Hello, outdoors folk! We’re here again to talk about our sponsor Thermacell® and its mosquito repellent devices!

As you probably remember—or perhaps know from personal experience—the devices create a 15’ x 15’ “mosquito protection zone” that also repels other types of flying, biting insects, like black flies and no-see-ums, while being virtually odorless and leaving none of the usual oily residue or acrid perfume of lotion and spray insect repellents. The lanterns, torches, and repellers are used by hunters, gardeners, campers, hikers, military personnel, and folks who just love hanging out on their porch, patio, or in their backyard. But we’ve hardly scratched the surface of HOW the devices work.

The EPA-approved devices have a 98 percent effectiveness rating and have been tested across the globe in swamps, tropical climates, and across the good ol’ U.S. of A. And perhaps the part that makes it so effective is that it is easy to set up and uncomplicated to operate. You simply screw in the butane cartridge and install a blue allethrin-dipped mat, turn the device switch ON, and press the START button.

Once your device is lit, the science comes in. The butane inside the device heats the grill that overlays the mosquito repellent mat. This, in turn, causes the liquid allethrin in the mat to vaporize and diffuse into the air through a process not unlike that of an aromatherapy candle—but much more helpful in the field:

Once vaporized, the allethrin is able to move freely through the air, and in less than 10 minutes, you’ll be enjoying a force field that repels mosquitos and other biting insects. It might even look this cool to your imagination:

The butane cartridge lasts for 12 hours and the repellent mat last for four hours, which is plenty of time to settle your poker game or reel a couple of fish in for dinner—or both. And since changing them out is such a breeze, if the poker game runs long, the fish aren’t biting, or you just want to enjoy the sounds of nature at dusk, twilight, midnight, or later, you’ll have the back-up you need.

Negroni, anyone?

Of course, nature is the boss whenever we step outside. and high winds are a natural deterrent to both mosquitos and the benefit of a device that repels them. When using a Thermacell product, it is best to choose an outdoor location where there is little wind or minimal air movement. When you’ve found a spot of relative calm, the Thermacell product is most effective when placed near the ground. If there is some wind where you are hoping to use the appliance or lantern, you’ll have the best results if you place it upwind of your work or relaxation space so that when the breeze comes, it brings the repellent along with it.

And if you’re like your author here, when someone tells you that a product works great, you definitely want to try it for yourself before you buy into the hype. Thermacell, like all companies that have faith in their products, offers a full refund if you find yourself dissatisfied with the results. So gear up with your Thermacell appliance and Pocket Ranger® mobile app, and get in the field!
