How do I recognize diseases that mosquitoes cause

Mosquitoes (plage): How you can now optimally protect yourself

SOS: The best home remedies for mosquito bites

Scratching is not a good idea! By doing this, you're promoting bacterial inflammation and making it much worse. When you scratch, you spread the insect's saliva and the itching becomes worse.

Cold packs: Cool the affected area as soon as possible. The cold ensures that the bite does not catch fire. A cold gel compress or ice cubes also provide relief from itching. It is best to wrap cooling agents in a tea towel before putting them on.

Vinegar water: Vinegar combats the itching. Mix 5 tablespoons of vinegar with 200 ml of cold tap water. Drizzle the vinegar water onto a tea towel or cotton pad and place it on top.

Quark: Cool quark helps reduce swelling and has an anti-inflammatory effect. Apply a tablespoon and spread it around the bite.

Alcohol: A compress with high percentage alcohol cools the wound. The evaporation cold creates cold and alcohol reduces the irritation.

Honey: This has an anti-inflammatory effect. Just a few drops not only relieve the itching, but also the swelling.

Salt water: A teaspoon of salt can also help relieve itching. Dissolve it in cold water and brush the mixture onto the affected area.

Aloe Vera: The plant reduces the itching. Squeeze the juice of a leaf and drizzle it on the sting.

Lavender oil:This has a disinfecting effect. Give it straight to the stitch.

Hot spoon: The heat destroys the mosquito protein that causes the itch. A heated coin, hot candle wax, or warm water work in the same way. The temperature should be 45 to a maximum of 50 degrees.

Daisy:Squeeze out the sap from the stem, leaves and flower. You can then use it to treat the affected area.

White cabbage: The cabbage prevents inflammation. Dab the juice of the cabbage on the sting.

Onion: The sulfur has an antibacterial and disinfectant effect, relieves itching and can reduce swelling. Cut an onion in half and place the cut side directly on the affected area.

Tea tree oil: This has a disinfecting and pain relieving effect. Drip it directly onto the bite. A bowl of tea tree oil in front of your window can also keep insects away. You avoid the smell.

Horseradish: The vegetables stimulate the blood circulation. As a result, the mosquito protein is broken down more quickly. Rub the horseradish very finely and put an envelope on the affected area.

Ribwort plantain:Rub 1-2 sheets of paper in your hands, then place them on top. Fix the leaves with a cloth and leave the herb on the sting for 2 hours.

Toothpaste:This should curb the itching. Simply apply directly.

Important: If the puncture site is very swollen and does not stop itching, you should consult a doctor. The stings can become infected. The result is a festering and extremely painful wound. Allergy sufferers in particular should be careful because insect bites can trigger violent reactions, including anaphylactic shock.

Mosquitoes 2018


What can we expect from the mosquitoes in 2018? This is what the official mosquito calendar says:

  • First appearance: after the frost has subsided
  • High season 2018: from June 1st to September 30th, 2018
  • Post-season: until the first frost
  • Popular time: in the evening hours
  • Popular climate: warm and humid
  • Popular areas: near standing water, pools, puddles, in the garden by setting up
  • from a paddling pool or a water tank

However, the experience of the last few years has shown that the stinging pests don't really stick to the mosquito calendar. They love warm weather and the sudden onset of spring encourages them to appear early. The rule is: A hot April always brings a mosquito plague. It can therefore be assumed that the insects will be buzzing around before and long after the end of September.

Why do mosquitoes bite?

The assumption that mosquitoes generally bite is wrong. Only the female mosquitoes like to bite. Male mosquitoes feed on flower nectar and do not need blood. Female mosquitoes depend on the proteins and other nutrients in human blood to ensure the production and growth of their eggs. The female leaves saliva in the victim's wound. The saliva contains an anticoagulant. This allows the mosquito to soak up the blood unnoticed.

Mosquito bites: why always me?

Some people attract mosquitoes more than others. Various factors play a role here.

Fragrances: The special composition of the body's own odor (which depends on the genes) can determine whether the mosquito stings or not. However, the underlying mechanism is so far unclear.

Blood type: Japanese scientists have found that people with blood type 0 are the most likely to be stung. Mosquitoes recognize the blood group through a certain chemical signal on the skin.

Carbon dioxide: The animals can smell the gas that each of us exhales from a great distance. For this reason, pregnant women are particularly often attacked because they breathe for their baby.

other smells:Mosquitoes react to lactic acid, ammonia and fatty acids. People emit these smells especially after exercising, when they are sweaty and heated up.

Colour: The stinging insects have a weakness for dark surfaces. So far, however, we don't know why.

