Cockroaches and water bugs may look similar, but there are key differences you can use to tell them apart easily. This article provides you with all such information.
Following the guidelines listed here, you shouldn’t have such a challenge differentiating roaches from these bugs.
Water Bug vs. Roach
The ability to tell apart a pest from other insects helps resolve the problem posed by their presence. Often, homeowners have a challenge distinguishing one insect from the other.
One of many examples is that between cockroaches and water bugs. Are you having a hard time distinguishing between the two? There’s help!
To kick-start our discussion, it’s necessary to look individually at each of these insects. Starting with cockroaches, these are scavenging insects that look similar to beetles.
Four of the most common species in the United States include the German roach, American, Oriental, and brown-banded cockroaches.
More often than not, people mistake these roaches for water bugs. A possible reason for such misidentification is their preference for damp areas.
This doesn’t necessarily place them in the same group as water bugs.
About Water Bugs
While this is a broad term used to call insects within an order, we’re more interested in one of those; the giant water bug. Also called an electric light bug, these are mostly mistaken for roaches due to their physical similarities.
The rest of our discussion will focus on telling the key differences between the two insects.
Cockroach and Water Bugs: What are the Differences
The need to differentiate between roaches and water bugs is primarily meant to help homeowners identify a pest type and know how to approach the problem.
There are identifiable differences between the two, as you’ll find out shortly.
To tell apart these two insects, we’ll be looking at key factors like size, habitats, defense mechanism (biting), physical characteristics, and mode of feeding, among others.
Let’s begin right away, starting with cockroaches.
While it’s possible to have come across roaches multiple times, it sometimes becomes confusing to differentiate these from other pests like the water bug due to their similarities.
While this may seem so on the surface, a closer look or inspection will reveal whether you’re dealing with a roach or a water bug.
Being able to differentiate isn’t difficult once you know what to look out for.
The following parameters can be of great help in identifying roaches.
Roaches do Not Live in Water
For roaches, the closest thing to water is moisture.
In other words, these scavengers prefer moist areas but do not live in water. Roaches are adaptable pests and can be found in various habitats, including wood cabinets, boxes, and other locations close to a food source.
Certain insects display some degree of self-defense when they feel threatened. In the case of roaches, it’s quite uncommon to hear about bite cases.
However, such cannot be completely ruled out, as these pests can do so under difficult situations. Do water bugs bite? You’ll learn about that shortly.
Roaches are Scavengers
Without a doubt, roaches are excellent scavengers when it comes to their eating habits. This is why a lot of homeowners often encounter roach problems.
When roaches infest a home, it’s mostly because food is abundant. Other places you’re likely to find these creatures include hospitals and restaurants.
Can Roaches Fly?
You might have noticed that roaches have wings.
While this is true, only a handful of species can fly. Plus, these pests aren’t excellent fliers. Not all roach species have wings, though.
In most situations, you won’t find young roaches with wings. These later grow.
Compared to water bugs, roaches tend to be smaller. They typically measure around ¾” to 3” long. Anything beyond this range is likely not a roach but a water bug.
One of the easiest ways to tell a roach apart from a water bug is its physical features. Although there’s a great degree of similarity, there are also differences.
Among the key distinguishing features are the long antennae, which are about the size or length of their bodies, and their legs which have lots of spines or “hairs.”
ii. Water Bugs
Identifying water bugs isn’t that difficult.
We’ve mentioned several distinguishing features of roaches. In the case of water bugs, there are certain characteristics to look out for.
These enable you to determine whether you’re dealing with a roach or water bug.
First off, water bugs are predator insects.
They pretty much prey on a wide variety of smaller insects and animals. Unlike roaches who are scavengers, water bugs actively hunt for their food.
Water Bugs will Bite.
Water bugs won’t hesitate to bite even humans when they perceive threats. You might have wondered why these bugs are called toe biters.
It’s solely due to this reason.
For the most part, water bugs live in aquatic habitats. They’re excellent swimmers and can be found in lakes or ponds. This isn’t to say you can’t find them outside of water.
However, they never go too far beyond water bodies.
Water Bugs Fly
Unlike roaches that do not fly as much, water bugs do fly. These bugs will migrate (fly) from one water body to the next during mating season.
The distinguishing feature that sets water bugs apart from roaches is their size. Water bugs are larger than cockroaches and can measure as much as 4 inches long.
The easiest way to distinguish water bugs from roaches apart from their size is their short antennae, their pointed beaks as well as piercing mouths. What more?
The overlapping wings of water bugs make them easily identifiable.
By looking out for these features, you should be able to tell a roach apart from a water bug. These parameters help with easy differentiation between these two bugs.
You should be able to act when any of these are seen around your home’s surroundings. Out of the two, roaches are most likely to infest your home.
