'Tho small in size, mosquitoes have been around for millions of years. They use chemical, visual and heat sensors to locate their prey. Chemical sensors detect carbon dioxide and lactic acid from 100 feet away. and chemicals in sweat can also trigger their sensors. Their visual sensors aren't very keen, but they can see you moving if you're wearing clothes that contrast with the background. They use their heat sensors to detect warm-blooded mammals and birds in their vicinity.
Mosquitoes go through 4 stages in their life cycle: egg, larva, pupa and adult. The first 3 stages are aquatic and last 5-14 days. All mosquitoes must have water in which to complete their life cycle.
Visible, irritating bites are due to the immune response from the binding of antibodies to antigens in the mosquito's saliva. Anti-itch medicines are usually orally or topically applied. Many home remedies/recipes exist including vinegar and toothpaste. Also rubbing clear nail polish or deodorant on the bite will stop the itching most of the time.
