Ever had a spider crawl across your car dashboard, or out from behind your wing mirror? Here’s how to keep spiders out of your car.

SPIDERS IN CARS. They seem to be clogging up my Facebook newsfeed at the moment, and there’s a recurring question… how do you keep spiders out of cars? The short answer is, you can’t, but you can do things to reduce the chance of them making their home in your car.

And, there’s good reason for wanting to keep them out of your car beyond frightening you when you least expect it. Indeed, a huntsman falling onto a driver has been blamed for causing a multi-car collision near Sydney in the Blue Mountains. Apparently, the spider fell from the roof of the car and onto the driver’s head, causing him to swerve into oncoming traffic. Luckily, no-one was hurt.

More than the potential for causing a collision, spiders setting up camp inside your car can cause problems with components, although that’s rarer here than it is in other countries. But that didn’t stop Ford boffins from developing a special spider screen that sits inside fuel lines and prevents spiders from climbing inside and building a web. It was specifically intended to prevent the Yellow Sac spider from nesting inside fuel lines, as it’s cocoon-like web can easily cause blockages and potentially damage the engine. This filter was rolled out with the Focus RS.

In Australia, the issue isn’t so much with spiders building dense webs in cars, more that they crawl into out of the way places, build webs and have spider children who then go on to build other webs. And so on. That’s when you’re more likely to get a sudden appearance form an eight-legged free-loader. So, what can you do to keep spiders out of your car?

How to keep spiders out of your car

Keep it clean

By keeping your car nice and clean, inside and out, then you’re reducing the opportunity for spiders to find a home and remain undisturbed for years to come.

Look at where you’re parking your car

Parking your car under trees is a sure-fire way to see spiders make a home for themselves in the nooks and crannies of your car. Especially if it’s raining. Far better hiding inside a car than under a leaf in a tree.

A regular squirt with insect repellant

There are some very effective surface sprays that you can buy and squirt up under wheel arches, at the base of windscreens or inside wing mirrors. Just remember to wipe down the surface once you’ve sprayed it to ensure you don’t have any surface spray on the actual paintwork. Once you’ve done that, the Interweb suggests a cotton tip dipped in peppermint oil and wiped around the edge between the mirror and the housing will keep the spiders from coming back.
Another tip, according to the Interweb, is lemon. Peel the skin from a lemon and rub the pitchy part of the rind onto your air-con vents inside the car, apparently, spiders hate lemon. Who knew?!

Keep leaf litter from building up

Check areas like the base of the windscreen (or at the base of the rear windscreen in a sedan, or the corners of the bumper on a hatchback) for leaf litter buildup, as this can provide a great little home for spiders to crawl into and hide. Beyond just being a great place for spiders to live, the rotting leaves if not regularly cleaned out can cause rust and rot in places you don’t want rust or rot to occur.

2020 Toyota Corolla sedan review


  1. I drive 400ks still spiderwebs on my rims at the end! Never seem the actual spider just the web 🐜🐜 time for a pet praying mantis 😉

  2. Every year I get the same person that sprays my house for spiders / insects to do my car as well. They spray a mist around the mirrors, around the car and inside. A natural product and I never get any spider webs or spiders. They do it for free when they do your house, safe for cars, paint work etc.

  3. I’ve had the occasional spider or gecko on the outside of the car and I usually stop to let them off.
    The wildest event was about 6 months ago when I was riding somewhere on the motorbike (open face helmet with visor up) and a male huntsman ran up my face and over the top of my helmet and I think it nestled down on the back of my neck for a bit.
    It gave me a fright but I knew it was a male huntsman (non-poisonous) which is easy to tell by the shape of the body as it went across in front of my left eye. Mates say that I knew it was a male because I could see his balls.
    Being on a motorcycle in traffic – the opportunity to do the “I’m on fire” dance was not an option :/

  4. I have had a couple of run in’s with huntsman spiders in my car. Most recent one ran across my dash, so I quickly pulled over and climbed out the passenger side door. Another time it was hiding on the inside under the sun visor. Doesn’t help that I’m arachnophobic.

  5. I know this is a very old board but I can’t help but give advice.
    Once or twice a week park your car out in the open sunshine all day on a hot day where the temp inside gets ridiculous. Any spider or other insect or animal will perish due to the extreme heat. You’re welcome

  6. We have a metallic emerald green sedan, a white ute and a black coupe all parked in the front of our 5 acre property. It is the green car that gets cobwebs all over it in every nook. Don’t see the spiders. I wash it and they appear the next day. Nothing on the white or black cars. I’m guessing its the green, like trees etc but I would like to know if anyone else has noticed.
