There are primarily two types of bed bugs that infest human habitats: Cimex lectularius and Cimex hemipterus. While similar in behavior and appearance, they can be found in different regions and environments. This article will break down the characteristics and habitats of each type, helping you identify and tackle the specific bed bug infestation you might be facing.
POINTS
- There are various types of bed bugs worldwide, such as the common bed bug (‘Cimex lectularius’), the tropical bed bug (‘Cimex hemipterus’), the West African bed bug (‘Leptocimex boueti’), the Mexican chicken bug (‘Haematosiphon inodorus’), the swallow bug (‘Oeciacus vicarius’), and several species of bat bugs.
- Differentiating between various types of bed bugs based solely on appearance can be challenging without specialized knowledge or equipment due to minute physical differences. However, the type of host they prefer or the geographical region they inhabit could provide clues.
- Common signs of an infestation include bites on your skin, often in a line or clustered together, spotting tiny black fecal spots on your bed sheets, shed skins of bed bugs, or seeing the insects themselves. These signs remain largely consistent across different species.
- Control and management of bed bugs involves identifying the species, deep cleaning, heated treatment, or professional pesticide application. Knowledge about different species of bed bugs can aid in applying a more effective pest control strategy.
- A misconception is that all bed bugs are harmful to humans; in reality, while some types of bed bugs exclusively feed on humans, others primarily infest birds or bats. However, in the absence of their primary host, these bugs could resort to feeding on humans.
The Most Common Types of Bed Bugs
How Many Types of Bed Bugs Are There Globally?
Globally, there exist over 90 species of bugs identified under the family Cimicidae, but fortunately, only a handful of these are considered a real nuisance to humans. When you think of bed bugs, you’re most likely thinking of ‘Cimex lectularius,’ the most prevalent species attacking our homes. However, there are several other types of bed bugs that may not be as well-known.
What Are the Most Common Types of Bed Bugs?
Understanding the most common types of bed bugs can help you identify and address infestations effectively. The table below compares the key characteristics of these species, including their preferred hosts, habitats, and distinguishing traits.
Name | Host Preference | Primary Habitat | Size/Shape | Distinctive Traits |
---|---|---|---|---|
Common Bed Bug (Cimex lectularius) | Humans | Homes in temperate climates | Small, flat, oval | Highly adaptable to various environments. |
Tropical Bed Bug (Cimex hemipterus) | Humans | Tropical and subtropical regions | Larger, wider prothorax | Thrives in warm, humid areas. |
West African Bed Bug (Leptocimex boueti) | Humans, birds | West Africa, South America | Elongated body | Often found in bird roosts or homes. |
Mexican Chicken Bug (Haematosiphon inodorus) | Birds (especially chickens) | Poultry farms, bird habitats | Larger, oval | Can transmit poultry diseases. |
Swallow Bug (Oeciacus vicarius) | Birds (swallows) | Swallow nests | Small, flat, oval | Can lie dormant for extended periods. |
Bat Bug (Cimex pilosellus) | Bats | Bat roosts | Similar to common bed bugs | Longer fringe hairs on thorax. |
These are the key players in the hide-and-seek game that bed bugs love to play with humans. As you go further into this article, you will learn more about the different types, their physical characteristics, feeding preference, and geographical distribution.
Understanding the Different Types of Bed Bugs
1. Common Bed Bug (Cimex lectularius)
What Is the Cimex lectularius, or the Common Bed Bug?
The Cimex lectularius, commonly called the common bed bug, is the most prevalent species found in homes worldwide. Below is a breakdown of its key characteristics and behaviors to help you recognize and address infestations effectively:
- Size: Small, about 0.2 inches (5–7 mm) in length when fully grown.
- Shape: Flat, oval body that expands after feeding, appearing more rounded.
- Color: Reddish-brown, with a more vibrant hue after a blood meal.
- Habitat: Found worldwide, especially in temperate climates and urban areas.
- Activity Pattern: Nocturnal; hides in cracks and crevices during the day and feeds at night.
- Diet: Feeds exclusively on the blood of humans and warm-blooded mammals.
