WIRED Reviews Mosquito Repellents: Thermacell, LIV, and BiteFighter Tested for 2026
In a review by Christopher Null for WIRED, mosquito repellents are assessed, revealing that devices outperform traditional traps and sprays. The standout choice is Thermacell's E-ZoneGuard, a USB-C rechargeable model that generates a vapor cloud extending 10 feet and lasts for 36 hours, with refills priced at $39. The butane-powered Fuel-Zoneguard Base offers coverage of 7½ feet for 12 hours, with $19 refills. For expansive spaces, the LIV Smart Mosquito Repellent System 2.0 utilizes metofluthrin and necessitates professional installation. Tiki's BiteFighter Plug & Repel activates a metofluthrin pod and requires a repeller every 12 feet, with pods available for $10 for 48 hours. Products like Home Defense Mosquito Kill & Prevent and Mosquito Dunks are ineffective, while professional spraying can exceed $2,000 annually. Globally, there are 3,200 mosquito species, including 174 in the US.
