What are the methods for controlling scale insects on orchids?

(1) When only a few are present, use a soft toothbrush or a small brown brush to gently brush them off along the leaves, or use a thin bamboo strip to scrape the insects off.

(2) The growing environment and orchid pots should be well ventilated and let light through, and the potting soil should not be too wet.

(3) You can use 80% dichlorvos emulsion with 1000-1500 times water to make a solution and spray to kill them, 2 times, once a week.

(4) Apply 5 to 8 grams of 5% carbofuran around the potting soil, water once, and they can be killed after 7 days. (5) When the condition is found, isolate the affected plants to prevent contagion.
