Flocks of aphids of various kinds on roses, perennials, shrubs and trees are currently tugging at the nerves of many garden owners. According to the Chamber of Agriculture of North Rhine-Westphalia, the reason for the plague is the long-lasting dryness and heat.

The annoying plant parasites prefer especially the shoot tips. Because here they can easily pierce their trunk to absorb the protein and sugary content of the plant's management system. The nutrient-rich sap contains everything that aphids need to live. But since the juice contains more sugar than the aphids themselves, they excrete the excess sweet sap immediately. For example, in no time at all, it covers garden furniture or freshly washed cars with a sticky surface. The plants are unsightly due to the aphid infestation, but they usually do not die off. Since there are plenty of young shoots, the aphids can multiply particularly strong.

Natural control of aphids

Natural antagonists of the aphids are ladybugs and hoverfly and lacewing larvae. Wherever many beneficial insects occur, the aphids are usually kept in check. In particular, the Asian ladybird, which is now native to our latitudes, is used for plastering aphids in large quantities.

According to the Chamber of Agriculture, the most important method for controlling aphids in the home garden is to create optimal habitats for beneficial insects. In a garden rich in species, the natural antagonists of the aphids are quite reliable. With low infestation, garden owners can strip off the sucking pests or rinse them off with the garden hose. Even a strong shower of rain sweeps away many aphids. Only in case of extreme mass infestation should the hobby gardener use pesticides. However, it is important to ensure that a beneficial agent and bee-harmful preparation is used, so that the beneficials are not harmed.
