Bed bugs are tiny little creatures which can make your favourite hobby, sleep, a disaster. Let us now find out what does a bed bug look like and how you can get rid of it.
What Does a Bed Bug Look Like?
Bed bugs have been known to human beings for thousands of years now, they are nocturnal parasites that feed on human blood.
Two species of bed bugs are the common cause of human infestations: Cimex lectularius and Cimex hemipterus. These ‘shy’ bugs are known for hiding during the daytime in dark places.
Hiding places of bed bugs include mattress seams, bed sheet seams, bed frames, seams of curtains, upholstered furniture, fabric folds, and even cracks in the wall.
Controlling bed bug infestation is difficult as the bed bugs breed at an enormous rate, and even the hatchlings are known to feed on human blood. But what does a bed bug look like?
1. Evolution of Bed Bugs
Before delving into what does a bed bug look like, let’s explore some background.
The modern-day bed bugs are known to have emerged around 115 million years ago, even before human evolution commenced. At that time, the bugs (bat bugs) were parasites known to feed on bats which were assumed to be their initial host.
It is believed that the bat bugs further evolved to specialize in feeding on birds and bats. With time, they evolved to feed on warm-blooded animals. It is also believed that the bed bugs may not have split their lineage to evolve into human-specific but would have evolved into one.
2. Particulars: What Does a Bed Bug Look like
Bed bugs are tiny crawling insects, adult bed bugs are usually 4-6 mm in length, about the size of an apple seed. A fully grown bed bug looks similar to cockroach nymphs.
The colour of these bugs varies from light brown to dark brown or red, depending upon the stage of development.
Adult bed bugs have flat bodies, these six-legged bugs are quick and are known for their ability to hide.
The oval-shaped bodies have vestigial front wings, which are now only pad-like structures. The bugs shed their skin by discarding their outer exoskeleton during each advancement in their life stages.
The eggs of bed bugs are of size 1-2 mm, and the colour is akin to pearl white. The newly hatched hatchlings, called the bed bug nymphs, are translucent or whitish-yellow and gain colour as they mature.
So what does a bed bug look like? The bed bugs’ appearance resembles commonly seen insects such as cockroaches and booklice. In addition, these bugs have an undesirable and characteristic musty odour emitted when crushed or touched.
They usually spread by crawling from one place to another or carrying personal belongings. These bugs are easily mistaken for carpet beetles, spider beetles, fleas, cockroach nymphs or any similar small brown or reddish-brown insects.
3. Stages of Development: Bed Bug Look Like
Bed bugs are known to reproduce exponentially, with a single female bed bug laying over 10 eggs every day and over 500 eggs in its life span. These insects have a lifecycle consisting of six stages of life and last being the adult stage, where they are sexually matured and capable of reproducing.
While the bed bugs remain alive without food for about 70 days, they require at least one blood meal to advance into the next stage. In each stage, the bugs will shed skins which is their exoskeleton.
A bed bug may take several weeks to develop into a mature adult. The first stage of a bedbug is the egg. The bed bug eggs are around 1 mm and are usually visible to the naked eye. The second stage is the hatched nymphs which are the white or transparent bodies.
Upon obtaining the nutrients required for further development, these insects shed skins and move on to the next stage, where the sizes increase from 2 mm to 3 mm, which is about the size of a poppy seed.
With each stage, the skin colour darkens from white to reddish brown until the final adult stage, wherein the bed bug sizes vary between 4.5 and 6 mm. Bed bugs have oval-shaped bodies in all stages of development.
4. How do Bed Bugs Feed?
Bed bugs are bloodsuckers, and their bodies are evolved to aid them. These bugs consume blood from warm-blooded animals though they are human-specific insects.
These insects do not spend their entire time in search of their host. The bed bugs are known to hide and only leave their shelter when they are starving, and they return to their shelter when threatened due to light or once they have completed feeding.
The insects have high sensitivity to carbon dioxide, body temperature, and odour. The bed bugs are home on their host with any of the three factors. Studies have indicated that bed bugs can respond to human smell alone.
Once these bugs have detected their host, they usually approach the exposed parts of the body in darkness or dim light. The mouth of the bugs has evolved into seeing through the skin of the human and injecting anticoagulants, which are present in its saliva.
Bite of bed bugs is similar to that of flea bites. However, it is not usually painful because its saliva also consists of painkillers, which subdue the pain and thereby allow the bed bug to consume blood as much as required.
5. How do Bedbugs Infest?
Whilst hygiene cannot always be a reason for bed bug infestation, lack of hygiene may worsen the condition. The bugs attach themselves to personal belongings such as clothes and bags from an infested place and are known to spread if the infected belongings are treated before getting to living spaces.
As the bed bugs hide inside cracks in furniture and fabric folds, another source of bed bug infestation is second-hand or used furniture, including beds and mattresses.
It is important to check the furniture for termites and bed bugs before buying it. Mattresses and upholstered furniture are great sources for introducing bed bugs into one’s house.
It is easy to identify bed bug infestation. Blood stains on the bed sheets and mattresses, either due to the excretion of digested blood or the crushing of bed bugs, are the signs of bed bugs. These blood marks may be because of the crushing of bed bugs or maybe the excretion of the bedbug.
An infested wall crack will have black and brown dots all around it. In addition to bedrooms and living spaces, bed bugs infest electrical outlets where the cracks near switchboards give bed bugs perfect hiding places.
6. Effect of a Bedbug Bite
Besides the loss of blood and the feeling of itch and reddishness on the skin, bed bug bites are usually harmless. They don’t usually carry any pathogens which can spread disease. However, few people develop severe allergies and skin reactions due to bed bug bites.
The immediate symptom is inflamed spots which are itchy. A few people may develop fluid-filled blisters.
In some cases, a person may experience life-threatening reactions called anaphylaxis which is difficulty in breathing, fever, and heart issues. Bed bug bites are also known to cause psychological conditions in people.
The effects of bed bug bites are limited to the skin except in case of allergic conditions. The bed bugs’ ability to pierce and release blood-thinning substances along with painkillers results in a delay in the body’s response to the bite.
Symptoms of the bite in some cases are not evident until some days. In usual cases, the lesion size varies between 2-5 mm. The reaction to the lesion may also vary from no itching to intense itching, which may last for more than a few weeks.
Further scratching of the lesion may result in bleeding, resulting in subsequent bacterial infections if left untreated. In case an individual is allergic to bed bug bites, one may suffer from severe itchiness and other skin conditions.
Research has indicated that people may suffer from symptoms and other signs suggestive of PTSD (Post Traumatic Stress Disorder), such as hypervigilance, insomnia, nightmares, and anxiety.
In rare cases, severe bed bug incidents have been known to alter hormone balance in women. To find out how to get rid of menstrual cramps overnight, click here.

Methods of extermination of bed bugs are mentioned below:-
(a) Maintain high room temperature. Bed bugs cannot regulate their body temperature and higher room temperature results in a reduction in numbers.
(b) Wash clothes in hot water.
(c) Apply alcohol in the infested area.
(d) Kerosene can also be used in bed bug-hiding places such as bedding and mattress seams. Kerosene is also known to kill bed bug eggs.
