Cool Thermacell Hack for Unlimited Refills

With this hack you can refill the butane cartridge unlimited number of times.

One of the main questions I have constantly received is where to buy the thermacell pads because they are still expensive but can be purchased cheaper from foreign sources. However, it takes a long time to receive them.

* I got around this problem by finding an easy way to regenerate the pads simply by using the related repellent, known as permethrin, which is in the same family as allethrin used on the genuine pads.•

Permethrin can be purchased cheaply in 16 ounce bottles containing 42% concentrate. In this more recent video, I show you how to regenerate old pads and keep reusing them:

Please note that although I have never had an adverse event with this modification, it doesn’t mean that it is completely safe. Perform this mod at your own risk. I take no responsibility for injury related to this modification.

I refill mine too. It's a good idea to mark the refilled cartridges so in the future you know that you have already removed the check valve. This keeps you from taking an already modified cartridge apart without needing to.

The 1st one I tried I boogered up the brass. Too much ham-handed pressure.
2nd, I removed o-ring and got the pliers down on the base below o-ring groove.
Success! The squeeze on the little vise-grips is key. Steady hard pull with a little rotation back & forth.
Check valve came out as shown 👍.

Thanks so much! You just saved me loads of money. I can’t believe they don’t make them refillable and sustainable

Still relevant. Screw Thermacell for going out of their way for making these cartridges not refillable.

I use the back-pack version of this appliance that uses camping gas cartridges which spares me messing around with these small plastic Thermacell cartridges.
I also don't use the Thermacell tabs because of their outrageous price. I've found that the liquid in the small bottles that some manufacturers of anti mosquito appliances use works just as well. It's easy enough to just soak the original used tabs in this liquid to regenerate them. They offer just as much protection as the original tabs. Cut up pieces of beer mats soaked in the liquid also work.

Best tutorial on this ever!!! I just did it with ease and I'm glad I won't have to pay $19.99 for refills!! Oh and Amazon has the pads for cheap!

I have a ThermaCELL that I bought 5 + years ago and I am amazed how good it works. I do a lot of wilderness camping up in Northern New England and sure glad I have this with me for it keeps the mosquitoes at bay.

Awesome. I live in the southern US and use my therma cell for hunting, fishing, and even sitting on back porch sometimes. I’ve spent loads of money on those cartridges. This will help save a lot of money. Thanks!!!!

I don't even mind the price for the repellent pads. What kills me is the butane-side of the equation. One canister should last 3 pads, 9 hrs. Invariably, to maximize pads, I tend to waste butane. Most times I simply get distracted and leave camp for longer than 3 hrs. I always wind up with more pads than canisters. This solves my issue if I can have a handful of refilled/refillable canisters. Thanks for the tips!

Excellent DIY tutorial. I've always hated splashing out good money for these things. Gonna give your method a shot.

A drop or two of super glue on the fitting before installing would lock it in, and seal against gas escaping. I would also wrap something around the fitting before pulling it our to protect against damaging the surface, and the sealing rubber " O " ring.

This is good to know I don`t how many of the Empty Cylinders I have thrown away going to try this on my next Empty one and that will be hunting season just around the corner .

These are a lifesaver in Alaska. Never have had to use deet since finding out about thermacell. They really work. At first I thought it was a gimmick but after my buddy showed me while fishing at the Deshka river one morning as mosquitoes were coming out and I grabbed for the bens and he said hold on check this out and within 5 minutes the boat was mosquito free and I ran and bought one that day. Now I own three and use them everytime we go camping. I wondered how to refill them. So much cheaper.

[countryside_hobbies]

Nice, need to try this... Some kind of environmental law should be put in place to make those refillable from factory. Wondering how much plastic waste worldwide is made because this kind of things.

[chartrucker]

Thanks for the video. I don't use the mosquito ThermaCELL but I have an old Conair cordless curls iron that I love to use on my truck. I don't do my hair often because of the exorbitant cost of the propane refills. This is going to save me a fortune and I'll look prettier too. Thanks again for the great video and hack.

[brorjordas]

Just stumbled upon his in my feed or something..
But luckily my last gas cartridge was still lying in the trash bin of my storage room. Started to do the mod right after watching the video. Worked all good. I actually did try refilling the cartridge before throwing it away. Thanks for the tip! The manufacturer has apparently put in there a seemingly unnecessary part for the whole useage of the cartridge..just to prevent user refill..
But now. More people might start now doing this mod. And the manufqcturer might start losing income from refill packages. What a bummer...😉😂😂😂

[nmartin]

I just tossed one of these in the trash earlier this week. I’ll have to dig through some kitchen waste, but I’m going to try it!

[jeepanimal]

Haven't done the bottle refill yet. But, I keep the repellant pads and spray them with more repellant, and leave till dry. They work fine.

This thing saved my life during Teal season here in south Louisiana with the mosquitoes, gnats and no see ums. Thanks for the upload, great hack.🤙🏼

I have a thermacell at my place.... wilderness....it works as described. Unbelievable.
