Surviving the Adirondack Black Fly Season

If you spend time in the Adirondacks—whether you own a vacation home or just visit—you’ll likely meet one of the region’s smallest (and most notorious) locals: black flies.

Black fly season typically runs from April through early June, peaking in spring. Their bites can be irritating, but understanding when they’re active and how to manage them makes a big difference in your comfort outdoors.

For second-home owners and visitors alike, learning this natural seasonal rhythm helps you plan your time at the lake, cabin, or camp more enjoyably.

The good news? For much of the area it’s short-lived. By early summer, black flies are mostly gone—just in time for some of the best Adirondack weather of the year.