- Bites: Causes itchy, red welts often clustered in lines on exposed skin.
- Health Impact: May lead to skin rashes, allergic reactions, and psychological stress.
- Adaptability: Extremely resilient; can survive for months without feeding in adverse conditions.
The ‘Cimex lectularius,’ also known as the common bed bug, is the type that keeps pest control businesses thriving. This star player in the bed bug family has a worldwide presence, although it’s a bigger fan of temperate climates over tropical regions. The common bed bug is renowned for its adaptability and seems to have a knack for surviving various climates and environments, which is bad news for us.
2. Tropical Bed Bug (Cimex hemipterus)
Meet the tropical cousin of the infamous common bed bug, the ‘Cimex hemipterus,’ also known as the tropical bed bug. As the name hints, this species thrives in tropical and subtropical regions. Its distinctive feature is its larger built compared to the common bed bug and a wider prothorax.
Much like its relative, the tropical bed bug also loves indulging in a good feast on human blood, especially when we’re deeply off in dreamland. Consistent with other bed bugs, its bites can lead to a range of skin irritations and allergies.
3. West African Bed Bug (Leptocimex boueti)
The ‘Leptocimex boueti,’ commonly known as the west African bed bug, is another member of this notorious family. As you’ve probably guessed from the name, this type of bed bug is native to West Africa and South America. This bug, though smaller than the common bed bug, has a more elongated body.
Although the West African bed bug feeds on human blood much like its notorious bed bug cousins, it’s not commonly present in human homes. These bugs are often found infesting common roosting places for birds like pigeons, which are their primary food source.
4. Mexican Chicken Bug (Haematosiphon inodorus)
The ‘Haematosiphon inodorus,’ known as the Mexican chicken bug, is a bed bug variant you’ll typically find infesting birds, particularly chickens. Primarily found in North America, these bugs are larger than common bed bugs and can transfer several types of poultry diseases, leading to significant monetary loss in the chicken industry.
While their preference is birds, a lack of meals can drive them to bite humans. However, compared to their notorious cousins, Mexican chicken bugs are not typically a major concern for household infestations.
5. Swallow Bug (Oeciacus vicarius)
The ‘Oeciacus vicarius,’ colloquially known as the swallow bug, is a unique member of the bed bug family. Although this insect comes from the same family as the infamous bed bug, it primarily targets not humans, but birds – specifically swallows.
Swallow bugs are named after their preferred hosts – swallows. Especially prevalent in swallow nests, these bugs will wait until the birds return to their nests and then emerge to feed on their blood. When their bird hosts migrate and leave the nests temporarily empty, swallow bugs can survive without a meal for quite an extended period, lying dormant until the birds return.
Swallow bugs share a strong resemblance with common bed bugs, having a similarly small, flat, oval-shaped body. But, unlike their notorious relatives, these bugs typically aren’t a high concern for humans. However, in absence of their usual hosts, they may bite humans if they come into contact.
6. Bat Bugs
Rounding out our list, we have the ‘Bat Bugs’, which is a collective term used for bed bugs that primarily infest bats, and their most common types are ‘Cimex pilosellus’ and ‘Cimex pipistrelli.’ Just like every other member in the bed bug family, bat bugs are parasites that feed on the blood of warm-blooded animals – in this case, bats.
Bat bugs share a striking physical resemblance with the common bed bug, often leading to misidentification. They are typically about the same size as common bed bugs and have the same flat, oval shape. However, bat bugs can be differentiated by their longer fringe hairs on the upper covering of their thorax.
These bugs are generally found in places where bats roost, such as attics and belfries, clinging onto the bat’s body and feeding on their blood. While bat bugs primarily prefer bats, if their host becomes unavailable – say during winter hibernation – they can and will resort to feeding on other warm-blooded hosts, including humans.
Now that we’ve met the ‘pest-y six,’ let’s delve into some their physical characteristics that help in differentiating them.
The Physical Characteristics of Different Bed Bugs
How Do the Sizes of Different Types of Bed Bugs Vary?
