- These home remedies for aphids are ineffective
Aphids make life difficult for many gardeners every year, because they are one of the most common plant pests. Within a short time, the yellow, green, reddish or black insects can grow into huge colonies and damage with their stinging-sucking mouthparts the leaves and young shoot tips of many plants. In addition, aphids often transmit dangerous pathogens while suckling - especially viruses. Therefore, you should not take an attack especially on fruit trees on the light side.
But you do not need to resort to the "chemical club" right away. There are many inexpensive and organically produced home remedies that have proven to fight aphids. If individual plants are infected, it is often enough to spray the pests with a sharp stream of water or wipe them off with your fingers. Since flightless aphids are not very mobile, the chance of re-infestation is very low.
In case of increased infestation, home-made broths, jays and teas from various wild plants, which are particularly rich in certain minerals, are particularly suitable. Used regularly, they not only act against various diseases and pests, but also provide the plants with additional important minerals.
With the following home remedies you can fight aphids on your plants effectively and environmentally friendly.
The classic: core and soft soap
The most well-known home remedy in the fight against aphids, is the core or soft soap. The soap does not contain excess fat and contains no fragrances, dyes or thickeners. Natural soaps, on the other hand, contain additional substances that are harmful to some plants. Therefore, natural soaps and similar liquid soaps are not suitable for controlling aphids and other plant pests.
For an effective home remedy for aphids, dissolve 50 grams of ground soap or greasy soap in 1 liter of warm water and pour the cooled, liquid soap solution into a suitable spray bottle. Now spray the affected plants.
Tip: In case of heavy infestation with aphids, the spray can be strengthened with a little alcohol or alcohol. For the additional effect you need two teaspoons of alcohol or spirit, which are simply stirred under the soft soap solution.
Nettle liquid manure
The nettle manure is also a successful home remedy for controlling aphids. To make a nettle slurry, first harvest flowering nettles and let one kilogram of the fresh herbs ferment in about ten liters of water for one to two weeks. One liter of this manure is then diluted in ten liters of water and sprayed every 14 days on the affected plants. This home remedy helps especially with an early or middle infestation with aphids. Tip: To lessen the unpleasant odor, sprinkle a handful of rock flour into the fermenting broth.

Combat with oregano
Every hobby chef knows and uses the popular kitchen herb. But it is not only good for cooking: oregano contains many substances that are effective against aphids. The spray is easy and quick to make. You only need 100 grams of fresh oregano or alternatively 10 grams of dried oregano. Pour the leaves with boiling water like tea and let the broth soak for 15 to 20 minutes. Then remove the plant residue and dilute the broth in the ratio 3: 1 with water. Now you can deploy the remedy against the pests.
A broth of tansy can be made for autumn after-flowering. For this purpose, 500 grams of fresh or 30 grams of dried herb are soaked for 24 hours in ten liters of water. Then dilute the broth with 20 liters of water to finally bring the proven home remedy on the sick plants.
Absinthe (Artemisia absinthium) has a strong spicy aroma due to its essential oils
A wormwood tea not only helps against aphids, but also against various sucking and eating vermin. For the tea, 100 grams of fresh or ten grams of dried wormwood leaves (Artemisia absinthium) are boiled with one liter of boiling water and strained after 24 hours through a fine sieve. You can use the tea undiluted against aphids in spring and summer.

Dilute two liters of manure with ten liters of water and pour or spray your plants weekly. Attention: Field horsetail manure only acts in the initial stage against aphids or as a preventive measure.
A natural remedy for reducing aphid deficiency is broth from the leaves of bracken
One kilogram of the fern leaves are mixed with ten liters of water. The broth can then be injected undiluted against aphids and is particularly suitable for indoor plants. Since bracken is very kalihaltig, the broth strengthens the plants as in the application of a fertilizer.
Onion and garlic tea
Onions and garlic are real all-rounders! The popular spices help many houseplants with a pest infestation. From 40 grams of chopped onions or garlic cloves can be together with five liters of boiling water, a helpful home remedy for aphids produce.

Here it is important that the toes are deep in the ground, so that the room is spared from the strong smell. If the plant is already infected with aphids, this method does not help anymore.
Rhubarb leaf broth

Skim milk or whey
In the case of an early discovery of aphids on tomato plants, one liter of skim milk or whey is suitable as a preventive home remedy. Diluted with four liters of water, the mixture is applied weekly to the plants. In case of heavy infestation, this method is not suitable as a sufficient control agent.
Also black tea helps against an attack with aphids. To use tea as a home remedy for aphids, pour two teabags of black tea with one liter of boiling water. The tea should last at least 15 minutes. Put the cooled tea in a spray bottle and spray the plants from all sides.
Tobacco Broth: Effective, but forbidden
An old, very effective home remedy is tobacco broth. In the past, 50 grams of tobacco were boiled with about one liter of water and the remaining tobacco was then strained with a cloth. The cooled broth was then sprayed on the infested leaves and young shoots. The contained nicotine is a very strong neurotoxin and reliably kills aphids. Since the 1970s, however, the use of purchased and self-produced nicotine-containing preparations as insecticides in home gardens has been banned.
These home remedies for aphids are ineffective
In contrast to wormwood tea, a wormwood manure does not kill the pests, but simply confuses the animals with its strong and pungent odor. Also, vinegar does not kill aphids directly, but prevents infestation only because the parasites shy away from acid. In addition, one must be very careful with the dosage, because the strong acid attacks at too high a concentration and the leaves. Broths from comfrey or stinging nettles are often advertised on the Internet against pests. However, such home remedies are pure plant tonic and do not serve to combat existing pests.
