  • Spots like this (about the size of a quarter), caused by bed bug excrement, can bleed through fabric like a marker.
  • Eggs and eggshells, which are about an mm wide, as well as pale yellow skin that nymphs shed as they grow.
  • There are live bed bugs.

Are Bed Bugs Visible During The Day?

The bed bugs are tiny. However, they aren’t so small that you can ignore them during the day.
A full-grown adult bed bug is approximately 3/16th of an inch to 1/4th of an inch in size. 
Bed bugs are easily visible during the day if you know what they look like and where to look for them.
The reddish-brown bugs that make up bed bugs are flat and oval-shaped. Bed bugs and swallow bugs look pretty similar, but there are some differences.
It’s the baby bed bugs that are hard to spot. It’s because they’re translucent and microscopic. 
Perhaps baby bed bugs bite more than adult bed bugs. Without blood meals, baby bed bugs won’t grow and will die.

Are Bed Bugs Come Out In The Daytime?

Pests such as bed bugs are nocturnal. Their human hosts are stationary at night when they feed.
Therefore, bed bugs are most active at night.
When the bed bugs are well fed, they will hide in the hiding places that you will discover later in the post.
However, if humans were absent for prolonged periods of time, bed bugs would search for blood meals during the day.
Therefore, bed bugs are unlikely to come out during the daytime if you’re getting bites during the night.
You’ve to go looking for bed bugs in the places where bed bugs hide during the day.

Do Bed Bugs Bite During The Day?

Bed bugs in desperate need of blood will bite during the day if they haven’t eaten for months. 
It is not uncommon for bed bug bites to occur during the day in bed bug-infested new homes and apartments that have been sitting idle for months.
If the homeowner did not treat for bed bugs, the new tenants could get severe bed bug bites soon after moving in. 
They will take their chances on soft furnishings, such as a sofa, mattress, and any other soft furnishings when they sit on them.

Do Bed Bugs Bite Every Night?

They don’t. Bed bugs don’t bite or have their blood meals every night.
If bed bugs had the blood they needed, they would bite you every two weeks.
Following a blood meal, bed bugs will remain hidden until they become hungry again.
That’s one of the reasons you may experience bed bugs, but not see any signs of bed bugs, or physical evidence of them, for an extended period of time.
However, the biting becomes more frequent when the infestation becomes severe.
In other words, if the bed bug infestation is in its early stages, you won’t get bitten every day.

Where Bed Bugs Hide

The bed bug hides in many places when it isn’t feeding. In cracks around the bed frame and headboard, they can be found near the piping, seams and tags of the mattress and box spring.

You may find bed bugs in a heavily infested room:

  • You can find it in the seams of chairs and couches, between cushions, and in the folds of curtains.
  • The joints of drawers.
  • Electrical receptacles and appliances.
  • Listed under loose wall paper and wall hangings. 
  • At the junction where the wall and the ceiling meet.
  • Even in the head of a screw.

Bed bugs are only about the width of a credit card, so they can squeeze into small hiding places. Bed bugs can hide in cracks that can hold credit cards.

here are the eleven typical hiding places of bed bugs during the daytime – 

  1. Dresser drawers
  2. On the edges and covers of electrical outlets
  3. Soft upholstered furniture like accent chairs and couches
  4. Carpets and rugs 
  5. Tiny gaps and cracks on furniture
  6. Headboards and footboards

  8. Pillows
  9. Bed frame
  10. Behind photo frames and wall décor
  11. Cracks and fissures on the wooden floor

Do Bed Bugs Feed During The Day?

The bed bug population is most active at night. It is easier for them to rely on humans when we are very still and sleeping soundly on our beds. 
This does not mean that bed bugs do not feed during the day. In fact, bed bugs feed in a very unpredictable manner throughout the day. To summarize, bed bugs feed whenever they are hungry and if there is an accessible host lying perfectly still on the bed.
One feeding a week is typical for adult bed bugs. But that doesn’t necessarily mean that you won’t get bitten every night or every time you take a nap during the day for that matter.
You probably have several hundreds of bed bugs hiding in the cracks and crevices of your bedroom if you have even a mild infestation. It is possible for one female bed bug to lay up to five eggs every day and up to 500 in her lifetime.

How To Track And Find Bed Bugs At Day?

