spider mites on Bromeliad
Quick answer
If your Bromeliad has spider mites, the most likely cause is: Spider mites thrive on bromeliads in hot, dry conditions below 50% relative humidity — exactly the environment created by indoor heating in winter. They pierce leaf cells with their needle-like mouthparts, creating stippling (tiny yellow dots) that coalesces into generalized yellowing and bronzing. The mites are microscopic (0.3-0.5mm) and often go undetected until webbing appears between leaves, at which point the infestation is severe.
Start here:
- 1. Shower the entire plant with lukewarm water to dislodge mites and wash away webbing
- 2. Apply neem oil spray or insecticidal soap to all leaf surfaces, thoroughly covering undersides
