Butterwort: The Tiny Plant That Eats Gnats
Butterworts, also called Pinguicula, are compact carnivorous plants with sticky leaves that catch fungus gnats, fruit flies, and tiny flying insects.
Choose Your Butterwort First
These are small, collectible, gnat-catching plants. Pick one for your kitchen windowsill, plant shelf, or anywhere tiny flying bugs keep showing up.
RootGrowings tip: Butterwort catches adult gnats, but it does not fix the root cause if your other plants are overwatered. Let soggy plant soil dry, improve airflow, and use Butterwort as the pretty gnat-catching helper nearby.
Why Butterwort Works for Gnats
If you keep seeing tiny flies around your plants, fruit bowl, sink, or kitchen window, Butterwort is one of the most beautiful plants to try. Its leaves produce a sticky surface that traps tiny flying insects.
The best part is that it does not look like a trap. It looks like a small, soft, pretty rosette, and many varieties can also flower when they are happy.
🪰 Sticky leaves
The leaves naturally trap tiny flying insects like fungus gnats and fruit flies.
🌿 Compact size
Most Butterworts stay small, so they fit easily on windowsills, shelves, and kitchen counters.
☀️ Bright spot lover
They do best on a sunny windowsill, under T5 lights, or under LED grow lights.
💧 Moist, not flooded
Keep the medium moist, but do not drown the plant in a deep tray of water.
Which Butterwort Should You Choose?
Pinguicula moranensis
Choose a moranensis type if this is your first Butterwort. It gives you the classic gnat-catching look without feeling too rare or intimidating.
Care tip: Keep it bright and use mineral-free water. If the leaves stop looking sticky, improve the light first.
Johanna, Riva, Pirouette, or Razzberry Blonde
Choose these if you want your Butterwort to feel more decorative. Under stronger light, many colored Butterworts can show pink, blush, purple, or reddish tones.
Care tip: Increase light slowly. Strong light can improve color, but sudden harsh light can stress the plant.
Laueana, Yucca Do, ehlersiae, and Sumidero I
Choose these if you want a more collectible Butterwort with a special leaf shape, flower type, or growth habit.
Care tip: Keep the setup simple: bright light, Mexican Pinguicula mix, and gentle moisture.
Butterwort Care Guide
☀️ Light
Give Butterwort a sunny windowsill, T5 light, or LED grow light. Better light usually means stronger growth and better leaf color.
💧 Water
Use distilled, rain, or reverse osmosis water. Keep the medium moist, but avoid keeping the plant soaked all the time.
🪨 Soil
Do not use normal potting soil. Use Mexican Pinguicula mix or a nutrient-poor carnivorous plant mix.
🪰 Feeding
It can catch tiny bugs on its own. You do not need to fertilize it like a normal houseplant.
Important: Butterwort helps reduce adult gnats, but fungus gnat larvae live in wet soil. If you keep overwatering your other plants, the gnats can keep coming back.
Common Butterwort Questions
Will Butterwort remove all gnats?
It can catch adult gnats, but it is not a full infestation fix by itself. You still need to stop overwatering, improve airflow, and let affected plant soil dry properly.
Can I water Butterwort with tap water?
Use distilled, rain, or reverse osmosis water instead. Tap water minerals can build up in the soil and stress carnivorous plants over time.
Can Butterwort sit in a dark kitchen corner?
No. Butterwort needs bright light to stay healthy and sticky. If the corner is dark, move it to a bright windowsill or use a small grow light.
Should I feed it bugs?
Usually no. Indoors, it often catches tiny insects on its own. If there are no bugs, the plant can still grow with the right light and water.
