Aphids on houseplants – how to get rid of them
Aphids are among the most common pests on houseplants. These small insects, usually green, black, white or sometimes red, feed on the sap of young shoots and leaves. They often appear in clusters, especially on the tips of plants or the underside of leaves. Although tiny, they can cause significant damage. Fortunately, there are several simple and natural ways to control them effectively.
How to recognise aphids
- Small, rounded insects in various colours (green, black, white, red).
- Gather mainly on young shoots, flower buds and the underside of leaves.
- Leaves may turn yellow, curl or become deformed.
- A sticky substance (honeydew) forms on leaves, which can attract mould.
- Ants are suddenly interested in the plant – they feed on the honeydew.
Why are aphids a problem?
Aphids drain nutrients from the plant, weakening it and affecting growth and flowering. The honeydew they leave behind makes leaves sticky and prone to mould, and repeated infestations can compromise the long-term health of the plant.
What can you do against aphids?
- Rinse the plant: wash the plant under the shower or sink with a gentle spray of water to remove most of the aphids.
- Mild soap solution: spray a mix of lukewarm water and soft soap (or mild dish soap) on the leaves, including the underside.
- Natural remedies: neem oil as a biological treatment, or water with a few drops of alcohol lightly sprayed on the affected areas.
- Remove affected parts: cut off severely infested leaves or shoots to protect the rest of the plant.
- Prevention: keep the plant healthy with enough light, balanced watering and regular cleaning of the leaves to remove dust and pests.
Conclusion
Aphids may seem like a serious issue, but with gentle, natural methods you can keep them under control. With proper care, your houseplants will stay strong, with healthy leaves and free from pests.
