spider mites on Alocasia Polly
Quick answer
If your Alocasia Polly has spider mites, the most likely cause is: Alocasia Polly's thin, tender leaves with high transpiration rates create ideal microhabitats for spider mites (Tetranychus urticae). The mites colonize the leaf undersides where stomata are dense, feeding on cell sap and leaving characteristic stippling damage. Alocasia's preference for warm, dry indoor air accelerates mite reproduction cycles from 5-7 days to 3-4 days.
Start here:
- 1. Quarantine immediately upon detection—mites spread via air currents and contact
- 2. Shower leaves: Rinse undersides with lukewarm water to dislodge adults and eggs

How to reverse spider mites on Alocasia Polly
- 1
Quarantine immediately upon detection—mites spread via air currents and contact
- 2
Shower leaves: Rinse undersides with lukewarm water to dislodge adults and eggs
- 3
Apply insecticidal soap every 5-7 days for 3 treatments to break lifecycle
- 4
Introduce predatory mites (Phytoseiulus persimilis) for severe infestations—biological control
- 5
Increase humidity to 70%+ during treatment—mites cannot reproduce in moist conditions
- 6
Remove severely damaged leaves to reduce breeding sites and improve treatment efficacy
Keep spider mites off this Alocasia Polly
Maintain humidity above 60% to disrupt mite breeding; mist leaves weekly with neem oil solution (1 tsp per liter water); inspect undersides weekly using 10x loupe; isolate new plants for 14 days; increase air circulation without creating drafts.
