The control methods are as follows:

Strengthen plant quarantine: Under natural conditions, scale insects have little activity, their own spreading ability is limited, and their distribution has certain limitations. However, with the development of production, the exchange and transportation of flowers are frequent, and the opportunities for artificial and long-distance transmission of pests and diseases are increasing, which provides convenient conditions for the spread of scale insects. If pests and diseases are found, various effective measures should be taken to eliminate them to prevent further spread. ?

garlic and onions are common in our life? Heavy taste? Vegetable varieties, now we can use them to make insect repellent water!
