It depends on the situation. After spraying insecticide in the room, it is necessary to close the room for 30 minutes, open the window and ventilate after the insecticidal effect is fully exerted, and enter the room after the smell of insecticide disappears. If the ventilation is good, you can feel the wind clearly when standing in the room, and the insecticide in the room can be dissipated after 2-3 hours of ventilation. You can enter the room at this time, and then continue to ventilate for about 1 hour after entering the room. If there is no wind or poor ventilation on that day, the pesticide in the house is difficult to dissipate, and it takes about 6 hours to enter the house. The elderly, children and pregnant women need to delay entering the house
Notes for use:
1. Before spraying, all food, water and cupboards must be sealed. It is better to use them after people eat to avoid pollution. Moreover, the medicine can must be kept out of the reach of children.
2. It is better to wear long sleeved clothes and masks to prevent skin or respiratory tract poisoning.
3. Do not overdose. Many people increase the dosage in order to enhance the insecticidal effect, but this also tends to lead to poisoning. If family members or children are found to have dizziness, nausea, blurred vision, skin tingling and other symptoms, they should leave the environment where pesticides have been used in time, and if serious, they should be sent to the hospital in time for treatment.
4. Since insecticide aerosol belongs to pressure packaging, it is necessary to avoid violent impact and high temperature environment. In addition, some products use flammable organic substances as solvents. Do not spray them against the ignition source to avoid danger.
