Product Description

Mosquitos are no small problem - they can ruin a good time with painful bites, bothersome buzzing, and days of itching afterwards. Until now, sprays, lotions, torches, DEET and citronella have been the only options for fighting mosquitoes. We started Thermacell because we wanted a better way to fight mosquitoes. From humble beginnings, our team of entomologists, researchers, and outdoor enthusiasts has over 100 years of combined experience fighting mosquitoes. Enter Thermacell. For the backyard and beyond, Thermacell Patio Shield is easy to use and provides hours of scent-free, mess-free, DEET-free defense against mosquitoes. With no batteries or cords needed, the Patio Shield is convenient, portable mosquito protection, ideal for entertaining, gardening, camping, poolside, and more. At Thermacell, our mission is to change the way the world fights mosquitoes, and we’ve been doing it for over 20 years. Headquartered outside Boston with distribution centers in Georgia, we’re leading the way with better, worry-free, more environmentally friendly solutions to biting insects. With global distribution in 30+ countries and tens of millions of repellers sold, more and more people around the world count on Thermacell to make outdoor time even better.

5 Stars
Surprisingly, it works!
I was very skeptical of this, even after reading all the positive reviews. It just doesn't seem like anything keeps mosquitoes away except for spraying yourself with repellent. I have to say, I was pleasantly surprised and still am a little shocked that it actually seems to work. I have a pool and I work on my laptop out on the patio next to it, and by 4:30 PM I usually have to go inside because I start getting bit by mosquitoes. For the last week I have been sitting out there well into the 6 to 7 PM range without getting bit, with this little Repeller sitting next to me. I still almost can't believe that that is the reason why I'm not getting bit and that it must be a fluke, but so far it really does seem to work. I will update my review if I notice a change but right now I am pleasantly surprised and pleased with this purchase. I bought extra of the Pads and fuel, because you do run through them quickly if you're leaving it on for hours at a time, especially of the pads, which only last four hours. But if it means I'm not getting bitten, I do not care about keeping a stockpile!
