Thursday, July 04, 2002Before each test, the readiness of the mosquitoes to bite was confirmed by having subjects insert their untreated forearm into the test cage. Once subjects observed five mosquito landings on the untreated arm, they removed their arm from the cage and applied the repellent being tested from the elbow to the fingertips, following the instructions on the product's label. After the application of the repellent, subjects were instructed not to rub, touch, or wet the treated arm. Repellent-impregnated wristbands were worn on the wrist of the arm being inserted into the cage. Subjects were provided with a standardized log sheet to ensure accurate documentation of the duration of exposure and the time of the first bite. The elapsed time to the first bite was then calculated and recorded as the "complete-protection time" for that subject in that particular test. The winner of the contest was OFF Deep Woods, coming in with mosquito protection for a mean of 301.5 minutes (give or take thirty) and the loser was Gone Plus Repelling Wrist Bands at 0.2 minutes (give or take 0.09). Skin-So-Soft products and other citronella-based repellants didn’t come out so well, either, ranging from two to twenty minutes of protection, but a soybean-oil based product called Bite Blocker for Kids did pretty well, providing protection for 94 minutes (plus or minus 42). That was comparable to the DEET based OFF product for children, Skintastic for Kids. Just some food for thought for this summer holiday. posted by Sydney on 7/04/2002 07:28:00 AM 0 comments 0 Comments: |
