Prevent aphid infestation

Host your garden with a few similar plants to avoid large-scale aphid infestation. Create a mixed culture. For example, put roses together with different bushes and fruit trees or vegetables.

Do not over-fertilize the plants with nitrogen. A too high nitrogen content also helps the aphids, since the plant sap is then particularly rich. So in full juice. Contrary to popular belief, excessive nutrients also damage the plant and it struggles to break it down. So it is damaged. Damaged plants are more likely to be attacked than a healthy organism.

Make sure that you do not destroy beneficial organisms in your garden. The aphid’s natural enemies easily eliminate smaller populations before large collections can occur. So make sure that the beneficial organisms such as ladybugs, wasps, field flies and hoverflies find enough nesting place in your garden.

In order to keep aphids away from fruit trees, gardeners recommend planting a tree disc with nasturtium. The nasturtium is said to attract insects from the fruit trees. However, there are many aphid species that will not change their host plant.

Only fertilize the soil lightly with nitrogen to prevent aphids. However, avoid over-fertilization.

You can also put lavender or other plants that have essential oils between the plant species threatened by aphids.

Savory works well against the black aphid. Put this herb at regular intervals between the endangered plant species.

In general, it is important to create mixed cultures in your garden. You should avoid larger collections of the same plants. A normal, well-balanced garden with many different types of plants in which beneficial organisms feel at home is the best protection against pests such as lice.

Support and attract beneficial insects and beneficial insects

Aphids are a popular food of many beneficial organisms. So lure these predators into your garden and naturally destroy the aphids. This is the most natural way to control and regulate aphids.

Examples are:

  • Ladybug
  • Catchy tunes
  • Parasitic wasps
  • Hoverflies
  • Lacewing

All of these animals are beneficials. They are the natural, biological weapon against aphids. In order to make their garden attractive for these beneficial organisms, they should offer them retreat and breeding opportunities. Food is also required.

Dead wood and insect hotels are particularly suitable for this.

There are also some plants that particularly attract beneficial insects.

  • Dandelion
  • Dill
  • Fennel
  • Clover
  • Deadwood

Trick aphids – Offer them alternative plants

If you want to protect the plants in your garden you can make sure that the aphids attack other plants.

You can use other types of plants so that the lice spare their proteges.

Aphids particularly like these plant species:

  • Dahlias
  • Asters
  • Nasturtium
  • Cosmeen

Prevent aphids with garlic

You can prevent aphids with garlic. You can prevent the small insects from settling on house or garden plants. Put the cloves of garlic so deep that they are just covered with soil and the smell of garlic remains in the pot. However, this method is ineffective if the plants are already infected. Aphids don’t like the smell of garlic and won’t settle on these plants.

The ear panties are also useful in the fight against lice.

The ear panties go out at night and hunt for the aphids.

Build this a shelter by hanging a flower pot the wrong way round filled with wood wool. The beetle must be able to reach the lice directly because it cannot travel long distances. It is therefore important to place the flower pot near the lice colony.

For example, install an insect hotel. As soon as the beneficial organisms have settled in their garden and feel good, they naturally start to eat the pests in their garden and thus eliminate them.

The beneficials multiply more when they get a lot to eat. However, aphids also reproduce more when they notice that they are being attacked. Aphid can „create“ up to 5 offspring a day.

Gardeners from older generations know cheap combinations of plants that support each other. Thus the threatened organism strengthens.

Beneficial agents

If there is pest infestation in the neighboring garden, you can additionally prevent them by installing beneficial nests and not removing them so that upcoming populations can also arise from these nests. Wasps are excellent aphid killers.

Old wasp nests are also used by other beneficial organisms for nesting and for raising the offspring. Be sure to leave them hanging.

However, there are also beneficial agents that use oils as the active ingredient. Cover your plants often with an oil film in the spring. This film causes the aphids to die and they don’t even start to eat. Their growth is also inhibited or stagnated by the oil. In addition, the aphids cannot reproduce. However, fruit trees and leafy plants can suffer from such an oil film.

Seven ways to prevent aphid infestation

Designing a garden close to nature – mixed cultures

Plant different types of plants in your garden. A monoculture makes it easy for aphids to adapt. For this reason, you should plant as many different types of plants in your garden. For example, plant plants with essential oils next to aphid-prone plants.

Other natural enemies of aphids: the birds

Many bird species also eat aphids. Wren and tits particularly like to eat the little pests. If you want to make your garden interesting for these bird species, place bird baths, feed and nesting boxes.

The ants and the aphids

Ants can form a kind of symbiosis with the aphids. They take care of them and even defend them against predators and other insects.

With the help of the ants, the reproduction of the aphids can hardly be stopped. The ants protect the aphids because of the honey dew. The ants benefit from the sweet sugary honeydew. They eat it and get a lot of energy in the simplest way.

You can lure the ants away from the aphids with sweet treats such as honey so that they can be fought again by their predators.

Not too much nitrogen

Under no circumstances fertilize your plants too much. Because over-fertilized plants attract aphids. The juice is then very substantial and the lice feast on it. Therefore:

Only fertilize as much as necessary.
