Species, storage locations and control methods

the essentials in brief

• Mosquito larvae go through four stages of development and live predominantly in water.
• Massive occurrence makes mosquito larvae an important part of the food chain, primarily for fish and birds.
• Red, white and black mosquito larvae serve as fish food in ponds and aquariums or are the target of control measures in the garden and home.

Portrait of red mosquito larvae - natural treasures and a source of food

Red mosquito larvae are masters of adaptation, clever survivors and mostly live in water. The filigree, slender larvae are rich in important nutrients and live in huge schools. These attributes make red mosquito larvae valuable natural treasures and an inexhaustible source of food for fish. Midges hatch from red mosquito larvae and have a lifespan of a few days. In contrast to some conspecifics, mosquitoes do not bite or suckle blood. The following portrait summarizes important information about red mosquito larvae:

Appearance and habitat - profile

Red mosquito larvae are the offspring of mosquitoes that gather in huge swarms for a wedding dance. After mating in the air, the females drop numerous eggs over the surface of the water or attach small packets of eggs to the bank. The insects don't have much time to start a family, because dancing mosquitoes only live for a few days as imago. Red mosquito larvae hatch from the eggs. The following profile sums up important identifying features and preferred habitats:

• Body shape: slim, worm-shaped with head capsule and distinctive mouthparts
• Composition: 3 breast segments with 1 pair of stumpy feet in front, 9 abdomen segments with pusher
• Color: red (use of hemoglobin for oxygen supply)
• Movement rhythm: snaking
• Main habitats: standing and flowing water with fresh or salt water, less often bank substrates
• Nutrition: algae and suspended matter, floating leaves, empty larval shells
• Thermal resistance: heat-resistant up to 51 ° Celsius and frost-resistant

The vast majority of the 570 species of mosquito known in Central Europe practice a clever survival strategy in the larval stage. Red mosquito larvae live in self-made tubes to protect themselves from predators. In the protection of these webs, the caterpillars complete a total of four larval stages until they settle for a few Days pupate, hatch as finished mosquitoes and lift up into the air as light as a feather for a wedding dance.

Purpose in life and possible uses

Red mosquito larvae are a treat for fish

Red mosquito larvae are a coveted delicacy for fish. A wide range of species ensures replenishment at any time of the year. There are early spring types (March / April), spring types (April / May), summer types (June / July) and autumn types (September / October). The main hatching time is in summer, when mosquito larvae are most urgently needed as a food source. The larvae often attach themselves to the surface of the water with their tubes, which makes them easy prey. Not only amphibians make use of the abundant food source, but also domestic birds and migratory birds.

Owners of fish ponds, aquariums and terrariums have not missed the benefits of the mosquito larvae. For this reason, red mosquito larvae are dried or can be bought as frozen food in most specialist shops and on the Internet.

Differentiate mosquito larvae by color

In the realm of mosquitoes, joy and sorrow are close together. Mosquitos, in particular, make life hell indoors and outdoors when the beasts are after our blood. Good to know that the color of mosquito larvae reveals which mosquito species will hatch after pupation. The following table explains the differences:

The above portrait sheds light on the high level of appreciation for red mosquito larvae. Black mosquito larvae, on the other hand, cause ambivalent feelings in people because they transform into the hated mosquitoes. Of course, this does not matter to the fish in the pond and aquarium, because they eat the larvae regardless of the species they belong to. White mosquito larvae represent the minority among native species and are less common in the wild than red and black larvae.

Mosquito larvae in the pool - what to do?

Visually, mosquito larvae have little in common with mosquitoes

A pool magically attracts female mosquitoes to use the inviting surface of the water as a place to lay eggs. Within a short time the pool is teeming with mosquito larvae, which spoil the joy of swimming. Without countermeasures, hosts of mosquitoes hatch and hunt human blood donors. You can put a stop to this audacious hustle and bustle by combating mosquito larvae in the pool. The following methods have proven themselves in practice:

• Remove mosquito larvae with a pool vacuum
• Alternatively, destroy mosquito larvae with a filter pump, ideally a sand filter system
• Home remedies for killing mosquito larvae: Add detergent to the pool water

As a preventive measure, we recommend covering the water with a pool tarpaulin after every swim. The installation of is more attractive for the appearance of the pool and just as effective in prevention Water games. Mosquito larvae have little chance of survival if the water surface is constantly in motion. In addition, we recommend that the pool chemistry in the eye to keep. Primarily the pH value should be checked regularly. Values ​​below 7.2 and above 7.6 are regulated with adequate pool products.

Breeding mosquito larvae yourself - how does it work?

