Cockroach, Wood Roach

Common Name: Cockroach, Woods roach
Latin Name: Eurycotis floridana (Walker)
Common Family Name: Blattid cockroaches
Latin Family Name: Blattidae
Other Names: Florida woods cockroach, stinking cockroach
Origin: Native to southern Florida and the West Indies.

Biology

This outdoor cockroach is found under debris and vegetation piles around structures. Suitable harborage sites would be lumber or firewood piles, leaf litter, thick mulch, or within tree holes. It is able to reproduce parthenogenetically, meaning without males in the population. When disturbed the roach will exude a foul-smelling, oily liquid.

Identification: Adults are very large, reaching almost 2 inches in length. The color is dark brown to black, and the wings are reduced to short stubs at the front of the abdomen.

Characteristics Important in Control: Removal of potential harborage sites around structures by cleaning up debris will reduce populations. Exterior applications of a residual insecticide can prevent entry to structures, along with applications of granular bait insecticides.

Why the Wood Roaches??

Question:

I have been servicing this home for about 4 years for general pest control and never had a wood roach problem. all of a sudden the customer sees one here and one there. I have used Cy-Kick Cs with very little results and cannot find where the source is.

Answer:

Several kinds of roaches in the genus Parcoblatta are called Woods Roaches, including the Pennsylvania Woods Roach that is found throughout the eastern half of the U.S. The western states also get occasional invasions, albeit pretty minor, by species in the Parcoblatta, but they are usually just the occasional, single roach that mistakenly entered a structure. These roaches are capable of flight, and in winter may choose structures as their over-wintering site, entering through roofing, attic vents, under siding, or other openings leading to protective voids in the structure. By staying a little warmer within the home they then may be active in the cold weather, and be observed by the customers as they wander about.

These really are outdoor insects, and should be treated as the Occasional or Perimeter Invaders they are, much as you might treat for crickets, pillbugs, boxelder bugs, or any other insect that lives in natural, wooded or grassy habitats, but survives the winter by seeking the protection of structures. They do not become structural pests in the sense that our other pest roaches do, like German or American roaches that infest kitchens and eat our foods. Those few that I myself have found in my California home were dead when I found them, for my garage really is not a conducive habitat for the roaches. They would prefer the comfort of the dampness under a log or rock, but with nasty weather will move to more protected locations.

Depending on your weather to this point the source in this case could still be from the outside, so any habitat modifications you can recommend to this customer in the way of cleanup of debris and hiding places close to the structure will really help. Populations of most kinds of insects go through increases and decreases on a regular basis, so this just could have been an up-year in your area for these guys, for what reason only they know, leading to the greater sightings of them in accounts. I don’t have any experience with baiting for Parcoblatta, but pyrethroids used as “a barrier” treatments should do an excellent job in eliminating them as they wander.

    how do you combate carpenter ants if you can t see or find where there coming in from

  2. 2

    Carpenter Ants travel as far as 100 ft from their colony,
    so although you may have difficulties locating their colony,
    they are in fact coming in from the outside(that is, if you DO have carpenter ant problem).

    It’s a bit difficult to answer your question because of its brevity,
    but it seems that you do not know the entry point nor trail,
    but have seen the carpenter ants around your home.

    I will say that the best possible option right now be baiting.
    We have Maxforce Carpenter Ant Bait Kit that we sell at $39.50. It’s cheap, but very effective way of controlling carpenter ants when you do not know the entry point.

    However, in order to treat your problems better, you might want to do some inspection first.
    You can check on How to Get Rid of Carpenter Ants article for more information.

    Hi. Within the last year we moved into a new home. Long story short during the spring/summer months there is usually 1 to 2 woods roaches in the top crevices of our front door. I at first knew what they were and would gently transplant them to the neighboring vacant lot. They smell if you get to aggressive with them. But I am now after a year of living hear sick of them crawling in from the door jamb when we open the door every morning to get our daughter onto the bus. This is the ONLY place that I see them… Do you have any permanent recommendations to make our door a non suitable habitat for them??? Next I will be reading about silverfish… Thanks for your time.

    Sorry to hear of your situation. It must really be annoying seeing them every morning trying to forage indoors. The best product that I can recommend would be for you to use any long residual insecticide. Generally most of the concentrated insecticides will last you a good 2-3 months. So what you would need to do is do a thorough perimeter treatment with the insecticide around you home to create a sort of barrier around your house to prevent them from continuing to forage indoors. Good luck!

    Quick question

    Just moved into this house first summer for us is almost june now and starting to see frequent visits of wandersing roaches an walls they also fly long wings and are about an inch long. was wondering what kind they are and if they bite. Recently read an article of infants dying from roach bites.Thank you for your time.

    Hello Trent. Depending on the color or where you are located, the species might change. Not many roach species are good fliers, amongst all the species that commonly invade homes, the Smoky Brown Cockroach are good fliers. I’m pretty sure that roaches do not bite, however, I’m not 100% sure so please do not take my word for it. However, the most likely situation that may have occurred from infants dying may not have been bites but contaminated food. Roaches can contaminate food and they are known vectors of diseases and so really, the infant could may not have had an immune system that was developed enough to fight various disease pathogens from the roach. I hope that helps you! Please, if you have any other questions, just let us know!

