How it was tested
Laboratory comparison of wearable repellent devices against spray-on repellents using human bait trials.
Summary
Wind-tunnel attraction-inhibition assays comparing five spray-on repellents against wearable bracelets, a sonic device, a clip-on, and a citronella candle for reducing Aedes aegypti attraction.
Key findings
All five sprays significantly reduced mosquito attraction; sprays with DEET (98%) and oil of lemon eucalyptus/PMD (30%) were the most effective. Of the wearables, only the metofluthrin clip-on worked; bracelets, the sonic device, and the citronella candle were no different from no repellent.
Limitations
Laboratory wind-tunnel attraction metric rather than bite-protection time; single species; products tested at one distance.