Bed bugs vary in size depending on their species, with some being slightly larger or more elongated than others. The table below provides a comparison of the sizes of different bed bug types, including distinctions between adults and nymphs:
Species | Adult Size | Nymph Size | Notable Variations |
---|---|---|---|
Common Bed Bug (Cimex lectularius) | 0.2 inches (5–7 mm) | 0.06–0.12 inches (1.5–3 mm) | Compact, oval body that expands significantly after feeding. |
Tropical Bed Bug (Cimex hemipterus) | Slightly larger than 0.2 inches | 0.08–0.14 inches (2–3.5 mm) | Wider prothorax; more robust appearance. |
West African Bed Bug (Leptocimex boueti) | 0.16–0.2 inches (4–5 mm) | 0.05–0.1 inches (1–2.5 mm) | Elongated body compared to other species. |
Mexican Chicken Bug (Haematosiphon inodorus) | 0.24–0.28 inches (6–7 mm) | 0.1–0.14 inches (2.5–3.5 mm) | Larger than most bed bugs; oval and slightly flattened. |
Swallow Bug (Oeciacus vicarius) | 0.16–0.2 inches (4–5 mm) | 0.06–0.1 inches (1.5–2.5 mm) | Small, flat body adapted for hiding in bird nests. |
Bat Bug (Cimex pilosellus) | 0.2 inches (5–7 mm) | 0.06–0.12 inches (1.5–3 mm) | Similar in size to Cimex lectularius but with longer fringe hairs. |
How Are Different Bed Bugs Similar and Different in Physical Appearance?
Regardless of the type, most bed bugs share similar physical traits – they are tiny, oval insects with flat bodies. However, the West African bed bugs stand out from the crowd a bit with their more elongated bodies compared to their counterparts.
How Can You Differentiate Between the Different Types of Bed Bugs?
Unless you’re an entomologist equipped with a microscope, it may be difficult to distinguish between the different types of bed bugs based solely on appearance. This is because the differences in their physical qualities are pretty minute and subtle. However, their geographical presence and the environment they inhabit might provide a clue about their identity. For instance, if you’re in a tropical region and find a larger specimen, it could very well be a tropical bed bug.
Bed Bug Identification
What Do Different Types of Bed Bugs Look Like?
Different types of bed bugs do have subtle physical differences, but for a layman, it’s hard to tell them apart based solely on their looks. Broadly, they have small, flat bodies shaped like an oval, and when they haven’t fed, appear more or less reddish-brown. The younger bed bugs, known as nymphs, or baby bed bugs, are almost colorless, rendering them more difficult to identify. Explore further to understand in detail what bed bugs look like.
Can the Different Types of Bed Bugs Be Distinguished Without a Microscope?
To effectively distinguish between different bed bug types, a microscope is required due to the minute physical differences. However, their location or the animal host they are found on can guide you to their possible species, for example, the Mexican chicken bug found on birds.
Habitat and Feeding Patterns
What Types of Hosts Do Different Bed Bugs Prefer?
Different bed bug species have varying host preferences, ranging from humans to birds and bats. The table below outlines the primary and secondary hosts for each species, helping you understand their feeding habits and potential habitats.
Species | Primary Host | Secondary Host | Notes |
---|---|---|---|
Common Bed Bug (Cimex lectularius) | Humans | Warm-blooded mammals | Most common in homes and urban environments. |
Tropical Bed Bug (Cimex hemipterus) | Humans | None | Prefers tropical climates and primarily feeds on humans. |
West African Bed Bug (Leptocimex boueti) | Birds, Humans | None | Often found in bird roosts; may feed on humans when birds are absent. |
Mexican Chicken Bug (Haematosiphon inodorus) | Birds (especially chickens) | Humans (rarely) | Common in poultry farms; feeds on humans only when bird hosts are scarce. |
Swallow Bug (Oeciacus vicarius) | Birds (swallows) | Humans (occasionally) | Found in swallow nests; may bite humans if bird hosts are unavailable. |
Bat Bug (Cimex pilosellus) | Bats | Humans (rarely) | Primarily roosts with bats but may infest attics or human spaces. |
Are There Bed Bugs That Are Specific to Certain Geographical Regions?
