Comparison Of Wood Roaches And Cockroaches (2 Differences)

In this guide of comparison of wood roaches and cockroaches, you will find the significant differences between wood roaches and cockroaches. You’ll also learn where wood roaches hide, why they enter your home, and how to eliminate them.

The wood roach is not as invasive as other roach species, such as the oriental cockroach and the German cockroach.

North American wood cockroaches are native to the continent. Wood roaches are found in all 50 states of the US. 

However, wood roaches are more common in Michigan, Iowa, Indiana, and Pennsylvania.

Wood Roach Vs. Cockroach – The Similarities

Wood roaches are sometimes confused with cockroaches. This is true. There are 4500 species of cockroaches, and the wood roach is one of them. 

The lifecycle of wood roaches is the same as that of other cockroach species. 

The wood roach lays eggs. Nymphs or baby roaches hatch from the eggs. The nymphs molt or shed their skin multiple times before they become adults.

As with other roaches, wood roaches have a similar skeleton. 

As you’ll see in the next section, they differ in size, color, behavior, food choice, and infestation locations. 

The wood roach prefers to hide and nest in places that are moist, like most other species of roaches. 

Comparison Of Wood Roaches And Cockroaches – The Differences

There are two major differences between wood roaches and other species of cockroaches. 

  1. Roaches in the woods are outdoor roaches. This means they don’t invade homes. Most other species of roaches in the US, however, are home invaders. 
  2. The wood roaches eat decaying organic matter like leaves and wood. As opposed to other home-invading roaches, these roaches are not indiscriminate eaters.

In addition to color and size, there are differences in behavior as well. 

The wood roaches are tan, and they are smaller than most cockroaches, including American and Oriental roaches. 

A male wood roach can grow up to 1 inch in length, but the female is only 3/4 to 0.75 inches long.

Their size is similar to that of German roaches. 

One interesting difference between wood roaches and other cockroaches is that wood roaches are attracted to light. 

A glowing light bulb is therefore capable of attracting wood roaches. Unfortunately, that leads to them accidentally invading your home.

The wood roaches, however, would like to move out as soon as possible once they are in. This is because they cannot breed and nest in the interior of your home.

You don’t have any food sources inside your house either. It may be possible for them to eat some crumbs from fallen food, but that isn’t sufficient to keep them alive.

When they come into contact with humans, roaches of other species tend to flee and hide. Wood roaches, however, do not. 

It’s much easier to squish a wood roach under your boots then. 

However, it’s not always wise to do so since the guts from a squashed wood roach will attract ants and other cockroaches. 

Where Do Wood Roaches Hide

Wood roaches like to hide under decaying leaves and firewood in your yard or garden.

Because of this, many people also refer to them as yard roaches.

You can also find them in mulch and gutters clogged with leaves and organic matter.

Since wood roaches feed on decaying matter, your yard and garden are an ideal hiding place for them.

During the night, the light from your porch can attract wood roaches. You might find many cockroaches scurrying around in your yard after sunset because of this.

However, there’s a catch. 

The roaches can invade wooden houses made from wood. 

The reason is that wood roaches like to live in wood. Therefore, they don’t care if it’s a wooden house or a wooden log. 

Do Wood Roaches Fly

Wood roaches do fly. However, only the males are able to fly as they have fully developed wings.

It is impossible for wood roaches to fly in the female form.  

When Are Wood Roaches Most Active

Wood roaches are most active during the winters. 

But during the mating season, which is May and June, the male wood roaches fly around a lot, creating a nuisance.

It’s during the mating season that many flying male wood roaches accidentally fly into homes.

Are Wood Roaches Bad

Wood roaches aren’t harmful or dangerous. 

You won’t have an infestation, they won’t build nests, and they won’t damage your furniture or belongings.

In addition, wood roaches do not carry any diseases since they eat nothing but filth. They also don’t bite people and pets.
