What’s Bugging You? A Trail Guide to Surviving Gnats in the Smokies

Let’s talk about that special kind of madness that only a swarm of gnats can bring. You know the feeling—when they hover in clouds around your face, dive-bomb your eyeballs, and somehow find their way up your nose. These days on the high ridges of the Smokies, the gnats are out in full force—and they’re not messing around.

Thanks to an abundance of spring rain, this year’s gnat crop is booming. While they aren’t painful like other bitey things, their sheer persistence makes them one of the most annoying creatures you’ll encounter on trail.

Permethrin-treated clothing works wonders for deterring ticks and chiggers, but unfortunately, it does nothing to stop gnats from swarming your face, ears, or any exposed skin. And while their tenacity tends to fade as the sun sets over the mountainside, they return with a vengeance by mid-morning.

Here are a few trail-tested ways to reclaim your sanity:

1. Head Nets Are Your Best Friend (Most of the Time)
A lightweight head net is one of the best defenses, in my opinion. It’s breathable, effective, and saves you from the nonstop swatting. Just be ready to fumble with it when you want to eat or drink—then it’s a full-on race to return the claustrophobia-inducing shield with its elastic band snug back around your neck.

2. Manual Fans Work (But You’ll Earn That Breeze)
I carry a small, round, fold-up fan. It weighs hardly anything, and it works really well, although it does require constant manual effort. But a cool, bug-free breeze on demand is hard to beat.

3. Choose Your Insect-Repellent Carefully
Some bug sprays work okay on gnats, but many leave a sticky, smelly residue that feels grimy—especially when paired with high humidity. Worse, those heavy scents can attract more than just bugs…

A Word About Smell in Bear Country

Bears have an incredible sense of smell. Even if your products aren’t food-based, anything with a strong or unusual scent—like scented lotions, deodorants, or body sprays—could pique a bear’s curiosity. That’s why it’s best to stick with unscented hygiene products, soaps, shampoos, and detergents on trail. Yes, that includes your beloved Old Spice deodorant.

At the end of the day, hiking through gnat country builds patience, presence, and gratitude for the simple moments—like when the sun dips below the ridge and the air finally goes still. Until then, suit up, spray wisely, and keep laughing through the swarm.
