Furniture does not need to be wiped after spraying insecticides, because insecticides are biological agents, it has a certain timeliness, and after a period of time, the insecticides on the room or furniture will volatilize clean. When spraying insecticides indoors, it is necessary to pay attention to the fact that after spraying insecticides, people should leave in time and close the doors and windows, open the doors and windows for ventilation and exhaust after 30-60 minutes, and wait for the insecticides to completely volatilize before entering, so as not to cause physical discomfort.
Pesticides are chemical agents used to control pests. Including organic pesticides (organochlorine, organophosphorus, organosulfur preparations and carbamate and pyrethroids), inorganic insecticides (inorganic arsenic, inorganic fluorine, inorganic sulfur preparations), plant pesticides, mineral oil pesticides, microbial pesticides. Insecticides are the largest amount of pesticides and the most varieties of pesticides, most of which can only kill insects and cannot prevent diseases.
Insecticides play an extremely important role in increasing agricultural production and solving human food problems, but they are also the most important factors that cause pesticides to pollute the environment (such as organochlorine insecticides are chemically stable, not easy to degrade, and easy to accumulate in soil and organisms), and are also closely related to the reduction or even endangerment of natural enemies of pests and other beneficial organisms.

1. Do not wipe the furniture after spraying insecticides. Because pesticides are able to volatilize in a certain period of time. But it's best to clean it regularly.
2. The insecticide can only enter the room after six hours of spraying. Insecticides are generally in the fog state. In the process of spraying volatilization, it slowly combines with the floating matter in the air, and will not dissipate for a long time, at this time, if people breathe indoors, they will inhale the air containing insecticides, which is very bad for the body, so they can not go in immediately after spraying insecticides, because the drug residue can only be dispersed after about 6 hours.

Precautions for the use of pesticides
1. Keep away from the fire source when using, and during use, anger should be sprayed at the fire source and red hot items or placed directly next to the fire source.
Second, avoid friction static electricity when using, insecticides are flammable and explosive materials, friction or static electricity generated by sparks will also cause, it is best to stay away from or turn off the power when using, to avoid violent shaking.
3. Avoid high temperature exposure when storing, the pressure of insecticide canned gas is related to various factors such as outside temperature, the higher the temperature, the greater the air pressure in the tank, the easier it is. It should be stored in a dark place, not above 50°C, away from fire.
Fourth, do not squeeze and knock when storing, there are low boiling point solvents and propellants in the insecticide, once excessive squeezing and violent shaking and beating, the internal and external temperature differences, pressure changes, it is easy to cause accidents.
