How To Get Rid Of Mosquito Larvae In Your Pond Or Pool

Mozzies are a real pain in the a**, and pretty much every other part of your body that you can mention. I remember being eaten alive on my first visit to Australia. In this article I'm going to give you some great strategies for how to get rid of mosquito larvae in standing water such as ponds, dams, water tanks etc.

There are the four stages of mosquito life cycle; egg, larva, pupa and adult. In the larva stage, the mosquito prefers to live in stagnant water for the 14 days of this cycle stage. This might be that pond pool, rain barrel system or open water tank near your house. 

At the larva stage mosquitoes can neither fly nor bite, they only carry with them bacteria that cause disease. They are however food to fish in the water.

At this stage dealing with mosquitoes is relatively simple. There are several ways to get rid of the mosquito larvae in your pond or pool. Let's dive into them.

Quick Checklist:

  • Try To Create Water Movement Using A Pump Or Water Feature
  • Check Your Property For Standing Water
  • Eliminate Mosquito Food Sources Like Animals And Pond Plants
  • Keep Vegetation Pruned Close To Water Edge
  • Increase Fish And Other Predator Populations
  • Keep Still Water Bug Free With These Tips

There is often no escaping some standing water on your property, especially if you have a pond or large body of water on your property.  But, many people have standing water on much smaller scales, and much can be done to prevent mosquitos in these areas.

This video is important to help us understand the life cycle of a mosquito. It's only 3 minutes long but is really an excellent insight.

Before we go onto some specific mosquito treatment for standing water, let's discuss some ways to minimize the problem for non-pond/lake situations.

How To Get Rid Of Mosquito Larvae In Your Pond Or Pool - Tips And Solutions

Eliminate Standing Water From You Immediate Home Area

This is not always simple, but taking steps to make sure that wheelbarrows are overturned and not allowed to fill with water, that tarpaulins covering log piles are prevented from allowing water to sit on them, to making sure that gullies and drainage is on good order, will all help prevent breeding grounds for mozzies.

Ponds are a problem that it's hard to overcome, but rain butts can be mosquito-proofed by ensuring lids are a good fit and there is no way the little blighters can get access.

Additionally, keeping gutters clear so water can drain is another stellar idea.

What Kills Mosquito Larvae In Standing Water?

Stagnant water is a breeding ground for mosquito larvae. This pond looks wonderful with it's grasses and lilies, but under the surface mosquito larvae may be growing

Mosquito Treatment For Standing Water

Organic Mosquito Dunks

There are plenty of ways to kill mosquitos in standing water including mosquito dunks. This 20 pack on Amazon is cheap as chips and one dunk covers 100 square feet of water. Ideal for ponds, feed troughs, bird baths and rainwater barrels. These  are harmless to humans, animals and fish, but are super effective and killing mosquito larvae in ponds or other stagant water.

Mosquito dunks contains Bacillus Thyuringti-ensis Israelensis (BTI), a substance that is very toxic only to larvae.

Summit 20-Pack Mosquito Dunk

The BTI is a delicacy for the Mosquito larvae thus used as a bait to kill them. As recognized by the United States Environmental Protection Agency it is very safe for organic gardening.

When you apply it on already infested water, one dunk treats 100 square feet water surface it takes only the first four hours to get rid of the existing larvae and keep the water free from new entrants. Mosquito dunks break downs slowly while it floats on top of water for thirty days.

Home Remedies For Mosquito Larvae

Mosquito Bits

Mosquito Bits are similar to mosquito dunks except that they are in pellet form. they are effective in non-draining water. You should apply it in the ratio of one teaspoon of mosquito bits to 25 square feet of non-draining water; applied evenly on the surface area 


Apart from desserts, medical products or even cosmetics, cinnamon are used to kill mosquito larvae in a very environmental friendly yet highly effective practice.

When you apply cinnamon in the ratio of 15% cinnamon oil to 85% water, it does not only guarantee you protection from mosquito larvae but also gives your surrounding a yummy smell.


We use bleach for whitening our fabric and sanitizing our tools but the Environmental Protection Agency (EPA) has also identified the application chlorine bleaches that contain 5.25% sodium hypochlorite as the active ingredients as another weapon for destroying the mosquito larvae. 

This method is however not 100% environmental friendly as bleaches are harmful to pets and wildlife. To get rid of the larvae, you should apply it in the ratio of 1 tables spoon bleach to 1 gallon of water. 

You can also make a solution of one to one of bleach and water then spray it in the compound for one week to eradicate mosquitoes in case you have just emptied your water containers.

We should use bleach as our last resort for this type of pest control, only if we have proper protection for our wildlife and water sources from run off.

Apple Cider Vinegar

A ratio of 15% Apple Cider Vinegar to 85% water is a completely non-toxic way to get rid of mosquito larvae in our surrounding.

The mixture should contain enough; or more than enough vinegar when in doubt as lower concentrations don’t kill. Putting excess has no harm as vinegar is environmentally safe.

Bragg's Apple Cider Vinegar on Amazon is one of the best you can buy. Great for your health and bad for mosquitos. If you don't intend to use it in the kitchen, a cheaper brand will probably suffice.

Bragg Apple Cider Vinegar, 1 gal/128 oz.

Soap and Shampoo

Most common type for gardeners is the insecticidal soap found in hardware stores. However, any soap is effective in killing mosquito larvae. 

You should mix the solution is a ratio of one milliliter of liquid soap to one gallon of water kills mosquito larvae or simply a dish of soap or shampoo and apply it in stagnant water for two days.

Using Oil To Kill Mosquito Larvae

We can use one teaspoon of oil per gallon water to create a thin coating on top of the water which then. this suffocates the Mosquito larvae and eventually kills them. 

This method is however harmful to other water inhabitants like fish and should be applied with caution. we can be used any type of oil be it mineral, light horticultural, neem, or vegetable oil. Add 1 tbps per 100 square meters, and it will spread out and suffocate mosquito larvae. 

This Neem oil on Amazon looks like a winner.

Be aware that the oil on water method can kill other small creatures that need to breathe at the surface.

It is the larvae that grows into an adult in the life cycle of a mosquito. It is at this phase that we have the easiest task in the entire when dealing with mosquitos. 

Using the above methods, we can get rid of mosquito larvae from our homesteads and environments.While some are very eco-friendly, others have great negative effects to our wildlife and pets in our homestead thus we should practice them with caution.

Last Word

Mosquitoes are an inconvenience for sure. I got eaten alive on my first visit to Australia back in 2001. Why do they always go for your feet? I scratched mine till they bled to get some relief.

But mozzies are also carriers of disease, and keeping them from breeding close to your home is vital. I hope these few tips and home remedies for mosquitoes can give you a starting place to try a few things and see what works.

Good luck!
