How to kill aphids on flowers? These methods are simple and effective

Flower aphids generally refer to aphids (greenfly). To kill them, you can use a bristle brush or a soft hair brush to brush them off, or spray a wind-oil essence solution (600 times dilution) on the spots where the aphids are to kill them; alternatively, you can put 3-4 grams of washing powder into about 100 grams of clean water, stir it evenly, and then spray the solution on the flowers. Generally, spraying about 2-3 times is enough to completely kill the aphids.
