How do I get rid of common houseplant pests?
Separate the affected plant from other houseplants, and wash or wipe off its leaves. Apply an insecticide that is labeled for indoor use, like insecticidal soap, and reapply it according to the instructions on the label. Inspect neighboring plants, as pests easily migrate. Prune heavily infested leaves and increase air circulation. Do not use more aggressive chemicals or attempt additional applications simply because the initial one failed.
How do you get rid of houseplant pests?
Move the infected plant away from the rest of your houseplants first. Some common insects that might be causing your plant trouble are fungus gnats, spider mites, aphids, mealybugs, or scale. You should inspect the stems, the bottom of the leaves, new growth, and the soil surface to see where the damage is most severe.
If you have a light infestation, wipe the leaves and stems with a moistened cloth or spray the plant down with lukewarm water. Remove the individual mealybugs or scales with a cotton swab. Set the plant in a location with air circulation and let it dry off.
Insecticidal soap, or a product labeled for indoor use, can be effective against soft-bodied insects. Follow the label directions for contact time and frequency of application. You may need to apply the product multiple times since some eggs or insects hidden on the plant may have been missed during the first application. Test on a small portion of the plant if the leaves are sensitive.
Preventing the pests from returning
- Look at new plants before bringing them indoors.
- Allow the new plants to remain isolated for a brief time.
- Eliminate dead foliage and any leftover plant material.
- Avoid keeping the soil constantly wet, because fungus gnats will love it.
- Allow adequate space between plants for air circulation.
Do not spray household cleaners, pure alcohol, or whatever chemical you have lying around in the garden onto the leaves. Not only will it burn the plant, but it might not be safe to use inside. If the infestation is really bad, it might be best to remove the plant to avoid infecting the others.
