Have you ever wondered why you get bitten while others around you don't? It's true. Mosquitoes do exhibit blood-sucking preferences, say the experts. One in 10 people are highly attractive to mosquitoes.

• People with high concentrations of steroids or cholesterol on their skin surface.
• People who produce excess amounts of certain acids, such as uric acid.
• Larger people and pregnant women who tend to give off more carbon dioxide.
• Movement and heat also attract mosquitoes.

• DEET continues to be the chemical of choice. In repeated studies, it's been proven the most effective chemical repellent on the market.
• Picaridin has proven to be as effective as DEET but is more pleasant to use. Picaridin is safe for children older than 2 months.
• Metofluthrin. Available as a paper strip for outdoor areas and as a personal repellent clipped onto a belt or clothing. It is not applied to the skin. 

• Soybean oil-based repellent provide short-lived protection.
• Lemon eucalyptus is safe for children older than 3 years and offers protection similar to low concentrations of DEET.
• Mosquito traps.
• Insect shield repellent apparel for outdoor enthusiasts; clothing infused with the chemical insecticide Permethrin.
