Washing powder can dissolve the cuticle of scale insects and at the same time form a layer of foam that wraps around the insect body, causing the scale insects to suffocate to death. Washing powder solution can control some pests and diseases.

Dilute to a 600-fold solution, spray once every 3 days, and after 3 consecutive sprays, all scale insects will die. After spraying the orchid plants with washing powder solution and waiting for the pests to die, the leaves must be rinsed several times with clean water.
