What is the most effective medicine for scale insects and how to completely eliminate them?

1. What medicine is most effective for scale insects?

1. Methidathion: Methidathion is a commonly used insecticide. It is not only safe but also very effective. It can remove many common insects. But there are also disadvantages. The disadvantage is that the smell is a bit strong and pungent. If you want to use it indoors, you still have to be more careful.

2. Thiamethoxam: This drug has low toxicity, will not affect human health, and has good insecticidal effects. It can be mixed with other agents to kill insects, and the effect will be better after mixing.

3. Silicone penetrant: This agent has a longer-lasting effect and can penetrate into the pores of the plant. It can assist the above two drugs and can thoroughly penetrate the eggs, thereby achieving the effect of killing the eggs. In addition to spraying, you can also use medicine to irrigate the roots, which is also very effective.

2. How to completely eliminate

If there are not many scale insects, just pinch them off with your hands or use tweezers when you find them. If there are many infected parts, the infected parts should be cut off and destroyed completely. If there is any in the soil, it is recommended to change the soil directly. However, if the insect infestation is more serious, the best way is to spray pesticides to treat it. Spraying the three drugs mentioned above in turn will produce faster results. In addition, the maintenance environment should be changed in the later stage to provide more ventilation for the plants.
