Title and description
Almost all aquarists who care for their ornamental fish and buy or independently obtain live food for them are familiar with mosquito larvae. They are called bloodworms, which look like small worms. The color of the larvae depends on the type of mosquito:
- black or brown - in the squeak mosquito;
- green - malarial;
- red ones are at the bell.
Such creatures are born from mosquito eggs laid directly in the water. Typically these are shallow fresh water bodies, ditches, large puddles, rainwater pits or containers.
The size of the larvae at birth is 1-2 mm, during growth it can reach up to 1 cm. The chest part is slightly wider than the abdomen, there are 2 black eyes on the head, as can be seen in the photo of mosquito larvae. At the end of the body there is a process - a breathing tube through which the creature breathes, which is closed by a special valve.
Interesting!
Throughout the body there are bristles with which the larva swims and moves in the water, called swimming hairs. The longest of them is located near the tail, playing the role of a “rudder” and a “motor”, which allows you to change the direction and speed of swimming.
In order to breathe, the worms stand with their tail up on the surface of the reservoir, absorbing oxygen from the air, and then swim further. Mosquito larvae are in the water all the time, but can dive deep for no longer than 15 minutes, as long as there is a supply of air.

Nutrition and lifespan
The larval stage of mosquitoes lasts 3-4 weeks, its duration depends on temperature and other environmental conditions. During these days, she manages to shed several times, shedding her exoskeleton and gradually increasing in size. The permissible temperature for the normal development of mosquito larvae is in the range of +10-+35°C, while the optimal temperature is +25-+30°C.
Interesting!
Along with the length, as the larva grows, its weight also increases: according to biologists, it increases 500 times in 20-30 days.
Their main food is small living creatures and microorganisms found in the reservoir: unicellular algae, decomposing plant organic matter. To obtain food, the larva filters 1 liter of water per day, which is quite a lot for such a small living creature.
The next stage of mosquito development, the formation of the pupa, occurs after the transformation of the larva itself and is a more complex creature.
Enemies
Most mosquito larvae die for various reasons:
- due to bad weather conditions: natural disasters, low temperatures;
- they are eaten by natural enemies, including the inhabitants of the reservoir: fish and amphibians, for which they are the main food;
- due to unfavorable ecology: polluted water, oil film on the surface, which prevents them from breathing.
On a note!
However, the decrease in number due to death is compensated by the high fertility of mosquito females, so people can only dream of reducing their population.
Types of larvae and mosquitoes
Mosquito larvae
The structure of the body and important organs of different species of such creatures may differ, as well as their behavior.
Malarial
The larvae of malaria insects (anopheles) have a large head with oral brushes for food, a large chest and an abdomen of several segments. Unlike others, they do not have a respiratory tube at the tip of the abdomen, but have special spiracles in the 8th segment on the sides of the body. Their life passes near the surface (and they try to stay parallel to it), where they breathe and feed, catching small organisms with special brushes and directing them into their mouths.
Bell mosquito: harm to humans
Unlike blood-sucking mosquitoes, the mouthparts of bells are designed in such a way that they are not able to pierce their skin and drink blood, so bells do not bite. Regular mosquitoes drink blood only to reproduce. Bell bells do not have such a need; they reproduce independently of humans or other living creatures, so they do not consider you and your pets as a source of food. If you are bitten by an insect that looks like a mosquito, it means it is not a bell, but someone else.
The bell mosquito is incapable of causing physical harm to humans, but is capable of irritating, disturbing and creating everyday problems:
- Flicker, get into eyes, mouth and nose.
- Sit on the skin, provoke an itch, drive it away or slam it, cause an unnerving feeling that someone is constantly crawling on you.
- Contaminate decorative garden ponds and reservoirs.
- Clogging sewers and drains.
Sometimes the number of bells can be so large that insects flying out of the water cover the walls of buildings, stick to the windows of houses and cars, and enter rooms en masse.
The flight of bloodworms lasts several days, but in one summer there can be several flights, most often from 3 to 5. If you do not want to use bloodworms for fishing purposes and as food for reptiles or fish, bell mosquitoes can be destroyed with special chemicals yourself or seek help from the SES.
Benefits and harms of mosquito larvae
The development and activity of mosquito larvae are not only interesting and original, but also benefit fresh water bodies by filtering water. They are also nutritious food for fish and are used by humans for fishing. By their presence, you can determine the cleanliness of the reservoir, because when they become polluted, they die.
The only pests among them are the larvae of centipedes, which, due to their feeding preferences, harm agricultural crops by gnawing on soft, succulent roots and seedlings of agricultural crops.
Bell mosquitoes: how to get rid of them
Regardless of which destruction method you choose, use preventive measures.
- Compensate for excessive moisture in the entire area or its individual zones through drainage, changing the composition of the soil, bulk beds or other methods of draining the area.
- Clean and care for decorative ponds, change the water in them from time to time.
- Carry out preventive cleaning and disinfection of sewers, drains and drainage systems.
Means for killing mosquito larvae will help get rid of bloodworms, such as:
- Dobrokhim Micro
- Averfos
- Maxifos
- Xulat
- Chlorophoska
- Avicin
Before using any product, read the instructions for use and follow them strictly.
If you have mosquitoes, pest control is the fastest and most effective way to get rid of them.
- Treatment in most cases is done in 1 day and takes from 1 to several hours, depending on the area.
- High-quality products are selected according to the situation so that the procedure is not only effective, but also safe.
- The service can be scheduled for a date convenient for you or provided urgently.
In the SES "Des Group", certified by Rospotrebnadzor, with more than 7 years of experience, you can order the treatment of reservoirs, plots, territories and sewer systems from bloodworms and bell mosquitoes, as an individual, company or organization.
