Certain mosquito repellents on the market use toxic liquids to produce toxic substances to drive mosquitoes out of the room. However, due to the continuous release of toxic vapors into the room, the air composition is naturally balanced after midnight, and physical health reaches or exceeds the critical level. Usually, these vapors pass through the lungs to produce anesthesia to mosquitoes and other organisms. Long-term exposure to toxic gases may cause nervous system related problems.