How often can mosquitoes bite?

The animals can sting indefinitely. Females repeat the process of sucking blood until they are full. They then rest for 3 weeks and then lay their eggs. When the process is complete, repeat the entire process.

What does a mosquito bite look like?

If you have been attacked by a mosquito, a red swelling will appear on the skin. This can be found anywhere on the body. Arms and legs are not clothed, especially in summer, and are therefore a popular destination.

Why do mosquito bites itch?

The reddening of the skin is an allergic reaction to the mosquito's saliva. The human body releases histamine as a defense measure. This in turn causes the redness, inflammation and itching at the sting point. The more mosquito saliva lands in the body, the stronger the itching.

What diseases are transmitted by mosquitoes?

The little animals are not as harmless as they look. When bloodsucking, certain types of annoying bloodsuckers transmit dangerous diseases. You can see the five most common ones here.

Malaria: The Anopheles mosquito is responsible in tropical regions. A certain minimum temperature over a longer period of time is required for the transfer. In Germany around 700 cases of returning travelers are reported each year. The disease is fatal in 1 to 3% of patients.

Yellow fever: Yellow fever is a viral disease that is passed on by Aedes mosquitoes. Asia, Australia, Europe and Oceania are currently considered to be yellow fever free. Before traveling to tropical Africa or South America, travelers should inform themselves in advance whether a vaccination is required.

Dengue fever: The virus is also transmitted by the Aedes mosquito species. The dangerous virus is particularly widespread in the tropical and subtropical regions of Central and South America, South and Southeast Asia and Africa. Due to increased travel activities in the affected countries, the number of cases of dengue fever in Germany has risen sharply in recent years. More than 600 cases were reported in 2012. The most common country of infection was Thailand.

Zika virus: The Zika virus is also transmitted by mosquitoes of the genus Aedes, more precisely the "Asian tiger mosquito". Most cases of the infectious disease are currently occurring in Latin American countries. The disease itself is usually harmless and the symptoms are similar to ordinary flu. However, pregnant women and women planning to become pregnant should avoid traveling to risk areas as there is no vaccination option and the virus can cause malformations in babies. Otherwise there is so far no immediate danger for Germany and Europe.

West Nile fever: West Nile fever is caused by viruses and is mostly transmitted by Culex mosquitoes. Above all, wild birds carry the virus and have meanwhile spread it widely - also in Europe. An infection leads to mild flu-like symptoms in only one in five cases, in the remaining cases it is without symptoms. However, old and immunocompromised people can develop severe and sometimes life-threatening courses. Inflammation of the meninges or myocardium can occur. There is no vaccination against West Nile fever.

Mosquito repellent

There is no 100% protection against bloodsuckers. A few commercial remedies can, however, contain the plague somewhat.

Mosquito plug:Mosquito plugs spread insecticides in the room, which put the stinging animals out of action. This works quite effectively, but you shouldn't forget to ventilate! Such plugs are not entirely harmless to health in the long run.

Mosquito screen and mosquito net:They enable rooms to be ventilated without letting in uninvited guests.

Mosquito spray: Anti-mosquito sprays mainly work with odors. The spray covers the human odor and spreads a scent that is unpleasant for mosquitoes. In most cases, active ingredients such as Icardin and DEET are used. The exact composition can vary. Not every spray works equally well for everyone. This is due to the fact that every person has their own body odor, which in turn harmonizes better with certain substances than with others.

Impregnated clothing:Light, long clothes and tightly woven fabric protect against mosquitoes so that the animals cannot get through. Ideally, you should also impregnate your clothing with a clothing spray provided for this purpose.

How effective are mosquito repellants (sprays)?

According to Stiftung Warentest, only a few of the large number of mosquito repellants offered offer really good protection against the stinging pests. In the examination of 21 products, only two achieved a "very good" mosquito protection.

However, the testers do not consider essential oils such as lavender, citronella or geraniol to be absolutely recommendable. They evaporated very quickly, so they have to be freshly applied very regularly. In addition, they can trigger allergic reactions of the eyes, skin and mucous membranes in sensitive people.

Vaccinations as prophylaxis for trips abroad

In addition to helping protective and home remedies, there are a number of travel vaccinations against diseases that can be caused by mosquitoes. You should definitely do this before starting your journey in order to eliminate the risk of life-threatening infectious diseases! The statutory health insurance companies only partially cover the costs for vaccinations against yellow fever and the like, or not at all. With DFV outpatient protection, however, you are protected for every trip. We cover the cost of vaccinations as prophylaxis for trips abroad as well as for extended preventive services and provide financial support for serious illnesses! Comprehensive protection for long-lasting health!
