Ground Beetle


Beetles That Look Like Roaches

One beetle commonly mistaken for a cockroach is the ground beetle.

These insects are often found outdoors under stones, logs, and other hiding places.

Some ground beetles are attracted to indoor lights, potentially leading homeowners to believe that they have a cockroach infestation.

Another beetle species often confused with cockroaches is the larder beetle.

Adult larder beetles are dark brown, oval-shaped, and have a cream to yellow-colored band across their wing covers.

While not as common indoors as cockroaches, larder beetles can still become a nuisance in homes if not properly identified and managed.

Distinguishing Features of Beetles and Roaches

Body Shape

Beetles and roaches have different body shapes. Beetles generally have a more rounded and oval-shaped body, like the Cigarette and Drugstore Beetle, while cockroaches exhibit a flatter and more elongated shape.


  • Beetles: Usually have clubbed or sometimes thread-like antennae
  • Cockroaches: Possess long and thin, often filamentous antennae


In terms of wings:

  • Beetles: Hard, protective front wings called elytra, covering their back wings
  • Cockroaches: Two sets of wings with leathery front wings called tegmina


  • Beetles typically move slower due to their sturdy, armored body
  • Cockroaches are known for their swift and agile movement

Here’s a summary of the physical differences:

Feature Beetles Cockroaches
Antennae Clubbed/thread-like Long and thin
Wings Elytra Tegmina
Body Shape Rounded/oval Flat/elongated
Movement Slower Swift and agile


Common Beetle Species That Resemble Cockroaches

Ground Beetles

Ground beetles are one of the most common beetle species found in North America. They are:

  • Dark-colored
  • Oval-shaped
  • Often mistaken for roaches

Click Beetles

Click beetles are named for the clicking sound they make when they flip themselves upright. They are:

  • Long and narrow
  • Tapered at both ends
  • Click sound is mistaken for a roach


Click Beetle


Long-Horned Beetles

Long-horned beetles are characterized by their lengthy antennae. They are:

  • Usually elongated
  • Medium to large in size
  • Attracted to lights at night

Long-horned beetles can be mistaken for roaches due to their size and nocturnal behavior.

Carpet Beetles

Carpet beetles are small, oval-shaped insects that can be mistaken for small cockroach nymphs. They have:

  • Varied patterns and colors
  • Feed on natural fibers
  • Invade homes and damage textiles

Roach Lookalike Insects and Bugs

June Bugs

June bugs, also known as May beetles, are commonly mistaken for roaches due to their brown color and oval shape. However, they are smaller in size and have distinguishable wings.

  • Size: 0.5-1 inch
  • Color: Brown
  • Wings: Present

Crickets resemble roaches with their flat, elongated bodies and long antennae. They differ in their size, color, and the presence of hind legs.

  • Size: 0.5-1 inch
  • Color: Brown or black
  • Legs: Strong hind legs for jumping


Camel Cricket


Water Bugs

Water bugs, also called giant water bugs, are often mistaken for roaches due to their similar size and flat, oval-shaped bodies.

These aquatic insects can grow larger than common roaches and have front legs adapted for capturing prey.

  • Size: 0.75-4 inches
  • Color: Brown or black
  • Legs: Front legs for catching prey


Giant Water Bug



Earwigs might be mistaken for roaches because of their similar body shape and color. Nonetheless, they are easily distinguishable by the pincer-like cerci at their abdomen’s end.

  • Size: 0.5-1 inch
  • Color: Brown or black
  • Cerci: Pincer-like appendages






Termites might be confused with roaches due to their general body shape. However, they have a straight waist and straight antennae, unlike the common roach.

  • Size: 0.25-0.5 inch
  • Color: Creamy white to dark brown
  • Antennae: Straight




Insect Size Color Key Feature
June Bug 0.5-1 inch Brown Wings
Cricket 0.5-1 inch Brown or black Hind legs
Water Bug 0.75-4 inches Brown or black Prey-catching legs
Earwig 0.5-1 inch Brown or black Pincer-like cerci
Termite 0.25-0.5 inch Creamy white to dark brown Straight antennae

By being aware of these differences, you can identify and address any insects that look like roaches but are actually beetles or other bugs.

Pest Control and Prevention

Identifying Infestations

To identify beetle infestations, look for signs such as:

  • Small, brown, or black insects resembling roaches
  • Damaged materials like carpets, wood, or food items
  • Larvae or shed skin around the infested area

Regular inspections help detect problems early. Keep an eye out for dermestid beetles and wood-boring beetles.

Professional Pest Control Options


Bug Control Recommendation Tool

What type of pest are you dealing with?

How severe is the infestation?

Do you require child/pet/garden safe treatments (organic)?

Are you willing to monitor and maintain the treatment yourself?

Health Risks and Other Concerns

Disease Transmission

Despite their visual resemblance, beetles and roaches are different in terms of health risks.

While roaches are well-known for carrying diseases such as salmonella, diarrhea, dysentery, and cholera, beetles typically do not transmit these diseases.

However, they may still cause concerns due to their contamination of food products or the potential for allergic reactions.

Impact on Crops

Beetles and roaches also differ in their impact on crops:

  Beetles Roaches
Crop Damage Can harm various crops, especially when they occur in high numbers Primarily a household pest, not usually a concern for crops
Examples Blister beetles found in hay can be dangerous for livestock in large amounts1 Concentrate on residential areas, often in urban settings2

Beetles can have a significant impact on agriculture, such as the bark beetle, which has ravaged tens of thousands of square miles of woodlands3.

Roaches, on the other hand, focus on human dwellings, and are less of a concern to the farming industry.


  • Beetles can damage crops and cause potential health concerns by contaminating food products.
  • Roaches are known to carry diseases and are more likely to be found indoors.
  • The impact of beetles on agriculture can include harming crops and causing issues for livestock.



Habitats and Diets

Natural Habitats of Beetles and Roaches

Beetles are a diverse group of insects inhabiting various habitats, ranging from land to aquatic environments. They can be commonly found in:

  • Forests
  • Gardens
  • Ponds
  • Lakes
  • Rivers

Roaches, on the other hand, are insects preferring warmer and moist environments, often inhabiting:

  • Upholstered furniture
  • Kitchen appliances
  • Wall voids
  • Sewers
Habitat Beetles Roaches
Forests Yes No
Gardens Yes No
Ponds, lakes, and rivers Yes No
Indoor Occasional Common

Feeding Habits

Beetles exhibit a range of diets, including:

  • Vegetarian
  • Predatory
  • Decomposers

For example, some beetles like ladybugs are predators that feed on aphids, whereas others like dung beetles consume animal feces.

The larder beetles feed on stored food products, which could lead to an infestation if not controlled.

Roaches are known to be scavengers with a diverse diet, often consuming:

  • Human food
  • Dead insects
  • Paper
  • Leather

In summary, beetles have a wide range of habitats and diets, whereas roaches prefer warm, moist environments and have a more diverse and opportunistic feeding habit.


Beetles and cockroaches, while often mistaken for one another, exhibit distinct differences in appearance and behavior.

Several beetle species, such as ground beetles, larder beetles, bess beetles and Palo Verde beetles, can be confused with roaches due to their similar appearance.

Key distinguishing features include body shape, antennae structure, and wing characteristics.

Beetles typically inhabit diverse environments, from forests to aquatic areas, and have varied diets. In contrast, roaches prefer warm, moist environments and have a broader diet.

Recognizing these differences is essential for accurate identification and appropriate pest management.
