How this shows up on a Parlor palm
Dull, finely mottled fronds and faint webs: spider mites
Seen side-on, the parlor palm looks dusty and bleached. Under a lens the undersides move with minute mites, and silk gathers where fronds meet the stem.
RHS lists spider mites among the pests it may attract. They feed from the underside, so the damage shows on top long before the mites are noticed.
Telling it apart: Webbing. Only mites spin fine silk at the shoot tips.
RHS · read 13 September 2026Silver-flecked leaves and marked or distorted flowers: an insect pest
The surface of the fronds of the parlor palm looks scraped and silvered, and slender insects smaller than a grain of rice run or jump when disturbed.
RHS lists thrips among the pests it may attract. They rasp the surface cells and drink the contents, which leaves the silvered, empty tissue.
Telling it apart: Whether the marks are silver. Thrips leave a sheen; sun scorch leaves dry, bleached tissue.
RHS · read 13 September 2026Slow growth and limp leaves, with white specks on the roots: root mealybugs
Nothing on the fronds explains the decline. The roots of the parlor palm carry small white waxy clusters, most thickly at the edge of the root ball.
NC State Extension lists root mealybugs among the pests it may attract. They feed on the roots out of sight, so the first sign is a plant that cannot take up water.
Telling it apart: Whether the roots are firm. Root mealybugs leave firm, pale roots with white patches; rot leaves them brown and soft.
NC State Extension · read 13 September 2026Small raised bumps along the stems and veins, with sticky fronds: scale insects
Rows of small, hard scales sit where the veins of the parlor palm are thickest, and the surface below them is glossy with honeydew.
RHS lists scale insects among the pests it may attract. Each scale sits in one place drawing sap and dripping honeydew, which is why the fronds below turn sticky.
Telling it apart: Stickiness below the bumps. Scale drips honeydew; a leaf spot is dry.

Most likely spider mites
Ranked higher because Parlor palm's recorded problems point this way.
- Dull, finely mottled fronds and faint webs: 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 parlor 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 Parlor palm's recorded problems point this way.
- Small raised bumps along the stems and veins, with sticky fronds: scale insects RHS
Why: Scale insects settle in one place under a hard or waxy shell and feed on sap.
What to try:
- Move the parlor 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 parlor 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 parlor 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.

This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
