9 Key Differences Between Bed Bugs and Bat Bugs

Bed Bugs vs. Bat Bugs: What’s the Difference?Bed bugs and bat bugs are confusion species that often get mistaken for one another.

They appear similar and behave alike, which makes it hard to tell them apart. However, if you know what to look for, you can quickly identify which pest you’re dealing with.

In this article, we’ll discuss the differences between bed bugs and bat bugs, including their appearance, behavior, location, habitat, legs, size, danger, life cycle, treatment, and bites.

Appearance and Behavior

Bed bugs and bat bugs have a similar appearance, but there are a few notable differences. Bed bugs are reddish-brown in color, while bat bugs are usually a little lighter and straw-colored.

Bed bugs are a little flatter and rounder, while bat bugs are a little more elongated. Bed bugs have shorter and more robust hairs, while bat bugs have longer and more fragile hairs.

Both bed bugs and bat bugs are nocturnal, which means they come out at night to feed on their hosts. They prefer to feed on the blood of warm-blooded animals, such as humans, bats, and birds.

Bed bugs are known to infest beds, couches, chairs, and other soft furnishings, while bat bugs are more commonly found in attics, ceilings, air vents, and walls.

Location and Habitat

Bed bugs and bat bugs can be found in different locations and habitats. Bed bugs are commonly found in human dwellings, such as homes, apartments, hotels, and dormitories.

They like to hide in cracks and crevices, such as behind baseboards, under carpets, and inside electrical outlets. Bed bugs can also be found in public places, such as movie theaters, public transport, and retail stores.

Bat bugs, on the other hand, infest bat roosts and often migrate into human dwellings. They can be found in attics, ceilings, and walls of buildings that have bat infestations.

Bat bugs can easily be transferred from the ceiling or walls to the bed or floor, where they can feed on human hosts.

Legs and Size

Bed bugs and bat bugs have six legs each, but the latter have longer hind legs. Bed bugs are typically 3mm to 6mm in size, while bat bugs are 2mm to 6mm, making them slightly smaller than bed bugs.

Danger and Life Cycle

Both bed bugs and bat bugs are harmless and do not transmit any diseases to humans. However, they can cause allergic reactions in some people, characterized by itchy skin, hives, and redness.

Psychological distress is another symptom of bed bug or bat bug infestations, which can cause anxiety, depression, and insomnia. Bed bugs and bat bugs go through five life stages, including egg, nymph (five instars), and adult.

The hatching time for bed bug eggs is 6 to 10 days, while for bat bug eggs, it can take up to two weeks. Bed bugs and bat bugs require a blood meal at each life stage to progress to the next one.

Treatment and


Bed bug and bat bug infestations require professional treatment by an exterminator. The most effective treatment methods include steamers, dryers, and monitoring traps.

It’s important to note that bed bugs and bat bugs are challenging to eliminate. Even after treatment, they may return after a few weeks or months if the source of the infestation is not removed.

Bed bugs and bat bugs both bite and leave similar red, itchy spots on the skin. However, their saliva composition is different.

Bat bugs have adapted to feeding on bat blood, while bed bugs feed on human blood. As a result, some people may develop an allergic reaction to bat bug saliva.

Bat Bugs

Appearance and Behavior

Bat bugs are bed bugs’ close cousins, but they have a few distinctive features. They are slightly longer and more slender than bed bugs, with longer legs.

Bat bugs have a sharper head shape than bed bugs, which makes them better able to navigate through bat fur. They are often found in bat roosts or bird nesting sites, where they feed on the host’s blood.

Food and Life Cycle

Bat bugs primarily feed on bats’ blood, but they can also feed on humans and other warm-blooded animals. They have a life cycle similar to bed bugs, and the incubation period for their eggs can take up to two weeks.

Bat bugs can breed and lay eggs year-round if the host is available.

Danger and Treatment

Bat bugs do not pose any serious health risks to humans, but they can cause allergic reactions in some people. They are often identified when bat hosts are evicted from ceilings and walls, where bat bugs may have been hiding.

To eliminate bat bugs, the source of the infestation (the bat host) must be removed, and cracks and crevices sealed off to prevent re-entry.


Bat bug bites are similar to bed bug bites, causing red, itchy spots on the skin. Some people may develop allergic reactions due to the bat bug saliva composition.

In some cases, bat bug infestations can leave fecal staining in the area where they reside.


In conclusion, bed bugs and bat bugs are often mistaken for one another, but there are definitive differences. Bed bugs are typically found in human dwellings, such as beds and couches, while bat bugs are commonly found in bat roosts and often travel to human dwellings.

Understanding the differences between the two pests can help you take appropriate measures to eliminate them. Although both pests can cause allergic reactions and psychological distress, neither of them poses any significant health risks to humans.

Professional treatment by an exterminator is necessary to eliminate an infestation effectively. Bed Bugs:

Appearance and Behavior

Bed bugs are small, reddish-brown insects that measure less than half an inch in length.

They have a flat, oval-shaped body that allows them to squeeze into the tiniest of spaces. Despite their name, bed bugs can be found in a variety of places, including leather couches, outlets, pipes, closets, and behind moldings.

