Thermacell makes mosquito repellent products that repel mosquitoes without using sprays, creams, or chemicals.

Thermacell portable and stationary mosquito repellents work by creating an invisible 15 foot shield around you and your family.

Each device is powered by a unique fuel source and repellent mat combination that wards off intruding mosquitoes without the use of harmful chemicals such as DEET.

Are they worth the hype?

Mosquito prevention without greasy sprays and creams seems too good to be true.

We decided Thermacell’s line of products was worth a full review. If mosquito bites can be avoided without using harmful chemicals, we’re in.

Let’s take a look at Thermacell’s offerings and see what makes them some of the best selling mosquito repellent products on the market:

1. Thermacell Patio Shield

The Patio Shield has been heralded by other pest control experts as one of the best backyard mosquito repellents.

We can’t disagree.

At a price comparable to a large citronella candle, the Patio Shield is claimed by Thermacell to by 6 times more effective that 42 citronella candles (42! That’s a lot of candles!).

Remember that you will have to replace the fuel cartridge and repellent mats, which make the Patio Shield work.

USER REVIEW: “I live in Jersey and have a small pond in my backyard – so a ton of skeeters. Set up 2 of these on my porch and so far have only been bitten once this summer.”

Each fuel cartridge lasts 12 hours and each mat lasts 4 hours.

2. Thermacell BackPacker

If you often go fishing, or camping, the Backpacker is a great mobile mosquito solution.

While it takes up only a small amount of space in your gear, like its big brothers, it creates a 15 foot shield of mosquito protection.

A nice added feature is that it is effective at an elevation of 7,000 feet.

Provides 90 hours of repellency off of a 4 oz. gas canister that you may already have in your camping gear.

3. Thermacell Portable Mosquito Repeller

The Portable Mosquito Repeller uses the same technology found in other Thermacell products, just in a smaller size.

Like the Backpacker, the Portable Mosquito Repeller is a great option for those that enjoy outdoor activities like hiking, camping, boating, and hunting.

Weighing only 6.4 ounces, this option provides a 15 foot mosquito free zone for 12 hours.

It is offered in four colors: black, hi vis, olive green, and orange/grey.

What’s Good?

  • No mosquitoes to clean up after operation.
  • DEET-free & odor-free.
  • 15 feet zone of protection.
  • Fuel cartridge lasts up to 12 hours.
  • Affordable cartridge and mat refills.

What’s Wrong?

  • Requires cartridge and mat replacements.
  • Cannot bring on airplane due to fuel cartridge.
  • Not as effective at higher altitudes.
  • Not recommended for indoor use.

How It Works

Thermacell mosquito repellents use heat to create an invisible, scent-free, zone of protection. They are powered by a small activated cartridge which provides cordless, portable heat, directed to a metal grill. Over this grill, a small mat imbued with a repellent is inserted, which disperses the repellent from the mat into the air, when heat is applied.

Thermacell comes in two power varieties:

  1. Fuel-Powered
  2. Battery-Powered

Let’s take a look at the advantages & disadvantages of both technologies.

4. Fuel Powered Thermal Repellents

Fuel powered repellent uses a specific type of mat to repel mosquitoes. The mat contains 21.97% of Allethrin and 78.03% of other ingredients. They also contain petroleum distillates.

If you’re fond of hunting, camping or just spending a lot of time outdoors in the fresh air, but hate dealing with mosquitoes, you can use a Thermacell fuel-powered mosquito repellent. 

These models work by using heat activated repellent mats to create a zone which is scent-free. This zone keeps mosquitoes away, however, you need to wait at least for 10-15 minutes for it to fully activate and create a 15 foot zone around where you’re sitting. The drawbacks of this repellent is that on regular use it can get pricey because of fuel-cartridge and mat refills.

5. Battery Powered Thermal Repellents

The Thermacell Radius Zone Mosquito Repellent, uses a lithium-ion battery instead of fuel-cartridges. 

Thermacell Radius Zone Review

The repellent does need to be intermittently refilled. The refill contains Metofluthrin as an active ingredient to create a mosquito free zone. Two types of refills are available, one works for 12 hours while the other one lasts 40 hours.

The included lithium batters lasts 6 hours in a single charge. Apart from everything else, it is air travel friendly. While Thermacell’s fuel cartridge models cannot be brought on a plane, the Radius Zone battery is acceptable. Also, it was voted as Grand Award Winner in Recreation for Popular Science’s 2018 BOWN Award.

Thermacell’s fuel and battery mosquito repellents are registered with the United States Environmental Protection Agency (US EPA). Thermacell over the past 20 years has protected millions of people from the harmful effects of insects.

Customers Reviews – How’s It Stack Up?

We scoured online reviews and ran the Thermacell products by our readers.

The general consensus?

While it does cost some extra money to refill the cartridges and mats, most reviewers have found Thermacell mosquito repellents to be largely effective at keeping away mosquitoes. Of course, no mosquito prevention technique is perfect, but most reviewers have been happy with the results.

Fewer mosquitoes with no sticky sprays or creams.
