The reasons for the use of empty aerosol tin cans for insecticidal water include, among others, their high level of sealing, their portability and ease of use, and their ease of spraying.

First, most of the active ingredients in insecticides are pyrethroids, which are insoluble in water but soluble in oil. The design of the aerosol can well isolate oxygen and prevent volatilization, ensuring the effectiveness of the insecticide. In addition, the propellant in the aerosol can, such as hydrocarbons, carbon dioxide, nitrous oxide, etc., is compressed in the can and the agent can be ejected by a simple press. This design makes the use of the insecticide extremely convenient.

Secondly, the sealing of the aerosol can is good, which can effectively prevent the volatilization of the agent and maintain the effectiveness of the insecticide. At the same time, due to the characteristics of convenient carrying and storage, the utility model can be used by users anytime and anywhere, especially in the crevices where pests hide, and the aerosol spraying method can effectively apply the medicine.

Finally, the aerosol cans are designed with safety in mind. The spray droplets are very small, and attention should be paid to avoid the risk of inhalation when using it, so it is recommended to wear an anti-inhalation mask when using it to ensure the safety of use.

In summary, the use of empty aerosol tin cans for insecticidal water is mainly based on its high sealing, easy to carry and use, and the convenience and safety of spraying.
