Do Cockroaches Crawl Inside Your Mouth When You Sleep? – (Updated For 2024)

One of the worst things I can imagine is sleeping with my mouth open and a cockroach crawling inside of it. This has been an old wives tale that’s been talked about since I was a small child, but is there any validity to it?

In this guide, we’ll be talking about if a cockroach would willing to crawl into your mouth when you’re sleeping, and if this is a fear that is warranted.

Do Cockroaches Crawl Inside Your Mouth When You Sleep?

Yes, it’s possible that cockroaches might crawl into your mouth while you sleep, but it’s pretty unlikely since roaches are afraid of humans. Roaches generally are smart enough to stay away from your mouth, even though it is warm and moist.

Cockroaches are known to invade even the most protected of places as long as they have an opportunity to. However, when it comes to our bodies, we all want to be sure that cockroaches know their limits. 

Do Cockroaches Crawl Inside Your Mouth When You Sleep

While the mouth is warm and could pass for a cozy hiding spot for them, they are unlikely to venture in there. This is because superseding their love for comfort and food is their need to stay alive. When they sense the air coming out of your mouth, they know that you’re alive- which to them bleeds “do not enter!”

If at all they enter (which is rare), they’ll get out immediately. However, despite the short time spent there, they can deposit harmful pathogens that can make you very ill.

Why Do Cockroaches Crawl In Your Mouth?

Generally speaking, cockroaches are terrified of humans and will quickly scurry away, this means it’s unlikely that cockroaches will crawl into your mouth, but not impossible. So why would roaches crawl into your mouth?

  • They Are Looking For Food and Water: 99% of what cockroaches do revolves around finding food and water, they are built for survival. Unfortunately, your mouth can seem like the perfect place to find food and water for roaches, so they might be tempted to venture into your mouth when you’re sleeping. That being said, this isn’t going to be their first choice, and they will have to be extremely desperate to venture into your mouth.
  • They Think It’s A Safe Spot: Other than looking for food and water, roaches are also constantly searching for a safe place from predators. Although they generally see humans as predators, it’s possible that they mistake your mouth as simply a hole to hide in.

Along with this, cockroaches can crawl into your ear when you sleep which is even more terrifying to me!

To prevent them from flying onto your body at night while you sleep, turn off your bed lamps because they are attracted to light. 

What Happens If You Swallow A Cockroach?

Firstly, that has to be the most disgusting thing that can happen to a person as far as cockroaches are concerned.

Now, to answer the question, it would depend on the circumstances involved. If your stomach acid is quick enough to act on the cockroach, it gets broken down and digested. However, cockroaches are known to carry a barrage of bacteria such as Salmonella and E. coli which can cause diarrhea and vomiting, so ingesting it can be harmful. If it gives you any solace, many people do eat cockroaches on purpose!

On the other hand, you have a bigger risk of falling sick if your stomach acid is not quick enough to digest it, and nullify the effects of the bacteria. Fever, chills, and ultimately listeriosis (a bacterial infection) could result.

According to the American College of Allergy, Asthma, and Immunology, asthmatic and cockroach-allergic patients are likely to develop these if they swallow a cockroach:

  • Muscle cramps
  • Fever
  • Salmonellosis
  • Diarrhea

Although roaches have the ability to transmit diseases, generally speaking, roaches aren’t very dangerous.
