This Thermacell mosquito repellent offers DEET-free, scent-free protection!

We went on a trip to visit family in the Midwest and there were a TON of mosquitos outside, which is a bummer if you are prone to mosquito bites like me.

My sister-in-law had this nifty Thermacell mosquito repellent device on her patio table and I was so impressed by how well it worked that I now have one in my backyard to keep mosquitos at bay! 🙌

Thermacell Patio Shield Mosquito Repeller w/ Refills
As low as $20.97 (regularly $26.99)!

How does the Thermacell mosquito repellent work?

The battery-powered device creates heat with a 12-hour fuel cartridge that warms up and “activates” the small mosquito-repellent mat on the top. It repels without smoke, flames, or citronella, and creates a 15-foot zone of protection against mosquitos.

The unscented repellent mats (3 included) last up to 4 hours each and change color when it’s time to refill.

There is no mess, no DEET, no spray, and no on-skin chemicals. The active ingredient is based on naturally occurring repellents found in plants.

The setup on the Thermacell is easy if you follow the simple directions.

The butane fuel source at the bottom of the device easily screws in and the blue repellent mat slides in at the top. You can purchase more of the mosquito repellent scent-free replacements and fuel cartridges separately when the initial few that come with the unit run out.

Thermacell is perfect for mosquito protection on patios, decks, pools, porches, and while camping!

Hip Tip: If you’re looking for a great natural, organic mosquito and bug repellent for your skin, check out our helpful review of “No-Bite-Me” cream! I purchased it myself to try after Sara’s recommendation, and I agree that it works great.

Thermacell has over 28,000 5-star ratings on Amazon! Check out these reviews:

I am a 100% mosquito magnet. The instructions to put this device together and get it running took me 10 seconds. I live in the country of NC where the mosquitoes are insane. Normally when I step outdoors they latch to me like that is my life’s purpose. I turned on this device and gave it about 15 minutes. I watched mosquitoes attempt to fly up to me and turn around over and over. Don’t walk. RUN and buy this product because I am amazed at how it repels mosquitoes. I am honestly thinking of buying a 2nd one just for layered protection if I have company over. Buy this and thank me later!


This product works within minutes! I could never enjoy evenings on the deck because I am a mosquito magnet! We live on the water so the mosquitos get pretty bad. This little thing has become my best friend. I am on my third summer using these, I even have my neighbors using them as well. Nothing else works like this! Highly recommend!

In my opinion, mosquito-free patio time is well worth the cost of the Thermacell!

If you’re a mosquito magnet like me, definitely consider the Thermacell mosquito repellent shield as an option for added protection outdoors that’s easy to use! I find it to be super helpful in reducing mosquitos on the patio and think you will as well.

    I agree. I have this and it works wonders.

  2. Teah

    I have a different model and I love it. It keeps Oregon mosquitos away. The only issue I have is the refills can be spendy, but I do see them on clearance often and usually stock up when I do.

    • Lina D (Hip2Save Sidekick)

      oh nice! Thanks for sharing Teah!

    • Mama Miller

      Can you tell us what model you did get? Thanks

    • Carrie Fox

      Can you tell us where you see it on clearance?

  3. Olivia

    I bought one at the beginning of summer and I think it’s worth the pricey refills! Mosquitoes LOVE me and I get huge welts from mosquito bites. But this summer I have only gotten one little bite. That’s way bette than the 5-10 each night I was getting before. So totally worth it in my book! Just make sure your kids “forget” and leave it on all night….darn kids.

    • Lina D (Hip2Save Sidekick)

      Ha yes that is a great point! I almost did that myself 😂 Thanks for your input Olivia 🙌

  4. luna

    We had good luck with this product. so many friends have asked me the details for this one.

    • Lina D (Hip2Save Sidekick)

      Thanks for sharing Luna!

  5. Carrie

    I got this and took it camping with us. I have to agree with those who say it does work. I will note that it does not work if it it windy or even really breezy. It works best if you keep it in one place and stay within 15 feet of it.

    • Lina D (Hip2Save Sidekick)

      Thanks Carrie for sharing your experience!

  6. mara138

    Got these last year we love them! I can’t be the person who sits next to it because it irritates my throat. But it is great sitting out back in the evening with no mosquitos!

  7. Vicky

    I was checking if this product could be used to help keep mosquitoes away from our outdoor commnuinty cats but this can be fatal. Please keep cats away from this. Fatal to bees as posted above and fish – in case anyone has ponds.

    • shelleybeaches

      Thank you for saying this! I was going to get one for our patio but the cats spend a lot of time out there. Maybe we can use it for camping.

  8. Mona

    I got it last year and, it works really good. Just remember, you have to turn it on 20 or so minutes before you go out. I’m a mosquito magnet and, couldn’t believe, I wasn’t bitten once. Also stay in the perimeter, that helps.

    • Lina D (Hip2Save Sidekick)

      Thanks for sharing Mona!

  9. kim

    Can you use the same mat more than once if you don’t use it for 4 hours? Or is it once and done? Thanks

    • Lina D (Hip2Save Sidekick)

      I continue with the same one.

  10. Rischelle

    Take the plunge and splurge on this. I’ve been hesitating for over a year. Finally decided to give it a try the last time H2S posted about it, as I have not been able to enjoy my patio for years because the mosquitos are so bad. This thing works! My husband, the forever skeptic, used it without my knowledge so that he and his dad could sit on the patio and they were both impressed. No bites. We live in NW PA and our backyard has an open area surrounded by a lot of trees. We get a nice breeze back there. Still, this worked! I plan on buying the refills soon! Side note – I also purchased the No Bite Me cream advertised on here and it’s worked every time I’ve worn it. Give one of them (or both) a try!

    • Jessica (Hip Sidekick)

      Thanks so much for sharing your honest and helpful feedback, Rischelle! I have had my Thermacell for years and love it so much, I’ve bought a few. I even take it to outdoor events! So happy to hear you can enjoy the your patio area more now! 🥰

  11. Jill

    I have this and it works awesome!! I love it.

    • Trish (Hip Sidekick)

      So happy to hear your loving yours, Jill! Thanks for sharing your honest feedback! 🤗💗

  12. MT

    Thanks for posting! I was curious about refill costs and found an option on Walmart’s site that includes extra refills for a few $ more

    • Trish (Hip Sidekick)

      You’re SO welcome, MT! Glad you were able to find an additional refill option! Thanks for sharing! ❤️

  13. Anne S

    Grabbed one…thanks for the suggestion! Looking forward to trying it out this summer.

  14. Taryn S

    My husband is an avid hunter (in the Midwest and South), and he has used one of the personal clip-on ones for YEARS – he swears by them! Definitely an effective product all around.

    • Amber (Hip Sidekick)

      Oh wow! SO cool to hear how well it has worked for him on his hunting trips! Thanks for commenting! ❤️🤗

  15. Wendy Ann Harwood

    Thanks!

    • Amber (Hip Sidekick)

      You bet!

  16. Mary Ann

    We love these products. They work wonders! We also have some that we take with us while camping!

    • Jessica (Hip Sidekick)

      Yay! Great to hear you’re a fan too, Mary Ann! We love our Thermacell and use it on our back patio and outdoor concerts! SO handy, and others around us always appreciate the lack of mosquitos! 🦟🎉
