How this shows up on a Ponytail palm
Hard, rounded scale on the undersides of the blades
Rows of small, hard scales sit where the veins of the ponytail palm are thickest, and the surface below them is glossy with honeydew.
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.

The blades of the ponytail palm 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: Webbing. Only mites spin fine silk at the shoot tips.
RHS · read 13 September 2026Possible causes, likeliest first for a Ponytail palm
Most likely spider mites
Ranked higher because Ponytail palm's recorded problems point this way.
- Pale stippled leaves and tiny moving dots underneath: a mite pest RHS
Why: Spider mites feed on individual leaf cells, and each emptied cell shows as a pale speck.
What to try:
- Move the ponytail palm 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 scale insects
Ranked higher because Ponytail palm's recorded problems point this way.
- Hard, rounded scale on the undersides of the blades RHS
Why: Scale insects settle in one place under a hard or waxy shell and feed on sap.
What to try:
- Move the ponytail palm 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 ponytail palm does not move.
Most likely mealybugs
Why: Mealybugs are soft insects that cover themselves in white wax, which gives the cottony look.
What to try:
- Move the ponytail palm 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.
