Summer in the Swamp: Yellow Flies & The Heat Index

Yellow flies are a real problem on Okefenokee paddling trips once the sun starts dropping in summer — BWJ found the two things that actually work are a smoky fat-lighter fire and a hammock with an integrated bug net.

Why do we paddle in July? Because no one else does.

There is a specific kind of quiet in the Okefenokee during the summer. The tourists are gone. The day-trippers are back in the AC. It's just us, the heat, and the "Swamp Air Force"—the yellow flies.

We launched for a Fourth of July run to Round Top and Coffee Bay. The goal wasn't high mileage; it was testing our summer systems. How do you sleep when it's 90 degrees at night? How do you cook when the bugs are swarming?

The Yellow Fly RealityIf you haven't met a yellow fly, count yourself lucky. They don't bite; they chew. And once the sun starts dropping, they own the swamp.

We found two ways to beat them:

  • Smoke: We built a small, smoky fire using fat lighter. Living in the smoke is better than being eaten alive.
  • The Screen: We tested a new hammock setup with integrated bug nets. It was the only sanctuary. Tina spent the afternoon in hers, and I didn't blame her.
  • Field Kitchen Test: The Backpacking StoveThis trip was the maiden voyage for a new ultralight backpacking stove (a $30 Amazon find). I usually cook over fire or heavy cast iron, but in the summer heat, you want speed. We did a 15-bean soup with ham (frozen beforehand to act as ice in the cooler) and rice.

    The Verdict: The little burner sounds like a jet engine and boils water instantly. It scorched the beans a bit because it runs so hot, but for boiling water for coffee and rice? It's a keeper.

    The Gator CountThe summer heat brings the big reptiles up. We stopped counting after the first dozen. At one point, we had four large gators within a 50-yard radius of the boat. They aren't afraid in July. They just watch. We passed one massive bull—head size of a shovel—resting right in the middle of the canal. We gave him space, and he gave us a pass.

    The PayoffThe bugs are brutal and the heat is oppressive, but when the sun finally drops, the swamp pays you back. We had a half-moon, clear skies, and a silence you can't find anywhere else. The frogs were so loud they drowned out thought.

    It's not comfortable. But it's ours.

    Frequently Asked Questions

    How do you deal with yellow flies on a summer Okefenokee trip?

    BWJ found two methods that worked: building a smoky fire with fat lighter (living in the smoke beats being bitten), and using a hammock setup with an integrated bug net as a bite-free zone.

    Is a cheap backpacking stove worth it for river trips?

    BWJ tested a $30 ultralight backpacking stove on this trip — it boiled water almost instantly and worked well for coffee and rice, though it runs hot enough to scorch food like beans if you're not careful.

    How many alligators were seen on this summer Okefenokee trip?

    BWJ stopped counting after the first dozen; at one point four large gators were within 50 yards of the boat, including one massive bull gator resting in the middle of the canal.

    Where did this Fourth of July trip go?

    Round Top and Coffee Bay in the Okefenokee Swamp, with the goal of testing summer camping systems rather than covering long mileage.

    How do you keep food cold on a hot-weather multi-day trip without ice?

    BWJ froze the ham for a bean soup recipe ahead of time so it doubled as cooler ice, melting by the time it was needed for cooking.
