What is the method of disinfection and disinfestation indoors?

Disinfection and insecticidal are two different concepts. The former is aimed at killing pathogenic microorganisms, while the latter is aimed at harmful insects. If disinfection is needed, 75% medical alcohol can be poured into the watering can and sprayed on the sofa. If you need to kill insects, you can use insecticidal aerosol. After treatment, put the sofa in a well-ventilated place until the smell of alcohol or drugs is exhausted.
