Can you take food in after spraying insecticide and ventilating for 20 minutes?

There are many factors to consider when ventilating after the use of insecticidal aerosols.

The size of the room.

The amount of active ingredient in the insecticidal aerosol (varies greatly from brand to brand).

The relative flow rate of air per unit of time.

So the vast majority of insecticidal aerosols have fragrances added to them.

One is to smell good.

The second is to allow users to sense the concentration of indoor pesticides through the concentration of fragrance.

So. After using insecticidal aerosols, ventilation should be carried out until the smell of insecticidal aerosols cannot be smelled or the odor of insecticidal aerosols is weak.
