There are five species of cockroach in Michigan. Four of those species frequently infest Michigan homes and businesses. Despite their obvious similarities, there are distinct differences between each species of common Michigan roach. They look different, behave differently, and even eat different things. Most importantly, they come into your home in different ways.
Fighting roach infestations effectively means getting to know your enemy. Next time you have a roach problem, try to figure out which roach is troubling you, specifically. Once you know what youโre up against, youโll know what your next move should be. Here are the four roaches you may have to deal with in Michigan, and what to do about them.
German cockroaches
German cockroaches are the smallest, most common, and most important cockroaches in Michigan. They only measure around ยฝ an inch long, though long antennae may make them look larger. German cockroaches are tan or brown, except for two darker stripes running down their pronotal shields (backs). German roaches are considered the worst roach pest in Michigan for several reasons. Theyโre even more apt to attempting to get indoors than other roaches, and they also spread various diseases.
German cockroaches are common throughout Michigan, from Marquette to Detroit. Theyโre particularly common in urban and suburban areas, where they can access food easily. German roaches are particularly attracted to moist, warm environments. Like other roaches, German cockroaches are opportunistic foragers who feed on all kinds of detritus. Organizing and cleaning roach-vulnerable areas is the best way to keep German cockroaches away. Vacuum and clean your basement once a week, and make sure food doesnโt build up on eating surfaces.
American cockroaches
American cockroaches are the biggest cockroach found in Michigan. They measure around 1 ยฝ to 2 inches long, and they have slightly broader bodies than other roaches. Both male and female American roaches have prominent wings, but they donโt use them very often. Compared to German roaches, American roaches are more reddish-brown or than tan or dark and wider in shape. Like German roaches, American roaches may look larger than they are because of their long antennae.
American cockroaches are also frequently encountered throughout Michigan. Theyโre most common around food storage, making them a constant pest for restaurants, grocery stores, and other food-prepping businesses. American roaches often end up in homes after people inadvertently transport them inside on food boxes. Depriving these roaches of food sources is the best way to get them out of your home. Keep your pantry clean and crumb free, wipe up after meals, and keep food in airtight plastic containers.
Oriental cockroaches
Oriental cockroaches are often called โwater bugsโ because they love dark, damp, and cool areas near water sources. These roaches measure about an inch long, and look slightly rounder than American or German roaches. They may look somewhat โpill-shaped.โ Theyโre much darker than other common roaches, and appear very dark brown or nearly black. They may also look somewhat greasy or shiny. Both male and female Oriental roaches have wings, but they canโt use them.
Oriental cockroaches are a significant hygiene concern. They feed on all kinds of decaying organic matter, garbage, decomposing plant and animal matter, and waster. Their diets and affinity for humidity means they usually live in filthy areas. Theyโre frequently encountered in cesspits, sewers, trash dumps, or cisterns. Inside, they congregate toward humid areas such as basements and bathrooms, and they track their germs in with them. The best way to control for Oriental roaches is to control the humidity in your home carefully.
Brown-banded cockroaches
At ยฝ an inch long, Brown-banded cockroaches are nearly as small as German cockroaches, but they look quite different. Living up to their name, Brown-banded roaches have distinctive light brown bands across their backs. Theyโre also lighter brown or tan than the other roaches listed here, including the German roach. Brown-banded cockroaches have small, fully-functional wings and fly more frequently than most species. In addition to flying, these roaches are also generally more active than the others listed here.
Brown-banded cockroaches also differ from the other species listed here in their preferred habitat. Where most roaches prefer humid locations, brown-banded roaches want to stay dry. They tend to like living in cabinets, pantries, closets, and furniture where they can stay hidden, warm, and dry. Their ability to fly means you may find them higher up than most roaches. Controlling brown-banded roaches means keeping tight control over their food sources. Keep dry goods in airtight containers and clean regularly.
Each of these roaches are different, but theyโre all bad news. You donโt want any roach infestations in your home. By figuring out which roaches you have, you can take the right steps to drive them out for good.
