How to control red spider mites on flowers on a home balcony?

For keeping flowers at home, you can have a flower sprayer ready. In 400 ml of water, drip in 4 drops of propargite, fenvalerate or huachongjing (equivalent to a 2000-fold dilution), or drip in 8 drops of dicofol or dimethoate (equivalent to a 1000-fold dilution). After adding the pesticide, shake well and spray immediately. The spraying should be even and thorough, and special care should be taken to spray the undersides of the leaves well.
