How to Get Rid of Cockroaches in the Car?

Clean the environment inside the car thoroughly, and open the windows on sunny days to allow air circulation. Apply a drop the size of a sesame seed every 10 centimeters or so, placing the pesticide in corners and crevices.

When I had cockroaches in my car, it was absolutely horrifying. I tried seven or eight methods before finally solving the problem. The key is to remove all food crumbs, even the cookie crumbs in the seams of the seats need to be vacuumed clean. I used boric acid powder mixed with flour dough and placed it near the air filter—this stuff dehydrates and kills cockroaches when they eat it. At night, I placed cockroach traps with pheromone bait on the floor mats. Also, blasting the car’s heater at maximum for half an hour is particularly effective, as high temperatures can kill insect eggs. After treatment, remember to check all the door seals—if there are cracks, seal them with tape immediately, or the roaches will find their way back in. The whole process needs to be repeated continuously for two weeks; otherwise, if the eggs hatch, all your efforts will be wasted.

Last time when I took my kids on a road trip, I found cockroaches crawling in the car, which made me so anxious that I stayed up all night researching solutions. Here are a few safe and effective methods: First, lift all the seats to clean hidden corners, especially the spare tire compartment in the trunk where cockroach egg cases are most likely to hide. Wipe the interior with water boiled from orange peels—the citrus scent repels insects without damaging leather. Pay special attention to the air conditioning system; spray food-grade diatomaceous earth powder into the vents. This natural powder destroys the wax layer on cockroaches' exoskeletons. The most crucial step is not to leave any food in the car when parked—even gum wrappers should be removed. If the situation is severe, you can try an in-car ultraviolet sterilizer; some products now come with ozone functionality, offering a very high eradication rate.

A professional exterminator with 30 years of experience tells you that eliminating cockroaches in a car requires targeting three key factors: temperature, humidity, and food sources. Last week, I helped a neighbor deal with this issue by parking the car under the scorching sun for four hours, raising the dashboard temperature to 70 degrees—more effective than insecticides. Use a syringe to inject neem tree essential oil into crevices; this plant-extracted liquid can sterilize cockroaches. Pay special attention to document holders in the glove compartment, as cockroaches love chewing on paper pulp. Finally, spray a peppermint alcohol solution into the chassis gaps to create a scent barrier. Remember not to use spray cans, as pressure changes could damage the car's electrical circuits. Repeat the process every three days, and persist for half a month to achieve a thorough eradication.

Simple and brutal three-step solution: First, starve them out! Remove all edible items from the car, including pet treats and scented cookies. Then, bake them out! Park the car on concrete at noon with windows tightly closed for three hours. The final blow is to mix boric acid with mashed potatoes into small balls and place them in spare tire grooves and seat rails. Important reminder: Never spray insecticide inside the car, as the residual odor can linger for months. If you find a cockroach nest, use a vacuum cleaner to suck them up while the heated tube kills them. Repeat the process twice a week, combined with sticky traps for monitoring, and the problem will be solved quickly.
