I met the Asian Roach!

Meeting the Asian Roach

The Asian Roach is a pest that is almost identical to the German Cockroach. Let me tell you how I was introduced to this pest! I was sitting in my shed one weekend enjoying a beer and the peace and quiet.

Then I noticed a roach fly in my shed while I was sitting there. I saw the pest fly several times and I thought to myself, a flying German Cockroach. I haven’t ever saw such activity like that from a German Cockroach before.

When I went back to work that Monday, I told the fellows at work what I had seen. They all knew I was sarcastic half the time and thought I was crazy.

A few months later we received information at our pest control office that we had a new pest moving into the area, that we was going to have to deal with. And what was that pest? It was the Asian Roach, the same one that was flying around in my shed.

Identifying the Asian Roach

When looking at the Asian Roach, they look identical to the German Cockroach. They are the same size at ½ an inch in length for starters. They are almost the same color, only slightly lighter in color and they have 2 light brown parallel strips behind the head to the abdomen.

It is hard to identify by color alone when there is nothing to compare to being both roaches are light in color to begin with. The color of the Asian Roach is also tan, only a little lighter.

So you can see how this characteristic would be hard to diagnose the pest. The Asian Roach has wings slightly longer than the German Cockroach and are strong flyers. This is the best identification you can use to distinguish the difference between these 2 roaches.

Another way to identify the Asian Roach from the German Cockroach is the female Asian Roach has wings that cover the egg capsule as the female German Cockroach only covers half of the egg capsule.

The males are very difficult to identify between the 2. They prefer to live outside other than inside a structure, but will come inside long as they can find a way inside.

They are also attracted to lights, such as porch lights and will make it into a home when the doors are opened as you come and go.

The Asian Roach living conditions would include; damp shady areas, mulch areas, moist composted areas such as piles of leaves, etc. They can be transported from place to place unknowingly in products such as mulch.

They first started in the southern states, and to this moment I have no idea how far north they have migrated.

They can appear in large numbers like any outside pest as they breed. The Asian Roach eating habits would include almost anything as they are omnivores.

Control of the Asian Roach

The “Asian Roach” prefers to live outside, so the first step would be to keep them outside. You should seal up any cracks or crevices in which they can enter the structure.

Examples would be gaps around pipes or water lines, torn door jamb seals, windows that need caulked, etc. Screens on open windows or screen doors where doors are left open will help keep the pest out of the structure also.

You can change your porch light bulbs to yellow ones to help not to attract the pest to your home with the possibility of them to access your home when you open the door.

The removal of any debris around the home will help in control of the Asian Roach as you will be removing their harborage areas. Mulch, pine bark chips, leaves piles; any of this is just a harborage area for all sorts of pests.

Although some people don’t care for the thought of removing landscape décor they are informed of the knowledge. Removing water sources near the structure such as dripping pipes or standing water will help with control of the Asian Roach.

Keep outside trash cans clean, away from the structure, and sealed will also help eliminate their food source or draw them away from the structure rather than to it. Sanitation plays a big part whether it is inside or outside.

Chemical control of the Asian Roach

For chemical control of the Asian Roach outside granular baits work very well. Remember they are strong flyers and can go long distances; therefore a large area may need treated to keep them out of the structure. A residual spray can be used for a perimeter application also if needed.

Microencapsulated or wettable powders would be a good choice for this application. Treating around windows, door frames, porch lights, etc are good areas to control the pest and help to keep them from entering the structure.

When treating areas such as mulch beds, note that the chemical may not reach the pest because of the thickness of the beds. Some of the targeted pests may crawl around the treated area passing it by or either fly over the chemical barrier.

There are several factors to know when controlling any type of pest. For control of the Asian Roach inside a structure you have multiple tools that can be applied if needed. But the whole idea is to control the pest before it enters the structure.

For inside control you have residual sprays, dusts, baits, aerosols for control in areas where they permit according to the labeling. When controlling the Asian Roach always follow the directions on the label and keep pets and children away from treated areas according to the labeling.
