Even if humans disappear from this earth, then cockroaches will still be alive for a long time. However, this does not mean that they are allowed to crawl around in your house indefinitely. To deal with a cockroach infestation, you first need to know what cockroaches are living in your home. Many people don’t know that there are actually 4 types of cockroaches that live in the house that are classified as pests. The problem is much easier to deal with if you know what kind of cockroach you are dealing with.

Identification of brown striped cockroaches
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/c/c1/Identify-a-Cockroach-Step-1-Version-3.jpg/v4-728px-Identify-a-Cockroach- Step-1-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/c/c1/Identify-a-Cockroach-Step-1-Version-3.jpg/ v4-728px-Identify-a-Cockroach-Step-1-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Estimate the size of the cockroach. The brown striped cockroach is about 1cm long and is one of the smallest cockroach species. For comparison’s sake, imagine a brown-striped cockroach that’s slightly smaller than a 1 cent US coin (19 mm in diameter) (without counting the antennae, of course).
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/b/b6/Identify-a-Cockroach-Step-2-Version-3.jpg/v4-728px-Identify-a-Cockroach- Step-2-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/b/b6/Identify-a-Cockroach-Step-2-Version-3.jpg/ v4-728px-Identify-a-Cockroach-Step-2-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Observe the golden brown stripes. Contrary to what you may think, the name brown-striped cockroach is actually from the yellow stripes on this insect’s body. Look for 2 stripes – a very thick line at the bottom of your belly and a thinner line that runs across the center of your belly. [1] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/ff/Identify-a-Cockroach-Step-3-Version-2.jpg/v4-728px-Identify-a-Cockroach- Step-3-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/ff/Identify-a-Cockroach-Step-3-Version-2.jpg/ v4-728px-Identify-a-Cockroach-Step-3-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Consider the climate where you live. Brown-striped cockroaches usually live only in hot and dry climates. If you have cockroaches in your home but you live in a humid climate with low or moderate temperatures, it’s probably a different species of cockroach. [2] X Research Source
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/8b/Identify-a-Cockroach-Step-4-Version-2.jpg/v4-728px-Identify-a-Cockroach- Step-4-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/8b/Identify-a-Cockroach-Step-4-Version-2.jpg/ v4-728px-Identify-a-Cockroach-Step-4-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Check any nearby water sources. Brown-striped cockroaches don’t like water – so they don’t usually live near any water source. If you find a cockroach living near the sink or toilet, chances are it’s not a brown striped cockroach. [3] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f8/Identify-a-Cockroach-Step-5-Version-4.jpg/v4-728px-Identify-a-Cockroach- Step-5-Version-4.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f8/Identify-a-Cockroach-Step-5-Version-4.jpg/ v4-728px-Identify-a-Cockroach-Step-5-Version-4.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Notice if the cockroach can fly. Unlike German cockroaches, brown striped cockroaches will fly away when disturbed. If you see a small cockroach flying by, it is most likely a brown striped cockroach.
Identification of German cockroaches
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/a/a5/Identify-a-Cockroach-Step-6-Version-2.jpg/v4-728px-Identify-a-Cockroach- Step-6-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/a/a5/Identify-a-Cockroach-Step-6-Version-2.jpg/ v4-728px-Identify-a-Cockroach-Step-6-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Note the cockroach size. German cockroaches are slightly larger than brown striped cockroaches. They can reach a length of 1.3 cm, about the size of a US 1 cent coin (as above, you need to subtract the beard length).
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/39/Identify-a-Cockroach-Step-7-Version-3.jpg/v4-728px-Identify-a-Cockroach- Step-7-Version-3.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/39/Identify-a-Cockroach-Step-7-Version-3.jpg/ v4-728px-Identify-a-Cockroach-Step-7-Version-3.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Find two dark stripes. The most recognizable feature of German cockroaches is the two parallel stripes running from the back of the cockroach’s head to the cockroach’s wings. These stripes are dark brown and sometimes almost black. [4] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/d/d4/Identify-a-Cockroach-Step-8-Version-2.jpg/v4-728px-Identify-a-Cockroach- Step-8-Version-2.jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/d/d4/Identify-a-Cockroach-Step-8-Version-2.jpg/ v4-728px-Identify-a-Cockroach-Step-8-Version-2.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:” <div class=”mw-parser-output”></div>”}
Check to see if the cockroach is near a water source. German cockroaches like to live in warm and humid areas. You can often find them in the kitchen or bathroom, lurking next to the dishwasher or sink. German cockroaches are also notorious for appearing in trash cans, where they find most of their food.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0a/Identify-a-Cockroach-Step-9.jpg/v4-728px-Identify-a-Cockroach-Step-9. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0a/Identify-a-Cockroach-Step-9.jpg/v4-728px-Identify-a-Cockroach-Step- 9.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
In terms of the number of cockroaches. German cockroaches rank first among cockroaches living in the house in large numbers. If you think cockroaches are rampant in your home, chances are it’s German cockroaches.
