E-ZoneGuard Mosquito Repellent Refill, 240-Hr Value Pack | 20-FT Zone; 6x 40Hr Refill Cartidges; Rechargeable; Outdoor Patio Shield; Bug Spray Alternative; Scent Free; DEET-Free

I live in SouthEast Texas, and this thing is amazing! I've purchased two so far, and even in conditions that would normally make you not go outside at all these things work. I'm talking about when mosquitos are so bad that even sticking your arm out of your door for 5 seconds results in 10 mosquitos landing on it... Turn this thing on, let it heat up, place it outside and wait a few minutes, then go outside and place it where you're going to be sitting for a while and let it sit some more before going back. I believe somewhere it says 20 minutes, but even in bad mosquito conditions I've been able to stop from being bit in 10 minutes. There are a couple of issues that prevent it from working as well as I'd like, but they are minimal. The maker needs to make a version with an outside plug and a remote control so you can place a couple of them around your outside area and while still inside hit the remote so that it can warm up and do its thing for the 20 minutes before you go into the thick of it. An app would be even better because then you could track the length of time left on your refill and know when to change it out. The other thing that makes it not work is being in the presence of certain cleaning agents and chemicals. Putting two of these around a car makes it so that you can work for hours without any problems, but the second you spray a bit of brake cleaner they are all over you. Also, apparently when you've just poured Drano it will nullify it enough for you to get bit until the smell goes away. That may mean that other things can nullify it so maybe we should try to make a list somewhere to help people out. Please share the idea of a remote/app if you agree, and if the manufacturer reads this, please make a permanently outside version with app so we can leave it plugged in and activate it before we go outside, but other than that it's awesome!

SLOW shipping. Great product but Amazon uses USPS to deliver this item and it is now two days past when it was supposed to be delivered and I still have not received this item.

These are very handy to use while relaxing in the pool! 100% recommended!

Kind of expensive but they work!

I like this product very much, but it just doesn’t seem to last long enough. I keep buying it and keep using it and that’s the only negative thing I have to say about it. It just doesn’t last long enough.

This is the most economical way to buy the Thermacell refills.

I've been purchasing this product for over 3 years, and it used to be amazing—no mosquito bites at all. However, the batches I've received in 2025 have been disappointing. I noticed the filter now comes in a different plastic container, and unfortunately, the mosquitoes are biting me again. This does not seem to be the same product I've relied on in the past. Buyers, beware!

Works well
