The fantasy of gorgeous summer hangouts can be ruined by the reality of slapping away mosquitoes. We know that citronella candles and mosquito traps don’t work, and though many bug sprays do work, you don’t always want to be slathered in them when you’re socializing outdoors. We’ve recommended Thermacell products for five years because they are compact, easy to use, and effective.
After spending 65 hours researching a category full of marketing hype and debunked methods, we found that the Thermacell products stand out by actually working. We recommend four different Thermacell products in our guide to the best mosquito control gear for your patio or yard, two for home use and two that are better suited for camping or hunting.
Thermacell makes devices that work like diffusers, using heat to vaporize a small amount of insecticide into the air to create a bug-free zone. The active chemical is either metofluthrin or allethrin, which in numerous studies have proved to be an effective spatial repellent for mosquitoes. They have both undergone thorough vetting by the Environmental Protection Agency and other regulatory agencies around the world, and it’s deemed safe for this intended use.
With a rechargeable battery, long-lasting repellent supply, and simple interface, the E90 is easier to use than other spatial mosquito repellents.
Our testing confirmed the company’s claim that the Thermacell E90 Rechargeable Mosquito Repellent protects just over 300 square feet (about a 20-foot diameter circle) in still conditions. This repellent’s simple interface and rechargeable lithium-ion battery (with 9 hours of battery life) make it convenient and easy to use. The E90 comes with a 12-hour repellent cartridge, but 40-hour cartridges are also available.

The Thermacell LIV is a large-scale system that can protect a big area from mosquitoes.
*At the time of publishing, the price was $700.
The Thermacell LIV Smart Mosquito Repellent System is a substantially bigger investment towards larger-space coverage. It consists of 3, 4 or 5 metal emitters that look like high-end landscape lights. The devices are connected to an app which provides total control over the system, including turning the repellers on and off, putting them on a schedule or a timer, checking the amount of repellent remaining, and even changing the color of the little lights on the repellers. It can also be connected to a smart home system.
Thermacell’s EX90 has the same mechanics as the E90, but with a few features that make it a better option for camping or other outdoor activities.

Internally, the EX90 is identical to the E90, but the EX90 has a more compact design, rubbery grip areas on the sides, a lanyard and carabiner (to hang it from a branch), and a locking lid (the E90’s lid is held in place with magnets). The EX90 costs the same as the E90, so it’s really a matter of if you think you’ll need the added durability of the EX90.
The MR450 is more rugged and portable than our other picks. And its butane fuel source makes it better for situations like extended camping trips. But it isn’t as convenient as having one with a lithium-ion battery.
We really only recommend this model if you need something even more rugged and durable for long camping trips. The MR450 runs on a butane cartridge, which is faster to burn through and harder to replace than simply recharging a battery. This model also uses four-hour repellent pads, which last for far less time than repellent cartridges, and it’s harder to tell when they’re used up.
Don’t expect your Thermacell to work the moment you turn it on. You need to turn it on about 10 to 15 minutes before you plan to be outside, to allow the repellent to “saturate” an area.
It won’t work in windy conditions. Thermacells are all about building up an area of protection around the emitter, so it just takes one good breeze to blow it all away.
Also, be careful when opening the repellent replacement cartridges. Some users have accidentally broken the cartridge wicks when they didn’t pull the cap straight up—and if the wick breaks, the cartridge no longer works.
The refill cartridges are all compatible among the E90, the E55, and Thermacell’s older Radius models. But you want to choose the refills that are labeled Thermacell Mosquito Repellent Refill, as they have a higher concentration of repellent, so they offer better protection. If you already own a Radius, you don’t need to upgrade. The E90 cartridges fit and will increase the effectiveness of the older unit.
