Can roaches survive in a hot car?

You don’t want to find roaches in your car. Fortunately, these ferocious insects can’t survive heat—however, it has to be very hot. Cockroaches can’t survive temperatures above 115°F to 120°F, according to the Institute of Agriculture and Natural Resources, Nebraska Extension in Lancaster County, it is possible to use heat to eradicate cockroaches. Thus, roaches can’t survive in a hot car.

Some studies also claim that an atmospheric temperature of about 80°F can heat your car interior to 130°F in 1 hour if you don’t have tinted windows.

Nonetheless, roaches will survive for days or even weeks at temperatures of over 120°F if they have a stable food source or if they’re hiding in areas where the temperature is not too hot.

But you don’t want to place your bet on the heat from your car killing roaches—you want to carry out a careful cleaning to get rid of them. Getting rid of roaches in a car, nonetheless, is not a walk in the park. You also need to protect yourself from contracting diseases by trying to clean their droppings and other evidence.

How to remove roaches in car

This section of the publication discusses how you can get rid of roaches in your car:

1. Identify the cause and source

If you have a roach problem, it could be a bit of your fault. Usually, minor things such as not shutting the windows properly provide the space for cockroaches to crawl inside. Roaches can grow to be quite sizeable, however, some species can still fit through small openings as narrow as 1/16 of an inch wide. This means that the slightest opening in your car window is an invitation for roaches.

In most cases, food crumbs as a result of eating in your car attract them inside. If you have children or pets, you probably have a lot of eating in the car.

And if you’re the busy type, typically always late for work or events, you’d have to eat on the way or while traveling. The leftovers, crumbs, spills, and food wrappers in the car make up the center of attraction.

Eventually, those wrappers, crumbs, and goodies accumulate, and cockroaches get to find out and get inside, especially if you park the car in a dirty area.

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?

Search the car for live roaches, fecal matter, and other visible evidence like nesting materials and food crumbs you left days back.

You could be able to perceive the odor of the fecal matter of cockroaches if the infestation is severe in the car. Inspect the glove compartment, where you keep your cup and trash, the car foot mat, backseat folds, and the doors.

2. Treat to remove roaches from the car

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

a. Vacuum the interior

This is not difficult. Get a vacuum cleaner or go to a car wash station and have the interior of your car vacuumed to rid roaches. Take out any garbage and clean out every area of the vehicle. Immediately after you do this, spray insecticides to make sure every cockroach in your car is eliminated.

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 a HEPA (high-efficiency particulate air) filter. For the time being, consider surrounding your car with bay leaves to keep cockroaches out.
