Field Evaluation of Two Topically Applied Insect Repellent Products Containing IR3535 Against Mosquitos in Louisiana

Intervention / Treatment
Detailed Description
A single-site field setting study using healthy volunteers to test two insect repellent product formulations (lotion, and wipe) against mosquitos.
Subjects will have repellent applied to one lower limb at a standardised dose rate to account for skin area. They will then expose this area only in a field site where mosquitos are recorded landing at a rate of 5 mosquitos per 5 minute or higher. The exposure period will last five minutes and all mosquitos landing on the exposed skin will be collected using an aspirator. 5 minute exposure periods will be repeated every half hour for 14 hours for the lotion and 13 hours for the wipe, or until median CPT can be established by more than half of subjects reaching treatment failure.
