    Insect Repellent--how to use it safely
    Jennifer Shu, MD posted:
    Insect repellents can be useful to prevent mosquito-transmitted diseases such as West Nile Virus and the plain nuisance of itchy bites. Here are a few tips when it comes to insect repellent:

    Unlike sunscreen, which is important to reapply every few hours, insect repellent generally should be used just once a day and then washed off before bedtime.

    Check labels for age recommendations. DEET is approved for infants over 2 months; oil of lemon eucalyptus is not recommended until at least 3 years.

    Higher concentrations of DEET last longer than lower ones (10% DEET is effective for 2 hours while 24% is effective for about 5). The American Academy of Pediatrics recommends that children use DEET concentrations below 30%. DEET and picaridin tend to last longer than plant oil-based repellents.

    You can also use netting to physically keep bugs away from your baby.
