Will spraying insecticide in a car cause an explosion?
2 Answers
Spraying insecticide in a car will not cause an explosion, but it is best to avoid using insecticide inside the car. If you must use it, do not apply too much, as the car is an enclosed space. After use, try to open the doors and ventilate for at least an hour, otherwise it may be harmful to your health. Additionally, the ingredients in insecticides are quite complex and may contain oily substances that can adhere to the car's paint. Prolonged exposure to these substances can corrode the paint, so it's best to avoid using them. You can spray insecticide in the car, but after spraying, proper ventilation measures should be taken: Close the windows: Spray cockroach spray, also known as insecticide, into the corners of the car, then close the windows and wait a day to kill the cockroaches. Fully ventilate: If you sprayed insecticide the night before, make sure to fully ventilate the car the next day before using it. Wait until the odor has completely dissipated before getting in the car. After killing the cockroaches, be sure to clean up the area.
As someone who has been working in repair shops for years, I must say spraying insecticide in a car is absolutely playing with fire. The cans are filled with flammable and explosive liquefied gases like propane and butane. Once the concentration builds up, a spark from the cigarette lighter or static electricity can cause an instant explosion. I've seen a car's roof blown off firsthand because the owner lit a cigarette after spraying insecticide inside. Even without open flames, when summer temperatures inside the car soar above 60°C, the pressurized cans can explode from heat alone. For safety, either spray in open, ventilated areas or switch to physical methods like electric mosquito swatters - never gamble with safety.
