how long do cockroaches live in a house
Cockroaches are one of the most successful, adaptable, and prolific pests. They are also one of the oldest. Fossil records indicate that cockroaches have existed for about 310 million years. There are over 3,000 different species of cockroach—and they all love to live in homes. Cockroaches can thrive almost anywhere humans do because their adaptive nature allows them to withstand nearly any conditions. They can live alone or in colonies, feed on trash or human bodies, hide in small cracks or crawl openly through the light of day — whatever the circumstance, cockroaches make the best of it and thrive. There are several species of cockroach commonly found in homes and buildings. Let’s take a look at these roach species and how you can get rid of them…
American Cockroach
The American cockroach is the biggest roach species. They are reddish-brown in color and can grow up to around two inches long. American roaches are often found in homes, especially in warm, humid places like kitchens and bathrooms. They are also common in sewers, drains, and other areas with high moisture. These roaches leave a pheromone scent that attracts other roaches, so an infestation can spread quickly. American roaches are nocturnal and usually spend their days hiding in cracks and crevices. They are omnivorous and feed on a wide range of things, including plants, food scraps, and books. An American cockroach can live for up to a year, mating only once during its short life. Once mated, the female carries her fertilized eggs for about six months, dropping them one by one as she grows ever larger. When the eggs finally hatch, the young roaches remain in the mother’s abdomen for another month, at which point they break out and go off on their own.
German Cockroach
The German cockroach is smaller than the American roach, growing to about one inch in length. These roaches are brown in color and prefer to live in warm areas with a lot of moisture, like bathrooms and kitchens. German roaches are nocturnal, but they tend to be more active at night than their American cousins. Like the American roach, the German variety is attracted to human food and can quickly infest homes through any food crumbs or spills. German roaches are also commonly found in restaurants and other public places where food is served. Like the American roach, the German roach leaves behind a scent that attracts other roaches, so it’s best to get rid of all of them at once. Plus, German roaches can secrete a substance that repels other roaches, making it difficult to get them all. A German cockroach can live up to two years, though most only live a few months. A female roach mates once and produces an average of 50 offspring during her life. The young roaches stay in the mother’s abdomen for six to eight weeks before emerging as fully grown roaches.
Brown-banded Roach
The brown-banded cockroach is smaller than the American and German roaches, growing to only about half an inch long. These roaches are dark brown in color and prefer warm conditions with high humidity, such as kitchens and bathrooms. Brown-banded roaches are nocturnal, but they tend to be more active during the day than other roaches. The brown-banded roach is less likely to leave the home than other species, however, so it’s not as likely to be found in other areas. Brown-banded roaches are attracted to human food, but they don’t spread as quickly or abundantly as the other roaches. A female brown-banded cockroach mates once and produces about 40 offspring. The mother roach carries her fertilized eggs for about six months before dropping her offspring one at a time as she grows larger. The young roaches stay in the mother’s abdomen for another month before emerging as mature roaches.
Oriental Cockroach
The oriental cockroach is similar to the American roach in size and color, but it’s not as abundant. These roaches can be found in the same places as American roaches, but they are much less common. Oriental roaches are nocturnal, as are most roaches, but they are not usually found outdoors. Rather, they prefer to live indoors in warm, humid, dark places, such as basements or the corners of large rooms. Like the other roaches, oriental roaches are attracted to human food. A female oriental roach mates once and produces about 40 offspring. She carries her fertilized eggs for about six months before dropping the young roaches one by one as she grows larger. The young roaches stay in their mother’s abdomen for another month before emerging as fully grown roaches.
Confused? How to Tell the Difference Between Different Roaches
One of the most confusing parts of fighting roaches is knowing exactly what species you’re dealing with. Even roaches themselves have a hard time telling one species from another; studies have found that roaches are unable to recognize members of their own species even when they are living in close proximity. In order to effectively combat roaches in your home, you need to know which species you’re facing. Fortunately, there are a few ways you can tell the difference between species of roaches. – Size: You can tell the difference between roaches based on size. The biggest roach species is the American roach, followed by the German roach, and then the oriental roach. The smallest species is the brown-banded roach. – Color: Roaches also vary in color. The American roach is reddish-brown, the German roach is brown, and the oriental roach is a darker reddish-brown. The brown-banded roach is a darker brown. – Location: Another good way to tell which species you’re dealing with is the location where the roaches are present. American roaches are more likely to be found in kitchens and bathrooms, whereas German and oriental roaches prefer to be in basements. The brown-banded roach is more likely to be found in kitchens and bathrooms than other roaches.
How to Get Rid of Cockroaches in Your Home
The best way to get rid of cockroaches in your home is to keep them from getting there in the first place. This may sound like an impossible task, but there are a few things you can do to keep roaches out of your home. – Seal Cracks: One of the best ways to keep roaches out of your home is to seal all cracks in your home’s exterior and interior walls. Of particular importance are utility and sewer pipes that may lead inside the walls. You should also seal any holes leading to the outside, such as those in the eaves of your roof or in the fascia boards. – Keep Food Out of Sight: Roaches are attracted to food, so it’s important to keep food out of sight and off the floor. Keep cabinets clean and store food in tightly sealed containers. Clean up any crumbs and spills as soon as they happen. – Keep Food Away from Water: Another way to prevent roaches is to keep food away from sources of water. This means keeping dishes clean, sinks dry, and pets out of the kitchen. – Seal Openings and Install Doors: Make sure all doors are firmly shut and have weather stripping or insulation in order to prevent roaches from entering your home.
