Thermocell Headaches ?

Reply
Guys,
I have started to get massive headaches and I believe it to be coming from my Thermocell.
If I use my Thermocell I get headaches and never ever get them any other time.
I like to bow hunt out of a climber therefore the thermocell is typically places on my lower platform of the stand.. Yes I notice the smoke that does come up around me if there is no wind. I always understood that the smoke was harmless.. I ended my hunt 6:30 pm yesterday now 13 hours later I am still not feeling Right... Other than going back to bug spray. Any recommendations ..or has anyone else noticed this. thanks

Yesterday my thermacell was blowing in my face for a couple of hours and it seemed to be making me nauseated , and maybe a little headache , so I moved it to a lower level and it got better .

I was using a pad and gas from last years hunting season .

I love love the Thermacell but I am very cautious and only use them when I am turkey hunting and place it away from me a little ways. I am not an expert oncologist or any type of doctor but nothing good can come out of being exposed to burning insecticide in close quarters for extended periods of time.

And deer can absolutely smell it, heck I can smell it when its burning so I know they can! haha.

I have this problem too. I feel lightheaded and dizzy when I inhale thermacell fumes.

I read this thread late last week. I've never personally had a problem using the thermacell. Used mine this weekend with my 7 year old, without giving much thought to having previously read this thread. He told me that he had a headache after it had been on for 30 minutes or so. I turned it off after he told me that, and he never complained again after I turned it off.

Mine gives me a head ache trying to get it to light.

I get the same feelings using mine. I feel like my sinuses are putting pressure and causing me headaches and some discomfort. I had never had this problem before. Don't know if they changed something in their formula possibly.

Thanks guys glad to know I am not alone.. Last year I had it on and had a nest of wasp about 5 ft above me: all fell out the nest and I killed the one by one with a pocket knife or my boot. That was the first sign somethign may be stronger than I thought. The headaches were killing me: gonna have to distance myself a whole lot more..
Wearing no sent deet last sunday I took my first doe of the year with a Bow...

Seeing how many folks are reporting the headaches I got in touch with ThermaCELL to see if they had any information. I was advised that they were aware of the reports and investigating the potential issue. This thread actually was sent to them by a Google alert search. It was also stated that nothing was changed in the product. They said they would let me know any additional information comes up.

I don't doubt that some users are experiencing the symptoms. I did a Google search and saw similar reports dating back several years. I personally have used one for several years in a deer stand, duck blind and other relatively open areas. I have never experienced headaches.

The unit should not be used indoors or really confined spaces. If you're breathing it in, maybe it's too close? Some people may also be more sensitive to the chemicals used as the repellant. I'm sure anyone would get a headache if they constantly breathed in any regular insect spray.

They do work at keeping mosquitos away, but certainly are not worth any potential health risks. If you are one of the ones that gets headaches., my suggestion is to try placing it where you're not directly breathing in the fumes. If that doesn't work for you, I'd suggest you stop using it.

I have also got a little light headed from the regular thermacell pads. Once I bought a big box of the fresh earth scented pads and they were really bad, and I got a headache from them. They were on sale, now I know why.

I've been using the Thermal cell for a number of years now. Once while in a enclosed deer blind with most of the windows shut I became very sick with a bad headache and violently vomiting. I immediately opened all the windows an in less than ten minutes I was feeling fine. I don't blame the thermal cell because I should have followed the instructions and left a couple of windows open.

Come on people, and fellow hunters all products come with instructions, read them and obey by them some products go through a lot of testing to be sure of all harmless affects. The instructions are there for your benefit use them. Don't be like my wife I have a folder labeled instruction on my desktop I put personal stuff in cause she doesn't like to read instructions so she never opens it ! GOOD LUCK HUNTING AND READ ALL PRODUCT INSTRUCTIONS !

I have gotten head aches from them too, but mostly when I use them in a box stand.
