What methods are effective for controlling aphids on flowers?

For aphids on flowers, you can generally brush them off with a small brush or a soft brush, or spray a diluted 600-fold essential balm solution on the spots where the aphids are; alternatively, you can use a laundry detergent solution for control by putting 3-4 grams of laundry detergent into about 100 grams of clean water, stirring it evenly, and then spraying the solution on the flowers. Generally, spraying 2-3 times can completely kill the aphids.
