Larvae live in stagnant water, such as ponds and rain barrels.
After the winter (last year) fertilized females lay eggs on the water. After 7-10 days come larvae. After 1 - 2 weeks the larvae pupate. After another 1-2 weeks they mature. Later in the year, in the air, while flying, the young females and males are mating. Only the fertilized females overwinter. A mosquito weighs 2 milligrams.
Mosquitoes life of nectar. The females suck human blood during the production of eggs. The female lives on average two to three weeks. For three days she lays eggs. Therefore she must engorge once her stomach with blood. Therefore, a mosquito remains coming back until she has enough blood. The itchy bumps feel like hives.
Biting mosquitoes can cause serious damage by diseases that they can spread, such as the infamous West Nile disease or malaria (in the tropics).

Mosquitoes are attracted by the smell of man, not by light. Mainly lactic acid, ammonia, carbon dioxide and acid are delicious smells for mosquitoes. Everyone has those substances naturally on his skin. Eating brewer’s yeast would make our scent for mosquitoes unattractive, and is not noticeable to humans.

You can confuse their smell organ or block it with fragrances such as citronella or DEET (: is in mosquito plugs and sticks). Lavender oil could help. Citronella works but short (about 15 minutes). Mosquitoes are after a couple of hours used to the lemon air. From that moment they can sting again.

The Centers for Disease Control and Prevention confirm that lemon -eucalyptus oil is as effective as DEET to repel mosquitoes. The lemon eucalyptus (Eucalyptus citriodora or Corymbia citriodora) is a 50 meter tall tree in northeastern Australia.
Lemon eucalyptus oil is extracted from the leaves and twigs. P-menthane-3,8-diol (PMD) is the synthetic version with pesticidal properties.

Stabbing mosquitoes survive winters even at -30 degrees Celsius, in a kind of hibernation, so eg in Finland and Siberia.

They emit excess water, making their body fluid a thicker, more frost-resistant paste.

Mammals that whip with their tails can cause more than 50% of approaching mosquitoes to turn around due to the air flow.

Mosquito lotion
Mix 1/2 liter of alcohol 96% with 100 grams of cloves. Let this soak a few days and shake the bottle regularly. Remove the cloves and add 100 ml of oil (almond, sesame,...) to make a lotion.

Draft or a fan help. Mosquitoes cannot stand the strong airflow and thus literally are blown away.

Rub with a sorrel leaf on the mosquito bite. Or put a paste of baking soda with a little water.

An excellent remedy against mosquitoes? Spiders. They are specialized mosquitoes (and flies) catchers. So maybe less vacuuming and sweeping.

Cover your bed with a mosquito net.
An excellent remedy for itching? Working. Try it. If you 're busy you do not feel any itching. If you sit around doing nothing at the other hand...

Why did Noah not swatted those two mosquitoes?
