What makes bug bites so itchy?

Answer 1

When the mosquito stabs her needle-like mouthparts through the skin of her victim, she injects her saliva -- teeming with digestive enzymes and anticoagulants. The first time a person is bitten, there is no reaction. With subsequent bites, the person becomes sensitized to the foreign proteins, and small, itchy, red bumps appear about 24 hours later. This is the most common reaction in young children. After many more bites, a pale, swollen hive, or wheal, begins to appear within minutes after a bite -- followed by the red bump 24 hours later. This is the most common reaction in older children and adolescents.

With repeated mosquito bites, some people begin to become insensitive again, much as if they had allergy shots. Some older children and adults get no reaction to mosquito bites (unless they go for a long time without being bitten -- then the process can start again). Other people become increasingly allergic with repeated stings. They can develop blistering, bruised, large inflammatory reactions. For these people, avoiding being bitten is a particularly good idea.

Answer 2

bugs and any other insects causes itchiness when they bite because they releases chemicals from their body into the body of their pray. Actually these chemicals such as in bugs, they use it to kill preys that are the same or smaller size than them. Like in spiders of the forest that as big as mouse that bites birds, the birds easily dies because of that chemical, after then endevour the bird. In our case the poison is not enough to kill us so it just react to our body as allergies, or some swelling and itchiness, others makes us sick such waps' bite. Some waps bite can be deadly when you a bunch of wasp bitten you. Another way it can be deadly is that when a certan bug bitten you once... then the chemical remain in your body...it will never hurt you at first.. but after a few days then you are again bitten by the same kind of bug the chemical will then react and killed you instantly. more poisonous than snake bites.

Bugs have an anti-clotting enzyme in their saliva so that when they are sucking your blood, it doesn't clot. Some people are more sensitive to this enzyme than others and have an allergic reaction to it. For most people, it is a small, itchy welt; for others, it can become a huge welt that they need medicine to alleviate.
