Can Insecticide Be Sprayed on the Engine Hood?
2 Answers
Insecticide can be sprayed on the engine hood. However, it is best to avoid using it because a car is a confined space, and insecticides contain numerous components with high levels of toxic gases, which dissipate slowly in such an environment and may have adverse effects on human health. Precautions for Using Insecticide: Since a car is a confined space, it is advisable to minimize the use of insecticides. After application, the doors should be opened for ventilation for at least one hour to prevent excessive odor inside the car. Inhaling too much of the fumes may cause dizziness in drivers, posing a risk to traffic safety. Hazards of Insecticide to Vehicles: Insecticides contain oily substances that can adhere to car seats and paint. Prolonged use may corrode the car's paint. Therefore, after spraying insecticide, it is essential to clean the car promptly to avoid damage. If car owners notice excessive insects in their vehicles, they should opt for a professional car wash followed by a steam treatment instead of using insecticides.
I've been driving for over a decade, and spraying insecticide on the hood is really not a good idea. Last time when I encountered mosquitoes gathering around the engine edges, I casually sprayed some insecticide, which resulted in white spots and bubbles on the paint because the solvents in the insecticide eroded the protective layer, requiring a repaint. The car's paint has a thin layer of clear coat that's very sensitive. Spraying can cause the mist to drift into the engine compartment, potentially corroding wire connectors or contaminating the air filter. Now, I use a mild car cleaner diluted with water to wipe the hood, or regularly rinse it with a high-pressure water gun to avoid chemical residues. It's even more dangerous when the engine is hot, as the spray evaporates instantly forming a mist, increasing the risk of damage. My advice is, when you notice a problem, first clean it with a soft cloth and water, and avoid using chemicals.
