How to Remove Spiders from Your Car

Spiders in your car can be more than just an annoying inconvenience—they can create an unpleasant driving experience and even lead to infestations if left unchecked. Whether you’ve noticed a single web in the corner or a spider crawling across the dashboard, it’s important to take action and reclaim your car from these unwanted passengers.

The first and most important step in removing spiders is to thoroughly clean your car. Once your vehicle is spotless, you can move on to the fun part: trying out natural and non-natural pest control methods that will ensure your car stays spider-free.

Why Spiders Are Attracted to Cars

Ever wondered why spiders choose to set up camp in your car? Understanding their motives can help you put a stop to their unwelcome visits.

  • Warmth: Cars offer a cozy environment, especially during the cooler months, making them the perfect hideaway.
  • Dark, Hidden Spaces: Tight spaces like vents, under seats, and door panels are like luxury suites for spiders.
  • Food Sources: If bugs like flies or mosquitoes are attracted to crumbs or trash in your car, spiders will follow their next meal right inside.

By tackling these attractions, you’ll already be one step ahead in the battle against spiders.

Step 1: Clean Your Car Thoroughly

Think of cleaning your car as the foundation for all other pest control methods. Spiders might not be hunting for leftover snacks, but the bugs they eat certainly are. A clean car removes the food source and makes it less appealing for both insects and their eight-legged predators.

How to Clean Your Car to Remove Spiders

  • Vacuum Every Nook and Cranny:
    • Use a handheld vacuum to tackle the floors, seats, vents, and crevices.
    • Focus on dark, hidden spots where spiders might be lurking or spinning webs.
  • Wipe Down Surfaces:
    • A microfiber cloth and car-safe cleaner can do wonders for your dashboard, door panels, and other surfaces.
  • Remove Trash and Clutter:
    • Old food wrappers and containers are a beacon for insects. Toss them out to eliminate temptation.
  • Clean Carpets and Mats:
    • Shake out floor mats and give them a good vacuum. If they’re particularly grimy, consider shampooing them for a deep clean.

With your car sparkling clean, you’re ready to move on to the next step.

Step 2: Natural Pest Control Methods

For those who prefer eco-friendly solutions, natural pest control methods like essential oils and diatomaceous earth offer effective, chemical-free options.

Essential Oils to Remove Spiders (Our Top Pick!)

Spiders have excellent survival skills, so sometimes the best option is just convincing them to leave. Spiders hate strong smells and they "taste" with their feet, so certain strong-smelling essential oils have been proven quite effective at convincing spider to find somewhere else to live. These oils overwhelm their sensory systems, making your car a no-go zone. According to research cited by Healthline, both peppermint and chestnut oils are highly effective at keeping spiders away.

Peppermint Oil

Peppermint Oil is a spider’s worst nightmare. Its bold scent irritates their senses, and because they “taste” with their legs, contact with peppermint oil is particularly unpleasant.

Chestnut Oil

Chestnut oil is another proven repellent. The same study that highlighted peppermint oil’s effectiveness also found that chestnut oil contains compounds that spiders actively avoid, making it a fantastic alternative.

How to Use Essential Oils to Remove Spiders

  • Mix Your Own Spray Solution:
    • Combine 15 drops of peppermint or chestnut oil with 1 cup of water.
    • Add a few drops of dish soap to help the solution stick to surfaces.
    • Pour the mixture into a spray bottle.
  • Spray Away:
    • Target areas like vents, door seals, and dashboard crevices where spiders are likely to hide. Avoid electronics and sensitive upholstery.
  • Set Cotton Ball Traps:
    • Add a few drops of essential oil to cotton balls and place them under seats, in door pockets, or cup holders to keep the scent lingering.
  • Use a Foam Cannon for Full Coverage:
    • Mix your essential oil with water and car-safe soap in a foam cannon. Spray the foam all over your car, allowing it to reach into tight spaces like behind door mirrors and inside cracks and crevices where spiders like to hide.

Diatomaceous Earth

Looking for a natural pest control option that works without lifting a finger? Diatomaceous Earth might be your new best friend.

How It Works

This powder is made from fossilized algae with microscopic sharp edges. When spiders or insects crawl over it, the powder scratches their exoskeletons, causing them to dehydrate and die. It’s a slow but highly effective process.

How to Use Diatomaceous Earth in Your Car

  • Apply in Hidden Spots:
    • Sprinkle food-grade diatomaceous earth under seats, along door seals, and in dark corners.
  • Vacuum It Up:
    • After a few days, vacuum up the powder and any pests it’s taken care of.

Step 3: Non-Natural Pest Control Methods

If you need a little extra help, non-natural pest control methods offer powerful and efficient solutions.

Spider Repellent Sprays

Wet & Forget Miss Muffet's Revenge Indoor and Outdoor Spider Killer is a top choice for tackling spiders in and around your car. This spray creates a long-lasting barrier that repels spiders for up to 12 months.

How to Use Wet & Forget on Your Car

  • Prep the Area:
    • Clean the surfaces you plan to spray to ensure the product adheres properly.
  • Apply Strategically:
    • Spray along door seals, vents, and other entry points.
  • Reapply as Needed:
    • Follow the manufacturer’s instructions for reapplication, especially after washing your car.

Why It Works:

  • Provides lasting protection.
  • Safe for both indoor and outdoor use.

TERRO® Spider & Insect Trap

Not every solution needs to be a spray. The TERRO® Spider & Insect Trap offers a passive way to deal with spiders by luring them into a baited glue trap. Once they step inside, they’re caught on a sticky glue surface.

How to Use in a Car

  • Place Strategically:
    • Position traps under seats, in the trunk, or in any corner where spiders might hide.
  • Check and Replace:
    • Inspect traps regularly and replace them as needed.

Why It Works:

  • No harsh chemicals, just glue and an attractant.
  • Catches spiders and other crawling insects effectively.

Preventing Spiders from Returning

Once your car is spider-free, follow these tips to keep it that way:

  • Seal Gaps: Check door seals, vents, and other entry points for gaps where spiders might sneak in. Fix any issues.
  • Limit Open Windows: Keep windows closed, especially at night when spiders are more active.
  • Park Smart: Avoid parking near tall grass, bushes, or trees where spiders and insects thrive.

Why It’s Important to Act Quickly

A small spider problem can escalate quickly if left untreated. Spiders can lay egg sacs, leading to a full infestation, or clog your vents with their webs. Worse, a sudden spider appearance while driving can be a dangerous distraction. Taking swift action ensures your car stays safe and comfortable.
