In fact, there are numerous bugs that look similar to cockroaches, often causing confusion and panic for those who come across them. In this article, we’ll dive into the world of critters that may be mistaken for cockroaches, arming you with the knowledge to accurately identify them.
Some of these bugs imitate the appearance of cockroaches due to their similar color, size, and shape. Knowing the distinctions between these insects and cockroaches can save homeowners unnecessary stress as well as time and effort spent on extermination efforts. Keep reading to learn more about the bugs that look like cockroaches and how to tell them apart.
Common Bugs that Look Like Cockroaches
Water Bugs and Giant Water Bugs
Water bugs and giant water bugs, often mistaken for cockroaches due to their similar appearance, can be differentiated by their habitat and size. Water bugs, prefer moist and dark environments, while giant water bugs are aquatic insects found in ponds or slow-moving waters.
Features:
- Water bugs: dark brown color, oval body shape, about 1 inch long, a pair of strong forelimbs for catching prey
- Giant water bugs: up to 4 inches long, elongated body, light brown color, powerful jaw for catching prey
Crickets and Palo Verde Beetles
Crickets and Palo Verde beetles are often confused with cockroaches, but can be distinguished by size and habits. Crickets are smaller, nocturnal insects, typically found outdoors, while Palo Verde beetles can grow up to 3 inches long, feed on tree roots, and are attracted to lights at night.
Characteristics:
- Crickets: brown, black, or green color, large back legs for jumping, long antennae, chirping sounds
- Palo Verde beetles: dark brown or black, strong jaws, spiked antennae, large size
Oriental and German Cockroaches
Oriental cockroaches and German cockroaches are two common cockroach species. Oriental cockroaches are darker and larger, while German cockroaches are smaller and have dark stripes on their heads.
Comparison:
| Feature | Oriental Cockroach | German Cockroach |
|---|---|---|
| Size | 1 to 1.25 inches | 0.5 to 0.625 inches |
| Color | Dark brown to black | Tan to light brown |
| Stripes | None | Dark stripes on head |
Termites and Ants
Termites and ants, both resembling cockroaches, have different body structures and habitats. Termites feed on wood, while ants prefer sweet foods and nesting in various environments.
Identifiable Features:
- Termites: broad waist, straight antennae, wings equal in length
- Ants: narrow waist, bent antennae, different sized front and hind wings
Bed Bugs and Earwigs
Bed bugs and earwigs, though similar to cockroaches, are much smaller and exhibit unique features. For example, bed bugs are small, flat, and reddish-brown, while earwigs have elongated bodies and noticeable pincers.
Characteristics:
- Bed bugs: oval, flat, reddish-brown, less than 0.25 inches long, life cycle includes different stages and sizes
- Earwigs: long, slender body, dark-brown color, forcep-like pincers at the end of abdomen
June Bugs and Click Beetles
June bugs and click beetles, often mistaken for cockroaches, can be differentiated by their hardened wing-covers or flattened bodies. June bugs are nocturnal beetles attracted to lights, while click beetles get their name from the clicking sound they make when flipping over.
Features:
- June bugs: green or brown metallic color, stout rounded body, nocturnal habits
- Click beetles: elongated, flattened bodies, brown or black, clicking mechanism
Carpet Beetles and Wood-Boring Beetles
Carpet beetles and wood-boring beetles, although similar in appearance, have distinct habits and habitats. Carpet beetles are primarily indoor pests, feeding on fabric and other materials, while wood-boring beetles are known to damage wooden structures.
Characteristics:
- Carpet beetles: oval bodies, small size, varied colors and patterns, feed on fibers
- Wood-boring beetles: cylindrical body shape, range of sizes, long antennae, tunnel through wood
Identifying Features of Bugs and Cockroaches
Size and Color
- Cockroaches: Typically 0.7 to 3 inches, dark brown or reddish-brown.
- Bugs: Vary in size and color, depending on the type of bug.
Both cockroaches and other bugs have diverse size and color ranges. For example, German cockroaches are usually 0.5 to 0.6 inches long and light brown.
Antennae and Wings
| Feature | Cockroaches | Bugs |
|---|---|---|
| Antennae | Long, thread-like | Vary in length & shape |
| Wings | Membranous or absent | Some have, some don’t |
Cockroaches have long, thread-like antennae while other bugs may have varying antennae shapes. For instance, beetles have shorter, clubbed antennae.
Behavior and Habitat
Cockroaches:
- Nocturnal: prefer dark places.
- Moisture-loving: often found in damp environments.
For example, American cockroaches are commonly found in sewers. Bugs, on the other hand, can differ in behavior and habitat.
Health Concerns and Prevention
Diseases and Allergens
Cockroaches are known to carry various diseases and allergens. For example, they can potentially spread food-borne pathogens such as E. coli and Salmonella. Additionally, their feces, saliva, and shed skin can trigger asthma and allergic reactions.
Some ways to reduce allergens from cockroaches include:
- Regular cleaning
- Vacuuming with a HEPA filter
- Sealing food in airtight containers
Cockroach Infestations
Cockroach infestations are common, especially in schools and other public spaces. There are various types of cockroaches, such as the German cockroach, which is the most prevalent in the United States. Preventing infestations is crucial for maintaining a healthy environment.
Some prevention methods include:
- Regular inspections
- Proper sanitation
- Sealing cracks and gaps
Pros and cons of common prevention methods:
| Method | Pros | Cons |
|---|---|---|
| Chemical pesticides | Effective | Health hazards |
| Traps | Non-toxic | Less effective |
| Natural repellents | Eco-friendly | Limited scope |
Remember, a combination of these practices can help keep cockroach populations under control and maintain public health.
Control and Detection Methods
Sticky Traps and Insecticides
Sticky traps are an effective method for detecting and capturing pests that resemble cockroaches, such as waterbugs, and actual cockroaches. To use, simply place the traps in areas where these insects may be present, such as kitchens, bathrooms, and basements.
Insecticides can also be utilized to address infestations, but it’s essential to select a product specifically made for the targeted pest. Always follow the directions on the insecticide label for the best results.
Features of sticky traps:
- Easy to use
- Non-toxic
- Requires occasional replacement
Features of insecticides:
- Effective for eliminating pests
- Chemical composition
- Requires caution during application
Pros and Cons of Sticky Traps vs. Insecticides
| Method | Pros | Cons |
|---|---|---|
| Sticky Traps | Non-toxic, easy to use | Need replacement, less effective for large infestations |
| Insecticides | More effective for treating large infestations | Can be toxic, requires specific selection and careful usage |

