The wood roach is often thought to be its cousin, the American roach. Wood cockroaches, which can grow up to one and one-quarter inches long, prefer to eat decaying organic matter and are attracted to light, whereas most roaches run from light. Females deposit their egg capsules outdoors under old logs, stumps and firewood. There is one generation of Wood cockroaches per year and, in some cases, the life cycle takes two years.
Seal up possible entry points using an easy-to-use product called
Xcluder. It is much like steel wool, but water won't make it rust out. You can also use a pesticide product around window frames to help control cockroach entry called
D-Force HPX aerosol.
At dusk, Wood cockroach males may begin taking short flights and are drawn to porch or house lights. The Wood cockroach normal habitat is moist woodland areas but it frequently become a household nuisance because it wanders into or is carried into the house with firewood.

Woods Roach
|
Wood roaches which are also called the Pennsylvania Wood roach, do not survive indoors which is probably the best news you have read so far. They require the consistently moist environment of their natural habitats such as under wood piles or loose bark and in decaying logs. So, unless your housekeeping is way below par, the presence of wood roaches is strictly a temporary annoyance. They usually die within a few days in the house, so a call to the exterminator is probably not required.
If Wood cockroaches are found anywhere inside the home, usually they are solitary. So, it's not necessary to go looking for the mate. Wood cockroaches do not reproduce or multiply inside. Since wood cockroaches do not establish themselves indoors and their presence is temporary (a few weeks, at most) during the spring, chemical pest control measures are rarely needed.

I have seen some roachs in my house that do not have wings. A couple mostly
dead but a few alive. We have lived her for about 7 years and over the
years i would say i find about 8 or 9 dead ones a year. Maybe 2 live ones a
year. They are always on the floor and the live ones that i have found
arent affraid of light and arent hidding. However i was gone for a few
hours today and came home and on the ceiling in my bedroom i found one with
wings. This is the first time i have seen one like this in my house. My
question is, how do i determine if this is a American roach or a wood
roach? I live in ky out in a wooded area and we have cattle. It has been
raining alot here too. Also how do you tell a baby american roach from a
baby wood roach? I just assumed that because most of the ones i found were
dead that they were wood roaches bc they cannot live indoors. Please help
me bc i am freaking out not nowing if the one with wings was a wood roach
or a american roach. My husband squashed it to bits or i could have a pic
for to send ya. Thanks!

The American and Wood roaches look very much alike. Rather than trying to
describe the difference, simply Google them and click on "Images" at the
top of the Google page. You'll see tons of photos from which you can tell
the differences. Same for roach nymphs (babies).

This is my question, I read some of what was written and so I'm guessing
what I been calling waterbugs are actually wood roaches? They look just
like german roaches but are HUGE...I rarely ever see them in the winter,
but once the weather starts getting hot/humid they are everywhere and I at
least see 1-2 in the house a day which is REALLY grossing me out to the
point that I lose sleep. Since I read that these kinds of roaches like hot
weather..would having a a/c on prevent them a bit? also majority of my
house is wooden floors, does that cause them to get into my house through
the floors or something? not sure what to do, do I need a exterminator?
Thanks in advance for any help.

First, getting an exact ID will eliminate the guessing as to whether your
roach is a wood, American or Oriental (waterbug). Each of these roaches
have unique habits.
If, in fact, your roach is a wood roach, you can treat the frames and
thresholds of windows and doors, turn off outside night lights and seal up
cracks around windows, doors and vents. I like the Xcluder product for
sealing up stuff and a product like D-Force HPX for the treatments around
doors and windows. You can find both products at
shop.asktheexterminator.com.

Hi there!
I've been checking this page to determine the kind of roach I have found. I
live in Nebraska and should tell you that my apartment is directly across
from a field that goes to a creek. I have seen a couple of these bugs at
the front entrance hanging around with the porch light on. I found one on
my counter (yuck!) by my sink with the light on. Today my cat must have
killed one overnight as it was dead by his food. I'm hoping it's a wood
roach but who knows! It looks like there is a creamy dot by it's head but
it doesn't look like a stripe but this roach is only about 3/4" long.

Hi,
Our home is 7 years old and the lot was all wooded. We are on an acre which
is cleared but beyond that it is all wooded. We have a crawl sapce and
attic.We are in Southeastern North Caroline near the coast. Summers er very
damp and hot. We never really had a roach problem at first, every once in
awhile I would see a wood roach or water but, but in the last 2 years we
have every bug known to man, and some not. Last summer the wood roaches
were coming in some how but not enough that it really bothered me that much
and the cats would get them for the most part, but this year it seems that
I have 2 species, and the american seems to be quite comfortable coming in.
I noticed that they were coming out of my vinyl siding on my front porch so
I walked around the house at night with just a flash light, and they have
made a home it seems in my siding above the brick and under the siding and
it goes all the way around. I also noticed the in my crawl space. I just
got what looked like an american cock roach climbing the wall upsatirs in
my hall only this one was rounder without the noticable wings and fatter
but still creepy. This creatures are huge and I mean huge. The wood roaches
are not as fast as the americans but both are just frweaking me out. I
cannot sleep at night, right noe it is 4 am .. I am an idiot when it comes
to cleanliness. Both neighbors on either side of me have monthly
exterminators, but my husband just went back to work after being laid off
and I cannot afford every month. Now if it is necessary I could get one
until the problem seems to go away, but I cannot keep paying for one. This
is scaring me. It is like a horror movie outside at night or like a big
party for them. The are also hanging out on my wood deck. I know they have
to vbe coming in through the arric and fire place since they are living in
the siding. Please any advise would help. I have no idea wha to do. I have
pets and do not want to harm the with pesticides..
Thank You
Sincerily

