Thrips in Plants: Prevention, Symptoms, and Control
What are Thrips?
Thrips are small, slender insects that can infest houseplants and damage them by feeding on the plant’s tissues.
They are most commonly found on the undersides of leaves and on new growth.Thrips are difficult to control because they are small and can hide in tight spaces on the plant. They can also reproduce quickly, so it’s important to take action as soon as you notice an infestation.
Thrips can cause a variety of symptoms in houseplants, including:
- Stunted growth: Thrips can damage plant tissues, which can lead to stunted growth.
- Distorted or curled leaves: Thrips can cause leaves to become distorted or curl up, especially on new growth.
- Mottled or discolored foliage: Thrips can cause leaves to become mottled or discolored, with yellow or white specks or streaks on the surface.
- Black or brown spots: Thrips can cause black or brown spots to appear on the plant’s leaves, stems, or flowers.
- Tiny black or brown insects: You may see tiny black or brown insects on the undersides of the leaves or on new growth. These are the thrips themselves.
If you notice any of these symptoms on your houseplants, it’s a good idea to check for thrips and take action to control them as soon as possible to prevent further damage to your plants.
To control thrips on your houseplants, you can try the following:
- Remove and dispose of infested plant parts: If you see thrips on your plant, remove and discard any infested leaves or stems to help reduce the population.
