Can insecticide be sprayed inside a car?

Insecticide should not be sprayed as it is toxic and can harm human health. It is best to avoid using insecticide inside a car. If it must be used, apply it sparingly due to the enclosed environment. After use, ensure to open the doors for ventilation for at least one hour; otherwise, it may adversely affect health. Additionally, the composition of insecticides is complex and often contains oily substances that can adhere to the car's paint. Prolonged exposure may corrode the paint, so it's advisable to avoid using it. While it is possible to spray insecticide in a car, proper ventilation measures must be taken afterward: 1. Close the windows: Spray cockroach spray, commonly known as insecticide, into the corners of the car, then close the windows and wait for a day to eliminate the cockroaches. 2. Ensure thorough ventilation: If insecticide was sprayed the night before, make sure to ventilate the car thoroughly the next day before use. Wait until the odor has completely dissipated before entering the car. After killing the cockroaches, be sure to clean up properly.

The other day, I saw my kid spill a drink in the back seat, which attracted ants. Without thinking, I grabbed some household insecticide and sprayed it. When I rolled down the window later, the smell nearly knocked me out! The pyrethroids in the insecticide can cling to fabric seats, and the chemical residue can linger for months. The worst part was when a smoking friend got in—the aerosolized insecticide ignited upon contact with the open flame, sending sparks flying all over the rearview mirror. Now, I just use a vacuum and white vinegar to clean the interior—it’s safe, eco-friendly, and removes odors. Using chemicals in an enclosed car is like slow poisoning. I’d advise everyone not to sacrifice health for convenience.

Last week, a colleague sprayed insecticide in his car to kill cockroaches, but ended up coughing and feeling dizzy the next day. After some research, I found that using insecticide in cars poses significant risks: residues can chemically react with leather seats, accelerating aging, while plastic parts may turn white and become brittle. The propellant propane-butane in insecticides is flammable, and with summer car temperatures exceeding 40°C, there's a risk of flash explosions. Families with pregnant women should be especially cautious, as inhalation may affect fetal neural development. I taught him two practical alternatives: running the hot air conditioning for 40 minutes can kill most insect eggs, and placing a cup of lemon water on the dashboard while sun-drying the car can attract and drown insects. There are plenty of safe pest control methods available.

Just refurbished a classic car, and I absolutely won't allow anyone to spray insecticide inside. The xylene in chemical products can corrode the grain of the walnut wood trim, and the artificial suede headliner may develop yellow spots. The old car's wiring and rubber hoses can become brittle and leak electricity when exposed to insecticides. I handle pest issues with physical methods: spray a small amount of tea tree oil on the AC filter before parking—bugs hate the smell; leave a window slightly open with a silicone insect barrier clip; wipe leather seats with concentrated saltwater to remove food residue. Maintaining an old car requires the same meticulous care as antique furniture.
