Today's useless fact - Does taking vitamin B prevent mosquito bites?

In a word, no. Dr. Jonathan Day, an expert on mosquitoes, doesn't think so: "We've tested many home remedies like garlic, bananas and vitamin B," says Dr. Day. "While they may offer other health benefits, repelling mosquitoes and other biting insects is certainly not one of them." Instead, Dr. Day recommends any repellent featuring the chemical compound DEET, which has been on the market for over 40 years. So stick to the spray and mosquito repellents. Mosquito repellents generally contain one of the following active ingredients: DEET, Catnip oil extract - Nepetalactone, Citronella or eucalyptus oil extract. Often the best "repellant" is a fan or gentle breeze as mosquitoes do not like moving air. Check out the links in our Mosquito category and DEET category for more.
