Is It Safe to Sleep in a Moldy Tent

is it safe to sleep in a moldy tent

Since mold thrives in warm, moist environments, it’s absolutely common to find it horridly multiplying in tents. All it takes is for you to rapidly shove your tent into a closed, poorly aerated space before it completely dries. But now isn’t the time to dwell on the past. You’re left with two choices: sleeping next to the yucky mold or leaving your body for the vicious bugs to feast upon. In that scenario, I think it’s pretty clear that it’s safe to sleep in a moldy tent.

In this article, I’ll explore this topic in detail. You’ll know what’s exactly bad about mold, and how to clean it with nothing but soapy water.

What Is Mold

Mold is a type of fungus that primarily exists in moist areas. Although it’s commonly known for being black or green, it can also be white, orange, or purple.

Even though it looks super gross to us, the environment is always grateful for its presence. Without mold, we would’ve had tons of dead leaves, plants, and trees that can’t be naturally decomposed.

But how did that mold reach your tent? Well, any actively growing mold releases thousands of spores into the air. They keep aimlessly floating around until they find a moist surface that they can adhere to. If you store your tent while it’s still wet, you’ll be more likely to find it devoured by mold after a couple of days.

So, Is Mold Dangerous

Yes and no. As I said, mold is present everywhere around us. You’re literally inhaling its spores on a daily basis. Nothing goes wrong because our bodies can deal with this negligible amount of spores.

It starts to rear its ugly head when you sit by an active focus that keeps spewing microscopic spores into your face. But even then, the risk can be quite variable between people.

For most of us, mold exposure will cause the typical mild signs of sensitivity like:

  • Sneezing
  • Runny nose
  • Red or itchy eyes
  • Skin rash

However, some people might be especially allergic to mold. They’ll experience more severe symptoms like:

  • Shortness of breath
  • Chest tightness
  • Coughing
  • Wheezing

And of course, people who have underlying respiratory diseases will be at a much bigger risk. Asthmatic attacks, for instance, can be triggered by long-time mold exposure.

Is the Black Mold Especially Dangerous

Between all the mold colors, people freak out the most about the black type. It’s widely thought to be so toxic that it can lead to death. Thankfully, nothing could be further from the truth.

Color is not an indication of how dangerous a mold may be,” says the official website of the Centers for Disease Control and Prevention (CDC). “There are very few reports that toxigenic molds found inside homes can cause unique or rare health conditions.”

How Can You Manage the Symptoms of Mold

If you started experiencing any of the mentioned symptoms, it’d be wise to get out of the tent to give your lungs a break by breathing clean, spore-free air.

Then, you can start alleviating the symptoms by the methods you normally use to control any typical allergy.

Corticosteroid nasal sprays, like Flonase, can effectively reduce airway inflammation.

Antihistamines can be a bit more efficient by calming the irritated immune system, which should instantly eradicate most, if not all, of the symptoms. Zyrtec and Claritin are two of the best OTC antihistamines that don’t have side effects.

If you want to steer clear of medications, you can rinse your nasal passages with warm water to flush down the spores and clear your airway. For a convenient application, you can get a portable nasal irrigator.

How to Clean Your Moldy Tent

Medically speaking, you probably won’t suffer from the symptoms of mold sensitivity unless you sleep beside moldy stains for more than one day.

In other words, if you didn’t notice the mold growth before your bedtime, you can ignore it, get a good night’s sleep, and handle it with a fresh mind on the next day.

However, this doesn’t apply to folks who already suffer from chronic respiratory conditions like asthma. In this case, you’ll need to start cleaning right away.

  • Step 1: Prepare Your Tent

    Remember, mold thrives in humid, closed areas. I’ve seen many campers trying to scrub moldy stains with the tent folded or lying flat on the ground. This is completely absurd because some water will inevitably creep through the tent fabric and create new infestations!

    Set up the tent as if you’ll be using it normally. If you have a rain fly, remove it. You’ll need plenty of sun and air to circulate through your tent.

  • Step 2: Wear Protective Gear

    As I said earlier, mold spreads to new areas by spewing its spores into the air. When you scrub it, you’ll surely agitate an extreme amount of spores. That’s why wearing a mask is an absolute necessity. And since some mold types can also release toxins, surgical gloves are crucial, too.

  • Step 3: Scrub It With Soap and Water

    Any mold growth compromises thousands of living cells glued over the surface with special tacky substances. Luckily, simple detergents, like dish soap, can effectively sweep them away. You’ll probably need some elbow grease, but your efforts will pay off at the end.

    After making sure that no moldy stains are still there, rinse the spot thoroughly to get rid of the soap and mold remnants. Lukewarm water will be better since it’ll fragment any remaining tiny stains.

  • Step 4: Entrust Some Natural Cleaners

    If the soap doesn’t seem to cut it, no worries! You can try scrubbing with a solution of 2 part lemonade, 1 part white vinegar, and a pinch of salt.

    “Why these,” you might ask? The citric acid present in lemon can quickly eradicate mold and mildew without being too harsh on your tent’s fabric.

    Vinegar shares the same properties since it’s based on a similar solution: acetic acid. It’s actually stronger than lemon, but some people may not appreciate its rather strong odor.

    Salt is a strikingly powerful substance that bacteria and fungus can’t tolerate. It works by sucking the moisture out of the mold cells, depriving them of the essence of their growth.

    And just like the last step, make sure to give your tent a quick rinse by warm water to remove any remnants.

  • Step 5: Leave It to the Sun

    I’m sorry to break it to you, but no matter how hard you scrub, you’ll inadvertently overlook some microscopic mold cells. Unless you possess Superman’s heat vision, you won’t be able to eradicate them yourself.

    Lucky for you, the solution is right above your head. The ultraviolet rays generated by the sun have a capacity high enough to kill mold spores, anthrax, streptococci bacteria, you name it!

    To ensure the best results, dry the moldy spot with a clean cloth and position it under direct sunlight. And of course, open the doors and windows to properly aerate your tent’s interior.

  • Step 6: Deodorizing

    Most of the time, scrubbing and sun drying should leave your tent smelling as good as new.

They might keep bugging you with an infernal smell, even if you can’t see any stains.

    In that case, you’ll need to use an enzymatic cleaner and deodorizer. If you’re unfamiliar, enzymatic cleaners contain biological substances that literally “digest” living cells.

    To use this cleaner, pour some drops into a cup of clean warm water and wipe it over your tent’s fabric. And that’s it! You shouldn’t rinse or dry it off. It’ll slowly diffuse into the fabric to hunt down all the mold cells lurking inside.

  • Step 7: Repair the Damage

    By now, your mold problem should be completely resolved. Nevertheless, you might be left to face yet another crucial issue.

    See, all the steps described earlier should be fairly safe on your tent’s fabric. But the actual possibility of damage boils down to your tent quality.

    The good news is, if your tent started fading and losing water resistance, you may not have to throw it away yet!

    Get a waterproofing spray and sprinkle on the affected spot. And just like the deodorizer, you should let it dry on its own. After enough time, the new protective coat will cause water to bead up and dry normally.


Is it safe to sleep in a moldy tent? Well, it’s by no means ideal, but it’s certainly better than sleeping in the open air. If you ever encounter this problem, just go to sleep and worry about it the next day.

If the growth is still fresh, consider yourself lucky! A quick scrub with water and soap should be more than enough. If you have access to lemonade, vinegar, and salt, use them to get the job done quicker.

Lastly, if your tent keeps stinking, you’ll need an enzymatic cleaner. This will hunt down and eradicate the mold cells by biological digestive enzymes.
