Thermacell recently has introduced “The Thermacell LIV Smart Mosquito Repellent System [cost $699 for 100 hrs protection] that creates an installed, large area of mosquito protection customized for your outdoor space. This smart system is all you need to enjoy season-long mosquito protection year after year. No batteries, no sprays on your skin. LIV lands in March 2022.” This system apparently can interface with Amazon’s Alexa or Google Assistant to turn on/off using voice commands. The repellent is not new and is 5.5% metoflutrhrin [C18H20F4O3 ] which is a type I pyrethroid ester approved as a special repellent. Buhagiar et al. (2017) previously evaluated this compound indoors against Ae. aegypti and found 100% repellency and mortality (https://parasitesandvectors.biomedcentral.com/articles/10.1186/s13071-017-2219-0).
