Which Thermacell Repellent Devices are we talking about here?

Thermacell makes two main versions of their mosquito repellent: the rechargeable lithium ion-powered version (the most common) and the fuel-powered version. They both work very similarly. We’ve only had the chance to review the lithium-ion version (rechargeable battery), but they work in a similar manner.

Here’s how the Fuel-Powered Thermacell Devices Repel Mosquitoes

Fuel-Powered Thermacell Mosquito Repellent devices are an incredible way to keep mosquitoes away – they are a smart mosquito repellent system – much smarted than bug spray.

They work by creating a 15-foot mosquito protection zone from mosquito bites and just annoyance. . Thermacell’s zone repellent technology eliminates the need for messy lotions or sprays, stopping mosquitoes before they can bother or bite you. This fuel-powered Thermacell technology uses heat activated repellent to create an invisible, scent-free, zone of protection from mosquitoes.

The devices are powered by a small fuel cartridge that provides cordless, portable heat that is directed to a metal grill. A small repellent mat saturated with repellent is inserted on top of the metal grill. Heat (via a butane cartridge) disperses the repellent from the mat into the air, creating the zone of protection.

Three Mats are pictured here – the small mat (repellent mat) holds the repellent.

How the Battery-Powered Thermacell Devices Repel Mosquitoes

We tested the rechargeable battery version and it works in a similar, but slightly different way.

The rechargeable version doesn’t use repellent mats – instead it has fluid to help you not be eaten alive.

We prefer the battery version over the butane cartridge-power version because it doesn’t require a separate heating element and repellent mats. Both need to be replaced (the repellant mats last about 4 hours each).

What are Thermacell Mosquito Repellent Machines and how do they work?

Thermacell makes spatial repellents that work like diffusers to emit a repellent into the air and create a bug-free zone. Think of it like a Pura Smart Diffuser, but instead of spreading a smell you love, it’s a smell the mosquitos hate (and you can’t smell at all!).

This means you don’t have to douse yourself with smelly, sticky spray. The Thermacell Mosquito Repellent have become my most valuable tools for enjoying outdoor life.

The E-Series is their newest line, is a compact and convenient device (smaller than my cell phone) that uses heat to vaporize a little vial of liquid repellent. The active chemical in the liquid is metofluthrin (what’s in the repellent cartridges), which in numerous studies has proved to be an effective spatial repellent for mosquitoes.

Metofluthrin has undergone thorough vetting by the Environmental Protection Agency and other regulatory agencies around the world, and it’s deemed safe for this intended use.

This handy dandy device creates a zone of protection from those pesky pests. And best of all, it’s battery powered, so you can take it with you wherever you go. No more smelly mosquito coils or poisonous pesticides. Just sweet, sweet relief from those blood-sucking bugs. 

What is Metofluthrin – the active ingredient?

Thermacell’s repellent is made with metofluthrin, a pyrethroid that’s been shown to repel up to 97% of mosquitoes in field tests. Thermacell Radius products produce a vapor that protects an individual or area from mosquitoes. The effectiveness of the vapor is reduced by air movement, so it’s best to use Thermacell Radius products in areas where there is less wind, if possible.

Metofluthrin is neurotoxic, so it’s not meant to be applied directly to human skin. If you’re looking for an effective way to keep mosquitoes away, Thermacell Radius is a great option.

Thermacell Mosquito Repellent Machine Review: Does it REALLY work?

The quick answer is YES. These devices really work.

Costco had Thermacell Radius on sale so I bought one to test out. Turns out it’s everything you need to keep mosquitoes away with the simple push of a button. Plus, it’s compact, rechargeable, and TSA-approved. 

The Radius provides a 20-foot zone of advanced mosquito protection. Additionally, the Radius is rechargeable and features a 6.5-hour battery. Plus, the Thermacell Radius comes with 12 hours of mosquito repellent included.

It’s been independently tested and EPA reviewed for safety & effectiveness, the Thermacell Radius repels mosquitoes, including those that may transmit Encephalitis, West Nile Virus, and Zika Virus. So, if you’re looking for an easy-to-use and effective way to keep mosquitoes away, the Thermacell Radius is a great option!

Better yet, it’s pet friendly (and human-friendly, too).

How does it compare to other mosquito repellants?

The Thermacell Radius is the best mosquito repellent because it actually works. The repellent cartridge lasts 40 hours (12-hour cartridges are also available), and it’s nearly as good at stopping mosquitoes from bothering you as a full application of a spray repellent.

Plus, it’s easier to use than other spatial mosquito repellents. So if you’re looking for a mosquito repellent that actually works, the Thermacell Radius is your best bet.

Our Test and Use Case

We work on this blog and YouTube channel after the kids go to bed. Often, I spend time in the garage putting together eBikes.

In the winter, obviously, mosquitos aren’t a problem at all. But in the summer – they are – BIG TIME.

It also get very warm in the summer, so I have to open the garage doors if I don’t want to sweat like a pig (mosquitos also love carbon dioxide, so more sweat = more carbon dioxide production).

After the sun set, I opened up the garage doors and I set up the Thermacell and let it “do it’s thing” (as the not-so-cool kids say) for 15 minutes, per the instructions.

After an hour, I had not seen a single mosquito. Not one. And, I was surprised how well it worked because there were quite a few buzzing around before I turned on the Thermacell Radius.

I also did not notice any scent coming from the device, which is great because some mosquito repellents can be quite stinky (not to mention unhealthy).

To test it out further, I went outside the next day without the Thermacell Radius to see if mosquitoes would bite me. They did – within seconds of being outside. So, yeah, this thing works!

The day I tested it out, the only time I felt a mosquito was when I was setting up the Thermacell for the first time.

That’s pretty remarkable.

Other Thermacell Device Options

Thermacell also has some really cool options like their LIV System – which is a super smart mosquito repellent system.

The Thermacell LIV is the first smart mosquito repellent system of its kind. It’s a backyard staple for entertainers, smart home enthusiasts, and anyone who wants to enjoy a calm evening outside without mosquitoes ruining it.

The Thermacell LIV Smart Hub powers and controls up to five repellers, connecting to your home network unlocks LIV+ features.

Repellers are points of protection. Place these near areas you use most to protect larger, or multiple areas. Repellent keeps the mosquitoes away, and cartridges placed in repellers create protection zones that repel mosquitoes. Thermacell’s LIV is the perfect addition to any backyard!

The Donwside of Thermacell Devices

There are only three downsides of the Thermacell Devices:

  1. They take about 15 minutes to full “work”
  2. You have to purchase repellant refills – that are about $18 for 36 Hours of protection
  3. It doesn’t work as well in windy conditions (but neither do mosquitoes!)

However, if you’re going to spend time outdoors, Thermacell is worth the investment – because it actually works!

Plus, Thermacell offers a 100% satisfaction guarantee. So if you’re not happy with your purchase, you can return it for a full refund.

We highly recommend Thermacell devices to anyone who wants an easy-to-use and effective way to keep mosquitoes away.

New Models: Meet the e-Series

We just got our hands on the new EL55 – which is very similar to the previous version, with a visible improvement: a light!

Yes, this slightly larger version of the repeller included a light, too.

It also has a slightly bigger battery, with 9+ hours of time (when not running the light).

The light is even independently controllable outside of the repellent. That’s pretty cool, too.
