Mosquitoes are alerted to your presence by the production of carbon dioxide, which indicates the proximity of a biteable mammal.
At best, mosquito bites prove to be an annoyance, as the bite creates an allergic reaction that leads to swelling, itching and raised areas on the skin. The irritation caused in the aftermath of a mosquito bite is due to a response by the immune system, as the body’s antibodies bind to the antigens in the mosquito’s saliva.
The itchiness caused by a bite can last for up to 72 hours. While scratching creates temporary relief, it also exacerbates the problem, leaving the area sensitive and inflamed.
At worst, mosquitoes run the risk of transmitting malaria, yellow fever and other infections, which are passed from insect to human through the process of injecting the proboscis into the skin, and the drawing of blood.
There are simple steps to take to prevent bites from mosquitoes, ensuring a safe, irritation-free and relaxed stay abroad:
Take Thiamin
While not scientifically proven, the intake of Thiamin is thought to create an odour undetectable by humans, which repels biting insects. Vitamin B is a highly-scented substance that can ‘flavour’ the blood. The odour, while subtle, is thought to mask the common scents of perspiration that the skin gives off in temperate climates, making it less likely that a mosquito will be alerted to the presence of a potential target. It is recommended that Thiamin is taken up to two weeks in advance of travel to provide the best possible protection.
Consume Garlic to Ward off Interest
Like Thiamin, Garlic is thought to alter the scent of skin and the blood, making it more difficult for a mosquito to identify its potential victim. Again, the earlier garlic is taken before travel, the more likely it is that the scent will permeate the skin, making it unappetising for predators.
Use Citronella Oil
A highly-scented essential oil, Citronella is similar to lemon, with a sharp acidic edge. The perfume is unappealing for mosquitoes, and also works to mask the scents given off naturally by the human body. By dousing clothes and skin in Citronella, it is possible to deter insects and make it much less likely that a bite will occur. Citronella is a pleasant, citrus scent that can be worn in place of a regular perfume, while abroad.
Cover up From Head to Toe
Mosquitoes cannot bite through cloth. All areas covered by clothing will be impermeable by the insect. The most common places for bites to occur are on legs and arms – keep them covered to ensure maximum protection.
Use products High in DEET
DEET is a clinically proven mosquito repellent. In more high-risk areas, it is recommended that alternative deterrents are used as a back-up only, as there is no substitute for this scientifically recommended spray.
When sleeping in tropical areas, always use a mosquito net and ensure that doors and windows are properly sealed.
Reduce Irritation
If a bite takes place, there are a number of available treatments. Antihistamines, corticosteroids, baking soda, alcohol, vinegar or toothpaste are all thought to reduce irritation and make the inflammation calm down. Ammonia is also a clinically-proven treatment to reduce swelling and remove irritation.
