Picaridin

• You can use Picaridin as a repellent for mosquitoes, biting flies, ticks and chiggers, according to the EPA. Originally used in Europe and Australia (under the name Icaridin), Picaridin became available to the United States in 2005. Unlike DEET, Picaridin doesn't smell and may not aggravate your skin. Though rare, DEET can cause seizures in children, confusion and slurred speech, said the Illinois Department of Public Health. Picaridin also won't damage plastics, watch crystals and some forms of fabrics, such as rayon.
  
  

Oil of Lemon Eucalyptus

• Considered a natural product, oil of lemon eucalyptus offers as much protection as the lower DEET concentrations (10 percent and less). DEET comes in concentrations of 4 to 100 percent. Introduced in the 1940s, oil of lemon eucalyptus helps to kill mites and insects. You can find oil of lemon eucalyptus in many insect repellent lotions and sprays. Unlike DEET, oil of lemon eucalyptus doesn't have a greasy feel after application, according to the University of Nebraska-Lincoln.
  
  

Oil of Citronella

• Oil of citronella is another natural product. Citronella has a distinctive odor, which helps to cover the carbon dioxide expressed by your body, according to the EPA. Oil of citronella is commonly used in candle repellents. Application methods include rub-on products, gels, towelettes, lotions and sprays. Oil of citronella helps to repel common pests such as mosquitoes, ticks, fleas and flies.