First, no matter what treatments I recommend, if you follow the label your
pets are safe unless you apply the pesticides directly on your pets.
I suggest applying a granular pesticide around the exterior perimeter of
your home. I like Talstar PL. I also suggest applying Tempo 1% dust into
the cracks of the siding where you see the roaches.
Both products are available by clicking "Pest Control Products" at the top
of this page.

I have a pool and a Palm tree in my back yard in Houston, Tx and one night
while in the back yard during a pool party we were rained down by a bunch
of water bugs or wood roaches from the Palm tree. Can please tell me how to

LOL Thanks so much.

10 Dec 2010, 13:28
Good luck! American roaches live under the bark of trees. They love the
tops of palm trees. The palms and the pool give these roaches all they need
to survive and thrive. Your situation calls for help from a tree company
with the equipment to spray the trees. The treatment will only reduce the
roach population, not eliminate it.

Hi. I live in a house down in Alabama. Now, when I lived out in Tennessee,
in the forest, I never had a problem with wood roaches. We see five or six
a day in my house and if you're quiet in my bathroom, you can hear them
scurrying inside the wall. I've checked all my windows and doors, we don't
use firewood, so I have no idea how they're getting in unless it's somehow
through the ventilation system. Any thoughts or ideas would be most
welcome. The information that I've read, along with what is on this page,
states that they do eat wood. Does this also mean they would eat the wood
studs inside the walls as termites are wont to do? Should we perhaps have
the house checked and treated for them along with having the wood studs
checked?
Thank you!
Ask the Exterminator
04 Apr 2011, 12:35
The article says they eat decaying organic matter. They are not wood
eaters, per se. They aren't like termites. House studs are not decaying
organic matter. And as for treatment, I need to ask if you read the
article?

Please Help! Flying roach looking bugs on my porch @ night. They fly to the
light like moths do. Light brown(gold) about 1 in long. What are they? I
live in MS near the flooded areas (not too close, a few miles away from any
standing water) Did the Flood bring these? I've lived in this area for over
25yrs and NEVER seen this. Also I have potted flowers (which probably
contain 'some' organic matter in the miracle grow) but a friend who has the
same bug problem does not have flowers near. What are these things and is
there anything we can do to deter them from our porches,decks,homes??
People in our community that have seen these bugs also say they bite;

Hi,
Your page is great! Best info I've found on wood roaches so far. Here's
my situation:
Part of my roof was recently repaired (new shingles, insulation, the works)
in my three-family home. The roof needed to be repaired due to the
inclement weather this past winter, causing ice dams and roof collapses
everywhere around here (I live in CT).
I found about 5-10 of these guys suddenly a week ago, approximately one
month after the roof installation. I understand that incubation is about
4-6 weeks, which is why I'm thinking my new guests have everything to do
with the roof being so moist and decaying from the inside out before it was
repaired.
I kept one specimen (who now lives in an empty water bottle on my kitchen
counter. His name is Charlie. :) to watch him grow - he shed his first (at
least I think 'first') exoskeleton the other day, and he is definitely a
wood roach. All of the behaviors line up - being attracted to light, easy
to catch and kill, and they're not so interested in my kitchen or
bathroom.
My question is, why have I seen so many if they do not breed indoors? I've
sealed every crack in my unit on the second floor, sprayed pesticides
specifically for roaches (ones that even kill Germans for 12 months), and
put out 24 baits, following all instructions to the letter. Still found a
live roach today about a week after my extermination efforts.
Interestingly, the 1st floor tenants have not found a single roach.
Additionally, I have found a LOT of these outside lately (both around my
house and as far as a couple of miles away on a hiking trail). All nymphs
about the same age, it seems.
So, long question short - is it possible an egg may have fallen into my
house through the roof? If so, I'm assuming I've got quite a few. Just
wondering if there is anything to worry about. From your article, it
sounds like I should be fine - just seems like I have a unique situation
with the roof, so I wanted to ask.
Thanks very much in advance for any advice!

