Protect your Camp with Thermacell Radius Zone Mosquito Repeller

Thermacell Radius Zone Mosquito Replant Review

The boy looked like he had chicken pox, mosquito bites peppering his neck, lower legs, arms. The wife wasn’t much better. Our summer camp in the Tetons had become a nightmare, trying to hide from the ravenous horde, crouching over our campfire hoping the smoke would protect us. It didn’t. That was last summer. So when I got a chance to test out the Thermacell Radius Zone Mosquito Repellent, I jumped at it. We planned a lakeside backpacking trip and left behind all other no-see-um goos. Either this would work or I’d hear about it from my itchy family for weeks.

Thermacell Radius Zone Mosquito Repellant Review

For all you chemistry geeks out there, the active ingredient is Metofluthrin, an odorless, DEET-free neurotoxin that specifically takes out mosquitoes. Supposedly it can work against other bugs too but not as well. But yes, it is neurotoxic and you’re advised against rubbing it on your body. That said, on one July camping trip into the Winds a few years ago, we brought a bunch of organic mosquito repellent and, as a backup, some DEET. The lemon-whatever-juice organic repellent worked as well as all such organic compounds – that is, it didn’t. So we went with the DEET, covering our bodies, our clothes, even our tent fly. Which led to my wife waking up in the middle of the night with a pounding headache and thereby ending our camping trip at first light. On our most recent backpack, camping next to a lake in the Gros Ventres, we set up the Thermacell Radius Zone Mosquito Repellant and were headache-free.

More importantly, it worked.

The best test subjects I know are my wife and my son. After a lifetime of playing outdoors and neglecting moisturizer and sunscreen, my skin is leathery. My wife and my son, on the other hand, have skin like mana for skeeters so from June until September we can only camp up very high and away from any bodies of water. On our muggy trip to camp alongside Goodwin Lake, we set up the Thermacell Radius Zone next to our campfire/cooking/eating zone. Rebecca the skeptic said there was no way it would keep the bugs (that this summer has been worse than I had ever seen them) from eating her alive. And that was true, the bugs feasted when setting up the tent when getting water when sitting in our camp hammock. But when in the Radius’s 110-square-foot protection zone, the swarm thinned to 1 or 2. We were cocooned inside an invisible force field neither seen nor smelled nor felt except when you stepped outside and immediately were under attack.

Plus it weighs 7 ounces. 7. That’s less than a respectable-sized container of mosquito spray. The size of the Thermacell Radius Zone is about the same as a solar recharger so you put in the refill, slide the operating button to lock, and boom, you’ve got a super mosquito shield fitting comfortably in the pack. It’s also airplane safe so if you’ve got upcoming trips to warm climates – Africa, definitely Brazil, South America in general – this is a no-brainer in your checked luggage. My only advice is to bring a recharger. And if you’ll be traveling for any serious amount of time, bring a few refills.

What can be Fixed?

The biggest drawback of the Radius Zone is how fuel- and repellent-intensive this is. The time limit of the bug juice that comes with this is 12 hours. You can buy a 40-hour refill for around $20 and while I hate the idea of all the plastic garbage this may create, I’d suggest picking up a few if you’re planning on camping in some buggy areas. The Radius itself runs out of power in 6 hours. That’s right, six. It can run while recharging and since it’s (like everything else) USB chargeable, you can bring your solar recharger and theoretically operate it until it drains the Metofluthrin cartridge. But yeah, 6 hours running time with a 12-hour cartridge likely wouldn’t get you through a two-night camping trip. So plan accordingly.

Overall Review

It’s pretty archaic to think that when most of us are camping in buggy climates, we’re covering our bodies with the same crazy chemicals we’ve been using for decades, basically bathing our flesh in pesticides. There have been countless proposed solutions to repelling mosquitoes, urged on by everything from mere convenience (it sucks to get bit by mosquitoes) to dire health issues (malaria and Zika come quickly to mind). And the globe is warming, with one of the canaries in the coal mine being a proliferation of mosquitoes living at higher elevations and for longer durations (with mosquito-borne illnesses already appearing in pets in geographic locations where a decade ago vets wouldn’t have seen them at all, like the increased occurrence of heartworms in dogs up here in the Tetons). Thermacell is answering the call with a line of innovative and diverse mosquito-repellent solutions made for the 21st century and beyond. And the Thermacell Radius Zone ($49.99) is sure to be the outdoors person’s friend as it blends portability, effectiveness, and decreased toxicity into one rugged, easy-to-use unit. While I have some issues with the time restraints on both the charge and the repellent, no doubt this product will keep getting more efficient. For now, it minimizes deleterious effects but works – actually works – and that’s better than any comparable alternatives I’ve tried.

And while your mind’s likely not on mosquitoes given the Starkian imminence of winter, not only would picking one of these up inspire you (give you an excuse) to maybe go somewhere tropical to try it out, it also makes a perfect stocking stuffer for the adventurer on your list. That’s right, I’m already on the lookout for Christmas.

  1. Hi Dana,
    I’m still using this. Having grown up in Baltimore, I know how bad mosquitoes can get back there so I’ll admit we have considerably less of a problem here (unless camping next to a lake or a marsh, though mosquitoes have been proliferating a bit). But it works great and I haven’t seen any neurotoxic side effects. It is DEET-free and you definitely notice the difference with lack of headaches, no smell in the nose, etc… so it’s for sure less toxic than most everything else that actually works, and from everything I’ve read it’s pretty harmless to people as long as you don’t get it on your skin. Plus it should disperse upward regardless of wind. That said, I’m definitely not a neurologist. I totally understand your concerns given the unfortunate circumstances with your nephew; it might be an idea to ask your pediatrician their thoughts on Metofluthrin exposure given your airflow, the amount of time you’re planning on using it and the age of your children. I’ve been using it an average of once a week over the summer months for the past few years, but again, that’s usually if I’m camping or fishing with my son.

  2. Hi! Thanks for writing this review. I know it’s from a couple years ago and I’m curious if you and your family are still using this thing. We live in NYC and have a very very tiny enclosed backyard that has very little air flow flow and lots of mosquitoes come June. This seems like a great solution but I worry about the neurotoxin load with our kids, in particular, and in a space where, again, there’s not much wind happening. We do have a nephew that passed away from a brain tumor three years ago, so admittedly it’s more on our minds than perhaps others. Do you feel like it’s been a safe product all in all?
