Wristbands are everywhere. They are used for identification by their color coding. They are used for the protection against nausea and there are some for the protection against mosquitoes. Some of the wristbands for the protection against mosquitos contain DEET and some do not. DEET, N,N-diethyl-meta-toluamide, is designed for direct application to human skin to repel insects, rather than kill them. Products containing DEET are registered with the EPA, United States Environmental Protection Agency. The CDC, Center for Disease Control, recommends use of insect repellents when out-of-doors. Studies submitted to EPA indicate that DEET repels ticks for about three to eight hours, depending on the percentage of DEET in the product.
• Products containing 23.8% DEET provide an average of 5 hours of protection from mosquito bites
• Products containing 20% DEET provide almost 4 hours of protection
• Products with 6.65% DEET provide almost 2 hours of protection
• Products with 4.75% DEET were both able to provide roughly 1 and a half hour of protection
As far as wristbands, I could not find many studies on them. Ethiopia is the only place that has provided any information on the wristbands and they are supporting them. They do say that DEET-impregnated fabric strips at a concentration of 1.5 mg/cm(2) provided 4 hours of complete protection against mosquito bites and the reduction of man-landing rate varied between 51.21 and 100%.
The present data suggest that DMP, dimethyl phthalate, treated wristbands are most promising against both day and night-biting mosquitoes and significantly reducing the man-vector contact. Therefore, it could serve as a potential as means of personal protection device against insect nuisance biting and insect-borne disease when and where other kinds of personal protection measures are impossible and impracticable, according to College of Public Health and Medical Sciences, Jimma University, Jimma, Ethiopia.
