How to Stop Pack Rat Damage From Destroying Your Car’s Engine

Pack rat damage is a big concern for people in Vail, Rita Ranch, and other outlying communities around Arizona.

These pests are known for gathering bean pods, plants, and just about anything they can carry, then using it to build their nest. The goal is to stay safe from predators, like owls, coyotes, bobcats and hawks. But when these nests are built in your car, the pack rats could lose their home and your engine could be toast.

Why Cars?

Cars are a common culprit of pack rat damage. That’s because they provide safe refuge from natural predators. If your car is parked in a garage, you might be at an increased risk. Garages aren’t accessible by predators, making your enclosed spaces even more enticing for a nest.

We see a lot of people come into our shop with chewed wires and brush under their hood or above their gas tank. When this happens, we know who to blame – pack rats.

Here’s how you can prevent pack rat damage from destroying your car’s engine and draining your pocketbook.

Stay Alert

Look around your yard. Do you see any large bundles of bean pods or plant debris? How about rat droppings? If you notice any signs of pack rats, or if you see a pack rat nest forming in your yard, capture the rat and get rid of the nest.

If you just get rid of the nest, you force the rat to find a new home. That new home could be your engine. Capture the rat and set it free in the many open spaces surrounding Vail. This way you’re safe from damage and the pack rat is safe to build a new home.

Rat Proof Your Garage

It doesn’t take much to let pack rats into your garage. These critters can get inside a hole as small as a nickel. Rat proof it by sealing off or securing all open spaces or holes.

If possible, avoid storing big boxes or yard items close to where you park your car. Any new nesting place you provide is another invitation for the pack rats to welcome themselves into your garage.

Maintain Your Landscaping

We’re living in the pack rat’s natural environment. The vegetation in your yard is their natural home. Keep your landscaping well-groomed so you can see under and behind the bushes or plants. This will make your yard less desireable to build a nest.

Keep the Lights On

Lights are another deterrent for pack rats. It makes it harder for these rats to be seen by predators, which makes your car a less desireable place to call home.

When Pack Rats Strike

If a pack rat struck your car, you are at an increased risk for a repeat attack. Pack rats leave their mark like dogs. When their scent is in your engine, other rats sniff out your car as a nesting spot.
When a pack rat strikes, bring your car into us. We’ll do a thorough cleaning on your engine to minimize the risk of another rat making its home in your car. We’ll also make any necessary repairs to the damage under the hood or in your car. When you drive away, you’ll have a lower risk of seeing another pack rat ruin your car’s engine.

How To Get Rid Of Rat Urine Smell In a Car In 7 Steps (with Pictures)

When it comes to rodents, you can count on one thing—they’ll pee on anything and everything! What’s even worse, is the fact that they love to pee on stuff that we love most. Things like food, furniture, stationery, and even cars.

Ignoring the deed is not an option. Rat urine smells so bad that it will keep you from using your car eventually!

Luckily, there are ways to get rid of the smell. In this article, we’ll look at 7 steps to ridding your car of the smell of rat urine.

Tools & Materials

Preparation is important if you want to effectively clean all the urine and disinfect the affected areas in your car. You’ll have to make sure you have everything you’ll need, or you’ll find yourself repeating the same process over and over.

The tools and materials needed for this job include:

  • Feet covers
  • Coverall
  • Rubber gloves
  • Respirator mask
  • Ultraviolet light source
  • White vinegar
  • Water
  • Disinfectant
  • Old rag
  • Essential oil
  • Craft knife
  • Half-pint mason jar
  • Thumbtacks
  • Glue

How To Clean Rat Urine In A Car

1. Shield Yourself

Before you do anything, cover your face, hands, feet, and any other body area that’s exposed. We don’t want any of that waste matter to get in contact with your skin.

According to the Center for Disease Prevention and Control (CDC), rat urine is home to different bacteria—the kind that can compromise your health. Some of the diseases caused by those bacteria can’t be cured through conventional means. Leptospirosis is the most common one, and it can sometimes be fatal.

Never forget what Benjamin Franklin once said; “An ounce of prevention is worth a pound of cure.”

2. Trace The Origin Of The Smell

Where’s that smell coming from? You’ll have to find it to thoroughly clean the affected area. Rat urine is always musky and smells like ammonia. Part of the reason is the bacteria found in it.

If the smell doesn’t lead you to the source, you should use a black light. Sometimes referred to as UV light, the black light usually makes urine glow in the dark. It will show you where the smell is emanating from in seconds.

3. Roll Down All Windows and Open All Doors

The goal here is to make sure you’re not only not choked by the smell of urine, but also that of your cleaning products. Some of those products have volatile organic compounds (VOCs) and several other harmful chemicals that could cause chronic respiratory complications, headaches, and several allergic reactions. Especially for an asthmatic person.

Make sure air is circulating in that car before you start cleaning.

4. Mix The Perfect Solution

Mix 2 tablespoons of vinegar with 1 pint of water, pour it into a spray bottle and start spraying on the areas where you’ve spotted urine. Let it soak for 20 to 30 minutes, then wipe it off.

While the interior is soaking, move on to the car engine. But this time, we don’t want you to use vinegar. Vinegar looks harmless but it could easily hurt your car engine and any other metal parts by catalyzing the rusting process. Instead, we’ll use baking soda. You could mix it with water to form a solution or a paste. Either way, it will get the job done.

5. Apply Disinfectant

After you’ve wiped off all the vinegar and baking soda from all those surfaces, apply disinfectant sparingly everywhere but the engine. We have to exercise caution because we don’t know what chemicals are in the disinfectant, or if the ones that are there can react with the engine’s components.

