What are aphids?
Aphids, also known as plant lice, are small insects that feed on the sap of plants. They belong to the family Aphididae and there are more than 4,000 different species worldwide. Aphids range in color from green to black and can reproduce quickly, meaning a small infestation can quickly grow into a major problem.
How do aphids cause damage?
Aphids cause damage by feeding on the sap of plants. They use their sharp mouthparts to pierce the outer layer of the plant and suck out the sap. This process weakens the plant and can lead to a number of problems:
- Slowed growth: Plants attacked by aphids often grow more slowly because they receive fewer nutrients.
- Deformed leaves: The leaves may curl, yellow or distort due to the damage caused by aphids.
- Honeydew and mold: Aphids secrete a sticky substance called honeydew. This honeydew can promote mold growth, which can cause further damage to your plants.
Why are rose bushes particularly vulnerable?
Rose bushes are particularly attractive to aphids because of their soft, succulent leaves and stems. In addition, rose bushes often have a lot of new growth, which is an ideal food source for these insects. Aphids can not only reduce the aesthetic value of your rose bushes, but also affect their overall health.

Recognizing an aphid infestation is essential to take quick action. Here are some signs to look out for:
- Small insects: Look for small, oval insects on the undersides of leaves and on new shoots.
- Sticky substance: Honeydew on leaves or around the base of the plant can indicate the presence of aphids.
- Ant activity: Ants are often attracted to honeydew and can be a sign of an aphid infestation.