Financial considerations are not in the foreground when fish pond owners or aquarists decide to breed mosquito larvae themselves. You can buy red mosquito larvae dried or as frozen food at an affordable price. The most important motive for breeding are the controlled framework conditions from which mosquito larvae emerge. Purchased mosquito larvae always harbor the risk of being contaminated with parasites or pollutants. We looked over the shoulder of experienced aquarists and found out the following options for breeding mosquito larvae:

• Fill the tub or tub with water, set it up outside so that female mosquitoes can lay their eggs
• Check out rain barrels with friends, skim off swimming mosquito larvae, spread them in the water barrel at home
• Collect mosquito eggs in water yourself, let them grow into mosquito larvae in a water bucket
• Important: Cover the vessel with an insect net or old silk stockings to prevent it from escaping

All options come with a lot of effort and a variety of risks. Red mosquito larvae often protect themselves as flying mosquitoes with self-spun tubes until they hatch. In order to get to the larvae as live food for fish, the tiny quiver has to be removed in advance with great care. Simply collecting mosquito eggs and larvae from unfamiliar waters without the permission of the owner can have legal consequences.

Fighting mosquito larvae - tips & tricks

Objects in which water remains should be removed

In water-rich regions, cities and municipalities deploy heavy artillery to combat mosquito larvae before they turn into stinging pests. Only the association “Municipal Action Group to Combat Mosquito plague "around four million euros every year to kill up to two trillion mosquito larvae destroy. The focus is on black mosquito larvae that mutate into the dreaded mosquitoes. Hobby gardeners can benefit from the experience gathered by the experts to effectively combat pests both indoors and out. We have put together practical tips & tricks for you below:

Fight mosquito larvae outside

A proven means of combating mosquito larvae comes from the realm of bacteria. Bacillus thuringiensis israelensis was discovered in the mid-1970s for the biological destruction of mosquitoes in the larval stage. It is a subspecies of the Bacillus thuringiensis bacterium and has been used as a biocide ever since. The bacteria can kill mosquito larvae in the water within a short time without causing damage to other animals or the environment. Neudorff mosquito-free is one of the top products on the market with this active ingredient and approved for use in home and allotment gardens. How to use the agent knowledgeably:

1. Buy biocide in tablet form
2. Use rain barrel: crush 1 tablet in every 50 liters and stir in with a wooden stick
3. Use in the pond: for every 1000 liters, add 1 crushed tablet to the pond water
4. Repeat control every 4 weeks

Mosquito larvae in the rain barrel can be avoided in different ways

With the help of a fizzy effect, you can check whether the remedy is doing its job. In a water barrel, all mosquito larvae are destroyed within 2 to 3 hours. The duration of the effect in the pond depends on the volume of water. Since Bacillus thuringiensis israelensis is a very specific remedy, it does not affect other aquatic life such as fish, frogs or toads. The disadvantage is that the bacteria not only kill black mosquito larvae, but also have to believe in harmless white and red mosquito larvae.

Kill mosquito larvae inside

In living spaces, the control of mosquito larvae mainly focuses on preventive measures. Avoid potential breeding grounds. How to do it right:

• do not leave open liquids standing around
• Dump the dog and cat's drinking bowl every day, clean it and refill it fresh
• Remove water from saucers no later than 10 minutes after watering
• Do not put a filled, open water glass on the bedside table
• Always put away wet bath and kitchen sponges

Do not underestimate the damp sink in the bathroom and kitchen as a potential nesting place for mosquito larvae. If you pour a good gush of boiling hot water into the opening every day, mosquito females will thwart your plans. In addition, we recommend regularly scrubbing all drainage openings in the house thoroughly with a brush and vinegar water.

frequently asked Questions

How long do mosquito larvae take to hatch?

Mosquito larvae go through four stages of development up to pupation. Depending on the species and habitat, this period extends from a few weeks to several months. Mosquitoes therefore spend most of their lives as larvae. The pupal stage is only a few days, with hatching even with red mosquito larvae within a few seconds and with black mosquito larvae within a few minutes.

What helps against mosquito larvae in the pool?

Buy a pool vacuum with a telescopic rod. With this device you simply suck off mosquito larvae from the surface of the water. If this method is too time-consuming for you, install a sand filter system to remove mosquito larvae from the pool. It is cheaper to use detergent that you drip onto the surface of the water. This breaks the surface tension and the mosquito larvae sink. This procedure has the advantage that you primarily kill black mosquito larvae from mosquitoes. Red mosquito larvae, on the other hand, breathe through the skin and are spared.

I want to breed mosquito larvae as live fish food. What do mosquito larvae actually eat?

Mosquito larvae have very different ways of life. Most species live in the sweet or salt pass and adjust their diet accordingly. The menu mostly contains degradation substances from the water and tiny algae. Some species of mosquito larvae settle on aquatic plants to nibble on the floating leaves. There are also predatory species that feed on other insect larvae. White mosquito larvae, for example, like to hunt water fleas. If you breed mosquito larvae yourself, the nutrition plan depends on the respective species.

Red mosquito larvae are suitable for which fish?

Whether you feed red mosquito larvae in the pond or aquarium depends on the composition of the fish. Familiarize yourself in advance with the profile of every species of ornamental fish that cavort in the water. Many freshwater and saltwater fish like to eat red mosquito larvae and can tolerate this diet well. These include sticklebacks, carp and goldfish. For some fish, on the other hand, consumption causes digestive problems, such as the exotic cichlids.
