Fighting aphids, fighting aphids - this is how it works!: aphids

Although the small red, black or green pests are an important source of food for other animals such as birds and ladybirds, but on the beloved plants on the windowsill, on the balcony or in the garden, they are a real pain.

Damage to aphid infestation

At the time of piercing, aphids inject their saliva into the plants. This leads to discoloration and bulges. With their proboscis, the aphids can specifically tap the pathways of the plants. This sucking action causes crippling of the shoots. In extreme cases, whole games can dry up and die off. Ripened mushrooms often settle on the excreted honeydew (sticky, viscous mass), giving the leaves a dirty appearance. Most importantly, aphids can transmit the dreaded virus plant disease. It is best to destroy the whole plant.
Aphid attack can be detected quickly and easily and treated relatively easily and efficiently. Typical for the infestation are misshapen and discolored leaves. But the point-shaped animals taste not only the foliage but also the rest of the plants: flower buds and shoot tips are true delicacies for them. Another unmistakable sign that aphids have made themselves comfortable on the plants is a sticky deposit, the so-called honeydew, which can be found on the underside of the leaves. Although this is not itself a pest, but a favorable breeding ground for the black Rußtaupilze, which can severely affect the plants.
Incidentally, the malformations of the leaves mentioned above are the result of an excretory product of the aphids. These suck namely with their trunk the carbohydrate-rich sap from the plant and excrete it later than sticky honeydew again.

Aphids - gentle but efficient

Depending on the severity of the infestation, aphids can be eliminated by different means. A chemical treatment is in most cases, and especially if you are equipped with some patience, preventable. Not a few home remedies promise good results, such as the tobacco or the Kernseifenlauge. However, all these home-made remedies have in common that they do not have their immediate effect but must be used regularly to ensure the efficient and complete elimination of aphids. Who expects a bang against the little beasts will be disappointed by home remedies rather. Their big advantages, however, are that they are mostly gentle on plants and the environment and can do without any chemical substances.

Home remedies for aphids

If the number of aphids is still manageable and the damage done to the plant is not very strong, a powerful jet of water will do wonders. A houseplant can be treated with little effort in the shower or bath with a hard jet of showerhead. But you should put them in a plastic bag that you tie well. Otherwise, the bathroom quickly becomes a battlefield.
  • If you have a garden, you can treat the infested plants quite comfortably with a garden hose. Simply adjust the water jet as hard as possible and spray the infested plants every few days - until no louse can be found.
  • Another home remedy is spraying with broth: Here, the associated herbs must soak for 24 hours, then boil and boil about 20 minutes. The broth can be made from tomato leaves and stalks, as well as from rhubarb leaves.
  • For indoor plants it is enough to immerse the whole plant in lukewarm water for 24 hours. This procedure does not survive the aphids.
  • Roses are protected from aphids by planting lavender in the interstices or sticking a clove of garlic close to each rosebush.
The classic among the aphid control products is still the soapy water. For this purpose, 50 g of curd soap are added to one liter of water and dissolved. Finally, about 75 ml of spirit is added to the solution. The result is applied to the plant using a spray bottle - but on the underside of the leaves. The mixture should not come into contact with the potting soil, so cover it well and do not expose the plant to direct sunlight after treatment.

Aphids black


If the aphid infestation is already advanced, the nettle slug is recommended as a home remedy, which can be sprayed on infested plant parts by means of a spray bottle. Again, it is necessary to repeat the application so often until the last louse has been killed. This can take a few days to weeks.
Another effective remedy for the pests is treatment with tobacco.For this purpose, cigarette tobacco or expressed cigarette butts are cooked in water until it has assumed a brownish color. After the broth has been strained, you can still add some curd soap. Once the tobacco has cooled, it is stretched with water and sprayed onto the affected parts of the plant using a spray bottle. If curd soap has been added to the broth, cover the potting soil again and avoid direct sunlight after the treatment.
In case of particularly severe infestation, a treatment with an emulsion of Niemöl (neem oil) is indicated, which is available from specialist retailers. Severely affected plant parts should be removed.

The natural enemies of the aphid

Of course, animals of the order of aphids have many natural predators. So they are a food source of various other animals. These include birds and various beetles, but also lacewings, parasitic wasps, ants and other insects. They are especially eaten by ladybugs and their larvae. A garden in which a balanced ecological balance prevails, will always accommodate enough natural predators of the aphids.
For this reason, some gardeners have developed a very proven method when they discover one or the other aphid on the leaves of their ornamental plants: they then do - nothing. Very often it happens that the little pests do no real harm and eventually disappear by themselves. Whether you want to wait and drink tea or prefer to resort to one of the above presented means, you have to decide as a hobby gardener but of course yourself.
