Plants that grow in the garden have natural enemies. However, you can use beneficial insects against pests to control them.
The best-known beneficial species: the ladybug
The best example is the ladybird, which aphids taste particularly good. Now one could assume that plants growing in the greenhouse or in the winter garden do not have such pests. But of course everyone knows that this is not the case. Pests are certainly not as common here as outdoors, but plants that grow indoors are also affected by lice and the like.
Buy beneficial insects
If plants are attacked by pests, many quickly use plant protection products, although this is not necessary. Because there are beneficial insects to buy in specialist shops that you can also use indoors. These include, for example, the larvae of the seven-point ladybird (against lice), the larvae of the lacewing (also against lice) or the predatory mites (against spider mites).
It is best to get advice
If you want to use beneficials to control pests, then you must ensure that the right temperatures and the right humidity prevail so that the beneficials can hatch and become active. The professional gardener can give you more detailed information.
