What kills Mosquitoes In Standing Water? Check Out This List

In this post, you will find the list of what kills mosquitoes in standing water. Here are seven items that can kill mosquitoes and mosquito larvae in stagnant water.

Is there a yard that does not have stagnant water? This is especially true after rain. Does it exist?

A yard that is wet and dirty with stagnant water is a breeding ground for many pests, including mosquitoes. Mosquitoes love stagnant water; they live in it and thrive there.

These mosquito killers are great for use in all places where you have stagnant water – such as catch basins, gutters, compost pits, and trash cans kept outside.

When you kill the mosquitoes and their larvae in stagnant water (and in your yard), you will dramatically reduce the mosquito infestation problem in your home. Also, you can find in our post 8 Easy Steps To Destroy Mosquito Eggs In The Pool now.


The most underrated yet most effective mosquito killer is kerosene. The best part is that you don’t need to pour gallons of kerosene in stagnant water.

Research by USDA (the United States Department of Agriculture) showed that kerosene is a potent mosquito killer, especially for your outdoors.

To clear stagnant water, you simply need to pour 2-3 tablespoons of kerosene on it. Mosquito larvae and mosquito eggs on stagnant water are instantly killed. The smell of the kerosene all repels the adult mosquitoes.


Kerosene should not be used around swimming pools and flowerpots. You can become ill from consuming kerosene, and it is deadly to emergent vegetation. 

Dish Soap

Dish soap is another lethal mosquito larva killer. It is possible to

Dish soap in water reduces the water’s surface tension causing the mosquito larva to sink in water and die. Dish soap mixed with water also kills fleas.


Do not use dish soap to clean stagnant water near leaking pipes that provide water to your home. But you pour dish soap on stagnant water near leaking pipes that carry water out of your home. 


Often, people ask “will bleach kill mosquitoes and their larvae?”. The answer is yes, bleach does kill mosquitoes.

But it would help if you never use bleach to kill mosquitoes inside your home.

Bleach is harmful to you and your pets. It’s also damaging to your furniture, upholstery, fabric, and wooden floor. It will help if you don’t use bleach on stagnant water near plants either because bleach can quickly kill your plants.

Instead, use bleach in places like catch basins, gutters, rotting woodpiles, and in old tires with stagnant water in it.

How much bleach should you use to kill mosquito larva? You can use 2-3 tablespoons of bleach per gallon of water. That’s sufficient to kill mosquito larvae.

Larvicide Tablets

We don’t recommend kerosene or bleach in stagnant water covering a big and wide area in your yard or garden. It’s because you’ll need them in large quantities, which could be harmful to you and the environment.

If you have stagnant water covering a large area of your yard, you can sprinkle a few larvicide tablets over it.

These tablets work great against mosquito larvae. They’re also safe for the plants but keep them away from your pet and children.

BTI Pellets

The BTI (Bacillus Thurigiensis Israelensis) pellets contain BTI bacteria that infect mosquito larvae and damage their digestive system, so they cannot eat.

In other words, BTI pellets kill mosquito larvae by starving them. BTI pellets can be used easily by dropping them in stagnant water two or three times a month. The stagnant water treated with BTI pellets doesn’t poison the water as kerosene or bleach does. So, it’s safe for pets and plants.

BTI pellets, however, only work against mosquito larvae. It’s ineffective against adult mosquitoes.

Mosquito Eating Fish

Mosquito-eating fish are our favorite as they save a lot of money on mosquito treatment.

If you’ve got a pond or fountain in your yard or garden, then you can put some mosquito-eating fish like koi, guppies, mosquitofish, and gambusia. These fish love to feast on mosquito larvae, and they also eat other pests like mites and beetles.

But refrain from using these fish in a swimming pool. If you’ve added chlorine to the swimming pool, then the fish won’t survive in the pool.

Mosquito Repelling Essential Oil Concentrate

Do you want to avoid mosquito repellents that can be harmful to your pets and plants?

If yes, then mosquito repellent concentrate is a great choice.

Plus, you don’t have to use it daily to get rid of mosquitoes. Using them once in two or three weeks is enough not only to kill mosquitoes in stagnant water but also in your entire yard.

The best part of mosquito repellent concentrates is that they’re pets, birds, and plant-friendly.

And they’re easy to use. They contain essential oils like Geraniol, Rosemary oil, Cedarwood oil, and lemongrass oil that are excellent mosquito repellents.

All you’ve to do is mix 4-6 oz of this concentrate in 1 gallon of water. Pour the mixture into a sprayer. And spray it across your yard and on stagnant water in your yard. That’s it.
