Mosquito larvae in water

5 minutes. for reading

If you have a suburban area with a personal pond, a swimming pool, or you simply store barrels of water on your territory, then sooner or later you will be faced with an invasion of well-known blood-sucking insects - mosquitoes. These creatures actually lay their larvae in the water, causing a lot of inconvenience to site owners.

How dangerous is a mosquito?

Everyone knows that mosquitoes leave many bites on the body that cause unbearable itching. However, this is not the only problem. Mosquitoes can carry a variety of diseases, many of which can pose a threat to human health and can even be fatal. Therefore, if mosquito larvae are found in water, it is recommended to immediately begin their destruction.

Where does a mosquito come from on your property?

All types of mosquitoes are nomadic creatures, constantly seeking places with excess moisture and heat necessary for hatching larvae. Therefore, upon discovering stagnant water, they immediately head to this area. Scientists have confirmed that a female mosquito does not require a large body of water to lay larvae. Statistics indicate that she only needs about 3 cubic centimeters for this process.

The life cycle of mosquitoes is essentially impossible without the blood of people, and therefore they constantly strive to find a new source of food to continue their species.

Where can a mosquito settle and lay larvae?

  1. Water in barrels and other containers.
  2. Deep surfaces that retain moisture after rains.
  3. Any puddles.
  4. Swimming pools.
  5. Ponds and lakes.
  6. Bowls for pets living outside.
  7. Accumulations of wet debris on the site.

After breeding, the female mosquito begins to lay eggs, and their number depends on the volume of blood drunk. Some types of malaria mosquitoes can lay at least 250 eggs at a time.

Most often, female mosquitoes choose the surface of the water to lay eggs. To do this, they need a standing body of water with water at a certain temperature, which makes ponds and artificial reservoirs excellent places for this process. Sometimes female mosquitoes can lay eggs on land, but for this the soil must be well saturated with moisture.

Mosquito larvae can also develop on objects floating in water. Female mosquitoes avoid ponds with fish, since the fish actively eat newborn mosquitoes and can easily destroy all the larvae.

Life cycle of a mosquito

Mosquito larvae appear a few days after the female lays eggs and resemble small worms in appearance. Interestingly, the larvae of some species of mosquitoes, such as bloodworms, are used in fishing and are called “fishermen’s moths.”

Mosquito larvae are forced to frequently rise to the surface of the water to breathe and search for food, as they are heavily dependent on access to air. For example, bloodworms, which usually live in coastal mud, also rise to the surface of the water to breathe.

The mosquito larval stage involves four molting stages, during each of which they shed their armored exoskeleton to grow.

After the larva turns into a pupa, its behavior and nutrition remain similar to the previous stage. However, the pupal organism becomes more complex. Scientists say that mosquito pupae turn into adults in about 5 days.

Adult mosquitoes, after turning into pupae, acquire a darker color. Male mosquitoes typically live for about 21 days, while females can live up to three months under favorable temperature conditions. Otherwise, their life cycle is shortened.

Methods for getting rid of mosquito larvae in water on the site

There are several effective methods for getting rid of adult mosquitoes and their larvae in water bodies. The main ones are listed below:

  1. Keep your water bodies clean: Regularly monitor the condition of the water in various tanks. Avoid stagnant water and keep the pool closed when not in use.
  2. Use Chlorifix: If mosquito larvae have already appeared in the water, you can use Chlorifix. Follow the instructions for use and the larvae should die within a few days.
  3. Apple cider vinegar for watering barrels: If your watering barrel is infested with mosquitoes, use apple cider vinegar. Just add one or two tablespoons of vinegar to the barrel and the mosquito larvae will be killed.
  4. Vegetable oil and essential oils: Vegetable oil, floating to the surface of the water, creates a film, suffocating mosquito larvae. You can also use various essential oils.
  5. Garlic protection: Crushed garlic mixed with water creates a repellent odor, preventing mosquitoes from laying larvae.

These methods provide varied and safe ways to control mosquitoes and their offspring in aquatic environments.


If you don’t trust traditional methods, you can always use proven chemicals. Many of them not only effectively destroy larvae in water bodies, but also prevent further egg laying.

Larviol is an excellent mosquito repellent. Its effect begins immediately after mosquito larvae ingest the drug. At the same time, Larviol is absolutely non-toxic and remains in water for a long time, completely safe for people, fish and pets.

This mosquito repellent product comes in the form of a suspension. The required amount of product is dissolved in water, then carefully filtered and poured into a body of water where insect larvae live. It is known that the effect of Larviol lasts from 10 days to a month.

A similar effect against mosquitoes is provided by Bacticide, which is available in powder form. The powder contains bacteria that are activated during the digestive tract of mosquito larvae and cause complications leading to the death of the larvae within a few days.

How to get rid of mosquito larvae in water?

There are several ways to control mosquitoes in water, the simplest of which is to deprive the mosquitoes of their ability to breathe. To do this, it is enough to create a special film on the surface of the water, for example, by adding a few tablespoons of oil. After about a day, all the mosquito larvae in the water will die and the problem will be eliminated.

How do mosquitoes lay larvae?

Mosquitoes use two main methods of laying larvae. The first involves laying each egg separately, the second - laying a whole set of eggs. One female can lay approximately 150 eggs with larvae at a time. The speed of their development depends on environmental conditions, primarily on the temperature level. Growth time varies from 2 days to more than a week.

How do mosquitoes breed in water?

How mosquitoes reproduce can vary depending on the species, but most often the process follows a specific pattern. Females mate with males and then lay eggs either directly on the water or on plants nearby. Then begins the laying of eggs and several stages of their development, from egg to pupa, and then follows the transformation into a mature individual.

What do mosquitoes do in water?

In water, these blood-sucking insects lay eggs and then hatch offspring. Mosquitoes spend most of their lives in the aquatic environment, becoming land insects only at the most mature stage of their development.
