How to get rid of thrips on houseplants
There are a number of ways to get rid of thrips on houseplants. Some of the most common methods include:
- Physical removal: You can remove thrips from your plants by hand. This is most effective when the infestation is small. To do this, carefully inspect your plants for thrips. When you find them, use a cotton swab or a piece of paper towel to wipe them away.
- Insecticidal soap: Insecticidal soap is a safe and effective way to kill thrips. To use insecticidal soap, simply mix it according to the directions on the label and spray it on your plants. Be sure to cover all of the leaves, including the undersides.
- Neem oil: Neem oil is another natural insecticide that can be used to kill thrips. To use neem oil, simply mix it according to the directions on the label and spray it on your plants. Be sure to cover all of the leaves, including the undersides.

Preventing thrips infestations