During the day, finding bed bugs can be quite a challenge. A bed bug infestation can be very frustrating, and it can easily spiral out of control when not handled properly at the earliest possible opportunity.
If you wake up in the morning with bite marks all over your body, it is best to track down and find the culprit during the day when you have more time to do so the sun’s light is still on your side. However, it is still recommended you secure a flashlight to hunt bed bugs in corners of your bedroom that are not exposed to sunlight.

In order to find bed bugs during the day, it is very important to identify and track the signs they leave behind. 

As a result of bed bug collapse on your mattress cover, reddish stains appear on your cover, bed bug droppings are about the size of a dot from a marker, and adult bed bugs are about the size of an apple seed.

To thoroughly check the entire bedroom for bed bugs, it is best to determine which section should be examined first and which corner should be examined next.

Thus, you will be able to maximize your effort without leaving any pillow or mattress untouched.

Here’s how to find bed bugs during the day in 3 steps

  1. Brighten up your room where you’re looking for bed bugs.
  2. Take a magnifying glass, your credit card, and a headlamp.
  3. Closely inspect the hiding place where bed bugs hide.

Let us explain.

The room needs to be brightened up as much as possible. It’ll make it easy for you to spot the bed bugs.

Bed bugs can also become lazy when they’ve eaten their blood meal due to more light.

You should open any curtains or drapes on the windows that are blocking the natural light.

Now take a magnifying glass, a credit card, and wear a headlamp if you can.

Bed bugs and their eggs and nymphs can be easily spotted with a magnifying glass in the tiny gaps.

A headlamp will be useful for focusing the light on these tiny cracks and fissures.

Next, you’ll learn why we recommend a credit card, but know that it’s a magic tool if you’re looking for bed bugs during the day.

Now, zero in on the places where bed bugs hide. 

Make use of your magnifying glass to see through cracks and gaps in hard surfaces such as furniture, floors, and bed frames.

Your credit card can be inserted in these cracks. And slowly pull the card out of these gaps. 

You’ll notice bed bugs sticking to the card if they are hiding in these cracks and gaps.

The card also has tiny white specks of dust and nymphs.

Check the seams or edges of soft furnishings such as mattresses and couches. 

Bed bugs hide in these folds. 

However, ensure that you remove any covers, such as pillowcases, couch covers, bedsheets, and mattress covers, from these soft furnishings.

Be sure to check under the couch and bed as well. Be sure to inspect soft furnishings for tiny gaps, folds, and edges.

In a home infested with bed bugs, bed bugs will be hiding in these places.

Bed Bug Behavior and Habit

When you understand how bed bugs behave (how they eat, live, and reproduce), you can discover an infestation before it becomes established and monitor your home after treatment for the presence of bed bugs.


  • Appear to prefer feeding on humans, but will eat other mammals and birds as well.
  • Easily travels 5-20 feet from established hiding places (called harborage) in order to feed on an animal.
  • Despite their tendency to be active at night, they may seek hosts in the daylight if they are hungry.
  • Feeding can take 3-12 minutes.
  • There may be rust-colored or tarry spots on bed sheets or in bug hiding places because 20% of the time adults and large nymphs will void earlier blood meals while still feeding.

Life stages/mating:

  • A bed bug must eat blood at least once before it can progress to the next stage of its lifecycle.
    • They can feed more than once.
    • Each stage also requires the molting of skin.
  • Males and females both need to eat once every 14 days in order to mate and produce eggs.
  • Females may lay one to three eggs per day and 200-500 eggs during their lifetime (6-12 months, but could be longer).
  • The life cycle of an egg may take four to five weeks if conditions are favorable.

Living conditions:

  • Despite their ability to survive and remain active at temperatures as low as 7°C (46°F), bed bugs die at 45°C (113°F).
    • To kill bed bugs with heat, the room must be even hotter to ensure sustained heat reaches the bugs no matter where they are hiding.
  • Almost anywhere that hosts can live is a good place to find bed bugs.
  • In tropical and subtropical areas, tropical bed bugs (Cimex hemipterus) require a higher average temperature than the common bed bug.

How To Kill The Hidden Bed Bugs?

However, using alcohol on a mattress can leave it stained and smelling of alcohol.

410°F is the temperature produced by steam cleaners.
You can kill bed bugs, their eggs, and nymphs with a steam cleaner on soft furnishings like mattresses and couches.
It’s not recommended to use bug bombs to kill minor bugs like bedbugs and fleas.
Because bug bombs have a limited reach, they do not have residual toxicity, and they do not penetrate tiny gaps in which bed bugs hide.
So, bug bombs are ineffective and can be dangerous too.