Identification of American cockroaches
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/3/3c/Identify-a-Cockroach-Step-10.jpg/v4-728px-Identify-a-Cockroach-Step-10. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/3/3c/Identify-a-Cockroach-Step-10.jpg/v4-728px-Identify-a-Cockroach-Step- 10.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Observe the size of the cockroach. The American cockroach is considered the largest cockroach species with a length of up to 5 cm. If you place this cockroach next to a 25 US cent coin (about 2.4 cm in diameter), the coin will be only ¾ the size of the cockroach.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/1/1c/Identify-a-Cockroach-Step-11.jpg/v4-728px-Identify-a-Cockroach-Step-11. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/1/1c/Identify-a-Cockroach-Step-11.jpg/v4-728px-Identify-a-Cockroach-Step- 11.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Notice the color of the cockroach. American cockroaches have a special feature compared to other cockroach species in that they have a reddish brown color and amber sheen. Most other cockroaches are gray-brown in color. Check to see if the cockroach is glowing red. Also, you should look for two big, bold dots on the cockroach’s shoulders – that’s the only part of the insect that isn’t red.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/fd/Identify-a-Cockroach-Step-12.jpg/v4-728px-Identify-a-Cockroach-Step-12. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/fd/Identify-a-Cockroach-Step-12.jpg/v4-728px-Identify-a-Cockroach-Step- 12.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Observe the glossy outer shell of the cockroach. The American cockroach is also the most polished cockroach. Their outer shells, including their bodies and wings, could be called glossy, but not stunning. [5] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/f2/Identify-a-Cockroach-Step-13.jpg/v4-728px-Identify-a-Cockroach-Step-13. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/f2/Identify-a-Cockroach-Step-13.jpg/v4-728px-Identify-a-Cockroach-Step- 13.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Consider the food of this cockroach. American cockroaches have a reputation for only eating foods that are moist – like human and pet food – which makes them not only a personal problem but also a problem in the home. If you see a large cockroach eating your or your dog’s food, it’s most likely an American cockroach. [6] X Research Sources
Identification of Oriental cockroaches
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/07/Identify-a-Cockroach-Step-14.jpg/v4-728px-Identify-a-Cockroach-Step-14. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/07/Identify-a-Cockroach-Step-14.jpg/v4-728px-Identify-a-Cockroach-Step- 14.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Check the cockroach size. Oriental cockroaches are usually about 2.5 cm long, slightly larger than 1 US cent coin. Their body is tubular, meaning there is not much difference from head to toe. Female cockroaches are larger than male cockroaches. [7] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/f/fa/Identify-a-Cockroach-Step-15.jpg/v4-728px-Identify-a-Cockroach-Step-15. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/f/fa/Identify-a-Cockroach-Step-15.jpg/v4-728px-Identify-a-Cockroach-Step- 15.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Look at the color of the cockroach. Oriental cockroaches are dark brown in color. When under certain light, this cockroach can appear black. Apart from the distinctive color, the Oriental cockroach has no outstanding markings. [8] X Research Sources
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/8/83/Identify-a-Cockroach-Step-16.jpg/v4-728px-Identify-a-Cockroach-Step-16. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/8/83/Identify-a-Cockroach-Step-16.jpg/v4-728px-Identify-a-Cockroach-Step- 16.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Notice the wings of the Oriental cockroach. The female Oriental cockroach is actually wingless. Male cockroaches have short, fat wings that cover three-quarters of their body, but even if they have wings, they cannot fly.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/0/0f/Identify-a-Cockroach-Step-17.jpg/v4-728px-Identify-a-Cockroach-Step-17. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/0/0f/Identify-a-Cockroach-Step-17.jpg/v4-728px-Identify-a-Cockroach-Step- 17.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Observe the area where you see the gecko. Oriental cockroaches can survive long winters in the cold outdoors by burrowing under moss or other mulch. When indoors, they will live in dark and damp places. In particular, this species of cockroach often lives in dark and cool water pipes and basements.
{“smallUrl”:”https://www.wikihow.com/images_en/thumb/e/e6/Identify-a-Cockroach-Step-18.jpg/v4-728px-Identify-a-Cockroach-Step-18. jpg”,”bigUrl”:”https://www.wikihow.com/images/thumb/e/e6/Identify-a-Cockroach-Step-18.jpg/v4-728px-Identify-a-Cockroach-Step- 18.jpg”,”smallWidth”:460,”smallHeight”:345,”bigWidth”:728,”bigHeight”:546,”licensing”:”<div class=”mw-parser-output”></div> “}
Areas infested by Oriental cockroaches often have an unpleasant musty smell due to the chemicals they secrete to communicate with each other.
Advice
- Brown-striped cockroaches often hide in warm, untouched areas, such as in the overhead compartments of shelves or wall cabinets.
- German cockroaches usually live in places where food is available, such as kitchens.
- If your home is infested with cockroaches, you must be very careful in handling them. If you miss even one area, the cockroaches will breed again and your home will be invaded by cockroaches again.
- If you have trouble with cockroaches, store your food in an airtight container to prevent infection. You should also put your trash in an airtight container.
- Oriental cockroaches often enter homes through drains and water pipes, inhabiting dark and cool areas, such as basements.
