Using spider spray in your car can seem like a quick and easy way to get rid of any creepy crawlies, but there are a few important considerations to keep in mind before reaching for that can. In this article, we’ll go over the pros and cons of using spider spray in your car and provide some safer alternatives for keeping spiders away.

The Risks of Using Spider Spray in Your Car
Most spider sprays contain strong chemicals like pyrethrins, pyrethroids, and other insecticides that are designed to kill spiders and other bugs quickly. While effective, these powerful chemicals come with some significant risks:
- Respiratory irritation – The fumes from most spider sprays can irritate your nose, throat, and lungs if inhaled, especially in the confined space of a car.
- Skin irritation – The chemicals can cause irritation or even chemical burns if they come into contact with your skin.
- Toxic residue – Spider spray leaves behind a toxic residue that can spread throughout the inside of your car, contaminating surfaces and the air inside.
- Damage to surfaces – Some chemicals in spider sprays can damage or stain leather, plastic, and other surfaces inside your car.
- Harm to pets – Pets exposed to residues or fumes from the spray may experience respiratory distress, skin irritation, or other health effects.
Repeated use of chemical sprays also allows populations of spiders to build up resistance over time.
Is It Safe to Breathe the Fumes in an Enclosed Space?
Using most spider sprays in an enclosed space like a car is not recommended. Here’s why:
- The fumes can be concentrated – Without proper ventilation, the fumes have nowhere to go and can build up to high concentrations inside the car.
- Longer exposure – Sitting in the car means you’re exposed to the fumes for longer than just a quick spray treatment.
- Repeated exposures – Frequent use of spray over time increases your cumulative exposure to the chemicals.
High chemical concentrations plus longer, repeated exposures increase the risk of adverse effects like:
- Headaches, dizziness, nausea
- Eye, nose, throat, and lung irritation
- Coughing or breathing problems
- Allergic reactions
The effects can be worse for those with respiratory conditions like asthma. It’s best to minimize inhalation exposure by avoiding spray use in enclosed spaces whenever possible.
Tips for Using Spider Spray More Safely
If you do opt to use chemical spider spray in your car, follow these tips to reduce risks:
- Roll down windows – Open up the car as much as you can to allow for ventilation while spraying and afterwards.
- Use sparingly – Use the minimal amount needed rather than extensively coating surfaces.
- Don’t remain in car – Exit the car right after spraying to avoid breathing concentrated fumes.
- Wipe down surfaces – Clean any visible residues off surfaces after the spray dries.
- Air out the car – Let the car air out for several hours before getting back in.
- Read labels carefully – Follow all directions and heed health warnings.
Take extra care if spraying near ignition sources, as many spider sprays are flammable.
Safer Alternatives to Spider Spray
Using spider spray safely in your car takes effort. You may want to consider some of these simpler, non-chemical methods to keep spiders away instead:
- Remove debris and clutter – Spiders love hiding in dark undisturbed areas like under seats and in trunk crevices. Keeping the car interior clean and clutter-free leaves fewer places for them to hide.
- Vacuum regularly – Use crevice tools to vacuum up any existing webs and spiders. Pay close attention near vents and small spaces.
- Use essential oils – Apply diluted essential oils like peppermint, tea tree, or eucalyptus oil to cotton balls and place them in problem spots. Spiders dislike the strong scent.
- Seal entry points – Caulk or seal gaps in doors, windows, trunk, etc. to block spider entry points into the car.
- Install nets – Mesh nets over air vents can prevent spiders from crawling inside through the ventilation system.
- Use UV flashlight – UV light causes spider webs to glow, making them easier to locate and remove at night.
With some thorough cleaning and proofing, you can keep your car spider-free without the risks of chemical sprays.
Key Takeaways
- Spider sprays contain strong chemicals that can irritate lungs and skin, leave toxic residues, and damage car surfaces when used in an enclosed space.
- Spray fumes are concentrated inside a car, leading to greater and longer chemical exposure that can cause adverse health effects.
- Never remain inside a car during or after spraying. Roll down windows and air out the car thoroughly before re-entering.
- Non-chemical methods like vacuuming, essential oils, sealing cracks, and removing clutter can help safely ward off spiders.
- Read labels carefully and always err on the side of caution when using chemical sprays inside your vehicle.
The Bottom Line
While using spider spray in a car may seem like an easy spider solution, the potential risks make it a poor choice for enclosed spaces. With some diligent cleaning and proofing efforts, you can keep your car free of spiders without exposing yourself to the dangerous chemicals found in most sprays.
