spider mite infestations on Alocasia Polly
Quick answer
If your Alocasia Polly has spider mite infestations, the most likely cause is: Alocasia Polly is a spider mite (Tetranychus urticae) magnet due to large, thin leaves that provide ideal feeding surfaces and shelter on undersides. Mites thrive in dry conditions below 50% humidity, reproducing rapidly on stressed plants. The combination of low indoor humidity, insufficient air circulation, and plant stress from environmental changes creates optimal mite habitat. Early signs include stippling on upper leaf surfaces and fine webbing on undersides.
Start here:
- 1. Inspect weekly using 10x magnification: Check leaf undersides, stem joints, and new growth
- 2. Quarantine immediately upon detection to prevent spread to other plants
