Best Carnivorous Plants for Catching Fruit Flies on a Sunny Windowsill

Small Sundews Make Excellent Fruit‑Fly Traps

For a south‑facing window in USDA zone 5, the easiest fruit‑fly catchers are tropical sundews that thrive in bright indoor light.

Top Picks

• Drosera capensis (Cape sundew) – vigorous, dew‑covered leaves catch dozens of flies daily.
• Drosera binata (Fork‑leaf sundew) – upright, branching leaves; very decorative.

Care Basics

• Pure water (RO, distilled, rain) in a shallow tray.
• Bright light—at least 4–6 hours direct sun or strong grow lights.
• No fertilizer needed; insects provide nutrients.

Both species are perennial, easy to propagate, and tolerant of typical indoor humidity.
