Why mosquitoes bite

But most of this research uses only one mosquito species. Switch to another species and the results are likely to be different. There are up to chemical compounds on human skin that could play a role in attracting and perhaps repulsing mosquitoes.

This smelly mix, produced by bacteria living on our skin and exuded in sweat, varies from person to person and is likely to explain why there is substantial variation in how many mozzies we attract. Genetics probably plays the biggest role in this, but a little of it may be down to diet or physiology. One of the best studied substances contained in sweat is lactic acid. Probably the most famous study about their biting habits demonstrated that the mosquitoes that spread malaria Anopheles gambiae are attracted to Limburger cheese.

The bacteria that gives this cheese its distinctive aroma is closely related to germs living between our toes. That explains why these mosquitoes are attracted to smelly feet. The immune response is something that the body learns after being exposed to a foreign substance.

Some people may never react to a bite. For many, the reaction remains consistent, and mosquito bites continue to be an annoyance. Mosquitoes bite humans to drink their blood. Only female mosquitoes bite people. It locates the blood vessel and draws blood up through its mouth. As it does this, it injects saliva that contains an anticoagulant.

Mosquito bites itch due to inflammation. Rather than relieving the itching, scratching an already inflamed area increases inflammation. This makes the area even itchier. Scratching may also increase the risk of infection if it breaks the skin. If the area becomes infected, it will be much itchier and will take longer to heal. Antihistamines are an over-the-counter medication that help to reduce inflammation and itching.

They are an effective way to treat mosquito bites. A study found that locally administered heat brought fast relief to mosquito bite symptoms. Honey is antibacterial and may help wounds heal.

A study found that natural honey can reduce inflammation and prevent infection. For this reason, natural honey may help reduce the symptoms of a mosquito bite when applied to the affected area. It is essential to wash it off before going outside, as it can attract mosquitoes and other insects. As these creams are steroid based, people should use them sparingly and should not apply them to open wounds.

They may also cause the skin to thin with repeated use. One species of aloe, Aloe littoralis , has been shown to reduce inflammation and encourage wound healing in animal studies.

A study on animals found basil oil helped to relieve inflammation in arthritis. The anti-inflammatory properties of basil oil suggest it could help to relieve mosquito bite inflammation. Mosquito bites can become infected, which may mean they take longer to heal.

Anti-itch cream for a mosquito bite. Treat clothing and gear with permethrin. Links with this icon indicate that you are leaving the CDC website.
