Thrips on pothos
What's Happening
Thrips rasp pothos leaf tissue causing silvery stippling, black frass specks, and stunted growth. Their 7-14 day lifecycle with overlapping generations makes them particularly challenging. Adults fly between plants while larvae hide in soil and leaf folds. On pothos, the extensive vine structure provides numerous hiding spots. The damage appears as fine silvery streaks distinct from other pest damage.
How to Fix It
- 1
Isolate affected pothos immediately; inspect and treat all nearby plants as adults can fly
- 2
Rinse foliage thoroughly with strong water spray focusing on leaf undersides to dislodge pests
- 3
Apply insecticidal soap, neem oil, or spinosad every 5-7 days for 4-6 weeks to break the lifecycle
- 4
Use systemic insecticide (imidacloprid) for severe infestations, allowing 4-5 weeks for full effect
- 5
Deploy blue sticky traps near plants to monitor and capture flying adults
- 6
Prune heavily damaged vines to reduce population and propagate healthy tip cuttings as backup
