What Do Pennsylvania Wood Cockroaches Look Like?

Wood roaches in general, as are often confused with American cockroaches due to their similar size and color.

They also will hide in similar areas outside of your home.

That said, American cockroaches are a much bigger problem than wood cockroaches.

First, American cockroaches will infest and reproduce indoors.

Wood cockroaches, on the other hand, live outdoors. These roaches are accidental invaders and they can’t reproduce indoors. As such, Wood roaches will not infest your home.

Location

Pennsylvania wood roaches are found in the eastern, southern, and midwestern U.S states. They are also in some areas of Canada.

Size

Pennsylvania wood cockroaches grow between ¾ inch to 1 ¼ inch. Females are generally slightly smaller while males are larger.

Appearance

Pennsylvania wood cockroaches are dark brown with a yellow almost translucent margin on their thorax and wings.

Males have large wings that extend beyond their abdomen. Females have smaller wings that only cover around ⅓ of their abdomen.

Males are capable of a short period of flight, while females can not fly at all.

Behavior

Wood cockroaches prefer to live outdoors but can wander indoors in search of shelter.

They feed on decaying organic matter such as woodpiles, stumps, hollow trees, piles of leaves, mulch, dying fruit. 

Wood cockroaches are attracted to light, so you can find them near light sources around decks and backyards.

In some cases American cockroaches can grow as large as 3 inches long.

American cockroaches have a light brown ring around their head.

Both males and females have wings that extend beyond their abdomen and are both capable of flying short distances.

2. Use Traps

The best way to identify wood roaches is by using a trap.

Fortunately, it’s also the easiest way to get rid of them.

Because wood roaches don’t reproduce indoors, you can get rid of them by simply trapping them.

Place your roach trap where wood roaches are likely to be in your home.

Some ideal places are in the restroom or kitchen, where there are sources of food and water.

You can also use a roach trap to target wood roaches outdoors.

Keep in mind that traps are less effective outdoors due to the elements.

The best way to determine what type of roaches you have is to use a trap or to do an inspection.

Inspect any dead or decaying organic material, under rocks, around trash cans, near any sources of water, under mulch, or around potted plants.

These are all locations you will find wood roaches.

You can also inspect on or around sewers, on curves, near doorways, or around the structure of your home for wood and American cockroaches as well.

Identify the type of cockroach in your home based on what you see.

3. Seal All Entry Points

Pennsylvania wood cockroaches prefer to live outdoors.

They generally only travel inside your home on accident when they are searching for shelter.

If wood roaches get into your home, that typically means that you have easy entry points.

As such, the easiest way to prevent wood roaches from infesting your home is to seal up entry points.

Ensure doors and windows are correctly installed and that there are no gaps around them where wood cockroaches can enter.

Inspect and screen and ensure there are no holes or tears on them.

Weatherstrip your doors and windows to keep wood roaches from entering along the sides or top.

Use a door sweep to block the gap under your doors to prevent wood roaches from crawling in. If you don’t want to drill, you can use a door strip that sticks onto the door with an adhesive strip.

Caulk any cracks on your wall. Cockroaches can fit through the tiniest holes, so make sure to cover up even those you think they won’t fit in.

For most people, one bottle of caulk is typically sufficient to seal up and cracks and crevices around your home, and it will cost you around $10.

If you have more entry points than average, you might need two bottles of caulk.

You’re also probably experiencing infestation outside your home (we’ll address this later).

Make sure your faucets and pipes don’t have any cracks where cockroaches can slip through.

Any wood roaches inside your home won’t be able to reproduce and will eventually die.

If you do not want to wait till then, you can use sticky traps to capture them.

4. Keep Your Yard Clean

If you have a Pennsylvania wood cockroach indoors, it’s likely that you have an infestation outdoors.

The only exception is that if the cockroach hitched hiked on a piece of wood from somewhere other than outside your home.

As such, the best way to get rid of Pennsylvania wood cockroaches is by cleaning up outdoors.

Wood cockroaches eat decaying matter, sweets, and starches. Eliminating these will help get rid of them.

Remove any decaying matter such as rotting trees, leaf litter, rotting fruit, and rotting vegetables. These are the primary source of food for wood cockroaches.

Below are a few other things you can do to make your home less appealing to wood roaches

  • Store firewood and another wood object properly.
  • Keep your lawns well-maintained and free of rotting leaves or branches.
  • Seal soil, mulch, and manure in proper inside containers.
  • Use fewer lights outside or replace outdoor lights with less warm-colored LED lights.
  • Use motion detectors or timers for your outdoor lights.
  • Limit your indoor light and use curtains or blinds.
  • Fix any leaking pipes and faucets.
  • Clean gutters, vents, pipes, and window wells.

 

By making the outside of your home less appealing to wood roaches, they will eventually leave and seek other places to live.

5. Barrier Treatment

If you find that the infestation is rather large after cleaning your yard, it might be necessary to apply a pesticide to your entire yard.

Create a barrier to keep Wood Roaches out by spraying a perimeter treatment around the exterior of your house.

Spray up 2 or 3 feet around doors, windows, and the foundation.

These sprays typically last three months before needing to reapply.

If you see an improvement in the infestation over the next three months, then your next treatment may not need to be your entire yard.

Consider applying a 3 feet wide barrier of insecticide around your entire yard.

Natural Ways To Kill Wood Roaches

If you have a garden or pets, I recommend using natural pesticides to keep cockroaches out.

One of the best natural pesticides to use outside is Diatomaceous earth.

Diatomaceous earth is usually used as powder form.

But, I recommend mixing it with water for easier outdoor applications.

In a spray bottle, mix ½ cup DE (8 tablespoons) and 2 cups of water.

Spray the formula throughout your yard.

While DE doesn’t work when wet, it will once the formula has dried up.

Spray the pesticide around your doors, windows, and walls going up 2 or 3 feet.

Also, spray on any other possible entry points.

Another natural insecticide you can use in your garden is cinnamon.

Place a thin layer of cinnamon to your garden soil to repel, including cockroaches.

You’ll also want to apply a barrier around your yard and to keep wood roaches away.
