Each year, many children and adults suffer stinging insects such as wasps, mosquitoes etc .. The most unfortunate biting insects who suffer pain and discomfort that usually lasts a few hours. Symptoms may include redness, swelling and itching at the bite.
However, some people are allergic to insect bites. This means that their immune systems overreact to the product injected by an insect. After the first bite, the allergic person's body produces a substance called immunoglobulin E antibody (IgE), which reacts with the toxic insect. The person does not usually experience a severe allergic reaction that first bite but if you have another same insect bite or a similar species, the insect venom interacts with the IgE antibody produced in response to the first bite. This triggers the release of histamine and other chemicals that cause allergic symptoms.
Symptoms of severe reactions
Among the few people with severe venom allergy, stings may be life-threatening. Severe allergic reactions to insect stings can affect many organs and develop rapidly. This reaction is called anaphylaxis. Symptoms of anaphylaxis may include hives over large areas of the body, swelling in the throat or tongue, difficulty breathing, dizziness, cramps (abdominal discomfort), nausea or diarrhea. In extreme cases, a rapid fall in blood pressure may result in shock and loss of consciousness. Anaphylaxis should receive urgent medical treatment and can be fatal. If you or someone else is experiencing any of these symptoms after an insect sting, obtain emergency medical treatment immediately.
Identification of biting insects
To avoid insect bites, it is important to learn to recognize them and know where they live. Most sting reactions are caused by five types of insects: yellow jackets, honeybees, wasps, hornets and fire ants.
The yellow jackets have black and yellow markings, and are in different climates. Their nests, which are made of papier-mache-like material are usually located underground, but can sometimes be found on the walls of buildings, cracks or woodpiles.
Honeybees have a rounded and "hairy" body with dark brown colors and yellow markings. When chopping, the honeybee usually leaves its barbed stinger in its victim; therefore bee dies. Honey bees are not aggressive and only sting when provoked. However, Africanized honeybees, or so-called "killer bees" found in parts of South and Central America are more aggressive and can bite into groups. Domesticated honeybees live in man-made hives, while honey bees live in colonies or "panels" in hollow trees or cavities of buildings. African bees can nest in holes in structures of houses, including fence posts, in old or holes in the ground or other partially protected sites wheels.
The wasps have slender, elongated bodies of black, brown or red with yellow markings. Nests are also made of paper-like material into a circular cells honeycomb opens downward. The nests are often placed under eaves, behind shutters or in shrubs or woodpiles.
Hornets are black or brown with white markings, orange or yellow and usually are larger than the yellow jacket. Their nests are gray or brown, shaped American football and hollow material similar to paper yellow jacket nests. Hornets' nests are usually in height on branches of trees, bushes, gables or in tree hollows.
Fire ants are biting insects brownstone related to bees and wasps. His protruding mounds, common in warmer climates, can measure up to 90 cm in diameter and 45.7 cm in height, and can contain up to 250,000 ants. Fire ants may attack without warning: after firmly grasping the skin of its victim with its jaws, the fire ant arches its back and inserts its rear stinger. Then turns around and bites usually about eight times in a circle, the fire ant venom has a high concentration of toxins, which cause burning pain.
Get away from the "territory" of the nests of stinging insects. These insects are "social" and bite if they feel threatened their home, so it is important to destroy hives and nests around your home. Since this can be a dangerous activity, you should be hired a trained exterminator.
If you find flying stinging insects, remain calm and silent, moving slowly. Many stinging insects look for nectar, so you should avoid looking and smelling like a flower, avoid brightly colored clothing and perfume when outdoors. Because the smell of food attracts insects, be careful when cooking, eating or drinking sweet drinks like soda or juice outdoors. Keep covered until serving food. Wear closed shoes and avoid going barefoot. Also, avoid loose clothing that can trap insects between material and skin.
Insect bites treatment
If stung by a honey bee that has left its stinger (with venom sac attached) in the skin, remove the stinger within 30 seconds to avoid receiving more venom. Rapidly with your fingernail scraping the stinger and the bag is removed. Avoid squeezing the sac, this injects more venom through the stinger into the skin. Hornets, wasps and yellow jackets do not usually leave their stingers.
Try to stay calm, and these insects scare them away from the skin promptly with deliberate movements to avoid more stings. Then, leave the area immediately silent.
If biting red ants, and keep them away carefully to avoid more bites and leave the area. The fire ant stings cause a reaction in almost all its victims. Itchy hives located where the insect was then commonly happens within 30 to 60 minutes is formed. Within four hours, a small blister which saw each bite is formed; a wound with pus is formed in eight to 24 hours. This then breaks and wound heals within 48 to 72 hours. Bites should be monitored so that no secondary bacterial infection. Up to 50% of patients develop large local reactions at the point where stinging ants; inflammation can last for several days and may be accompanied by itching, redness and pain.
If you take the following measures can help address local reactions to insect stings:
- Elevate the affected arm or leg and apply ice or a cold compress to reduce swelling and pain.
- Gently clean blisters with soap to prevent secondary infections and water; not break blisters.
- Use topical steroid ointments or oral antihistamines to relieve itching.
Consult your doctor if inflammation or increases appears to have infection. If you have severe allergies to insects and has had previous reactions, try to avoid being alone outdoors if there are insects in case you need quick emergency treatment.
