How do I get rid of common houseplant pests?
Isolate the affected plant, rinse or wipe the leaves, and treat the pests repeatedly with a product labeled for indoor plants, such as insecticidal soap. Check nearby plants because pests spread easily. Remove badly infested leaves, improve airflow, and follow the product label. Do not use stronger chemicals or extra applications simply because the first treatment did not work.
How do you get rid of houseplant pests?
Start by moving the affected plant away from your other plants. Common pests include fungus gnats, spider mites, aphids, mealybugs, and scale. Inspect stems, leaf undersides, new growth, and the soil surface to identify where the problem is concentrated.
For a light infestation, wipe leaves and stems with a damp cloth or rinse the plant gently with lukewarm water. Cotton swabs can help remove individual mealybugs or scale. Let the foliage dry in a place with good airflow.
Insecticidal soap or another product labeled for indoor plants can be useful for soft-bodied pests. Apply it exactly as directed, including the recommended contact time and repeat schedule. These treatments often need several applications because eggs or hidden insects may survive the first one. Test the product on a small part of the plant first if the foliage is delicate.
Preventing a return
- Inspect new plants before bringing them indoors.
- Keep new arrivals separate for a short observation period.
- Remove dead leaves and plant debris.
- Avoid constantly wet soil, which can support fungus gnats.
- Give plants enough space for air movement.
Do not pour household cleaners, undiluted alcohol, or random garden chemicals onto leaves. They can burn the plant and may not be safe indoors. If an infestation is severe, removing the plant may protect the rest of your collection.
