Other vectors include ticks, fleas and sandflies. Many of the creatures classified as vectors are bloodsuckers. Vectors often carry infections through blood. Mosquitoes are vectors (living things that carry diseases between animals and humans). Mosquitoes spread disease through their bites. Most people have a mosquito bite allergy. Histamine is what causes your mosquito bites to itch and swell. Your immune system then sends the chemical histamine to the area where the mosquito bit you to remove the allergen from your body. When a mosquito secretes saliva into your bloodstream, your body registers the saliva as an allergen. When a mosquito bites you, it uses this mouthpart to pierce your skin, suck your blood and secrete saliva into your bloodstream. Mosquitos have a long mouthpart (proboscis) that extends far beyond their heads. The females need the protein in blood to develop eggs. Though male mosquitoes only eat flower nectar, female mosquitoes eat both flower nectar and blood. Mosquitoes bite and suck blood for reproduction. The eggs are usually in marshes, ponds, lakes, children’s pools, the inside of tires, birdbaths and other containers with shallow water. They lay their eggs in shallow, stagnant water.

However, mosquitoes are dangerous because they spread diseases that can be fatal. They cause mild annoyance and irritation for a short period. Often, mosquito bites don’t cause any lasting harm. Three different types of mosquitoes exist in various parts of the world: Aedes, Culex and Anopheles. Only female mosquitoes feed off of blood. They have six legs and long mouthparts - used to feed on blood and nectar.
