Are Wood Roaches Dangerous?

As a rule, these creatures – roaches I mean, lead an active nightlife in human accommodation and get out of their shelter only when you are asleep. Encountering a roach during the day is quite a rare case, that’s why you are perplexed about their fearlessness when you see a leisurely crawling roach during the day.

In this article we will tell you what they are, why they are not afraid of you and how to get rid of such “tourists”.

What are the Wood Roaches? Some Helpful Facts

The brave wood roaches are the roaches of Parcoblatta genus of the Blattellidae family. It consists of 12 species of native North American wood cockroaches, including the Pennsylvania wood roach, Virginia wood cockroach, western wood cockroach etc. Don’t be misguided by the geographical names of the species: they are spread across the US  in a number of states. Various kinds of wood roaches differ according to their size, color and the states they inhabit. Pennsylvania wood roach (Parcoblatta pennsylvanica) is the largest as it can reach 1-1.3/4 inches in length. Other species are substantially smaller; they are 0.5-1 inch long. The males of any species fly rather fast (although, they can’t fly long distances) and females are completely deprived of this enjoyment.

Wood roaches aren’t household pests. They are outdoor-dwelling cockroaches: they infest rotten wood, and settle right under the bark and other moist places of the forest. If the conditions are favorable, they will never abandon their home forest, but in case of drought or lack of suitable food they set off in search of a better life in a house, located near the forest.

How Do Wood Roaches Enter the House?

Shelter search is a necessary measure for the wood roaches, and they will be grateful if you are the type of person that never turns off the light on the house porch. The males perceive a light bulb as a giant torch looming in the distance (the females usually stay back in the forest). Once they reach the porch, they fall and crawl inside under the door. Thats it, mission completed.

Good to Know! Those homeowners who have wood sidings, wooden shingle roof (it is cedar that is especially preferred by the wood roaches) and who live near the woods are especially at risk.

The alternative scenario goes as follows: you can bring them into your house with infected rotten logs found in the woods or stored in the backyard for a long time. The light and dark-brown brown wood roaches perfectly imitate the wood, and thus you might not even notice them. As a result, these aliens would travel all around your house and you might encounter them not only in the living areas, but also inside the garage or near the gutter.

The Differences between the Wood Roaches vs Cockroaches

Once inside, a wood roach behaves differently from a regular cockroach, such as an American or oriental cockroach. According to the Iowa State University of Science and Technology specialists, wood roaches are not secretive; they are active both during the day and at night and they are less likely to scamper out of sight when approached. Also, they will wander about the house without congregating in any particular location”. Furthermore, the entomologists calmly add that a wood roach infestation is temporary as unlike their pest cousins, they don’t breed indoors as only their type of their home moist woods environment is suitable for their breeding. Any wood cockroach that found itself indoors will make you nervous and will shuffle through the garbage or sink in search of something organic, but then it will inevitably die within a few days, as confirmed by the University of Arkansas Division of Agriculture entomologist Jeffrey K.

Wood roaches are temporary guest which would spoil neither the house nor the furniture and of course they wouldn’t think of biting anyone. Frankly speaking, this is a real relief. Still, the sight of these creatures isn’t inspiring, and it is necessary to get rid of them.

How to Get Rid Of Wood Roaches?

The good news is that the Institute of Agriculture and Natural Resources of University of Nebraska–Lincoln specialists have proven that since the wood roaches cannot breed indoors, there is no need in taking any special measures, like using artificial chemicals. Separate insects are easy to kill by simply stepping on them. However, if you don’t feel like getting your hands and feet dirty, all types of regular cockroach treatment (that can be found in our article How to kill roaches: 12 Best Traps, Poison Bait and Spray) will do.

  • Have a wide lawn which will become an excellent barrier against the wood roaches which they won’t be able to pass, even by air;
  • Keep the house (especially the kitchen and the bathroom) clean, take out the garbage more often;
  • Tidy up the backyard, remove the sources of stagnant water and get rid of rotten wood;
  • Seal all the cracks in the windows, walls and doors;
  • Turn off the porch lights at night and use the door kick plates.

They are not difficult to get rid of if you keep your house and backyard clean, which not true for the most common pest cockroaches, which will endlessly attempt to conquer your warm and cozy house.

  1. Yeah this article full of BS. Come tell that to my house is infested With wood roaches. Oh and by the way their breeding in my house thank you very much

    1. I also have a crazy amount of the Virginia wood roaches in my house. I feel they are infesting my house. I’ve found roughly 7-10; two alive before I called the pest control. I did have pest control spray and I’m using DE powder food grade. So frustrating. I can’t figure out why they keep coming into my house (ugh!). Definitely Virginia wood ones that’s been confirmed. I can’t figure why they have chosen my house.

  2. We just left our house for one week, because we were flying to rest, and on arrival we were already waiting for a surprise – wood roaches! They were everywhere! I’m already afraid of insects of different, and then there are the roaches, it’s just my phobia! But everything ended well, because my husband had long ago found a trap for cockroaches. For a couple of days we almost all caught. So do not despair if someone has a problem with these insects!

  3. “as they never hide at night and don’t fall on your face from the ceiling while you’re asleep” hell no I am on this site because one fell onto my phone as I was watching Youtube.

  4. I have wood roaches because of poor maintenance in the apartment i live at. Rather than the expensive replacement of the boards that are my patio they slapped a piece of OSB on top of it and covered it up. Needless to say the wood is now rotten and soaked through, i found their nest as there was 10-20 of them at a minimum. If they infest your house check for damp and wet spots that may be holding moisture that you are unaware of. I am a neat and tidy person and this situation pissed me off because i originally thought a neighbor was to blame for being a slob. Needless to say my lease will not be renewed come January.

  5. My CAR is infested. My assigned parking spot is surrounded by bushes, a tree, and ivy (it’s the first spot in the row) and my brand new 2020 car has at least 3-5 that I see whenever I get in the car. What can I do!?!? 😩😩

  6. i have a large deck. i have the boards replaced that rot but they stay wet undrneath deck. i have bought poison and sprayed under deck. replaced all mulch with rubber mulch. no rotten trees and i still see them in my house about 2 per week. am so upset have done everything i know. cannot keep them out of my house

  7. patricia a sutton

    all roaches are just nasty period. they crawl around and will crawl on you, yourself. SCARED TO EAT THEY MAY END UP IN YOUR PLATE.
