Scale insects are the most common pests, which adsorb on the leaves of succulent plants to absorb the juice of succulent plants. Fortunately, the naked eye can see them. They are white. If you find them, you can use tweezers to crack them one by one, and then spray them with medicine to completely remove them.
Alcohol can evaporate the water in the body of insects, destroy the body of pests and cause them to die. However, it should be noted that if you want alcohol to achieve the effect of insecticidal, its alcohol concentration is very important, too high bottom is not good, and the best concentration is about 75% to achieve the effect of insecticidal
If it is found that the succulent plants have very small white eggs, it is better to replace 3 cm of the soil with new soil, so that most of the pests are eliminated and the growth of pests is reduced. It should be noted that a layer of white lime is sprinkled on the surface of the new soil after replacement, which can completely eliminate the reproduction and survival of pests.
Put the whole pot of succulent plants into the water, and the water level can not exceed the flowerpot at most. Put it for 10 minutes, which is enough to kill the pests, but this 10 minutes is not a big problem for succulent plants. But pay special attention, the succulent plant that takes out from the water must be put in the well ventilated place.
Dig out or cut off the area eroded by insects, and then use insecticide. But it should be noted that the succulent plants sprayed with insecticides should be exposed to the sun for a few days. When spraying drugs, try not to spray drugs on other objects. So as not to deal with the trouble.
Fleshy raw insects are probably caused by daily carelessness in cleaning basin soil, so remember to pay attention to cleaning!
