Types Of Cockroaches: Identifying Common Species

There are quite a few different species of cockroaches in the world. Different regions deal with different species, so knowing which ones to look out for when you’re in Oahu can help you more quickly and accurately identify a cockroach problem in your house.

Two different types of cockroaches are active in Oahu, and both can be a major problem for homeowners. Those two cockroach species are German cockroaches and American cockroaches. These roaches share some similarities, but they are also quite different from each other. Knowing how to identify both of them starts by knowing what they look like.

German cockroaches are the most common type of cockroach in the United States. These pests are small, only growing to about half an inch in length. They have oval-shaped bodies that are light brown or tan in color. On their backs, just behind their heads, they have two darker brown stripes. German cockroaches have six legs, with each pair getting slightly larger as you move from front to back. They have two long, thin antennae. German cockroaches also have wings, but they don’t typically use them for flight, preferring to run from place to place instead.

American cockroaches are much bigger than German cockroaches. The smallest adults measure in at over an inch, and they can grow to over two inches in length. Reddish-brown in color, American cockroaches have a yellowish figure-eight pattern on their heads. Like German cockroaches, American cockroaches have six legs that get progressively larger from front to back and a pair of long, thin antennae. They also have wings, but unlike German cockroaches, they do use them to fly short distances. American cockroaches are also called palmetto bugs, Bombay canaries, and water bugs.

Both German cockroaches and American cockroaches prefer to spend their time in warm, dark, humid areas. When they get into your home, they are most likely to be found in the kitchen, bathroom, laundry room, or basement. While American cockroaches tend to move indoors when they can’t find food outside or when there is a big change in the weather, German cockroaches prefer to live in indoor locations and aren’t often found living outdoors.

Health Risks And Property Damage: The Hazards Of Cockroaches

Cockroaches have gotten a bad reputation over the years, and they have earned it. These bugs aren’t like many other nuisance pests that get into homes and are nothing but an annoyance. In fact, cockroaches are one of the most dangerous pests to end up with in your Oahu home, mainly because of the health risks they introduce.

What diseases do cockroaches carry? There are dozens of them. Studies have shown that cockroaches have been found to carry over 30 different types of bacteria on their bodies. That doesn’t include other types of pathogens or parasites. Some of the diseases cockroaches spread are likely familiar to you, while there are others that you may not have heard of. Gastroenteritis, salmonellosis, E. coli infection, typhoid fever, and cholera are all diseases that you have probably heard of that are spread by cockroaches.

How do cockroaches spread all of these dangerous illnesses? It has to do with their habits and behaviors. Cockroaches like to spend their time in dark, secluded areas with high humidity. When outdoors, you may find them in garbage bins, dumpsters, or sewers. When inside, they often take up residence in sink drains or under sinks in kitchens and bathrooms. 

While in these unsanitary places, it’s easy for cockroaches to pick up pathogens on their bodies. Once they start moving around, these pathogens will end up on the surfaces they touch as they move. If cockroaches are in your house, it’s only a matter of time before they contaminate your kitchen counters and cupboards or your bathroom sink or counter. The next time you prepare a meal on your countertop or set your toothbrush down beside your sink, you put yourself and your family at risk of coming into contact with those pathogens.

Cockroaches are also a threat to your respiratory health. The shed skins, saliva, and waste products of cockroaches trigger allergy and asthma symptoms in many people. If cockroaches are in your house, you may end up dealing with those health issues as well.

Eradicate A Cockroach Problem In Your Home: Call In The Experts!

Cockroaches are nocturnal pests, so if they get into your house, you might not realize it right away. They prefer to hide during the day and will come out at night to feed. Identifying a cockroach infestation in its early stages requires you to be looking for it. Check in out-of-the-way areas to look for roaches or their droppings. Check areas at night to see if you can spot any activity. 

With a more well-established infestation, it will become much more obvious that cockroaches are present. Cockroaches breed fairly quickly, so once a large population is in your house, their hiding spots become overcrowded, and cockroaches will be more likely to be active during the day, making them easier to spot.

Whether your infestation is big or small, you don’t want to wait an extra moment to start working to eradicate the issue. Cockroach pest control in Oahu should always be tackled by experts. Cockroaches are not easy pests to get rid of, which makes do-it-yourself cockroach control methods only mildly effective. Furthermore, getting at the root of a cockroach problem is often difficult for homeowners because cockroaches are good at hiding in areas that are difficult to access.

With PTH, you can be certain that your cockroach problem will be handled with care to ensure its full eradication. We tailor our services to your home’s particular needs so that you get the specific cockroach control methods necessary to eliminate every last cockroach in your Oahu home.
