The best remedy for itchy mosquito bites is to prevent them in the first place. Use these tips to help stay bite-free this spring and summer: 1. Stay indoors at dusk when mosquitoes are out and about. 2. Wear loose-fitting, long-sleeved tops, and tuck long pants into your socks. 3. Stay away from black and white fabrics, which seem to drive the little bugs wild. 4. Try mixtures of essential oils, such as pennyroyal oil and eucalyptus. These are moderately effective if you're not dealing with really thick swarms of mosquitoes. 5. In places like Alaska or Minnesota, where mosquitoes can be overwhelming, use insect repellants containing geraniol, a plant-derived compound, or neem oil, from the Indian tree Azadirachta indica.
