How this shows up on a Fiddle-leaf fig
Fine pale speckling on the leaf blades, then webbing at the tips: spider mites
The leaf blades of the fiddle-leaf fig lose their shine and fill with tiny pale dots. In a heavy infestation fine webbing strings across the shoot tips.
RHS lists spider mites among the pests it may attract. Heated rooms suit them: dry, warm air speeds each generation, and the damage builds within weeks.
Telling it apart: Tap a leaf over white paper. Dots that crawl are mites; dust stays still.
RHS · read 13 September 2026Silver-flecked leaves and marked or distorted flowers: an insect pest
Silvery flecks and streaks spread over the leaf blades of the fiddle-leaf fig, peppered with tiny black dots. Flowers may open marked or misshapen.
RHS lists thrips among the pests it may attract. They feed on leaves and in flowers, and hide in buds, which makes them hard to spot.
Telling it apart: Shake a flower or leaf over white paper. Thrips show as tiny slender insects that move.
RHS · read 13 September 2026Sticky leaf blades and white fluff where they meet the stem: mealybugs
The fiddle-leaf fig carries white, cottony specks in its crevices, and growth slows. Leaves beneath the colonies turn sticky and, in time, dull or yellow.
RHS lists mealybugs among the pests it may attract. The wax keeps them dry and hard to reach, so they multiply in the sheltered joints of the vine.
Telling it apart: Wipe a tuft with a cotton swab. An insect smears or crawls; a mineral deposit or a hair does not.
RHS · read 13 September 2026Sticky leaves and immobile shell-like insects on the stems
The fiddle-leaf fig is sticky to the touch and yellows slowly. Along the veins on the undersides sit small shell-like scales that lift off with a fingernail.
RHS lists scale insects among the pests it may attract. The insect settles under a waxy shell and feeds on sap for life, so a colony builds quietly along the stems.
Telling it apart: Stickiness below the bumps. Scale drips honeydew; a leaf spot is dry.
RHS · read 13 September 2026Possible causes, likeliest first for a Fiddle-leaf fig
Most likely spider mites
Ranked higher because Fiddle-leaf fig's recorded problems point this way.
- Fine pale speckling on the leaf blades, then webbing at the tips: spider mites RHS
Why: Spider mites feed on individual leaf cells, and each emptied cell shows as a pale speck.
What to try:
- Move the fiddle-leaf fig away from other plants.
- Wash the leaves, top and underside, with a strong spray of water in a shower or sink.
What would settle it: Hold a sheet of white paper under a leaf and tap the leaf. Tiny specks that move across the paper are mites.
Most likely mealybugs
Ranked higher because Fiddle-leaf fig's recorded problems point this way.
- Sticky leaf blades and white fluff where they meet the stem: mealybugs RHS
Why: Mealybugs are soft insects that cover themselves in white wax, which gives the cottony look.
What to try:
- Move the fiddle-leaf fig away from other plants.
- Wipe off every insect you can see with a cotton swab dipped in rubbing alcohol, testing a single leaf first.
What would settle it: Touch a tuft with a cotton swab. If a small, pale, oval insect is underneath, it is a mealybug.
Most likely scale insects
Ranked higher because Fiddle-leaf fig's recorded problems point this way.
- Sticky leaves and immobile shell-like insects on the stems RHS
Why: Scale insects settle in one place under a hard or waxy shell and feed on sap.
What to try:
- Move the fiddle-leaf fig away from other plants.
- Scrape the scales off with a fingernail or a soft brush, then wipe the stems and leaves.
What would settle it: Push a bump gently with a fingernail. Scale comes away and leaves a mark; a bump that is part of the fiddle-leaf fig does not move.
