Wondering how to kill mosquitoes in pond? We have you covered! It may seem harmless due to its size but a single bite of a mosquito can lead to various deadly diseases including dengue, malaria, and zika. These annoying insects rest in tall grasses, weeds, and bushes and fleet towards buildings and houses to feed themselves. Mosquitoes breed in fresh stagnant, standing water often found outside homes and buildings - in containers, ponds, buckets or cans.

Even though most male and female mosquitoes feed on plant juices and nectar, some species have a developed mouthpart for the female mosquitoes.

Why Are There Mosquitoes in Your Pond?

As mentioned earlier mosquitoes breed in stagnant water. Larvae need water to develop into full-grown mosquitoes. They are highly adaptive and can easily germinate even in the sparse amount of standing water. Therefore, if you are wondering why there are mosquito larvae in your pond, you finally have an answer! Killing larvae in a pond is undoubtedly one of the foolproof ways of getting rid of this nuisance once and for all.

Effective Ways to Kill Mosquitoes

If your pond has become a breeding ground for mosquitoes you may want to experiment with different methods. Although it may seem like a tough job to do, getting rid of this nuisance is quite easy. So, let’s have a look at how to kill mosquitoes in pond water and make sure you never encounter them again!

1. Create Movement in the Water

Female mosquitoes look for stagnant water with algae and bacteria to lay the eggs. The larvae survive in such an environment rich with nutrients until they turn into a full-grown mosquito and the cycle continues until you intervene.

To stop this cycle introduce water movement to your pond with the help of pumps or aerators. Not only these will create movement but also add oxygen to your pond.

Another effective way to create movement and keep mosquitoes away is to add decorative pond spitters which not only add beauty to your pond but create movement as well.

You just have to drop one dunk into the pond and leave everything else to it. These dunks contain a bacteria that is harmful to the larvae and starts to work within an hour. One dunk can last up to thirty days

4. Bleach

However, if you do not have any fish in the pond add an appropriate number of bleach tablets into the water. As the tablets dissolve, they will kill the larvae and get rid of the nuisance.

6. Oil

A light coating of oil on the surface of water suffocates the larvae and kills them quickly. You can use olive or vegetable oil for this purpose. Add one teaspoon of oil into one gallon of water and pour it into the pond. Make sure this method is used only if there is no fish in the pond.

7. Mosquito Bits

These are just like mosquito dunks but smaller in size. They help to treat a small area of standing water and can be added to the water in the same way dunks are added. Replace them after every thirty days to get a mosquito-free pond.

Ensure you have a pond filter that filters the water of the pond from time to time and prevent algae from growing back.
