Thermacell Patio Shield Mosquito Repeller; Highly Effective Mosquito Repellent for Patio; No Candles or Flames, DEET-Free, Scent-Free, Bug Spray Alternative; Includes 12-Hour Refill

I have several of these units and can't say enough about how well they keep mosquitoes and gnats away. I do use 2 units for my 20 x 12 foot deck. Manufacturers always tend to over exaggerate the effective range on products like this. I use the half rule. If it says 15ft range I assume its going to be 7 maybe 9 feet which is why I use two units at the same time. If the bugs are really bad I sometimes add a 3rd unit but they do keep the bugs away. It's important to realize that you should turn these on and place them outside at least 15 minutes before you enter the area. This is actually what the Manufacturer suggests anyway. They do take time to heat up and for the vapor to start coming out of the units and to spread around the sitting area. As for the blue pads, I hear some complaints they turn white in less than 4 hours. Turning white doesnt mean its not working. The oil is still being emitted even when it turns completely white. In fact just having them in the sun and humidity will make them turn white but it still takes about 4 hours to exhaust the pad. One other thing to note is once you open the package the clock starts ticking. If you used it on day one for 2 hours and then don't use it for a couple days they will have dried out and no longer work and a new pad needs to be inserted. With that said its not the greatest if you just plan to sit out for an hour but they are still the best solution I have found. I ordered the rechargeable unit that uses a liquid cartridge instead of the pads to see if these are better for shorter usage times. I'll update this review once I try it. Update on Rechargeable version with the liquid cartridges... This is the way to go! Theybwork just as good as the butane models with the pads. They actually heat up faster too. When I'm done with them I turn them off and they are good to go even days later since the liquid doesn't evaporate from the wick. No pads pads or butane cartritges to deal with. When repellent cartridge is empty just drop a new one in. Couldnt be simpler. Note! The cartridge that comes with the unit is only partially filled, just like when you buy a new printer. The replacements are completely filled.

⭐⭐⭐⭐⭐ Actually Works – A Must-Have for Mosquito-Free Evenings! I was skeptical at first, but this Thermacell Patio Shield seriously works. I’ve used sprays, candles, and torches before, and none of them gave me the consistent, scent-free protection this device does. 🦟 Effective Mosquito Protection: Once activated, it takes about 10–15 minutes to kick in, and after that, you’re in a noticeably mosquito-free bubble. I use it on my back patio during the evenings and it keeps the bugs away—even during peak summer mosquito hours. The 15-foot zone is accurate, but make sure there’s not a lot of wind for best performance. 🌿 Scent-Free & No Spray: The best part is that it’s completely odorless. No sticky sprays, no harsh smells, and nothing to apply to your skin. Perfect if you have kids or pets around. 🔋 Easy to Use: It’s simple to set up—just insert the repellent mat and fuel cartridge, twist the base, and the little light lets you know it's on. The included 12-hour refill lasted through a weekend of evening use. Refills are easy to find and reasonably priced for the convenience. ✅ Pros: Actually repels mosquitoes effectively Odorless and spray-free Easy setup and compact design Stylish enough to sit on any outdoor table Safe around food and drinks ❌ Cons: Protection takes 10–15 minutes to activate Wind can affect the coverage zone Only covers a 15-ft radius—you may need more than one for large spaces 🏡 Final Verdict: If you're tired of getting eaten alive while trying to enjoy your patio or backyard, the Thermacell Patio Shield is a game-changer. It’s effective, clean, and low-maintenance. I’ve already bought a second one for our front porch!

So, I live in the South and during the summers, it gets hot, humid, and mosquito-ridden. During these times, I like to stay inside as I may be the biggest mosquito magnet there is. It doesn't help that I have allergic reactions to them, so win all around for mosquitos. I have used many different mosquito repellants separately and in combination with others. I will say that this is pretty good and one of the best. It does a good job of repelling mosquitos in a certain radius (not so sure if it's as big as advertised, but it is big enough). I like to set it out when I'm with family on the porch, but I have to make sure that I set it out in advance and still use other repellants (long sleeves/pants and spray). Even with all these preventative measures, I still get bitten but it does feel like a lot less. Buy to use for camping or eating outside in one area. However, it does not work well if you intend to keep on you and walk around. It's a bit larger than a soda can (more like a small thermos) but it is portable.