Some bed bug species are more commonly found in specific geographical regions due to their adaptability to certain climates and environments. The table below highlights the species, along with their common names, and the regions where they are predominantly found.

Common Bed Bug (Cimex lectularius) | Worldwide | Temperate climates | Found in homes, hotels, and urban areas globally. |
Tropical Bed Bug (Cimex hemipterus) | Tropical and subtropical regions | Warm, humid climates | Common in Asia, Africa, and parts of South America. |
West African Bed Bug (Leptocimex boueti) | West Africa, South America | Tropical climates | Often found in bird roosts; less commonly in human habitats. |
Mexican Chicken Bug (Haematosiphon inodorus) | North America | Arid and temperate climates | Typically infests poultry farms and bird habitats. |
Swallow Bug (Oeciacus vicarius) | North America | Moderate climates | Found in swallow nests across the U.S. and Canada. |
Bat Bug (Cimex pilosellus) | Worldwide (where bats roost) | Varies with bat roosting sites | Adaptable to climates where bats are present. |
What Are the Distinctions Between Household Bugs and Other Types of Bed Bugs?
- Primarily, household bugs such as the common bed bugs thrive in close proximity to human residences since humans are their preferential hosts.
- Other types of bed bugs, like the Mexican chicken bug, are more likely to infest birds and poultry houses.
These distinctions in habitat preferences are a key factor in controlling and preventing infestations.
Bed Bug Species Beyond the Commonly Known
Are There Different Species of Bed Bugs?
Yes, there are many species of bed bugs. However, most of these species prefer an animal host and are not commonly found in human dwellings. Only a handful, like our ‘Cimex lectularius’ and ‘Cimex hemipterus,’ regularly infest human habitats.
What Are Some Lesser-Known Types of Bed Bugs?
Apart from the commonly known species, there are other species like the ‘Cimex pilosellus’ and ‘Cimex pipistrelli’ which primarily affect bats and occasionally human dwellings. More studies are needed to gain a better understanding of these species and their behavior.
What Is the Cimicidae Family, and How Is It Related to Bed Bugs?
The Cimicidae family is a group of insects which includes all the bed bugs we’ve discussed so far. This family is characterized by small wingless insects that feed on the blood of warm-blooded hosts. If you find a bed bug, know that it falls under the Cimicidae family, regardless of the species.
Encounters with Bed Bugs in Domestic Spaces
Are There Different Types of Bugs Found in Beds?
While ‘bed bugs’ might imply a single type of bug, in reality, the kind of bugs found in beds can vary. In addition to common bed bugs, there may also be ticks, fleas, or other types of mites sharing your bed.
What Other Types of Bugs Can Be Mistaken for Bed Bugs in Houses?
Many bugs resemble bed bugs, making it challenging to distinguish them without close inspection. The table below highlights common bugs often mistaken for bed bugs, along with their identifying features and differences.
Bug Type | Appearance | How It Differs from Bed Bugs | Common Habitat |
---|---|---|---|
Carpet Beetles | Small, round, and often multicolored (black, white, yellow). | Covered in tiny hairs; does not bite or feed on blood. | Carpets, furniture, and fabrics. |
Booklice | Tiny, pale white or light brown, with soft bodies. | Much smaller than bed bugs; feeds on mold and fungi. | Damp areas, bookshelves, and wallpaper. |
Bat Bugs | Nearly identical to bed bugs but with longer fringe hairs on thorax. | Found in areas with bats; feeds on bats primarily. | Attics, bat roosts, and nearby walls. |
Spider Beetles | Round, reddish-brown, resembling small spiders. | Longer legs and antennae; feeds on grains and stored food. | Kitchens, pantries, and storage areas. |
Fleas | Tiny, dark, wingless, and capable of jumping. | Jumps when disturbed; bites are clustered on ankles. | Pet bedding, carpets, and upholstery. |
Cockroach Nymphs | Small, oval, and reddish-brown. | Moves quickly; does not cluster near beds. | Kitchens, bathrooms, and crevices. |
Can Bed Bugs Be Confused with Bed Mites or Beetles?
