Recommendations for US Travelers
Protection from Mosquito Bites
- When outdoors or in a building that is not well screened, use insect repellent on uncovered skin. Always apply sunscreen before applying insect repellent.
- Look for a repellent that contains one of the following active ingredients: DEET, picaridin (KBR 3023), oil of lemon eucalyptus/PMD, or IR3535. Always follow the instructions on the label when you use the repellent.
- In general, repellents protect longer against mosquito bites when they have a higher concentration (%) of the active ingredient. However, concentrations above 50% do not offer a marked increase in protection time. Products with less than 10% of an active ingredient may offer only limited protection, often just 1-2 hours.
- The American Academy of Pediatrics approves the use of repellents with up to 30% DEET on children over 2 months old.
- Protect babies less than 2 months old by using a carrier draped with mosquito netting with an elastic edge for a tight fit.
- For more information about the use of repellent on infants and children, please see the “Insect and Other Arthropod Protection” section in Traveling Safely with Infants and Children in CDC Health Information for International Travel 2010 and the “Children” section of CDC’s Frequently Asked Questions about Repellent Use.
- For more information on the use of insect repellents, visit Mosquito and Tick Protection.
- Wear loose, long-sleeved shirts and long pants when outdoors.
- Spray clothing with repellent containing permethrin or another EPA-registered repellent for greater protection. (Remember: Don't use permethrin on skin.)
