BEE CAREFUL. Make sure you know what you are putting in your smoker before you smoke your bees. With this day and age you must be extremely careful when adding material to your smoker. It is not recommended to use cardboard/ burlap/ old clothing ect. All of these products can have harmful carcinogens in them and you would not even know it. This Cotton Fuel and the smoker pellets fuel that I currently have listed are all natural products and are perfectly safe for your bees! Premium cotton smoker fuel. 1/2 pound Pure cotton by-products. 100% natural. Take a small handful of this cotton smoker if you’ll add it to your smoker to get a nice even clean burning smoke. A small golf ball size handful can last up to 25 minutes. Can also be used with my Kwikstart pellets Smoker Fuel Which I also have listed. Just add a wad of cotton smoker fuel add one lit Kwikstart pallet and you are good for hours worth of smoke. Don’t forget to check out all my other beekeeping equipment auctions. If you do not see it I can get it. Also if you have any questions about this item in particular or beekeeping in general please do not hesitate to message me. I will answer them as best I can. I have been beekeeping for 30+ years. Thanks again for looking and have a great day!