Bed bugs are nocturnal creatures and prefer to feed on human blood, although they can also bite other warm-blooded animals. They inject an anesthetic along with an anticoagulant into the skin, preventing the person from feeling the bite and ensuring that the blood flows freely.

Bed bugs can live up to a year without feeding, but they typically feed every five to ten days. Eggs are laid and hatch within one to two weeks.

After hatching, the bed bugs go through five molts before reaching adulthood.

Food and Life Cycle

Bed bugs are not known to transmit any diseases, but their bites can cause allergic reactions in some individuals.

Bites are often characterized by red, itchy spots on the skin, which can sometimes develop into a severe rash.

Although bed bugs prefer feeding at night, they can also bite during the day, making it challenging to detect them. Comprehensive treatment of bed bug infestations requires a combination of preventative measures and active pest control.

This approach includes identifying the source of the infestation, eliminating any hiding places, and thorough cleaning. Breeding sites must be removed or treated directly with insecticides, and multiple visits from a professional exterminator may be necessary.

Danger and Treatment

Bed bug infestations can cause severe psychological distress, owing mainly to their elusive nature and the stigma attached to an infested home. The impact of bed bugs on a person’s mental health can be considerable, leading to insomnia, stress, anxiety, and paranoia.

It’s essential to handle infestations as soon as possible, as delaying treatment may only compound the problem. Treating bed bug infestations can be time-consuming and costly, but it is doable with persistence and a comprehensive plan.

A comprehensive plan includes inspection and detection, non-chemical control methods, and pesticide application. Common non-chemical methods include vacuuming, heat treatment, and mattress covers.

Detection involves identifying where bed bugs are hiding, which requires a closer look into the crevices and seams of furniture, bed frames, and other potential hiding places.

Identification of Bugs

Mistaken identity is a prevalent problem when it comes to bed bugs. Often, people mistake other insects for bed bugs without realizing it, leading to misinformed decisions and wasted resources.

For example, carpet beetles, bird bugs, bat bugs, booklice, and cockroach nymphs can all be mistaken for bed bugs.

Bat Bugs vs Bed Bugs

Although bat bugs look very similar to bed bugs, they have some key differences. Bat bugs have longer and more fragile hairs and a broader head compared to bed bugs.

Additionally, bat bugs typically feed on bat hosts, while bed bugs prefer human blood. However, they can both bite humans, making it challenging to distinguish between the two without a closer look in some cases.

Other Bugs Resembling Bed Bugs

Bird bugs, also known as swallow bugs or cliff swallows, can look quite similar to bed bugs, with reddish-brown oval-shaped bodies. Latridiidae beetles have also been found to resemble bed bugs, as do booklice and cockroach nymphs.

Evolution and Family

Bed bugs belong to the family Cimicidae, with over 100 species identified worldwide. Although they are commonly associated with humans, bed bugs originated as parasites of bats and birds.

Some species of bed bugs have adapted to human hosts, with the most common being Cimex lectularius and Cimex hemipterus. In addition to these two, a less common tropical bed bug (Cimex hemipterus tropicalis) can also infest homes.


Bed bugs are common household pests that can cause significant psychological distress to those affected by their infestations. Although their bites are not known to transmit diseases, they can cause allergic reactions in some individuals.

It’s crucial to identify bed bugs accurately and seek professional pest control to effectively eliminate these pesky insects.

Conclusion and Recommendation


With so many different bugs that resemble bed bugs, it can be challenging to identify them accurately. One way to be sure is to enlist the help of an entomologist, who can differentiate between bed bugs and their lookalikes.

Additionally, homeowners can learn to identify signs of bed bugs, such as bloodstains on sheets, fecal droppings around mattress seams, and shed bed bug skins.

Prevention and Elimination

The best way to avoid a bed bug infestation is to prevent them from entering your home in the first place. Key steps include knowing what bed bugs are and where they come from, keeping your home clutter-free, regularly vacuuming carpets and upholstery, and washing linens in hot water.

If bed bugs do enter your home, it’s essential to take action to eliminate them as quickly as possible. A key step is to reduce potential bed bug attractants, such as clutter, dirty laundry, and cracks in walls or floorboards.

Thoroughly cleaning and decluttering the home can eliminate hiding spots and make it easier to spot bed bugs. If bed bugs are in your home, you can take steps to get rid of them yourself, such as using high heat or pesticides.

However, professional pest control is often the best option for eliminating bed bugs safely and effectively. It’s important to ask potential pest control companies questions about their methods, such as what kind of pesticides they use and whether their treatment is guaranteed.

In conclusion, bed bugs are a nuisance in many homes and can cause significant psychological distress. However, there are steps you can take to prevent infestations and get rid of bed bugs if they do enter your home.

Educating yourself on bed bugs and being vigilant about potential infestations can help ensure your home remains free of these pesky insects. In conclusion, bed bugs and bat bugs are common household pests that can cause significant anxiety and distress to those who suffer from their infestations.

Although their bites are not known to transmit diseases, they can cause allergic reactions and severe emotional turmoil. Identifying bed bugs accurately and taking preventative measures can help prevent infestations from occurring.

If bed bugs do enter your home, it’s essential to take quick action to eliminate them, whether through commercial pesticide treatments or DIY methods. By following these recommended steps, you can effectively manage bed bug infestations and restore peace of mind to your home.
