What harm can aphids cause to indoor flowers?
Aphids on indoor plants are a common occurrence. The main danger of insect activity is the destruction of vegetation. Aphids pierce the skin of the leaves and suck out the juice. Colonies of parasites attack young and adult plants.
Single individuals lead to the drying out of several leaves of the flower; with timely help, the plant can be saved. A large accumulation of aphids on one indoor plant leads to its death.
Signs of pest damage
It is easy to see the presence of aphids on a plant - upon inspection, syrupy traces appearing from pest secretions and other symptoms are visible on the foliage.
Read more about why aphids appear on plants in the article here.
The first signs of aphid infestation:
- The shoots curl and wither. Young specimens of domestic flowers suffer.
- The presence of black marks on the leaves. Aphids spread sooty fungus, which appears as dark spots.
- Clusters of insects are noticeable on the underside of the leaves.
- Opened flower buds look ugly.
- Some flowers do not open.
There are several types of parasites. At the same time, the methods of combating it depend on the type of aphid. At the first signs of damage, it is necessary to immediately get rid of aphids. To do this, you need to choose the appropriate method and take preventive measures.
White
Dicotyledonous plants are most susceptible to attack by white aphids. Parasites are rare on domestic flowers. Aphids, covered with white pollen, penetrate the root system and suck out the juice. The plant dies.
Green
The parasite has a pale green color. Settles on bushes and trees. Dangerous for decorative Chinese roses, lemons, etc. Before winter, the female lays eggs near the buds. In the spring, the larvae hatch and parasitize the plant.
Black
Black aphids are dark in color and their body length reaches 5 mm. To pierce the foliage, a proboscis is located on the body of the parasite, with the help of which the insect drinks juice. Black aphids reproduce at a high rate because they do not need to mate. The larvae appear on young shoots of indoor plants and eventually move to adult specimens of vegetation.
Yellow
The yellow aphid has a corresponding color. Prefers to settle on coniferous vegetation near the buds. The primitive parasite does not spread to neighboring plants. One generation is hatched per year. Therefore, yellow aphids are few in number.

Bloody
The blood aphid is native to America. In its homeland, the insect parasitizes in the bark of elm trees. On the territory of Russia, the insect is found in gardens, rarely on domestic vegetation. The body of the parasite is covered with wool-like waxy threads.
The main signs of aphids
In order to quickly get rid of aphids, you need to detect them as quickly as possible and immediately begin to fight them. To do this, it is recommended to systematically inspect your home plants. If you are lucky enough to find aphids when there are still very few of them, then all you need to do to get rid of them is to crush the adults, as well as all the larvae. If possible, cut and destroy the affected parts of the bush. But in the case when there are a lot of pests on the plant, more effective methods will be needed to get rid of them. There are several signs by which you can understand that there are aphids on a flower:
- The plant becomes less attractive and looks sickly.
- On the surface of the above-ground part of the bush you can find very small punctures that aphids leave during their life processes.
- The surface of the stems and foliage becomes sticky from the honeydew, their color gradually changes to black, they curl up and dry out.
- The open buds become smaller and deformed; they quickly fade and fly off.
- Near the affected plant you can find ants who are trying to get their favorite treat.
Aphids can greatly harm any home flower. This pest is considered one of the main carriers of viral and fungal diseases. For example, in those areas where honeydew appears, sooty fungus forms. Aphids pose the greatest danger to indoor crops such as orchids, roses, fuchsias, hyacinths, palmaceae, hibiscus, chrysanthemums, spathiphyllums and cyclamens.
As soon as aphids are found on the plant, it should be moved away from other flowers so that the pests cannot settle in them. After this, you can begin to fight insects.
How do aphids get into the house?
The most common type of aphid found on indoor plants is the aphid. Pests are located on the roots, leaves, stems and flowers of indoor plants.
Where and why do pests appear within the apartment:
- Purchase of an infected plant.
- Migration of parasites from the street on clothing or household items.
- Aphids enter from the street through open windows.
- Sticking of insects when airing flowers outdoors.
- The vital activity of ants, for which aphids are the main source of food.
Pests practically do not move around the plant. Aphids are found everywhere on domestic flowers, regardless of the part of the crop. First, young shoots are affected, then the parasite moves to denser and stronger areas. The leaves and stems turn yellow and curl into a tube. Aphids are visible to the naked eye.
A warm and dry climate promotes active reproduction of aphids. The infected flower must be quarantined so that other crops do not become targets of aphid attack.

Aphids on indoor flowers are a common problem for indoor plant lovers. To prevent parasites from destroying crops, they must be removed in a timely manner. Regular examination of flowers will allow you not to miss important time. When the first symptoms are detected, you must immediately take measures to eliminate the insects.
Reasons for appearance
You can determine that there are aphids on indoor flowers by several signs:
- leaf curling;
- puncture marks;
- small insects with round or elongated bodies;
- growths on soft stems;
- deformed flowers;
- sticky, sweet film;
- black coating.
The color of the pest is predominantly light green and white. Flowers with delicate leaves are destroyed first. Instead of a mouth opening, the aphid has a long or short proboscis, with which it pierces the leaf cover to suck out plant sap.
The appearance of aphids is due to several reasons:
- Purchasing a flower plant with eggs of the pest, from which it spread to other house plants.
- Infection through soil during transplantation, if it has not been disinfected.
- Insemination by a winged individual during ventilation on the balcony of a house, near an open window.
- The larvae are brought into the house with soil on the fur, paws of dogs and cats.
- Purchasing bouquets of chrysanthemums or roses infected with aphids.
- The appearance of ants in the room, contributing to the formation of insect colonies.
Insects multiply exponentially every 10 days, which weakens indoor flowers or leads to death.
