How to fight aphids on house plants at home

When growing flowers in an apartment, you may find that they look ugly and have stopped growing. It is necessary to determine the cause and begin treatment appropriate to each specific case. A parasite such as aphids is often found on indoor plants. To successfully combat it, you need to know the available methods, and it is best to carry out preventive measures and create conditions that will prevent the appearance and reproduction of the pest.

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.

The first signs of aphid infestation:

1. The shoots curl and wither. Young specimens of domestic flowers suffer.
2. The presence of black marks on the leaves. Aphids spread sooty fungus, which appears as dark spots.
3. Clusters of insects are noticeable on the underside of the leaves.
4. Opened flower buds look ugly.
5. 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.

Varieties found on flowers

Indoor aphids are polyphagous, attacking all plants except palm trees. The shape of the jelly-like body of insects can be oval, round, or elongated. Size – up to 3 millimeters. The head has eyes, antennae, and a proboscis. Three pairs of long legs allow the insects to walk and jump. Females come with wings and without wings. Males fly.

Aphids form colonies covering the lower parts of leaves, young shoots and flower stems. She prefers plant juices rich in carbohydrates and amino acids, which is typical for well-fertilized soil mixtures. The optimal condition for reproduction is moist and warm air.

The waste product of pests is a sweet sticky secretion. A fungal infection develops in these secretions. A weakened plant is affected by viruses and bacteria. Ants spread aphids due to their syrup.

Black aphid

Black aphid (indoor) affects all types of plantings. Body length – up to 1.5 millimeters. In a short period of time, the sprout withers, dries up and dies.

White aphid

Mealybug or hairy aphid. The oval light brown bristly body is covered with a white coating. House shoots affected by scale insects look as if they are covered with frost. The stems become bent, the foliage and buds fall off.

Beet aphid

An insect up to 3 millimeters long, green/brown/black with a waxy coating. Plants affected by beet aphids stop growing, curl, dry out, and may die.

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:

1. Purchase of an infected plant.
2. Migration of parasites from the street on clothing or household items.
3. Aphids enter from the street through open windows.
4. Sticking of insects when airing flowers outdoors.
5. 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.

Additional tips and tricks

Fighting aphids is a simple process. But the procedure for exterminating pests must follow certain rules:

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.

Mechanical method

The mechanical method of cleaning a bush is effective only if there are very few harmful insects on it. To do this, you need to trim off all the affected parts of the flower if possible, and you should also give it a daily shower until the aphids completely disappear.

The most effective would be a shower using laundry soap, because this pest does not like it at all. It's important to do everything right. First, prepare a soap solution by combining water and soap in a ratio of 6:1. To protect your hands, wear rubber gloves. Moisten a piece of cloth in a soapy solution and wipe the affected buds, shoots and foliage with it, trying to remove all insects. After this, the bush is washed under running water. If necessary, this procedure can be carried out regularly until there are no pests left on the flower. However, make sure that the soap solution does not get into the substrate. During processing, remember that aphid larvae are often found in hard-to-reach places, so you must inspect every leaf and bud, while cutting off and destroying those that have the pest.

Treatment with medical alcohol is also a mechanical method. It cannot damage the sheet plates because it evaporates almost immediately after application.
