ThermacellMosquito Repellent Refills; Compatible with Thermacell Backpacker; Highly Effective, Long Lasting, No Spray, Scent, or Mess; 15 Foot Zone of Mosquito Protection

More product to fuel longer camping trips. I love this product and highly recommend it over using other, more scammy repellants that either don't work at all or cause other issues like making you taste bad to your partner while camping, or harming friendly bugs and animals with really harmful chemicals you/they can breathe in or get on their skin.This product doesn't have any of that. It's smokeless, silent running, light and compact. It even uses only a small amount of resources to run. One small canister of ISO gas lasted a week long trip.These pads only last about 4 hours which is fine, but make sure you keep it covered from rain. If the lads get even a small amount of rain water on them, it lowers the efficacy and run time. I had to use the product in very wet, windy and stormy environment, and it still performed well. I learned quickly what happens when the lad gets wet, and has to adjust accordingly. That was my fault, misusing the product in more austier environments, but even with the wind and rain, the mosquitoes tried to hang out with us in a swarm. It's like they did even care about the wind or rain, they just wanted to eat us as we huddled under a tarp trying to cook some of our camping food. I turned on this puppy and the mosquitoes made themselves scarce. Even with the wind and rain, the area of effect wasn't too diminished even with the pad getting some rain on it. I did have to change the pad out, but learned from the mistake. Highly recommend. I hope this helps!

These mats/pads fit in the patio model.

Heat triggers the dissipation of the mosquito repellent saturated in these mats--and seems to work well for the majority of mosquito types that go after me. Each pad tends to last 4 hours total. Sometimes, I'll switch the heat source on for an hour at a time, come back and light it again the next day, and it's still effective though the exposure to the air and elements may decrease the 4 hour total "lifespan" of the mat's repellent. The mats are easy to use, easy to swap out (on the fly), and easy to keep a stock of extras on hand.I use these with the Thermacell MR-BPR Backpacker Mosquito Repeller, which I really like and use two at a time. And I use these for at least a couple of hours every day when it's not cold outside, because the mosquitos around here are aggressive and pervasive. I like the simple setup with a propane tank to fuel the heating element.No mosquito repellant eliminates 100%, since different types of them respond to different things. But this one gets rid of most of the ones that exist where I am and go. For the few mosquitos around me that have no response to this particular repellent, I either apply a different type of repellent spray or use my handy The Executioner tennis racket zapper, which is a gratifying way to get rid of the other ones.My only complaint is that the naming of this product confused me. There must be some reason why they did this, but... These are neither 24-hour pads, nor 48-hour pads. They are 4-hour pads sold in quantities of 6 or 12. I'd prefer the package read more clearly "6-Pack of 4-Hour Pads" or "12-Pack of 4-Hour Pads" and less on the total 24-hr/48-hr time of coverage. I would also like to buy in in larger bulk, as I'd buy a 100-Pack of 4-Hour Pads" in a heartbeat.

Works pretty well. However, these types of deterrents and their burners are very much subject to winds.

we have several Thermocell systems and love them all

picked up some refills, good price, quick shipping, and I do not have to go to the store. Go Amazon.

A bit pricey but very effective. We've been using these for 4 yrs now and would never sit on the patio or deck without one being lit. They work as advertised.

These always work well. I always will buy these again.