Thank you! Now I know I don't need to be freaked out in the future! The
other day I was at a friends house sleeping in the basement (I stay over
frequently). At 3:30 I was awoken to a weird noise right behind my head. It
freaked me out enough I jumped up. When I did that something flew at my
head beating it's wings. When I opened the room door I saw what looked like
a plague come to life. Insects everywhere! The kids had left the outdoor
open. That morning when I ventured downstairs I found a very large but
skinnier than normal roach at the foot of the bed. Since they like lights,
fly often, and are nocturnal this roach makes perfect sense. My question is
why it would venture from the well lit playroom to the dark guest bedroom?
Hmmm...

I'm hoping what I've seen is the wood cockroach, but appears much lighter
in color than the pic, a light tan with maybe a slight reddish tint. I
haven't seen them fly, but have only seen them outside typically coming out
around dusk. They're not really skiddish like other roaches. I have seen
them in 2 different states in a variety of habitats: leaf piles, under
deck, in port-a-potty, in garden shed. I'm pretty sure no other markings,
like that of a German, but my natural reaction is to squash and run so I
cannot 100% guarantee my observations. Would it be safe to assume it is
the wood cockroach?

So lately i have been seeing at least 1-2 big roaches weekly right on

told it was a wood or palmetto roach . But today i saw a smaller version of
the same type of roach that have normally been in my home.And i didnt even
think to look at markings or anything like that..but i guess my question is
could this vermint have been a american roach or just a small palmetto? And
also are wood roaches typically attracted to water as well..i just put up a
8k gal pool.

Roaches go through gradual metamorphosis, which means they go through
several growth stages as they mature into adults. You may have seen one of
the immature stages of the roach. Most roaches are attracted to water
sources.

Hello! So i have a window unit air conditioner. I was wondering if
woodroaches, or any bugs for that matter can fly or crawl through the vents
to come inside? If so, can i spray the vents with the pesticide you
mentioned?
Ask the Exterminator

Usually, the internal filter of a window air conditioning unit will keep
insects out. If they are getting in, they most often come in around the
seals that hold the unit in the window. Do not use pesticides in the vents.

Before I get started I would like to say "I've read the article"...
I am in Alabama and have big black roaches crawling through the house.
It was built around 1900. So, when we purchased the house, and prior to
doing any renovations, the first thing we did was put up 8 small roach bomb
cans in the downstairs garage/basement.
After 5 days we came back and found at least 400-500 of the huge black
roaches dead on the floor and 50 or more dead in the house.
Since you say wood roaches only live in trees, what type of roach do you
suspect I have and how can I control them without using the roach bombs.
Ask the Exterminator
13 Jul 2011, 14:59
Sounds like Oriental roaches. These roaches thrive in moist, cool areas. If
water is collecting under the slab of your home I suggest attending to the
water problem first. Then and only then can you attempt to rid your home of
the roaches. Once the water issue is resolved you can use any number of
granular insecticides to kill off the roaches. Click on "Pest Control
Products" at the top of this page to find products for cockroach control.

It's not necessarily the product, but it's more about how you use it. You
have to understand the habits of the insect so you know where to place the
bait. You have to understand the chemistry of the product so you know how
to use it so it won't become contaminated with other chemicals.

I live in Maine. Ive never seen a cochroach before except 25 years ago
when i lived in the local city of Portland and the whole block of very old
connected brick buildings was infested, so i do know what they look and act
like (VERY fast-moving). Since then I have lived in many other places in
Maine and never seen one. Ive been in my current house for 10 years. Last
week, two days in a row, I saw what looked like, and moved crazy fast like,
a cochroach. It was about 1/2 inch long, more brown than black. However,
it flew. I went after it and killed it so it was non-recognizeable at that
point. My friend who owns an extermination business says it sounds like a
wood roach. However, I see a note here that they are easy to catch. This
was not in that it moved VERY fast like a regular roach. Based on these
details, could it also be a regular roach even though it flies, and ive
never seen a smaller one or others since? And can it be a wood roach even
though it moves fast? Which do you think it is? Thank you, Rosanne

terrible phobia of flying roaches so I actually evacuated my house! Before
I left, I saw the roach running towards the open window. Do these
creatures know how to escape back to outside? How can I know that it is
gone? If it didn't leave, what will it do during the daytime? Do
woodroaches go into cabinets and dark places like other roaches? I will
likely use a fogger tomorrow when I go back home because I can't live with
a roach...
Ask the Exterminator
08 Aug 2011, 09:17
Sometimes they are able to find their way back outside, but there is no
guarantee. They will go into hiding and will eventually die for lack of
food. The fogger may or may not work. The fog does not automatically find
its way into cracks and crevices. You have to move things and open spaces,
then direct the fogger into the openings in order to get the best results.

According to Professor Srini Kambhampati, Professor and Chair of the
Department of Biology at the University of Texas at Tyler, Texas, he has
not heard of common wood roaches making any sound (most cockroaches are
heavily dependent on pheromones for communication). The wood-feeding roach
(Cryptocercus) on the other hand, may produce some sound unintentionally
since they live inside galleries excavated in logs.

First rule of pest control is identification. If you don't know what you're
looking at you can't know how to treat it. Either collect an insect and get
it identified or call in the pros.
