How To Get Rid of Spiders in Your Car

Why do spiders come inside? Usually for weather protection or as a food source.

To get rid of spiders in your car, prevent their entry. Spider-proofing your car’s interior is easy and can make driving more enjoyable.

Yet, this may not be in the mind of the spiders; car access can be easy as there are so many entrances besides trying to squeeze past rubber seals around your door.
Here’s some of the best ways how to deal with spiders:

1. Don’t Park Car in Vulnerable Areas

If you must park on spider-friendly surfaces, you’ll have a tougher time keeping spiders out. All arachnids, including Black Widow spiders, prefer dirt, grass, and vegetation that sticks under your wheel arches.

Cockroaches also like these locations. First, park in spider-free zones. Concrete driveways can help protect your car from spiders and vermin.

2. Maintain a Clean Vehicle

Spiders thrive in places with food and hiding spots. If you don’t keep your car clean, it presents both these conditions and makes it more likely that you’ll encounter a spider while driving.

Food attracts flies, which attract spiders that hide under car rubbish and food droppings and scraps on your car’s floor. A car free of debris helps keep flies and spiders away.

3. Make A Spider Repellent Surface Spray

Spiders try to avoid certain smells, and luckily, many of which are appealing to humans, thus make great air fresheners and safe spider repellents. For instance, natural spider repellents include vinegar, eucalyptus, and peppermint oil.

In addition, cedar will also keep spiders away and make your car smell fantastic. (Learn How To Fix A Car Sun Visor)

  5. If there are any spiders in the automobile, you can quickly get rid of them by spraying the essential oil spray directly onto them.

2. Make Sticky Traps

Use a lethal spider management method to deal with a spider infestation, and avoid using harmful chemicals you find in the products from home improvement stores. Make your sticky traps ready for any spider problem.

Homemade Sticky Traps

  • 1 cup of water

  2. Cook until you have glue-like consistency.

  4. Place traps under car seats, trunks, or in other areas where you have seen spiders. Replace the traps as needed, so they stay effective.

Why Spiders Enter Your Car?

Spiders like to hide inside the door and window frames during the colder months. This is because the spiders are disturbed by the vibrations in the car’s skeleton, which causes them to move to more stable locations like the steering wheels, air vents, and behind mirrors.

They also enjoy hiding beneath the hood during the day in things far from the engine where they can still gather debris like leaves. Once inside, they can crawl through cracks to the interior and wreak havoc while you’re driving.

Because spiders prefer to conceal themselves in shadowy, isolated areas, clear your car of clutter and unnecessary stuff.

To prevent attracting more insects that spiders would like to eat, remove any trash, rubbish, and even stray leaves that may have been blown into your car.

To prevent spiders from causing infestations, vacuum and clean your car; spiders will soon dwindle after your car offers nothing.

Seal Entrances

Since spiders may squeeze into small spaces like holes in your car, covering them up with rubber may be necessary to prevent spiders from crawling in.

Around doors and windows, look for any cracks or broken areas. If you notice any dirt or debris clogging your car doors rubber seals, clean them using a sponge or cloth.

Spider Repellents

There are synthetic and natural spider repellents you can apply in your car. However, given that cars are small, enclosed areas, it’s best to avoid inhaling too many chemicals and use natural scents spiders hate.

The essential oil will help repel spiders. Choose essential oils, such as peppermint oil, citrus, and rosemary, and with these, you can spray behind mirrors and air vents, side mirrors, and around your door trim to stop spiders lurking.

You can also use a cotton bud dipped in the solution for areas that won’t work with a spray.

Eucalyptus leaves are another non-toxic repellant spiders hate. You can keep these in your glove box or trunk.

You can add a few drops of dish washing detergent as this will make the solution more effective for getting rid of spiders in your car and other insects and help them stick to hard surfaces in your cars enclosed spaces.


Bright lights attract spiders, so keep them off. If you’ve discovered an infestation, keep exterior lights off at all times, even when driving; turn them off when you park.

Spider Sticky Traps

How To Kill Spiders In Car?

You can kill spiders in your car with mechanical or chemical methods. Some mean you must catch them to get rid of spiders and physically kill them. The others mean you can kill them by leaving something for the spiders in your car.

Here are a few ways to kill spiders in your car:

  • Spider Traps
  • Sprinkle Diatomaceous Earth
  • Chlorine Oxide Car Odor Eliminators

1. Spider Traps

This is the best approach to capture and eliminate large spiders infesting your car, such as brown recluse, black widow, and hobo spiders.

The sticky traps entice the spider from its hiding place in your car, spiders tread on the trap, and you’ll find the spiders stuck there until they die.

You can keep the trap inside your car as it sits idle for some time to deal with spider infestations. When you return, you’ll discover a few spiders attached to it, possibly dead.

2. Sprinkle Diatomaceous Earth

Diatomaceous earth is a great way to get rid of spiders. Dust this throughout your car on the floor and around the trunk or seats.

For spiders in your car, it’s a deadly chemical that enters the body to cause dehydration.

Shut your car door after applying diatomaceous earth for a period, and you could find plenty of dead spiders.

Note, you need to use food-grade diatomaceous earth as it is safe for humans and pets, although a good vacuum won’t hurt before you use your car again. (Learn How Much Do Carports Cost)

3. Drop A Chlorine Bomb

This substance is frequently referred to as a chlorine bomb for spiders. This is so that the gas dispersed throughout your entire car’s interior may reach and kill spiders no matter where they are.

Although the harsh chemicals are primarily employed as odor eliminators, they are effective in killing spiders.

Combine the powder with one ounce of water. For about an hour, keep the cup of water in your car. Ensure the windows are closed, and the doors are sealed to prevent the gas from escaping.

Place the automobile in the garage and ensure your car interior is not exposed to sunshine as this breaks down chlorine, which could render the poison ineffective. The spiders will all be dead when you return and open the car after a bit.
