It's going to be that time of year again soon so for the sake of your loved ones make sure you have the facts: 

Repellents that contain DEET (N, N-diethyl-m-toluamide), Permethrin, or Picaridin (KBR 3023) provide protection against mosquitoes.  In addition the one "Natural" repellent that provides as much protection as low concentrations of DEET is Oil of Lemon Eucalyptus (p-methane 3, 8-diol, PMD).  Most other natural repellents do not provide the same level or duration of protection as DEET or Permethrin.

DEET products should not be used on infants under 2 months of age.

Children older than 2 months should use products with DEET concentration of 30% or less.

DEET products are available in concentrations up to 100% so read the labels carefully.  Products containing more than 30% do not provide much additional protection, however they will last longer.  Per study information, a concentration of 4.75% of DEET lasts about 1.5 hours.  A concentraion of 23.8% DEET lasts for up to 5 hours (Length of protection time can be effected by temperature, perspiration and water exposure).

Permithin products are intended to use on items (clothing, shoes, camping gear, etc.)  It should not be applied to skin. 

Oil of lemon eucalyptus should not be used on children under the 3 years old.

Remember to read instructions on the product label carefully.  Use just enough of the repellent to lightly cover exposed skin and/or clothing.  Putting on a larger amount does not make the product work any better.  Don't use repellents on cuts or irritated skin.  Don't use near the mouth or eyes and use sparingly around the ears.  When using spray products, spray onto your hands first and then apply it to the face.  When you come inside, wash your skin and the clothes that had repellent on them.

If you suspect that you or your child is having an adverse reaction to a repellent (develop a rash, etc.) then remove any treated clothing; wash the affected area with soap and water; and contact your doctor or local poison control center.  If you go to the doctor, then take the repellent with you so the doctor can review the label information.
