If summer is the high-incidence period for red spider mites on Chinese roses, then autumn is the last狂欢 time for them, especially this year's autumn, which has been dry due to no rain.

Methods to control red spider mites on Chinese roses on the balcony
Roses on the balcony are most susceptible to red spider mites because of poor ventilation, dry, and stuffy conditions, which are very suitable for the breeding and proliferation of red spider mites.
When growing Chinese roses on the balcony, we should first do a good job of preventing red spider mites. In dry seasons like autumn and winter, remember to frequently spray water to increase air humidity or use a humidifier to humidify the air regularly. Red spider mites dislike environments with high humidity, which can significantly reduce the incidence of red spider mites.
Once detected, if the potted plants on the balcony are infected with red spider mites, it is necessary to take active measures immediately. You cannot wait until the red spider mites have grown in numbers before dealing with them, as it would be much more difficult.
It is not recommended to use too many pesticides to deal with red spider mites when growing Chinese roses on the balcony. Therefore, when using pesticides to control red spider mites, it should be done effectively the first time to avoid repeated applications.
Recommended approach:
Mix two miticides to prepare enough medicinal solution, for example, using abamectin and螺螨酯 together. Abamectin mainly kills insects, while螺螨酯 mainly kills eggs, effectively eliminating both insects and eggs, which will enhance the effectiveness against red spider mites.

First, spray the mixed solution of these two medicines on the leaf surfaces, the surface of the potting soil, the nearby floor, and other plants, and then pour the medicinal solution into a large pot or bucket.

This 360-degree, no死角 method of pest and egg control can eliminate red spider mites in one step. However, even after comprehensive pest control, it is still necessary to maintain good ventilation and increase air humidity. The main reason why red spider mites cannot be eradicated repeatedly is that the environment is suitable for their survival. It's like a rotten log infested with black fungus; even if the fungus is harvested, it will grow back if the dark and damp environment of the rotten log is not changed.
