Red spiders appear on roses. Generally, there are problems in maintaining the environment. Starscream eggs can survive the winter safely. When the temperature rises in spring, it will hatch gradually. If the maintenance environment is muggy and humid at this time, it is easy to attract red spiders. Especially in summer, the breeding environment is very stuffy and the temperature is still very high, which is very suitable for red spiders to reproduce. In addition, there are many leaves of rose, so there will be insect pests p>
2、 Performance
This pest mostly appears on the back of leaves, so it is difficult to find. When it is detected, it will reproduce more. It will invade and devour the liquid in the leaves. Over time, the leaves will turn yellow, dry and, in serious cases, lose their leaves p>
3、 Prevention
After the rose is found to be infringed by the red plant, the damaged branches and leaves should be cut off in time. At this time, don't be distressed. After cutting off, it should be concentrated and burned.
