I suffer from an extreme reaction from mosquito bites. The bites become blistered and I've had to take antibiotics several times. Is there something I can do that will, at least, minimise the bites? ROBERT MUSEKA, by e-mail Although mosquito bites aren't always life-threatening, they can be incredibly frustrating.
It’s not understood why some people get bitten and others don’t. What we do know is that mosquitoes are attracted by the carbon dioxide we exhale and the heat of our skin, as well as the scent of perfume and body creams. When a mosquito bites, it injects you with saliva to prevent your blood clotting as it sucks it out. Some people are allergic to these secretions; this causes the swelling and blistering. Antihistamines will help reduce the itching, but as you are clearly severely allergic to the bites, it’s important you avoid getting bitten in the first place.
Contrary to popular belief, there is nothing you can take by mouth – such as vitamin B – to deter insects from biting you.
Insect repellents applied to the skin work well – if used correctly. This means buying a suitable type and applying it regularly to all areas of the skin that are exposed. Look for products containing Deet, as this is the gold standard in repellents. Deet works by affecting the receptors of the mosquito, so they can’t detect you. There are a number of brands on the market – generally speaking the higher the concentration, the longer the product will work. A strength of 50 per cent is recommended for adults and 30 per cent for children. If you find Deet too toxic-smelling, there are eucalyptus and citronella-based products that are also effective and suitable for young children.
However, my preferred alternative is an ingredient containing picaridin, found in Autan products. Whatever product you use, apply it to all exposed skin every four hours from the start of the day. Other ways to protect yourself are by wearing unscented body lotion and white or pale clothing. Keep covered up, particularly around your wrists, neck and ankles. Use a mosquito net at night. If you are meticulous and follow the steps I’ve suggested, you will keep your suffering to a minimum.
