There are many reasons why scale insects appear repeatedly in fleshy meat. The first is that the maintenance environment is not well ventilated. No matter what kind of meat it is, it needs to be kept in a well-ventilated environment, otherwise it is not only easy to breed scale insects, but also easy to be infected with various germs, so the subjects must put their meat in a particularly well-ventilated place. If it is an indoor environment, you must always open the window to ventilate and let the air circulate as much as possible, which can not only reduce the chance of common succulents being infected with scale insects, but also avoid succulents being repeatedly infected with scale insects.
Secondly, the scale insects have not been thoroughly cleaned up. Scale insects not only move on fleshy leaves and stems, but also move on the roots near the soil surface and even lay eggs in the soil. More importantly, they breed very fast. 1 The population of scale insects can reach tens of thousands in 1 year, and scale insects are active in spring, summer and autumn (indoor heating in winter).
In addition, there may be insect sources around. If there are flowers and trees around and there are scale insects on them, it will be difficult to clean them because they can fly. As long as the source of the bug is always there, you will always be troubled by scale insects. I have a friend who has powdery mildew on the tree around her flesh, which caused her flesh infection and has never been cured. This truth is the same as the origin of scale insects.
