Why Do Cockroaches Crawl On You At Night?

Do you get the hibbie-jibbies whenever you see a cockroach darting around?

If so, imagine they crawled on you while you slept at night!

OMG! Why do roaches do that?


The 3 main reasons why these pesky insects might creep over you at night are:

  1. They’re attracted to the warmth radiating from the body.
  2. They’re searching for food, and you’re in their way.
  3. The cockroach got a whiff of your earwax, and it wants some.

No matter the reasons, there is no way you’d want these creepy pests crawling on you!

Let’s explore why cockroaches crawl on you at night and give tips on preventing that!

Why Do Cockroaches Come Out at Night?

Why Do Cockroaches Come Out At Night?

All this wouldn’t be a problem if roaches came out during the day. They could also do all their nightly duties during the day. Unfortunately, no, as nature had other plans!

Cockroaches are nocturnal creatures, which means they can only come out at night. They like to keep themselves hidden in the world’s tight, dark, and warm corners.

Once the sun goes down, these pests leave their abodes and scavenge for nourishment. This habit allows them to avoid potential predators or to whack by humans!

Unfortunately, this may also lead them to crawl on you at night!

Do Roaches Like To Live With Humans?

Do Roaches Like To Live With Humans?

Yes, of course, they do.

Human homes are perfect for shy little pests like roaches. There’s food, water, and plenty of dark, tight spots to live peacefully.

Even if you keep your home tidy with no traces of leftover food particles, humans are still present. We’re giving off heat and dropping dead skin cells and hair all over the place.

This drives the cockroaches to come crawling onto you at night in search of warmth and sustenance.

3 Reasons Cockroaches Crawl on You at Night

Reasons Cockroaches Crawl On You At Night

Cockroaches are resourceful and relentless in their pursuit of survival. Everything they do is for that very purpose.

Here are 3 reasons why they’d crawl on you at night:

1. Drawn to Your Body Heat

Drawn To Your Body Heat

When humans go to sleep, our core body temperature drops.

In this state, the body releases heat into the surrounding, which can be a cause of attraction for cockroaches.

After all, these pests are constantly searching for dark, warm, and compact hiding spots, so they’re naturally drawn to a sleepy human.

Although they’re usually scared away due to any movement, their survival instinct may still compel them to crawl toward you.


You can prevent cockroaches from detecting your body heat by covering yourself with a blanket and sleeping on a taller bed!

2. Just Passing by Looking for Food

Just Passing By Looking For Food

Do you like to eat in bed while watching a movie or your favorite TV show? If so, chances are you have leftover food bits on your bed or, even worse, on your clothes!

Cockroaches are scavengers, and if food crumbs are lying around, one way or the other, they’ll reach it even if it means crawling all over you!

So what to do? Simple, either stop eating in bed or clean up afterward. Get a vacuum cleaner and ensure that you sweep all over the bed and its surroundings.

Go one step further by changing your clothes and washing your face. This will ensure that no bits and pieces of food are left for the cockroaches to come crawling onto you!

Important Note

If you ever feel a cockroach crawling on you, clean that area thoroughly. This is because cockroaches are carriers of numerous diseases, bacteria, and viruses harmful to humans!

3. It Wants To Get Into Your Ears

It Wants To Get Into Your Ears

Have you ever heard or read stories about insects going up people’s ears? Total nightmare!

Many insects look at human ears and think ‘dark and cozy’. Cockroaches are attracted for an additional reason, eating the ear wax!

Believe it or not, earwax gives out an odor that is not that different from fermented cheese, beer, and other foods.

This odor can attract roaches; if they crawl inside your ear, it’ll be a huge pain in the head to get them out!


Clean your ears regularly with a washcloth to prevent excessive wax buildup.

Be careful not to use Q-Tips for deep cleaning, as they can damage your eardrums!


Cockroaches are a menace no matter where you go.

You’ll always run into them scampering around, and even though they’re afraid of people, they won’t hesitate to crawl on you at night.

The three main reasons why they do this is because:

  1. They’re attracted to your body’s heat.
  2. You left bits and crumbs of food on your bed and clothes.
  3. They like how your earwax smells, and they want in.

As long as you keep your house neat and clean, you’ll never have to worry about cockroaches crawling on you at night.

However, if you notice the roaches getting a bit too friendly around you, it’s probably time to call in the pest control professionals!
