Bleach can be an effective way of killing mosquito larvae. Yet, it’s a method that has serious drawbacks. Mainly the bleach can affect the environment in which the larvae are found. Also, it has the potential to kill off other organisms in the area.
Mosquitoes can ruin your time out camping in summer, or that late evening BBQ when the weather warms up. Wouldn’t it be great if you could get rid of them? No more constantly swatting at the air to chase them away. No more annoying bites that itch for days.
It might sound heartless, but if you kill mosquitoes when they are young, then you are reducing the population. They can’t mature and then produce more mosquitoes. A female mosquito can lay 300 eggs. That’s a lot of bloodsuckers waiting to grow up.
Read on to find out if you should use bleach. We will also provide you with alternative ways to destroy mosquito larvae.

When using bleach to kill mosquito larvae, you need to consider the location in which the larvae are.
Pouring bleach into a pond, pool of water, creek, or other waterways can harm other creatures living in the water.
The ideal use of bleach is in situations in which the mosquito larvae are isolated from other fish or water-based inhabitants. For example, in your gutter, or in small pools of stagnant water. You only want to kill the larvae and nothing else.
With that precaution in mind, let’s take you through how to use the bleach.
You don’t need to doubt that bleach will kill the larvae, it’s guaranteed.
Take a gallon of water and mix in a tablespoon of bleach. Pour this solution into the area where the larvae are.
It’s as simple as that. The larvae are dead.
How long does it take to kill the mosquito larvae?
One study looked at the effectiveness of different dosage strengths of bleach on mosquito larvae. The larvae were confined to tires and the bleach was applied.
2 tablespoons of bleach added to 5 liters of water was enough to kill the larvae. However, within two weeks pupae started to appear. To reduce the number of these pupae, additional doses of bleach were required. What that means is that you may need several applications of bleach to the area where you discovered your mosquito larvae.
We mentioned that using bleach can have unwanted consequences to the local environment as well as other creatures that live in the water.
To avoid destroying nature, there are alternative ways to kill off mosquito larvae.
The only issue with this method is that it shouldn’t be used in areas that contain fish. If coated with the oil the fish can suffer from dehydration, hypothermia, or starvation. There’s also the possibility that the oil could lead to the fish sinking.
If there are no fish present, then go ahead and apply the oil. Add a teaspoon of it to the water. The mosquito larvae will die.
These are shaped like a donut and contain mosquito-killing bacteria, bacillus thuringiensis israelensis (BTI). The BTI will attack nothing but the mosquito larvae, so makes an efficient way to kill off the larvae while protecting the other water-dwelling organisms.
One dunk is enough to remove larvae from a 1002 foot radius and they last for a month. Place it in the water and say “Goodbye” to the larvae.
Mosquitoes love stagnant water that is abundant with food (algae). The nutrients within the algae help the larvae can grow and mature.
You can destroy this mosquito enticing environment by having a constant flow of water pass through the area.
If you have a small pond, introduce a fountain or water pump.
Living near a naturally produced area of stagnant water? Consider ways in which you can have fresh water entering the area. This will require you to seek permission from your local authority. You just can’t go and start diverting water!
You may already have fish in your pond, but they may not be so keen on feasting on mosquito larvae.
Goldfish, carp, and mosquitofish placed into your pond will eliminate the problem. They love to snack on baby mosquitoes.
Some people choose to have Koi fish, which is a variety of carp from Japan. You’ll need to contact your local government or Environmental Protection Agency office to see if you can have Koi as they may be a banned species.
Mosquitoes feed on algae and bacteria. If you don’t keep your property clean and tidy, you open the potential for the mosquitoes to come.
Keep them at bay by eliminating the food sources. Give your pond or other water features a regular clean. Scoop away any scum that forms on the surface of the water.
You have a couple of advantages with Apple Cider Vinegar: it acts as a mosquito repellent and kills mosquito larvae.
To get rid of the larvae use a vinegar to water ratio of 15:85. Mix the vinegar and water and then pour it into the water that contains the larvae. They will die within the next 24 hours.
Of course, it depends on the strength of the vinegar. Dilute it too much and you may find that it isn’t that effective.
As a mosquito repellent, pour some of the vinegar-water solution into a small spray bottle. Then spray your exposed skin and the mosquitoes will stay away.
Use a couple of drops of dish soap for every gallon of water in which the mosquito larvae are. That will be enough to kill them.
You can substitute the dish soap with shampoo if you like.
We mentioned more natural ways in which you can kill mosquito larvae. Yet, you may be wondering if using a pesticide is okay.
Pesticides can certainly take care of the problem, yet there is still the environmental impact to consider. That’s because pesticides can contain methoprene which, though it has a low level of toxicity, can harm other organisms within the water.
If the methods of ridding yourself of a mosquito infestation seem overwhelming, or the problem is bigger than you can handle, get help from the professionals.
Exterminators have the equipment and the knowledge to solve the problem. Do a search on the internet for an exterminator in your area or look up the contact details in a local phone directory.
