystems. It grows rapidly and can produce about 1,000 new plants each week.

Left unchecked, the plant can completely take over a lake or other large body of water. The plant can also block waterways, causing problems for shipping and the fishing industry.

Worst of all, the plant can drive other species to extinction by taking over their habitat. In some parts of the world, water hyacinth has been linked to outbreaks of mosquito-borne diseases like malaria.

It can also cause damage to the fishing industry by clogging nets and creating obstacles for boats. It can even disrupt drinking water, as the plant can clog intakes at water treatment facilities.

Will Ducks Eat Water Hyacinth?

If you have a large pond or lake on your property, there’s a chance water hyacinth will grow there.

Fortunately, there are a number of ways to control and remove the plant. Insects and other small pests can help keep the population in check, but you’ll also need to remove the plant from the water when possible.

Ducks will eat almost any plant that is smaller than their beak, and hyacinth is definitely on the menu.

This plant is actually quite nutritious for them since it’s rich in fiber and quite high in proteins, so they will not only help keep the pond clean but also enjoy a good snack.

What Do Ducks Eat In Ponds?

Ducks are omnivores, which means they eat a wide variety of foods. While they do enjoy eating water lilies, they also enjoy munching on other pond plants (water lilies, watercress), insects, worms, and fish.

Ducks will eat just about anything they can get their beaks on.

They are also messy eaters, so they will often leave behind messy piles of mud and algae.

If you want to keep flowers in your pond for decoration, the best way to do that is to grow aquatic plants that ducks don’t like to eat.


Ducks will eat water hyacinth, but only in moderation. This plant is invasive and will disrupt an ecosystem if it’s allowed to take over, so it’s very important to keep an eye on your water to prevent this.

There are a number of ways you can control the plant, and letting your ducks handle it is one way to deal with the problem.

This plant is safe and healthy for them to eat, so you don’t have to worry about potential repercussions.
