What is the correct way to use pesticides?

The correct way to use pesticides is to spray them directly at pests, or close the doors and windows and spray them indoors in all directions, so that the room will be covered with drug fog, mosquitoes, flies and other flying insects will die within a few minutes, and then open the doors and windows to get enough ventilation before entering the room. For reptiles such as cockroaches, it is necessary to spray aerosol evenly where they haunt, stay or inhabit.

Precautions:

First, before spraying, all food and water sources must be sealed, and the medicine should be sprayed after eating as much as possible. The medicine pot should be placed out of the reach of children.

Second, the human body should be protected. It is best to wear long-sleeved clothes and masks to prevent skin and respiratory tract poisoning.

Third, don't overuse pesticides.

4. Insecticides are pressure-packed, so be sure to avoid violent impact or high temperature storage, and don't spray at the fire source.

5. The use of pesticides has gone through several stages: natural pesticides and inorganic compounds were first discovered, but their effects were single, their dosage was large and their duration was short; Organic synthetic pesticides such as organochlorine, organophosphorus and carbamate have the characteristics of high efficiency, high residue or low residue, and many of them have high acute toxicity to mammals.
