Insecticide aerosol can also be sprayed in a pregnant woman's room, but she needs to leave the room promptly after spraying. When she intends to re-enter, she should first open the windows for ventilation for more than an hour and ensure the room is well-ventilated before entering. Pregnant women belong to a special group, and blind exposure to harmful substances may affect the fetus. Insecticide aerosol is a type of low-toxicity aerosol, mainly composed of pyrethroids, ether, and other harmful substances. Prolonged exposure to insecticides can have a significant impact on pregnant women, and the harmful substances can enter the bloodstream through their respiratory tract, potentially affecting the fetal growth and development. Therefore, it is not recommended for pregnant women to use insecticide aerosol. If insecticide aerosol is sprayed in a pregnant woman's room, she should leave the room promptly. When she needs to enter, she should first ask a family member to enter the room and open the windows for ventilation. After a period of ventilation to allow the gas to dissipate, she can then enter the room. However, attention should still be paid to keeping the room well-ventilated to minimize the adverse effects on the pregnant woman.
