Aphids on mexican snowball
How do I get rid of aphids?
On mexican snowball: 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
its soft new shoots and any flower buds are what they go for, so check the growing tip rather than the mature leaves.
Drawn from this species' own record — humidity floor 20%, watering every 12–24 days, rosette 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.

Is it a pest at all?
Plenty of what looks like pest damage is a care problem. If you cannot actually find the insect described above, check the diagnosis pages for this species instead — leggy growth, root rot, leaf drop — where the causes are ranked for this plant specifically.
