Mosquitoes are more than just a nuisance. They carry diseases like West Nile virus, Zika, and dengue fever. Choosing the right repellent protects you and your family during outdoor activities. Here is a guide to the mosquitoes best repellent options based on scientific testing and effectiveness ratings.
The most effective mosquito repellents contain DEET, picaridin, or oil of lemon eucalyptus. The Centers for Disease Control and Prevention (CDC) recommends these active ingredients for protection against mosquitoes. The best repellent for you depends on the level of mosquito activity, the duration of outdoor exposure, and your personal preferences for the product format.
DEET-Based Repellents
DEET is the most widely studied and effective mosquito repellent active ingredient. It has been used for over 60 years and is recommended by the CDC and World Health Organization. DEET works by blocking the mosquito ability to detect carbon dioxide and body odors that attract them to humans. Products with 20 to 30 percent DEET provide 4 to 8 hours of protection against mosquitoes.
DEET concentrations from 10 to 30 percent are available in sprays, lotions, and wipes. Higher concentrations provide longer protection, not stronger protection. A 30 percent DEET product protects for about 6 to 8 hours. A 10 percent DEET product protects for about 2 to 3 hours. Choose the lowest concentration that provides the protection time you need for your outdoor activity.
DEET is safe for use on adults and children over 2 months old when used according to the label directions. Apply DEET only to exposed skin and clothing. Do not apply to eyes, mouth, or irritated skin. Wash treated skin with soap and water after returning indoors. DEET can damage synthetic fabrics, plastics, and watch crystals, so take care when applying near these materials.
Picaridin Repellents
Picaridin is a synthetic repellent that is nearly as effective as DEET but with a more pleasant feel and odor. Picaridin was developed in the 1980s and has been available in the United States since 2005. It is recommended by the CDC as an effective alternative to DEET. Products with 20 percent picaridin provide 6 to 8 hours of protection against mosquitoes.
Picaridin has several advantages over DEET. It is odorless and does not have the strong chemical smell associated with DEET products. It feels lighter on the skin and does not feel greasy or sticky. Picaridin does not damage synthetic fabrics, plastics, or finished surfaces. It is also effective against ticks, making it a good choice for areas with both mosquitoes and tick-borne diseases.
Picaridin is available in spray and lotion formulations at most outdoor and drug stores. Products containing 20 percent picaridin provide the best balance of effectiveness and feel. Lower concentrations are available but provide shorter protection times. Picaridin is approved for use on children over 2 months old and is well tolerated by sensitive skin types.
| Ingredient | Protection time | Best for | Notes |
| DEET 20-30% | 4 to 8 hours | Heavy mosquito areas | Gold standard, can damage synthetics |
| Picaridin 20% | 6 to 8 hours | All-purpose use | Odorless, no fabric damage |
| Oil of lemon eucalyptus | 4 to 6 hours | Natural option | Not for children under 3 |
| IR3535 20% | 4 to 6 hours | Sensitive skin | Good for children |
Natural Repellent Options
Oil of lemon eucalyptus (OLE) is the most effective natural mosquito repellent. The CDC recommends OLE as an effective alternative to DEET. Products containing 30 percent OLE provide 4 to 6 hours of protection. OLE is derived from the leaves of the lemon eucalyptus tree and has a pleasant citrus scent that most people find appealing for outdoor use.
Other natural repellents like citronella, peppermint oil, and lavender oil provide limited protection. These natural oils typically provide 30 minutes to 2 hours of protection and require frequent reapplication. They are less effective than DEET, picaridin, or OLE for extended outdoor activities in areas with high mosquito activity during prime mosquito hours.
Natural repellents are a good choice for short outdoor activities or as a supplement to other protection methods. They are also useful for people who prefer to avoid synthetic chemicals on their skin. However, for extended outdoor time in areas with mosquitoes carrying diseases, EPA-registered repellents with DEET or picaridin provide more reliable protection.
Other Mosquito Protection Methods
In addition to repellents, physical barriers provide excellent protection against mosquitoes. Wear long sleeves, long pants, and socks when outdoors during peak mosquito hours at dawn and dusk. Treat clothing with permethrin, an insecticide that repels and kills mosquitoes on contact. Permethrin-treated clothing remains effective through multiple washes and provides protection without applying repellent to your skin.
Mosquito nets provide protection while sleeping. Use bed nets treated with insecticide in areas with mosquito-borne diseases. Fans create airflow that makes it difficult for mosquitoes to fly and land on you. Mosquito traps and yard treatments reduce the mosquito population around your home but do not provide complete protection and should be used with personal repellents.
Eliminate standing water around your home to reduce mosquito breeding sites. Mosquitoes lay eggs in standing water. Empty and clean bird baths, pet water bowls, plant saucers, and gutters weekly. Treat standing water that cannot be drained with larvicide products to prevent mosquito larvae from developing into biting adults in your yard.
A medical entomologist with 25 years of experience explained: “The most common mistake people make with mosquito repellents is applying too little or not reapplying frequently enough. A thin, even coating on all exposed skin is sufficient. Reapply according to the label directions, especially after swimming, sweating, or toweling off. No repellent provides all-day protection from a single application in most conditions.”
