Where to look for roaches in the car?

The first place you want to inspect for cockroaches is the car interior. Roaches may have migrated from your workplace or your home to your car through bags and other carriages.

If you have a roach infestation in your home, it could travel with you to the car. Cockroaches can attach to your clothing or other properties you move to the car. Even roach eggs can stick to your cloth, moving with you to the car.

What to look for?

If eliminating the roaches from your car is difficult, follow the recommendation below:

a. Vacuum the interior

b. Apply novacide

Apply Novacide to address cockroaches in your car. Novacide is a multipurpose insecticide that not only eliminates adult cockroaches but also contains an insect growth regulator (IGR) that disrupts the reproductive cycle of cockroaches, preventing the egg from hatching and developing. IGR also sterilize roaches, keeping them from laying eggs.

If you have a severe cockroach infestation, spraying Novacide in the interior of your car would be effective in eliminating the cockroaches and stopping them from multiplying.

When you want to spray Novacide, open your car doors and windows and spray the Novacide in a downward sweeping motion, making sure it gets into the seats and the flooring of the car.

Allow ventilation into the car for a while and make sure not to drive until the insecticides are completely dried and the fumes have disappeared.

c  Spray pyrid aerosol

Pyrid aerosol is another good alternative to get rid of roaches in your car if you can’t make it hot enough to discourage roaches.

When eliminating cockroaches in your car with pyrid aerosol, it removes cockroaches by acting as a flushing agent. It also helps to know the level of cockroach infestation in your car.

Pour pyrid aerosol in the spaces and edges of your car while the doors are wide open—don’t forget to spray it on the seats. Pyrid aerosol has an applicator tip you can use on cracks, holes, and crevices in the car.

After spraying, ensure to open the windows and the doors of your car to let out the fumes before you drive it. The drying process should take between 30 minutes and 1 hour to complete.

3. Prevent roaches from returning to the car

To prevent roaches from coming back to the car, you want to minimize or avoid eating in it. If you can’t do without eating in the car, make sure to frequently throw out food bags, wrappers, and leftovers before exiting. You need a vacuum cleaner in the trunk to clean up all dirt and food particles regularly.

Cockroaches will eat almost anything they find. Roaches will eat paper, cardboard, or even parts of the vehicle interior they can penetrate. Roaches don’t have teeth. However, they feature a complex structure for chewing and biting, which are separated into 3 unique parts. (1) The gizzard contains plates for grinding food in the stomach, (2) the maxilla chews food to be swallowed, and (3) the mandibles bite the food and pull it into the mouth.

Thus, roaches can eat your car owner’s manual and your vehicle ownership paperwork or go to the extent of eating specs of debris on the carpet.

Therefore, just keeping out food crumbs will not eliminate cockroaches. Your parking space needs to be cleaned up. If this is not possible, look for a different place to park your car going forward.

Finally, the idea is not just to clean your car as often as you can but also to ensure that your parking environment is clean enough. Make sure to always clean the floor, mats, and seats with a vacuum cleaner with HEPA (high-efficiency particulate air) filter. For the time being, consider surrounding your car with bay leaves to keep cockroaches out.