    Hi I live in Louisiana and I have been in my house for six years never had a roach problem until a year ago they are in the cabinets we have cherry wood cabinets and they come out in July and go away in October I know they are wood roaches. I have taken everything out of the cabinets and try to wait to spray but they hide in the cabinets they leave droppings like rats but their roaches. Please help me I have small kids and I’m very concern

    Hi Monica,
    For roaches like that, especially in a secluded area like that, I recommend bait gel. You will place 3-5 pea-sized amounts 10 linear feet apart. The bait gels are harmless as long as your children don’t try to eat them. Bait gels have a delay kill effect. In the case of roaches, one roach will ingest the poison bait and live long enough to get back to its colony. Once it goes back, it will die and other roaches will eat its carcass. These roaches will therefore also ingest the poison and repeat the process all over again, leading to a domino killing effect. Bait gels take a bit longer to work than regular pesticides and they also require that you be meticulous and clean up any other food sources, but we find that they do the best and most thorough job.

    Hi! I live in Washington state and up to now did not think we even had roaches in our area. Last night I found a huge roach walking up the wall near some small windows. It was as big as my thumb so you can imagine my reaction to seeing it! My son and daughter helped me to get the vacuum and suck it up, then we took the bag up to the dumpster. I researched this and believe it to be a Western Wood Roach. We live in a wooded area with National Forest land bordering our complex and Forest service roads along one side. Why was this guy inside? We just went through extensive pest spraying for earwigs (inside and out) and I do not want to trade one pest for another. Was this just a fluke or should I be concerned? Thank you for any advise you can offer. We are all a bit creeped out about this now!

    Hello Michelle,
    Fortunately for you, wood roaches are unable to survive indoors. The one that you found could have just wandered inside through a door that was left open or a crack in the window or other cracks and crevices. This does however mean that you may have more outside. I don’t want to freak you out though because wood roaches are considered occasional invaders. If you really want to get rid of them though, you will have to do outdoor treatment with a bait. But no worries, the wood roach was probably a fluke :)

    Hi there,
    Tonight I discovered a roach nymph in my California house and of course I got freaked out. I immediately took to the internet to see if I could determine what variety I was dealing with. I was relieved to see that images of the Wood Roach nymph seem to match the critter I found 100%. Since I live in California, I am wondering how common Wood Roaches are in my state. I have never had roaches before in my house, but I did recently clear a bunch of rotting wood debris from my backyard and want to know how common is the Wood Roach in rural Southern California?

  12. 12

    Wood roaches can be found all throughout the United States, especially under wood debris or under materials that have begun to decompose. Fortunately, they are occasional invaders. Thorough outdoor treatment with a liquid spray will help to keep them out. Target all points of entry like any cracks or crevices in the structure, window frames, door frames, and any utility pipes that enter the building.

    Hey,

    I lives in louisiana and i just move in my house a year ago… And now i have dis roaches i c like everyday. I have done everything spray, bomb, i even clean everything out wipe it all down. The spray for roaches. But they never goes away they have babies also… I really think they came when my neighbors move in cause i didnt have them at first… What can i use. And where can i buy it from to get reid of those nasty things.

    Hi Dana,
    There are a few things that concern me. Before I address those things though, it is good that you are wiping everything down and keeping everything clean. This will eliminate the main food source for the roaches. There’s a couple of things though. When you say “spray”, I’m not sure if you are speaking in regards to aerosol sprays or the commercial grade residual concentrate sprays. You did mention bombing and if you are using the aerosol spray (like Raid), although it will kill them on contact, those ready to use type of sprays are really used for a clean out or an initial treatment, but you will not see lasting results. Also, I wonder if you live in an apartment or if it is a townhome where your neighbors’ units are attached to your own home. If this is the case, treatment for pests can be difficult because the pests are able to travel from home to home through the wall voids and piping. If it is a house that is separated from your neighbors’ homes, you can treat the outside with a residual concentrate spray to create a barrier with a product like Suspend SC or Cy-Kick CS and use baits like Dupont Advion Roach Bait Gel or Maxforce Magnum Roach Gel Bait.

    Hi, I have these huge black bugs in my house once a day I am finding them. It looks like a big black cockroach. Not the little brown ones that scurry from the light. They are big, black, winged(I think) and fast. I even found one in MY BED!!!!What are they? How do I get rid of them. I never had them before, have lived here almost 12 years!!!!!

    Hi Leslie,
    I wonder if you’re talking about Oriental Cockroaches (you should look it up and let me know if that is it). If it is, then they are occasional invaders. Right now, the seasons are changing and the temperatures are dropping at night and so it’s natural for bugs to look for a warm place to stay! They will try and come inside and unfortunately, most will succeed. You want to try and do a thorough outdoor treatment so that you can keep them out. Suspend SC is a great product to use on the outside perimeter of the structure. You want to create a barrier with the insecticide. Spray the entire perimeter of the structure by spraying a few feet up from the base of the structure and a feet out from the base of the structure. You also should pay close attention to treating window frames and door frames. Always read the product label before apply the product for complete dilution rates and application instructions. If you have any further questions or comments, please feel free to contact us again.
