Scale insects are generally distributed on the back of leaves of succulents first, and will reach the center of plants after flooding. The feature is that you can catch them and crush them, as well as juice. Scale insects are undoubtedly the most annoying creatures for fleshy people. Without them, they are used to their existence when they are fleshy. But for beginners who raise succulents, they can't stand it. Why are there scale insects in my succulents? Why do they plant scale insects?

Early spring and summer are the high incidence periods of scale insects. 90% of scale insects are caused by scale insects or eggs in the branches, roots and soil of succulents you bought, but you didn't find them until they exploded into a large scale. Scale insects usually lay eggs in two places, one on succulent branches and leaves and the other in root soil. Their eggs are so small that it is difficult for you to check them clearly with the naked eye. I was meaty and had no scale insects. Is it because I'm exposed now? Open culture certainly increases the source of infection, but it is unlikely that eggs and larvae will be blown to your fleshy body from other places. Scale insects basically walk by crawling, unlike aphids who fly to find more meat, but they don't have to worry too much about the outbreak of scale insects caused by open farming. On the contrary, the indoor ventilation is poor, and once there is a source of insects, scale insects are more likely to break out.

Tools for killing scale insects: After dipping the oil painting pen in 75% alcohol, brush off 75% alcohol in the concentrated parts of scale insects for many times, which has the function of surface sterilization and disinfection. After treatment, the main components volatilize quickly, the skin remains less, and it is not easy to form spots that affect the beauty of plants. However, the oil painting pen can flexibly and effectively brush off the crust, folds, thin base, back of leaves and overlapping parts of two leaves of cactus and succulents. If you want to further clean up scale insects, you still need to use pesticides. Soak the brushed plants in 1000 times diluted 40% quick-killing EC for a while, then dry them, and place them separately when changing pots. Generally, pots replaced by scale worm eggs in soil will be cleaned and disinfected at high temperature or soaked in 0.05% potassium permanganate diluent to prevent secondary transmission. During the period, strengthen management and pay attention to the recurrence of scale insect harm.
