Bugs that look like bed bugs in New Berlin, WIBed bugs are notorious for their ability to infest our homes, causing discomfort and distress to anyone unfortunate enough to encounter them. Identifying these blood-sucking pests is crucial for effective pest control. For the most part, bed bugs are often seen clustered together in their hiding spots—seeing them on your mattress or mattress tag is, of course, the most obvious indication of an infestation. However, there are several other bugs that look like bed bugs, leading to confusion among homeowners. Let’s uncover the top five most common bed bug look-alikes, to help you distinguish between the real culprits and their harmless counterparts.

Bed Bug Lookalikes

Identifying and dealing with a bed bug infestation can be a daunting task. To make matters more challenging, several insects often get mistaken for bed bugs due to their similar appearances. Understanding the key differences between bed bugs and their lookalikes is essential for effective pest control. Below, we’ll explore some of the most common bed bug impostors, shedding light on their characteristics, habits, and how to differentiate them from true bed bugs. Whether you’re facing an infestation or just looking to stay informed, this information will help you distinguish between these sneaky lookalikes and the real deal.

Bat Bugs 

Bat bugs are close relatives of bed bugs and are often mistaken for them. These tiny insects primarily feed on the blood of bats but can bite humans in the absence of their preferred hosts. Bat bugs resemble bed bugs in size and appearance, making it difficult to tell them apart without a closer inspection. Unlike bed bugs, bat bugs are more commonly found in areas where bats roost, such as attics and wall voids. 

Spider Beetles  

One of the primary reasons spider beetles are confused with bed bugs is their physical resemblance. Spider beetles, with their small, oval bodies and long, slender legs, bear a striking similarity to bed bugs, especially to the untrained eye. Found in wooden structures and near food, these beetles have much longer legs than bed bugs and are covered in hair. Unlike bed bugs, spider beetles do not bite and are more interested in feeding on your pantry items rather than human blood.  


Booklice, also known as Psocoptera, are tiny insects that infest damp and humid environments. They are known to eat the binding paste in old books which is why they are so named. While they don’t bite or pose any health risks to humans, their small size and pale color can lead people to confuse them with bed bug nymphs. Unlike bed bugs, booklice do not feed on blood and are harmless to humans. 

Carpet Beetle Larvae 

Carpet Beetles are common household pests that feed on a variety of natural fibers, including carpets, clothing, and upholstery. Carpet Beetle larvae are often mistaken for bed bugs due to their similar size and reddish-brown color, and because they are commonly discovered in bedrooms. Adult Carpet Beetles are rarely spotted inside the house, preferring to eat pollen and nectar from your garden. Additionally, Carpet Beetles do not bite humans but can cause extensive damage to household items. 


Fleas are notorious blood-feeding pests that infest both humans and animals. While they are usually associated with pets, fleas can bite humans as well. Their bites can be itchy and resemble bed bug bites, leading to confusion. Fleas are highly agile and can jump long distances, unlike bed bugs. Additionally, fleas have flattened bodies from side to side, allowing them to move easily through the fur of their hosts.
