Will scale insects die or disappear automatically when the weather gets colder?

Since scale insects are mainly active in summer, will they die or disappear automatically when the weather gets cold in winter? I thought the same thing at the beginning. There is no need to use small purple medicine to prevent the succulents raised in the open in winter. The weather is so cold that the scale insects will definitely freeze to death! When I later looked at scale insects on fruit trees, I realized that I was too naive. Many scale insects can survive the winter safely. Even if the temperature is too low, they will only reduce their activity and it is difficult to be truly frozen. Damn it, when the weather warms up in spring, they will come out again and start making meat!

A northern meat lover once conducted an experiment where he put meat with scale insects outside to freeze to see if he could freeze them to death. The result is obvious. The scale insects were frozen to death, but their fleshy flesh had long been turned into popsicles before they died, haha! So it can be seen from here that scale insects are much more resistant to freezing than succulents. It is obviously impossible for the questioner to use freezing to kill or disappear on their own! When the time comes, scale insects will crawl around on your fleshy carcass, and then laugh at your naivety! All right! This is actually what I imagined, hahaha!

However, no matter how you say it, we still cannot relax the control of scale insects in winter. The low temperature in the south is not enough to resist the invasion of succulents by scale insects, but will only slightly reduce their activity. , so the medication should be taken for prevention in time! In northern areas, succulents are kept indoors in winter, and even succulents can grow normally, let alone scale insects. Obviously, indoor heated environments in winter are also high-risk areas for scale insects, and relatively closed environments, This is more conducive to the large-scale outbreak of scale insects, so the prevention and control of scale insects in northern winter is more important than in other seasons.
