It is imperative to put roadblocks between the mosquito and you. Our humid area is breeding ground for mosquitos.

Mosquito Repellant Recommendations

With summer soon approaching and increasing concerns and awareness about the spread of viruses from mosquito bites, we at Calais Dermatology would like to make recommendations of insect repellents and protective clothing.

The CDC (Center for Disease Control and Prevention) is encouraging people to take measures to prevent mosquito bites. They recommend EPA (Environmental Protection Agency) registered-insect repellents. According to the CDC, repellents should have one of the following active ingredients:

  1. DEET
  3. IR 3535

DEET has been the best insect repellent invented by man (in 1957). In concentrations of 20-50%, it is effective and safe. Consumer Reports Magazine says the more-effective products against the mosquito that spreads the ZIKA virus, Aedes species, is Picaridin. Two products recommended are Sawyer Picaridin Insect Repellent and Tinder Corporation, Natrapee 8 Hour. Each product contains 20% Picaridin. Also, Consumer Reports recommends OFF DEEP WOODS VIII (S.C. Johnson and Son with 258 DEET.)


For patients who are worried about DEET and other insect repellent chemicals, lemon eucalyptus products are recommended. However, it is not recommended on children younger than 3yrs old. For children with sensitive skin, treatment of their clothing and head gear (hats, etc.) with Permethrin is recommended.

Remember that the mosquitos are most active in the early morning hours around sunrise and late hours around sundown.

Please read the following CDC Recommendations for Prevention. On May 13, 2016, the CDC has announced that they will disperse $85 million in grants to U.S. states and territories to help them prepare for Zika and the associated health outcomes like microcephaly. $25 million will go to 53 states, cities and territories at risk for outbreaks.

Since insect repellents are not 100% effective, protective clothing and even mosquito nests especially around bedding may be necessary. Also, spraying clothing with repellents with DEET is very helpful. There is clothing which has been treated with Permethrin. The protection will last six washes. Since the biting insects, including mosquitos, are attracted to the CO2 (carbon dioxide) emitted, one's head, ears and neck should always be protected. All exposed skin should be treated.
