Insect infestation in a residential area in Changsha. What do you think can be done to clean it up?

I saw the news of insect infestation in a community in Changsha. The article talks about "inchworm", that is, the larva of foot moth. If there are bugs in the whole community as reported in the news, you can only call the relevant departments to spray pesticides. But if there are bugs in potted plants like ours, I can recommend two methods:

First, physical pest control

There is a big scale insect in my potted plant. I found some information on the internet, such as vinegar bubble, washing powder bubble, garlic juice spray and so on. These are unreliable and some will hurt plants. Later, I found that the greening of the downstairs of our community, although planting a lot of flowers and plants is more expensive than my home, and watering water is much more than our home, but there is no insect disaster. This has to be said that this is the credit of nature, and the ultraviolet rays of the sun protect plants to the greatest extent. Of course, although it can't kill bugs, it won't cause pests. So I sprayed it with household pesticides first, then put the plants in the big sun and "served" them with strong light. If there are varieties that are afraid of sun exposure, buying a sunscreen net online can also solve the demand of being afraid of sun exposure and ultraviolet rays. Since then, the plants in my family have rarely caused insect disasters. ......

Second, spray household pesticides.

To sum up, physical disinfection can only be used for prevention, and spraying household pesticides can control the present situation. As for the types of pesticides commonly used at home, they are Beijing-made flower protection drugs and Japanese Baiyao purple drugs. I have used it, and I feel better about protecting flowers. Although it still stinks, compared with the rotten cabbage smell, carcinogenicity and high efficiency of Xiaobaiyao, the flower protector is already a special pesticide. However, it should be noted that if it is to be used, it should be diluted with 500-1 000 times of water. Of course, I recommend diluting a small amount of pesticide with 1000-2000 times, then shaking it evenly, spraying it around the leaves properly, and finally closing the balcony door for ventilation. I believe that the general pests will be solved after three to five days of circulation. If it is a stubborn pest that miraculously resurrects after this period, first of all, I mind that you dig out the plants, sterilize the roots of the plants with potassium permanganate, and then replace them with professional sterile soil bought from gardening stores, or buy a bag of soil pesticides to completely disinfect the soil. After the soil is fully aired and free of insects, sprinkle a small amount of water and keep it slightly wet, then replant it and put it in a ventilated place for about a week until the plants become wet.
