Starscream is prone to occur in drought or dry air, especially in dense and unventilated environment. 1. Take Jasmine to the balcony or outdoors at noon on a sunny day and spray dicofol and other acaricides. Pay attention to spray evenly on the back of leaves until gouache evaporates and then take it indoors. Spray it three times a day, and the starscream can be maintained normally without it. Spray water on the page frequently to keep enough humidity. Starscream is not easy to happen.
