ThermaCELL works with an all-natural formula that’s made from chrysanthemum plants, which are known to keep certain bugs at bay. That repellent is soaked into a mat, and it’s released when the little butane cartridges inside heat up. All this happens without electricity, too, so there’s no need to plug it in.
One repellent mat lasts about four hours, and the butane cartridges last 12 hours so you can just keep replacing the butane cartridge and mat when you run out.
It’s much easier to enjoy a day out in the porch, yard, or at a campsite when you don’t have to worry about anything bugging you.
