anthurium velvet mite on Anthurium
Quick answer
If your Anthurium has anthurium velvet mite, the most likely cause is: Anthurium velvet spider mites (Brevipalpus spp.) differ from common spider mites (Tetranychus) in that they induce erythema or rust-colored discoloration on Anthurium leaves rather than the typical stippling pattern. This occurs because Brevipalpus feeds on both epidermal and mesophyll cell layers, causing cellular necrosis that manifests as raised brownish-erythematous lesions often mistaken for fungal infection or sunscald. The mites are smaller (0.2-0.3mm) than Tetranychus and produce no visible webbing, making detection with standard 10x loupe difficult without proper lighting angle.
Start here:
- 1. Confirm presence using 20x handheld microscope with oblique LED lighting—look for small (0.2mm) reddish-brown mites moving slowly across leaf undersides.
- 2. Apply abamectin (Avid 0.15 EC) at label rate for ornamentals, or spiromesifen (Forbid 4F) as alternative miticide effective against Brevipalpus.

How to reverse anthurium velvet mite on Anthurium
- 1
Confirm presence using 20x handheld microscope with oblique LED lighting—look for small (0.2mm) reddish-brown mites moving slowly across leaf undersides.
- 2
Apply abamectin (Avid 0.15 EC) at label rate for ornamentals, or spiromesifen (Forbid 4F) as alternative miticide effective against Brevipalpus.
- 3
Target undersides thoroughly as these mites rarely appear on upper leaf surfaces during feeding.
- 4
Repeat application at 14-day interval for 2 cycles—Brevipalpus has longer generation time than Tetranychus, requiring extended treatment window.
- 5
Isolate affected plants; rust-colored damage is irreversible but new growth remains healthy once mites are eliminated.
Keep anthurium velvet mite off this Anthurium
Use 20x magnification with oblique lighting to detect the characteristic rust-colored mite movement on leaf undersides; inspect new plants for faint erythematous patches before adding to collection; maintain humidity above 60% as Brevipalpus prefers moderate rather than high humidity.
