What you see
They cluster on the soft shoot tips, with the larger part of the colony on the undersides of the leaves.
The approach is the same on any houseplant. Take the insects off by hand first, then check, then treat again as often as it takes until a check turns up nothing.
Move the plant out and rinse it off
Carry the affected plant away from the group as soon as you see the aphids. They walk from leaf to leaf where plants touch, and winged ones cross short open stretches of a room.
Then rinse the plant with lukewarm water. Tilt the pot so the water does not collect in the soil, and aim the spray upward at the leaf undersides. That is where most of the colony sits.
On soft new growth, thin leaves and open flowers the spray is too rough. Wipe the insects off with a damp cloth or a soft brush instead, rinsing the cloth as you go.
Cut out single shoot tips that are covered end to end. That removes more insects in one motion than any treatment afterward.

What to do now
Take the plant out of the group and rinse it with lukewarm water, tilting the pot. On soft growth and open flowers, wipe them off with a damp cloth and cut out shoot tips that are covered.
What home remedies can do
The common home remedy is insecticidal soap in water, sometimes with a little rubbing alcohol added. It works only where it actually wets the insects. Anything you miss while spraying survives and keeps breeding.
So spray slowly and from below, until leaf undersides, shoot tips, leaf axils and leaf stalks are evenly wet. After about an hour most plants take a rinse to get the solution back off.
Dish soap is not a substitute. It carries additives that can spot or scorch sensitive leaves. Test any solution on one leaf first and look at that leaf two days later before you spray the whole plant.
Never treat in full sun and never on a dry root ball. Water first, spray in the evening and keep the plant out of direct light for the rest of the day.
Garlic tea, nettle tea and coffee grounds turn up on a lot of lists. Indoors the first two smell strong, their effect on an established colony is weak, and coffee grounds never reach the insects on the shoots at all.
Ready-made sprays and beneficial insects
Garden centers sell sprays for houseplants based on potassium soap, canola oil or neem oil. They also work on contact and need the same complete coverage. Follow the dose on the label and the note about whether the product is meant for indoor use.
Oil-based products leave a film on the leaf. On hairy leaves, on succulents with a powdery bloom and on young growth that can cause damage, so test one leaf here too.
Beneficial insects such as lacewing larvae and parasitic wasps can be ordered for indoor use. They need several weeks and a plant that is not sprayed again in that time. In a single pot at a window they wander off easily, and in a densely planted sunroom they work more reliably.
The follow-up check decides
Aphids breed fast, and the newly hatched ones are hard to see at first. One treatment rarely catches the whole population.
Look at the same places every two or three days: shoot tips, young leaves, leaf undersides, flower stalks and leaf axils. If you find insects again, treat again the same day.
Only after two checks in a row turn up nothing does the plant go back with the others. Go through the neighboring plants over the following weeks as well.
Wipe the sticky honeydew off the leaves with a damp cloth. Black sooty mold settles on a film that sits for a while, and it shades the leaf and comes off badly.
What you see
Newly hatched aphids are hard to see. They show up again on shoot tips, young leaves, leaf undersides, flower stalks and leaf axils.
What to do now
Check the same spots every two or three days and treat again the same day you find any. The plant rejoins the others only after two checks in a row come up empty.
Where the aphids came from
The usual route is a new plant. Keep every new arrival on its own for two or three weeks and look it over regularly before it takes its place.
In summer winged aphids come in through open windows and on plants that spent the season outdoors. Go over patio plants closely before you bring them back in for fall.
Cut flowers and a fresh bunch of potted herbs bring aphids in too. Keep both away from your houseplants.
Very soft, dark green growth comes from generous nitrogen and is especially attractive to aphids. So keep liquid fertilizer at the strength on the package and no stronger.
What you see
New plants, patio plants coming back indoors, cut flowers and herb pots carry them in. Soft dark green growth after heavy feeding draws them.
What to do now
Keep every new plant on its own for two or three weeks and look it over. Check patio plants before bringing them in, keep bouquets separate, and dose liquid fertilizer no stronger than the label says.
When leaves stay damaged
Leaves that were distorted, curled or spotted by feeding do not grow smooth again. They stay that way until they drop on their own. Cut them off only if the plant keeps enough healthy foliage.
New growth tells you whether the plant is clear. If it comes in smooth and even, the treatment worked. If it comes in stunted again, insects are still sitting somewhere, and you go back over the shoot tips and leaf axils.
Whether a plant is a problem around pets or children is covered in its own care guide. If you suspect poisoning, a vet or a doctor is the right call.
What you see
Distorted, curled or spotted leaves stay that way until they fall. New growth that comes in stunted again means insects are still on the plant.
What to do now
Remove damaged leaves only while enough healthy foliage remains. If new growth is stunted, search the shoot tips and leaf axils again.

Common questions
How do I get rid of aphids on plants fast?
Set the plant on its own, cut out the shoot tips that are covered and rinse the rest from below. That takes off most of the colony in one pass. The rest come off through the follow-up checks over the next two weeks.
What home remedy gets rid of aphids on houseplants?
The simplest one is the most reliable: rinse them off with lukewarm water or wipe them off with a damp cloth. Insecticidal soap in water adds to that, but only on the spots you actually wet. Garlic or nettle tea does very little on indoor plants.
How often do I need to treat for aphids?
As often as a check still turns up insects. Look every two or three days and repeat the treatment the same day you find any. Two clear checks in a row are the signal to stop.
Are aphids harmful to houseplants?
A strong plant shrugs off a small infestation. Left alone, new shoots stay small, leaves curl and buds stop opening. The sticky honeydew also brings sooty mold onto the leaves.
Where do aphids on indoor plants come from in winter?
Usually from the store. New plants, cut flowers and potted herbs carry a few in, and they breed undisturbed in a warm, dry room. Two or three weeks of quarantine for every new plant catches that.
Do I need to change the soil if my plant has aphids?
No. Aphids live on shoots and leaves, not in the potting mix. Repotting does nothing against them and costs a weakened plant energy it needs.
