Understanding Bed Bugs
What are bed bugs?
Bed bugs are small, parasitic insects that belong to the family Cimicidae. They are wingless and have a flat, oval-shaped body. Adult bed bugs are about the size of an apple seed, while the nymphs (immature bed bugs) are smaller and translucent in color. These nocturnal creatures feed on the blood of humans and animals.
Their habitat and lifestyle
Bed bugs are excellent hiders and can be found in various locations within your home. They often reside in mattresses, box springs, bed frames, and furniture, especially in areas close to where people sleep. Contrary to popular belief, bed bugs can also be found in clean environments.
These insects are primarily active at night and are attracted to the warmth and carbon dioxide emitted by humans. They use their elongated mouthparts to pierce the skin and feed on blood. Bed bugs can survive for several months without feeding, making them resilient pests.
Life Cycle of bed bugs
Understanding the life cycle of bed bugs is essential in combating infestations. A bed bug undergoes an incomplete metamorphosis, meaning it goes through three main stages: egg, nymph, and adult.
A female bed bug can lay hundreds of eggs in her lifetime. The eggs are tiny, approximately 1mm in size, and are white or translucent. They are often laid in clusters in hidden crevices near their food source.
Once the eggs hatch, the nymphs emerge. Nymphs are smaller versions of adult bed bugs and go through five instars, or stages, before reaching maturity. Each nymph stage requires a blood meal to molt into the next stage.
Finally, the nymphs molt into adult bed bugs. The entire life cycle, from egg to adult, can take anywhere from four to five weeks under optimal conditions. Adult bed bugs can live for several months, depending on the availability of food and environmental conditions.
Why Do Bed Bugs Bite?
Need for survival
Bed bugs bite humans and animals to obtain blood, which is necessary for their survival and reproduction. They require regular blood meals to develop and reproduce. While bed bugs can survive for months without feeding, they are driven by their need for sustenance.
Attractors to human blood
Bed bugs are attracted to human blood for various reasons. The primary attractor is the heat and carbon dioxide emitted by humans. Bed bugs can detect these signals from a distance, allowing them to locate potential hosts.
Other attractors include body odor, sweat, and even certain chemicals found in our skin. These factors contribute to bed bugs’ preference for human blood over other potential hosts.

How Do Bed Bugs Bite?
Anatomy of their mouthpart
Bed bugs have mouthparts specially adapted for biting and feeding on blood. Their mouthparts consist of a proboscis, which is a long, tubular structure, and several needle-like stylets.
The proboscis acts as a sheath, protecting the other mouthparts when not in use. It also contains salivary glands that produce saliva, which has anticoagulant properties to prevent the blood from clotting.
Mechanism behind their bites
When a bed bug bites, it pierces the skin using its stylets and inserts them into a blood vessel to extract blood. The stylets work together, with two of them acting as sharp, pointed structures to pierce the skin, and two others serving as tubes to deliver saliva and withdraw blood.
While bed bug bites are generally painless, the saliva they inject can cause various reactions in humans, including itching, redness, and swelling.
The Science Behind Itching
What is itching?
Itching, also known as pruritus, is an unpleasant sensation that triggers a desire to scratch. It is a common symptom that occurs due to various causes, including insect bites like those from bed bugs.
Itching is a complex process influenced by multiple factors, including the release of certain chemicals in the skin and the activation of specific nerve fibers.
How does our body respond to external irritants?
When our body detects an external irritant, such as the saliva injected by a bed bug, it releases chemicals, such as histamines, to initiate an immune response.
Histamines are responsible for dilating blood vessels, increasing blood flow to the affected area, and triggering the sensation of itching.
Role of antihistamines in controlling itch
Antihistamines are commonly used to relieve itching caused by bed bug bites and other irritants. They work by blocking the effects of histamines, reducing inflammation, and minimizing the sensation of itchiness.
Antihistamines are available in various forms, including oral tablets, creams, and lotions. They can provide temporary relief from itching and allow the skin to heal.

Bed Bug Bites and Itches
Correlation between bed bug bites and itches
Bed bug bites are one of the primary causes of itching in individuals who have been bitten. The bites typically appear as small, red welts or clusters on the skin, often in a linear pattern.
While not everyone reacts to bed bug bites, those who do may experience varying degrees of itching. Itching is a common symptom that occurs due to the body’s immune response to the foreign substances present in bed bug saliva.
How a bed bug bite leads to itching?
When a bed bug bites, it injects its saliva into the skin to prevent blood clotting and facilitate feeding. The proteins in the saliva trigger an immune response in some individuals, causing the release of histamines and the subsequent itching sensation.
The intensity of itching can vary from person to person and may depend on factors such as the individual’s immune response, sensitivity to the bed bug’s saliva, and the number of bites.
The Signs and Symptoms of Bed Bug Bites
Physical characteristics of bed bug bites
Bed bug bites share certain physical characteristics that can help differentiate them from bites caused by other insects. Some common features of bed bug bites include:
- Small, red welts or raised bumps on the skin
- Itchy or irritated skin
- Linear or clustered pattern on the body
- Sometimes accompanied by blistering or pus-filled lesions, particularly in severe cases
How to identify if the bite is from a bed bug
Identifying the source of a bite can be challenging, as different insects can cause similar reactions on the skin. However, there are certain signs that can suggest a bed bug bite:
- Bite patterns: Bed bug bites often appear in a linear or clustered pattern, as multiple bugs tend to feed in the same area.
- Bite location: Bed bug bites commonly occur on exposed areas of the body during sleep, such as the face, neck, arms, and legs.
- Presence of bed bugs: The presence of live bed bugs, shed skins, or dark spots (bed bug fecal matter) in the vicinity of the sleeping area can indicate a bed bug infestation.
If you suspect bed bug bites, it is crucial to take preventive measures and seek professional help to address the infestation.
