Likely causes
Low Humidity
Most likelyHow to tell: The air in your home is very dry, and the needles look dusty or pale. You might see fine webbing on the stems.
What to do: Mist your plant with water daily or place it near a humidifier. Keeping the air moist makes the environment less hospitable for mites.
Infestation from Other Plants
PossibleHow to tell: You recently brought a new plant home that has mites. The pests spread quickly to your fern.
What to do: Isolate the fern from your other plants immediately. Treat the foliage with insecticidal soap or a gentle neem oil spray.