Absolutely, bed bugs often can be confused with other tiny pests like bed mites, carpet beetles, or even bat bugs due to their similar size and coloring.
What Are the Types of Bed Bug Mites and How Are They Related to Bed Bugs?
While bed bugs and mites share similar habitats, they differ significantly in their biology and behavior. The table below compares bed bug mites (such as dust mites) with bed bugs to clarify their distinctions and relationship:
Feature | Bed Bugs | Bed Bug Mites (e.g., Dust Mites) |
---|---|---|
Diet | Feeds on the blood of humans and warm-blooded animals. | Feeds on dead skin cells and organic debris. |
Size | 0.2 inches (5–7 mm) | Microscopic (0.01–0.02 inches or 0.2–0.5 mm). |
Habitat | Beds, furniture, cracks, and crevices in human dwellings. | Mattresses, carpets, and areas with accumulated dust. |
Impact on Humans | Causes itchy bites, skin rashes, and allergic reactions. | Can trigger allergies or asthma through inhalation of droppings. |
Visibility | Visible to the naked eye. | Invisible without magnification. |
Relation to Bed Bugs | Belongs to the Cimicidae family of insects. | Unrelated; belongs to the Arachnida class (spiders, ticks). |
Bed mites or dust mites are tiny creatures that commonly live in house dust. While bed bugs feed on blood, dust mites prefer flakes of human skin. These mites, although sharing a common habitat – your bed, are not related to bed bugs.
The Universal Signs of Bed Bug Infestations

West African Bed Bug (Leptocimex boueti) | Mild skin reactions if bitten | Minimal psychological impact | Rare economic costs; usually limited to bird habitats. |
Mexican Chicken Bug (Haematosiphon inodorus) | Rare bites; potential poultry disease transmission | Minimal psychological impact | Financial loss in poultry industry due to disease transmission. |
Swallow Bug (Oeciacus vicarius) | Rare bites; mild irritation | Minimal stress unless infestation is heavy | Rare financial costs; limited to bird environments. |
Bat Bug (Cimex pilosellus) | Rare bites when bats are absent | Minimal psychological impact | Minor costs for addressing bat roost clean-ups. |
While the exact impact can vary depending on species, size of the infestation, and an individual’s reaction to bites, common issues include itching and allergic reactions. Heavy infestations could also lead to sleep deprivation or anxiety stemming from knowing these pests share your bed.
Common Misconceptions About Bed Bugs
Are There Different Kinds of Bed Bugs or Is There Only One Type?
Contrary to popular belief, “bed bug” is not just one type of bug; rather, it encompasses several species belonging to the Cimicidae family.
Are All Bed Bugs Harmful to Humans or Are There Types That Are Benign?
While most bed bug species are harmful to humans due to their blood-feeding behavior, some species primarily infest animals and only bite humans in rare circumstances. The table below differentiates harmful and less harmful bed bug species, now including their common names, based on their host preference and likelihood of human interaction.
Species | Harm to Humans | Primary Host | Likelihood of Human Bites |
---|---|---|---|
Common Bed Bug (Cimex lectularius) | High | Humans | Very likely; exclusively feeds on humans. |
Tropical Bed Bug (Cimex hemipterus) | High | Humans | Very likely; prefers human blood. |
West African Bed Bug (Leptocimex boueti) | Moderate | Birds, Humans | Occasionally bites humans when birds are absent. |
Mexican Chicken Bug (Haematosiphon inodorus) | Low | Birds (especially chickens) | Rare; primarily feeds on poultry. |
Swallow Bug (Oeciacus vicarius) | Low | Birds (swallows) | Rare; bites humans only when bird hosts are unavailable. |
Bat Bug (Cimex pilosellus) | Low | Bats | Rare; bites humans when bats are inaccessible. |
While some types of bed bugs exclusively feed on humans, others prefer birds or bats. So not all species are harmful to us, but when their primary host is unavailable, they could find humans to be a feasible alternative.
