Aphids on strawberry begonia
How do I get rid of aphids?
On strawberry begonia: Clusters of soft insects on the newest growth, with sticky honeydew. Rinse them off, pinch out the worst tip, then insecticidal soap weekly for three weeks.
Clusters of soft green, black or pink insects on the newest growth and flower buds, thickest right at the growing tip. Sticky honeydew below them, and often distorted or curled new leaves.
Why this plant gets them
it grows fast and aphids feed on soft new growth, so a fast grower offers them a continuous supply of exactly what they want.
Drawn from this species' own record — humidity floor 45%, watering every 5–10 days, spreading habit. Full care entry.
The life cycle, and why one treatment fails
Indoors they reproduce without mating and give birth to live young, so a population doubles in days from a single individual. There is no egg stage to wait out.
What actually clears them
Knock them off with a firm rinse first. Insecticidal soap weekly for three weeks handles the rest. Because they concentrate on new growth, pinching out the worst-affected tip removes a large fraction of the population in one cut.
Ladybirds indoors, which fly to the nearest window and die there. Also companion planting, which has no meaningful effect in a pot on a windowsill.
