Ladybugs

The main assistants of all gardeners are ladybugs and their larvae. Belong to the order of beetles or beetles, they are natural enemies of aphids and are able to eat its colonies from spring to late autumn. The daily diet of one individual consists of approximately 50 aphids.

Able to swallow from 70 to 100 adult aphid flies and their larvae per day.

In nature, ladybugs live along with the aphid colony on which they feed. To get rid of the pest in greenhouses, special technologies are used using larvae and adults of a ladybug, and various methods of attracting beetles are effective in protecting indoor plants.

Lacewing

Insects with transparent wings, light green in color, having large, golden eyes with a tint. The laceworm larvae reach one and a half centimeters long, have a warty body with sparse hairs.

Females lay eggs next to aphid colonies, and sometimes directly in them. Adults prefer to eat plants. But the laceworm larvae are predators, eating aphids, its larvae. They kill other pests of fruit crops. The time of activity of these predators is night.

The lacewing provides invaluable assistance in the battle against aphids, it is recommended that specialists fly this fly in sections or in greenhouses, if it was not previously seen.

When attracting an insect, it is advised to use tansy and caraway seeds.

Sand wasp

Adult individuals of sandy or "digging" wasps feed on flower nectar, plant sap, and sweet aphid secretions. Taking care of the offspring, these insects build nests and store food for their larvae, which include aphids, its eggs, larvae, as well as spiders, flies, caterpillars, butterflies and others.

Crickets

The so-called repeller plants are also enemies of aphids. they emit strong volatile, whose smell is not liked by most pests. Aphids do not tolerate plants with a sharp aroma and therefore migrate. Repellers are usually planted between beds, around the perimeter of fences or small islands. These include:
