Oregon has a Mediterranean climate with long, warm, humid summers and chilly, snowy winters.
These two ends of spectrums of quite different temperatures significantly impact cockroaches in Oregon.
Therefore, In summer, you will see many cockroaches while they hide away in the more profound and warmer parts of indoor spaces in winter.
Yes! There are a lot of cockroaches in Oregon, including the German cockroach, the most common cockroach that infests indoor spaces.
The American, Brown-Banded, and Oriental cockroaches are also common cockroaches in Oregon. However, these roaches less commonly infest indoor spaces.
Parcoblatta American, or the Western Wood Cockroach, is also native to Oregon and is found in forests, including Fremont National Forest and Umatilla National Forest. However, it prefers to live in the wild and is an accidental intruder.
Oregon is surrounded on one side by the warm pacific ocean and on the other side by chilly peaks, such as Mount Hood.
Therefore, cities such as Portland usually remain cold throughout the year and have the lowest rates of cockroach infestation.
Contrary to that, cities such as Dalles have warmer temperatures and help roaches flourish, breed, and infest throughout the year.

Cockroaches in Oregon are Common
There are at least 4500 species of cockroaches known to date. The US alone houses at least 85 species of cockroaches.
Although most roaches live in the wild and never infest homes, some of the tiny roaches species are the main culprits in an infestation.
The exact number of species in Oregon is unknown, but it’s confirmed that at least eight types of cockroaches live in Oregon state.
Long story short, cockroaches in Oregon are common; highrise buildings, apartments, restaurants, and cafes are the hotspot of roaches in Oregon.
In addition, millions of visitors visit Oregon state each year and might bring cockroaches along with them in their luggage or might take them.
Types of cockroaches in Oregon
Interestingly, the weather at one end of Oregon might differ from another. For example, you may be feeling extremely hot in Dalles while chilly in Oregon.
Similarly, the High land desert might be housing a different type of cockroach than the Fremont Forests of Oregon.
However, a few types of cockroaches in Oregon are common in almost every place.
1. German Cockroach
The German cockroach is the most common Oregon roach. It is tiny and is half an inch in size. It has dark stripes on the back of the head, which make it different from a Brown-Banded cockroach. German roaches have two sets of wings, but they can’t fly.
The German cockroach is the only one capable of living indoors in Oregon. It can’t survive in the wild. Therefore, it infests houses, highrise buildings, damp basements, and restaurants. Moreover, they also love to infest bedrooms and kitchens.
Hotels in Indiana are the hotspot for German roaches because many tourists visit them each year, bringing and taking German roaches, their babies, and eggs.
German cockroaches spread diseases like typhoid and paratyphoid fever, dysentery, and cholera because they visit sewers regularly.
They also trigger allergies and asthma episodes in atopic individuals. Moreover, German roaches reproduce very quickly and infest very heavily.
2. American Cockroach
This is the second most common cockroach in Oregon. However, it rarely infests indoor spaces.
American cockroaches are found mainly inside gutters, damp basements, under the rocks, and sheds. They infest indoor spaces in Indiana when the outside temperature increases above their threshold.
The American cockroach is one and a half to 2 inches with brown color with a flat body. It has flight-capable wings and reproduces quickly. The American cockroach has a life span of up to 2 years.
The American cockroach, or the flying cockroach of Oregon, is notorious for flying toward flashes of bright light or when feeling threatened.
3. Brown Banded Cockroach
Brown-banded cockroach is also among the most common cockroach found in Oregon. However, it is different from the German roach because it has two noticeable lighter stripes across its whole back hence named Brown Banded.
Brown Banded Cockroach measures about ½ inch long, and the male roach has wings covering the whole abdomen. However, the female Brown-Banded cockroaches have tiny wings with no ability to fly.
Brown Banded cockroaches are common in Oregon and more commonly infest homes, restaurants, and bars.
4. Oriental cockroach
Oriental cockroaches are found in small but noticeable numbers in Oregon.
The Oriental cockroach is 0.71–1.14 inches with a dark brown to the glossy black oval body. Interestingly, the female Oriental cockroaches resemble Florida Wood Cockroaches.
The male and female both have short wings, but none fly, excluding them from the group of flying roaches in Oregon.
Oriental Cockroaches live in dark and moist places near decaying organic matter, sewers, drains, damp basements, porches, and other damp locations.
Oriental cockroaches rarely infest indoor spaces in Indiana but sometimes are seen in damp basements in hot and humid cities like Dalles.
5. Wood Cockroach
Unlike other roaches, Wood roaches are native to Oregon. They live in forests in large numbers and are accidentally carried indoors with firewood.
Parcoblatta Americans species of wood cockroach infest Oregon. Florida Woods cockroaches are not found in Oregon.
Wood roaches infest huts and structures made of wood but are easy to exterminate because they are less shy than other roaches and roam freely.
Although all cities are infested with Wood roaches, Portland has the highest infestation rates with wood cockroaches.
Other Types of Cockroaches in Oregon
Smokey Brown, Asian, and Australian cockroaches are very rarely found in Oregon. They are carried mainly by tourists but often fail to establish their colony. Moreover, these roaches mostly love to live outdoors and rarely infest indoors.

How to Get Rid of Cockroaches In Oregon?
Before getting rid of roaches preventing them from infesting your living space is more important. Therefore, follow these guidelines to prevent roaches in Oregon from invading your space,
- Pick up clutter, spilled food, and garbage regularly.
- Adequately cover garbage bins and bathroom drains when not in use
- Use Natural Repellents to keep roaches away
- Keep mothballs inside your luggage when traveling to Oregon
- Cover crevices and gaps in doors and windows with masking tape
- Use window mesh screens to prevent Wood and American roaches from flying indoors
- Use IGR spray or device inside the house. It prevents roaches from maturing into adult bugs.
- Keep lights dim on the patio and backyard to prevent Wood roaches from entering your space.
Next, if you have an established infestation with Oregon roaches, follow these three simple steps to get rid of them efficiently and effectively,
Step 1: Using a bait
Using bait is an excellent method to get rid of cockroaches inside your bathroom, cupboards, kitchen cabinets, and basement, which are all the favorite spots of cockroaches.
Cockroach Baits are better than sprays as baits will kill the entire colony.
You can get your hand on many baits, but these are my favorite ones. Use each of them according to the instructions on the pack.
– Bengal Roach Killer is a dry spray bait, very easy to apply and use. (How to use guide)
– Advion Cockroach Gel Bait is the most effective gel you can buy.
– Hot Shot Liquid Cockroach Trapper and Killer is the best trap you can get for cockroaches.
– Combat Max 12 Month Roach Killing Bait is the best bait out on the market.
Step 2: Using an IGR
Using an IGR helps ensure the roach nymphs don’t grow into adults. Cockroaches are notoriously fast breeders among insects in Oregon. Using an IGR spray will keep it in check for you.
An IGR alters the internal hormones of roaches to molt. As a result, the roaches can not transform into adults and fail to reproduce.
Gentrol Growth Regulator (Amazon Link) is the only and the best IGR device for roaches. It’s easy to use. Just purge one of them and place it in a hidden place inside your bathroom.
Step 3: Insecticide Spray or Roach Bombs
Insecticide spray or roach bombs are quick solutions for eliminating cockroaches in Oregon. However, Insecticide spray kills roaches but does not destroy eggs; hence, we often start to see roaches again just after a few weeks.
To get rid of Oregon cockroaches, seal all doors and windows, turn off ventilators or air conditioning and spray around all the corners and cockroach hiding places. Then, wait for 30 minutes before you ventilate the room.
