    FAQS :

    What does it use to repel people? List each one.

    The answer is d-allethrin, which serves as the product's repellant.

    What chemical is being released, in my assumption, and is that safe for you to breathe?

    Answer: The most popular pesticide used in households is pyrethrin, which is poisonous and can kill cats. Pyrethrins are also known to cause low-level endocrine disruption. To term this "repellent" is inaccurate. In contrast to repelling bugs, the active substance actually kills them. You will practically be covered in a cloud of bug spray thanks to this equipment. Regarding the alarmist claims regarding the West Nile virus, the US and the majority of first-world nations just don't worry about it. The source of the sickness is people, not mosquitoes. There is no likelihood that you will contract it by being bitten if there isn't a significant outbreak where you are.

    How effective is moving around like this when hiking? Or is it intended to occupy a specific location in order to operate the 15-foot boundary?

    While trekking, it does assist, but standing still is ideal.

    What does the gray, glue-covered, half-belt clip on the back serve as? And how do you take it out?

    That's if you opt to get a holster that will fit in your belt or waistband. My so. We purchased the holster for Hunt so that it would fit on his side. The felt is there to prevent the device and belt from rubbing against each other.

    The refills cannot be used outside. Now that I need refills, why not warn about this for the product itself?

    I'm going to assume that you're talking about our Earth Scent Refills and not this particular item. Patio use is not advised for Earth Scent Refills for the simple reason that they smell like dirt (mostly used by outdoor enthusiasts to cover up personal stink).

    Has the device a battery?

    No, this item does not contain a battery. It runs on the included repelling mats and fuel cartridge.

    Is it safe to use with children inside a tent?

    Answer: I had no problems using it inside a three-person tent with my 89-year-old mother. Because the cell powers a heated element, I would advise keeping it out of the reach of youngsters. I hung mine 6–10 down from the top center of our tent. So, for an official response, contact the manufacturer.

    Is this item carcinogenic?

    No, this product is not carcinogenic. Please be aware that neither the US EPA nor the World Health Organization (WHO) have classified the active ingredient in this product, d-cis/trans allethrin, as a carcinogen. The EPA has evaluated Thermacell for outdoor safety and efficacy because safety is our top priority.

    What if I don't utilize the entire 12-hour refill at once? Do I need to start over with a new refill?

    Answer: You can start and stop the refills as frequently as you choose. Mats can be used for several sessions and last for four hours. However, if the mat has been out of the wrapper for more than a couple days, we recommend replacing it, even if it appears to still have some vitality (blue coloration).

    Refills and a dual package

    Answer: The repeller and 12 hours of refills are included in this deal.

    Does it work against gnats?

    Answer: Thermacell sells Multi Insect refills for the MR300 Portable Repeller, which has been tested to repel no-see-ums and black flies (buffalo gnats). These refills are sold separately from the MR300 portable repeller on Amazon. Description: Thermacell MR300 vs MR450
