Control of aphids with home remedies: which are suitable?

Aphids are extremely unpopular with hobby gardeners – and in agriculture, pests cause enormous damage every year. Even indoor plants are not spared the pests. However, you do not have to resort to the chemicals club right away. In this article, myHOMEBOOK explains how to effectively get rid of those with home remedies.

Whether it is indoors or garden plants: aphids cause great damage. Not only do they live on the sap of the plants, they also transmit fungal diseases. If the diseases are not detected early and not treated, the plants die. However, the pests should not be controlled by chemical means. Some of these also damage garden and houseplants as well as the environment. These 7 home remedies are better for effectively controlling aphids.

Why are aphid infested plants?

The causes of an aphid infestation can vary: the plant is too dark, too hot or too dry. The result: the cell structure becomes soft and the aphids can easily penetrate the plant skin. Fertilization can also be a cause of a plant becoming sluggish – especially if it gets too much nitrogen and not enough potassium.

Rhubarb broth – home remedy for aphids

Plants can be sprayed with an undiluted rhubarb broth to prevent or ward off aphid infestations. Like three times in a row. Useful side effect: Rhubarb broth also acts as a natural foliar fertilizer. To make broth you will need:

  • 500 grams of green rhubarb leaves
  • 3 liters of water

The broth consists of crushed rhubarb leaves, which are soaked in cold stagnant water, preferably rainwater, for 24 hours. Then boil the decoction briefly and let the liquid simmer for half an hour on low heat. Allow to cool and pour through a sieve into a spray bottle.

2. Rhubarb fertilizer as a home remedy for aphids

Harmful aphid and larval infestations can be controlled extremely effectively with a corrosive, fermenting rhubarb plant fertilizer. As the name suggests, the fermented brew is quite corrosive to the pests. For rhubarb juice, use:

  • 500 grams of green rhubarb leaves
  • 3 liters of water
  • A plastic container with an air-permeable lid

And this is how you make the liquid fertilizer: Just like with the rhubarb broth, prepare liquid fertilizer brew with crushed rhubarb leaves and stagnant water or even better rainwater. After a day or two, the liquid begins to ferment.

The fermentation process can be aided by placing the fertilizer container or other non-metal container in a sunny place. The brew is stirred twice a day, the oxygen supply also promotes the fermentation. After three to four days, the manure brew is ready for use. Danger: To protect the plants, dilute the fertilizer in a ratio of 1 to 5.

What is left of liquid fertilizer can be left to ferment completely and used as foliar fertilizer. When the liquid fertilizer stops foaming after at least 14 days, the fermentation process is complete. The pre-fermented liquid rhubarb fertilizer should also be diluted in a ratio of 1 to 5 before spreading.

Tip: Fertilize morning or evening by pouring manure around the plants, but not directly on the leaves.

3. Insects that starve for aphids

Ladybirds are the largest predators for aphids. Once landed on a plant, the beetles systematically search for food. The beetle larvae are often confused with pests and destroyed. They eat 100 lice a week.

In addition to ladybugs, many other species of aphids live on aphids. Among them: hoverflies and shrews, wasps, earwigs. You can easily attract the small beneficial insects by making the garden insect friendly. You can also make an insect hotel yourself quickly and cheaply: a bundle of reeds, a pot filled with some excelsior or a piece of dead wood as shelter is enough.

4. Milk as a silver ball against aphids

7. Chestnut broth against aphids

Another home remedy for dealing with aphids is chestnut broth. Background: Chestnuts contain soapy substances, which is why they can also be used for washing. As a result, aphids can not attach to the plant and fall off. However, they are not killed directly, only the attack is dampened. In this article, you will learn how to make the chestnut broth yourself.

Other home remedies for aphids

Infested perennials, such as roses, can be rinsed off with a jet of water. You can also free the areas with your hand: Simply wipe the lice with your gloved hand.

A soap solution that you have prepared yourself is also useful. To do this, mix 20 grams of potassium chloride or soft soap in a liter of water and treat the affected plants with it. Dandruff insects hide under a wax shield, mellus are hairy. A splash of liquor in the soapy water helps here.
