May 25, 2010 -- Consumer Reports Health has issued a new ranking of the six repellents it says are best to ward off mosquitoes and deer ticks.
The magazine says it tested 10 insect repellents in an outside laboratory, where volunteers let deer ticks crawl on them and also exposed themselves to mosquitoes.
Six of these repellents earned a "recommended" rating from Consumer Reports. These six repellents, along with their active ingredients and cost, are:
Others tested included:
Consumer Reports Health says that the Environmental Protection Agency (EPA) has judged DEET to be safe when used as directed, but that it has caused rare toxic reactions when not used as instructed. The EPA also says DEET shouldn't be applied to babies less than 2 months old.
The American Academy of Pediatrics has advised against using repellents with DEET concentrations higher than 30% on any kids. And Consumer Reports Health says no one should use a repellent with more than 30% DEET.
The top six repellents protected against deer ticks and mosquitoes for seven hours or more, Consumer Reports says in a news release.
Tips to Prevent Insect Bites
And people who travel outside the U.S. might run into mosquitoes that carry malaria, yellow fever, or dengue fever. Ticks, it says, also can spread Lyme disease, human babesiosis, and Rocky Mountain spotted fever.
The magazine says people should follow directions and use their hands to apply the repellent to the face. It urges people to keep the repellent out of eyes, mouths, and cuts and to use just enough to cover exposed skin.
Though the labels of some repellents suggest the repellents can be used on clothes, most of the repellents tested damaged leather and vinyl, and some stained synthetic fabrics.
Consumer Reports recommends taking these steps for extra protection from insects:
Consumer Reports points out that the CDC recommends that people avoid products that mix sunscreen with DEET insect repellent; sunscreens are meant to be used in plentiful amounts, which could expose people to high amounts of DEET.
