PlantPalSilvery streaks: check for thrips
Look for narrow moving insects and tiny black specks on new leaves or in flowers.
What to check first
Unfold a damaged young leaf gently or tap a flower over white paper. Silvery scarring, small black droppings and slender moving insects together are better clues than silver marks alone.
What to do now
Separate the plant and inspect its neighbors. Rinse foliage that tolerates washing. Sticky cards can help detect flying adults, but they do not reach insects hidden in leaves or flowers.
What to watch next
Watch the newest leaves for fresh streaks or distortion. If damage continues, confirm the pest before choosing a treatment for that plant.