This is a female of an introduced (but not pest) species of European wood roaches, Ectobius pallidus. They can get into houses, but will not thrive there.
Up to now, I do not acquire enough and accurate information about these cockroaches.But i think these are not new species. anyway, i’m still hoping to get some information from the experts worldwide through internet.
Ahoy, do you still need the identification of these cockroaches? where in Lanao del Norte did you collect them.
ok, aren’t there any way to contact the person who initially submitted these images?
Salamat.
Only if the person happens to check back on their posting. We do not maintain records of contact information. Sorry.

1, 2, 3 = Ergaula possibly capucina, though there are a few speciesin the region e.g. pilosa
4, 5 = Periplaneta sp.
Thanks for the IDs Darren.

I have not encountered any article stating that E. pilosa is present in the country. though it may be possible since the distribution of the species is around Indonesia (Sumatra); Malaysia (Malacca state); Indonesia (Java Island); Borneo Island. What is present in the country (esp. Luzon) is E. carunculigera.
For the Blattidae, am working with few samples of somewhat same (morphologically) and identified it not as “Periplaneta” sp. but more of the “Dorylaea” sp.

In the last month I have killed 2 roach like similar to the one in the photo from NJ. Except they are not what I would identify as German roach and these fly. They actually have wings and fly. The two killed look exactly like the photo but have wings that seem to be smaller than you would expect. They do not fly for long distances probably no more than 2 feet, but boy they are fast. Now I have one I found dead this morning that apparently expired due to exterminator spray. As everyone know the south has a real problem with roaches because of the ideal climate for breeding. I wonder if this insect is a new introduced species?
hey Im a BSbiology student too and we are writing a thesis about cockroaches in the philippines, specifically in luzon only. Can i ask the scientific names of the most common household cockroaches here? thanks a lot
That sounds like exactly the kind of thesis research you should be conducting yourself.
There are a lot of references that will lead you to that answer. If, for some very unimaginable reason you still fail to find it, look for cristian at the Museum of Natural History at UPLB
Your stories have the best titles.
That a cockroach!!! It bring germs along with it.
Some sort of roach nymph perhaps?
We wouldn’t rule that out. At first glance, the body resembles a True Bug, but mouthparts and antennae are not right.
I found a female Tuckestan roach. I think I also saw a male, it looks like the female but with wings. Does it bites? They look like they came from space. My husband was in the Army, I guess they came with him years ago.
I just discovered my 7 lb dog hunting a nearly 4 inch (it gets bigger every tI me I think of it brown beetle she bug with wings, very elongated. Thankfully it was on its back and not able to flip over or I might have failed Ted or had a heart attack or both. Worse still, it was squeaking. I lived in Venezuela for 3 years and this thing rivaled almost anything I saw there, except for the poisonous centipedes. WHAT IS IT? And more importantly, why ME? My husband saw one a few days ago at the far end of the house. It’seems been extremely hot and humid here in NJ for 2-3 weeks. How do these things even get in the house? I’m 64 and I’ve never seen anything like it. Your help is appreciated and no, I didn’t get a picture but it didn’t look like a cockroach. I live in the country. Thank you
Perhaps it was a Broad-Necked Root Borer.
Nymph of Hemithyrsocera histrio
Thanks for all the Cockroach Identifications.
It carries its egg case just like Blatella. Then I searched the closest of Blatella with black body and red legs, and it is Ischnoptera deropeltiformis. May be not, cause this image in BugGuide shows black femora:
https://bugguide.net/node/view/1080779
But distribution is OK: https://bugguide.net/node/view/350628/data
And the ootheca is very similar: https://www.flickr.com/photos/i_am_subverted/5853120579/

Wow that is cool! I also enjoy your website about Brazilian insects!
Beautiful bug. the white antennae does resemble the Borneo cockroach.
