When you are using a bug spray, painting and other chemicals, it is important to make sure that there is a good ventilation in your house. Also, wear a mask, cover your skin, and wash your hand thoroughly with soap and water after using it. These toxins can be picked up by the tiny blood vessels in your lungs and carried to your liver where they will be detoxified and discharged from your body. The less you take in the better it is for your liver.
