Some of the regular spider hideouts inside the car are the rear section of the side mirrors, air vents, under the hood, and car trunk.

Research has shown that when you start your car, the vibrations inside the car disturb the spiders.

It causes the spiders to come out of their hiding places and show up on places like steering wheel and car’s roof.

When I asked a car cleaner on how to kill the spiders hiding inside the car, his reply was quite surprising.

He didn’t mention to use any spider spray or insecticide.

He said chlorine bombs work wonders.

Car cleaners use chlorine bombs to remove stench and stains from the car’s interiors.

And they work like magic in eliminating spiders from your car.

Research conducted by Ursula Jakob, a molecular biologist of University of Michigan, showed that the chlorine bombs attacks the proteins in spiders and bugs that causes them die.

This process, known as hypochlorite, which is lethal for spiders.

To prepare the chlorine bomb, take a bowl and fill three-fourths of it with water.

Add bleach to the water. When the water turns yellow, keep the bowl inside the car.

Close all the car’s windows and keep the car windows shut.

Also ensure that you do not park your car in direct sunlight. It’ll be best to chlorinate the car under sheds or inside the garage.

There are also readily available car odor bombs containing chlorine that you can use directly.

The chlorine gas that the chlorine bomb emits kills the spiders and many other car bugs like German roaches.

And vacuum clean your car thoroughly.

Vacuum cleaning can also remove the tiny spiders and the spider eggs inside the car.

Scatter Diatomaceous Earth

Diatomaceous earth is also a spider and bug killer. Scatter it inside the car and wait for a couple of hours to do their work.

Ensure that you sprinkle generous amounts of DE in the tight gaps and spaces inside the car.

Diatomaceous earth is a desiccant, and it has sharp particles.

The particles penetrates the insects’ exoskeletons and dehydrates them from the inside by absorbing their fatty acids, moisture, and bodily fluids.

That causes the insects to die.

But it’s not an instant insect killer. You’ll need to wait for a while to let it do its work.

Diatomaceous earth will kill any baby spiders and small bugs that might be hiding inside your car.

Follow it up by vacuum cleaning the car to remove the diatomaceous earth and dead bugs.

Keep Spider Traps Inside The Car

Spider traps are sticky and reeks of smells that draw spiders.

Keep one or two of these traps inside the car in places like underneath car seats and dashboard.

You can also keep a couple of these spider traps in your car’s trunk.

Let the spider traps remain inside the car overnight.

Use a vacuum cleaner to scoop off the trapped spider and the spider trap.

Dispose of the spider along with the vacuum cleaner dust bag outside of your property.

Spider traps are a great hack to draw out a hiding spider. You can use them inside your home too.

Seal Gaps And Cracks Inside The Car

It’s vital that you prevent spiders from entering your car.

Gaps and crevices on your car are primary entry points for spiders and other bugs.

Sealing them, or using rubber stripping to close those gaps will shut those gaps and hence, deny the spiders from entering your car.

Use Peppermint Essential Oil Spray

Spiders hate the peppermint smell. And they avoid anything that smells minty.

So, take the peppermint spray and spray it inside the car, especially along the gaps that you just sealed.

Spray it on the car’s exteriors too.

The smell remains for two – three days.

So, it’ll be best to continue spraying at least twice a week to make your car smell fresh and to keep the bugs away.

Keep Your Garage And Car Clean

Regular cleaning of your garage and car and ensuring that there’s no clutter inside these places helps in keeping spiders away.

Do not let clutter build up inside your car.

Don’t eat and drink inside the car. That cause food and beverage stains inside the car which attract bugs like ants in the car.

And bugs in the car are food for spiders, so, they can draw spiders inside the car.

Also, always park your car in clean places.

Don’t park your car near organic debris like leaf litter or decaying wood piles.

Spiders lurk in these places, and they can sneak inside your car.
