How to Get Rid of Thrips
Last Updated: May 2026 · Plant Care Answer
Direct Answer
Thrips are difficult because eggs can be inside plant tissue and immature stages can hide in soil. Isolate the plant, remove badly damaged leaves, rinse foliage, use yellow or blue sticky traps for adults, and repeat a labeled treatment over several weeks.
Signs of Thrips
- ->Irregular silver or bronze scarring on leaves.
- ->Tiny black dots of frass on damaged areas.
- ->Distorted new leaves or scarred flowers.
- ->Tiny slender insects that move quickly when disturbed.
Why One Treatment Rarely Works
Thrips have life stages in different places: eggs can be inserted into leaves, mobile stages feed on foliage, and later stages may hide in soil or tight crevices. A single spray misses part of the population.
Control Plan
- ->Isolate the plant immediately.
- ->Prune the worst leaves if they are heavily scarred or curled.
- ->Rinse leaves and stems, especially new growth.
- ->Add yellow or blue sticky traps to monitor adults.
- ->Use insecticidal soap, horticultural oil, or another product labeled for thrips on houseplants.
- ->Repeat according to label directions until no new damage appears.
