Rescue playbook
How to get rid of thrips on houseplants
Silvery streaks and scarred new growth? Here’s a calm, day-by-day rescue plan for indoor plants.
Silvery streaks and tiny slender insects often mean thrips. Isolate, rinse, and repeat contact sprays — they hide in buds and leaf folds.
What to look for
- Silvery or bleached streaks and stippling on leaves
- Tiny slender insects (pale, yellow, or dark) that jump or fly when disturbed
- Black pepper-like droppings on leaf surfaces
- Scarred, distorted, or dropping new growth and flower buds
Day-by-day plan
Day 0
Isolate and rinse thoroughly
Move the plant away from others. Rinse foliage, stems, and leaf undersides in a sink or shower to knock off adults and larvae.
Day 0
First contact spray
Spray insecticidal soap or a labeled indoor thrips spray until leaves are wet, especially undersides, leaf folds, and growing tips.
Safety: Spot-test a leaf first. Keep pets away until foliage is dry. Follow the product label indoors.
Day 3
Repeat spray for hatchlings
Spray again every 3–4 days. Thrips eggs and hidden nymphs often reappear after the first pass — consistency matters more than a stronger mix.
Day 10
Check new growth and neighbors
Inspect with a bright light or phone flashlight. If scarring continues, keep weekly sprays for another 1–2 weeks and check nearby plants.
Safety
Thrips spread easily indoors — wash hands, isolate until clear, and avoid moving treated plants next to healthy ones. Don’t use restricted outdoor pesticides indoors.
See a nursery if…
Most new growth is deformed, the plant keeps declining after two weeks of treatment, or you can’t tell thrips from another pest.
