Finding a small bug on your seat belt can be alarming. It is even scarier if it turns out to be a bed bug. If you are worried about bed bugs in car interiors, you are not alone. I understand how you feel.
The thought of these pests moving from your car to your bedroom can keep anyone awake at night. Ignoring them can lead to a serious problem every time you go grocery shopping or drive to work.
It’s not about how clean you keep your car; it can happen to anyone. I created this guide to help you know what to look for and how to remove them quickly. Let’s work together to make your car a relaxing space again.
Can Bed Bugs Live in Your Car?
Yes, bed bugs can live in your car. They can survive in the heat of summer and the cold of winter. If they have a hiding spot and a person to feed on every few days, they will stay. If you drive your car often, you are their food source.
Bed bugs can hide in the stitching of cloth seats, under floor mats, or in tiny cracks, such as where the seat belt connects. I’ve even seen them in the felt lining of a trunk lid. They do not need a mattress to live. Your car provides many dark, tight spaces that feel safe to them.
While they may not reproduce quickly in a car due to temperature changes, they can stay long enough to crawl onto your pants and follow you inside, which is the real danger you should be aware of.
How Do Bed Bugs Get in My Car?
Many people wonder how bed bugs can get into a clean car. The answer is simple: they hitch a ride. Even if your car is clean, you can still pick up bed bugs. One common way this happens is through your bags.
If you stay at a hotel with bed bugs, a bug might crawl into your suitcase. When you throw the bag in your car, the bugs might come out and look for dark places.
Bed bugs can also enter your car via used items. If you buy a secondhand car seat or pick up a chair from a yard sale and put it in your trunk, you might bring bed bugs with you. Visiting a friend’s home or sitting in a movie theatre can also let a bed bug cling to your jacket.
Just one pregnant female can create a serious problem.
5 Signs You Have Bed Bugs in Your Car
Before you start taking apart your car, make sure you are not dealing with a random bug or some lint. You don’t want to waste your time cleaning for no reason. Here are the signs I look for when I think there’s a problem with my truck.
First, check the seat seams for tiny black dots, which are bed bug waste, and it looks like someone used a fine-point marker to make specks in the fabric. Second, look for shed skins. As baby bed bugs grow, they leave behind clear, empty shells that crunch when you touch them.
Third, you may notice small blood stains on light upholstery if you accidentally squish one after it has fed. Fourth, if your car has a strange, sweet, or musty smell but is otherwise clean, it could indicate a large bed bug infestation.
Finally, if you see a flat bug that looks like an apple seed and is brown or reddish, you have confirmed the presence of bed bugs.
Tools I Recommend
- Vacuum with a crevice tool.
- Handheld clothing steamer.
- Stiff-bristle scrub brush.
- Disposable gloves.
- Bright LED flashlight.
Steps to Clear Out Bed Bugs in a Car
1. Remove Clutter and Floor Mats: First, take everything out of your car, including napkins, car seats, gym bags, and even the papers from the glove box. Put all fabric- or paper-made items into a sealed plastic bag right away.
Do not leave them in the driveway. Instead, place these items directly in a hot dryer for 45 minutes before bringing them back inside. You can’t treat the car effectively with sweaters and coffee cups in the way.
Pro tip: When removing the floor mats, do it slowly to avoid sending bugs into the air and onto your shoes.
2. Vacuum Every Crevice Thoroughly: Use the crevice tool to vacuum every nook and cranny. Focus on areas you usually ignore. Clean along the stitching where the seat back meets the seat bottom. Get into the crack where the seat belt retractor is.
Vacuum along the plastic trim where the carpet meets the door sill. The vacuum helps remove live bugs and eggs. After you finish, take the vacuum bag or canister outside to the curb trash can.
Don’t leave it in your garage overnight, or the bugs may come back.
3. Steam the Soft Surfaces Slowly: Now it’s time to see results. Heat at over 120 degrees Fahrenheit kills bed bugs and their eggs immediately. A clothing steamer is great for car seats. Hold the nozzle against the seam for about 10 seconds at each spot.
Moving slowly allows heat to reach the foam padding. If you move too fast, the surface gets hot, but bugs hiding deeper may survive. Be careful near electronics and the dashboard; steam can damage them.
4. Dust Hidden Cracks: After steaming, let the car dry, then put on your gloves. Take a small amount of Diatomaceous Earth on a brush tip or use a puffer bottle. Lightly dust it in hidden areas, like under the front seats and along the back carpet line.
This dust acts as a trap. Any bug that crosses it will start to dry out. Leave it for a few days without vacuuming it up.
How to Get Rid of Bed Bugs in a Car
You can remove bed bugs yourself using these simple methods:
Extreme Heat: On a hot day, parking your car in direct sunlight with the windows closed raises the temperature inside to about 130°F, which will kill bed bugs and their eggs. Cover the seats with black trash bags to trap more heat.
Deep Cold: On freezing days, leave your car with the windows slightly open so the cold air can get in.
Dichlorvos Strips: Hang chemical strips that release vapors to kill bed bugs. Seal the car for 48 hours after hanging a strip, then air it out for two hours.
Rubbing Alcohol and Steam: Spray bed bugs with 91% isopropyl alcohol, then steam them in a well-ventilated area to kill them on contact. This method works well for visible bugs, but it won’t remove hidden eggs deep within the seat foam.
Diatomaceous Earth: This powder dries out bed bugs by cutting their shells. It is safe for pets once it settles.
Plastic Garbage Bags: Use heavy-duty black bags to cover seats, as they trap heat effectively.
Vacuuming: Vacuum the car to remove bugs and eggs. Remember to empty the vacuum outside to avoid bringing bugs back in.
By using these methods, you can help get rid of bed bugs in your car.
Frequently Asked Questions About Bed Bugs in Cars
How long can bed bugs live in a car without a person?
Adult bed bugs can live for 5 to 6 months in cool conditions, but will die quickly in a hot car. It’s best not to leave the car unattended.
Do bug bombs or foggers work in cars?
It’s better to avoid them. The fog does not reach the inside seat cushions well. It only covers the surfaces and pushes bugs deeper into cracks.
What if I find bed bug eggs but no bugs?
Finding eggs suggests an adult bed bug was likely there. Vacuum and steam-clean the area right away, and treat it to remove any that might hatch.
Will washing my car help?
Regular car washes are not enough. Tell the detailer about the bed bugs. Focus on pest control before detailing, ideally with a hot-water extractor.
Can bed bugs live in my car engine or trunk?
They usually avoid the engine but can live in the trunk, especially in items like strollers or blankets. Check the trunk carefully, including the spare tire area.
You can remove bed bugs from your car using heat and patience. Use DIY steam and powder for small problems. If you still see them after 2 weeks, contact a pest professional who can safely treat vehicles.