6. Mask The Smell

Even though we’re done with the hard part (cleaning), you may still smell urine—that and a little bit of vinegar. So to mask those odors, we need to make a naturally-scented air freshener.

2/3 of the jar should be filled with baking soda. Add 20 drops of your essential oils in there, close it, and start shaking. Shake until the oils are evenly distributed. Once you’re done, remove the lid and replace it with cardboard.

Make sure the cardboard is slightly larger than the jar’s lid. It’s now our new lid, and you should be able to attach it to the jar using glue or tape.

Once you’re certain that it’s secured, start poking holes in it using thumbtacks. Finally, place the jar in your car’s cup holder, and leave it for 3 to 4 days.

7. Throw Away Anything Disposable

Anything that has been exposed to the urine has to be disposed of. Should you feel different (if they are still reusable), soak them in boiling water for a few minutes, disinfect, wash, rinse, then hang them outside to dry.

Frequently Asked Questions

Can the smell of rat urine go away without treating it?

We’re not sure that’s possible, seeing as rats always go back to the same spot they urinated. That smell will remind them there’s a territory that has already been marked, so they don’t have to mark another—female rats are more notorious for marking territories.

But if they don’t come back, the smell will likely go away in 7 to 10 days.

Will disinfectants get rid of all the bacteria found in the areas that had rat urine?

Disinfectants are pretty effective when it comes to killing bacteria. As long as you apply enough of it, and wipe thoroughly, all the bacteria will be gone. Alternatively, you could mix bleach and water. The solution will certainly kill all the germs and mask the odor.

Don’t use it on the car’s interior cloth fabric or leather, though, as it could cause serious damage.

How dangerous is rat urine?

Potentially pretty dangerous. Although rare, once you’re exposed to it you could get Leptospirosis or find yourself in a hospital bed grappling with meningitis or Weil’s disease. And even if you don’t touch it, inhaling those particles in the air is just as dangerous, since you could develop Hantavirus.

Final Thoughts

If you’ve done everything but you can still smell that terrible odor, repeat the whole process—you might have missed a few spots. Also, don’t forget to close all the doors and windows whenever you park the car in the garage to help prevent rats from getting into your car. Rats love to move under the cover of darkness.

How to get rid of rats in car engine bay

Rats in the car engine bay can cause devastating damage to the vehicle’s electrical system, insulation, and other components. These pests can chew on wires, create nests, and leave behind droppings that can clog filters and cause corrosion. If you suspect that your car has become home to rats, it’s crucial to take immediate action to remove them and prevent further damage.

In this comprehensive guide, we will delve into the effective methods to get rid of rats from your car engine bay. We will cover preventative measures, non-lethal deterrents, and lethal traps to ensure you can restore your vehicle to a pest-free state.

Prevention is always better than cure, and the same applies to rat infestations in car engine bays. By following these preventative measures, you can significantly reduce the risk of attracting rats in the first place:

– **Keep your car clean:** Regularly clean your car’s engine bay to remove food debris and nesting materials. This includes vacuuming, wiping down surfaces, and removing any clutter.

– **Inspect your car regularly:** Check for signs of rat activity, such as droppings, chewed wires, or nests. If you notice any suspicious signs, take immediate action to prevent further infestation.

– **Eliminate food sources:** Rats are attracted to food, so avoid leaving any food wrappers or scraps in your car. Keep pet food securely stored and seal any potential entry points through which rats could access food.

– **Seal entry points:** Inspect your car for any gaps or holes that rats could use to enter. Seal any openings with caulk, steel wool, or expanding foam.

If you have already discovered rats in your car’s engine bay, it’s time to take action to drive them out. Before resorting to lethal traps, consider these non-lethal deterrents to humanely remove rats:

– **Ultrasonic pest repellers:** These devices emit high-frequency sounds that are inaudible to humans but deter rodents. Place these repellers in the engine bay to keep rats away.

– **Mothballs:** The strong scent of mothballs can repel rats. Place mothballs in mesh bags and hang them in the engine bay.

– **Ammonia-soaked rags:** Rats dislike the smell of ammonia. Soak rags in ammonia and place them in the engine bay to create a deterrent.

– **Electric rat traps:** These traps deliver a non-lethal electric shock to rats, discouraging them from returning to the area.

If non-lethal deterrents fail to resolve the rat infestation, you may need to resort to lethal traps. These traps are designed to kill rats quickly and humanely. However, it’s crucial to follow the instructions carefully and dispose of trapped rats responsibly.

– **Snap traps:** These classic traps are effective in killing rats. Use peanut butter or other bait to attract rats and place the traps in areas where they are likely to travel.

– **Glue traps:** Glue traps hold rats in place using a strong adhesive. Place these traps in strategic locations and check them regularly to remove trapped rats.

– **Poison bait:** Poison baits are effective in eliminating rats but can also pose a risk to other animals and humans. Use these baits with extreme caution and follow the instructions carefully.

Once you have successfully removed the rats from your car engine bay, take the following steps to prevent their return:

– **Clean and disinfect the area:** Thoroughly clean the engine bay with a disinfectant to remove any remaining rat droppings or urine.

– **Inspect and repair any damage:** Check for any damage caused by the rats and repair any chewed wires or damaged insulation.

– **Continue preventative measures:** Continue to follow the preventative measures outlined above to prevent future infestations.

Getting rid of rats in your car engine bay is essential to protect your vehicle and prevent costly damage. By following the steps outlined in this guide, you can effectively remove rats, prevent their return, and restore your car to a pest-free condition.
