The Types of Cockroaches That Often Appear In Homes

Several cockroach species have been documented in Louisiana, a minority of which are pests. The most common cockroach pests in Louisiana include German, American, Oriental, brown-banded and smoky-brown cockroaches. These cockroaches are more than just a nuisance within a home, as they spread allergens and disease-causing organisms. Two species, the German and brown-banded cockroaches, dwell primarily indoors, making them particularly difficult to control. All other pest species invade homes occasionally where they often maintain a long-lasting presence. However, in a wet and humid state like Louisiana, not every cockroach/es a person sees indoors is categorized as a pest. This may come as a surprise to some people, as spotting even one roach indoors is often reason enough to assume that an infestation has occurred, and identifying the species of cockroach found indoors is not always considered necessary. That being said, there are four roach species often found in Louisiana homes that pose no health threat to humans, and are not looking to set up camp indoors. These four species are not pests, but a few of them are commonly mistaken for pest species, which may prompt unnecessary calls to pest control professionals.

According to the LSU Ag Center, the Cuban cockroach, the red-legged cockroach, the September cockroach, and multiple species of woods cockroaches are not pests despite being found indoors occasionally. Woods cockroaches can be found on trees during the nighttime hours, and they are often mistaken for German cockroaches when they appear in homes due to their dark exterior and .5 to 1 inch body length. The September cockroach is also similar in appearance to a few cockroach pest species, only the September cockroach is particularly well suited for flying and a red-colored patch can be found behind their heads. This species is abundant on lawns and leaf-litter, and they are highly mobile during the day and evening hours during the summer, sometimes bringing them into homes. The red-legged cockroach is one of the most common roach species in Louisiana, and they can be identified by their conspicuous red legs for which the species is named. The Cuban cockroach is not easily confused with roach pest species on account of its lime green exterior, but they may become a nuisance during the spring and early summer when they take flight toward porch lights.

Is it normal for you to notice multiple roach species in your home during the summer months?

How Louisiana’s Common Cockroach Species Differ In Terms Of Pest Behavior And Infestation Tactics

Louisiana is home to many cockroach pest species, nearly all of which were introduced into the state from other countries. The most common cockroach pest species that can be found in Louisiana include German, American, Brown-banded, smokybrown, Asian, Surinam and Oriental cockroaches. The state is also home to recently introduced species, including Cuban, large brown, Australian and Florida woods cockroaches. The Pennsylvania woods cockroach has been found in Louisiana numerous times, but they are not as common as the above named species. The state is also home to several rural cockroach species that can become problematic in country homes on rare occasions.

Cockroaches are considered by some experts to be the most commonly reviled and problematic indoor insect pests, as roaches spread numerous disease-causing microorganisms on human food sources and indoor surfaces. Roaches also play a significant role in the development of allergic conditions, and they can exacerbate existing allergy symptoms, especially asthma. Unfortunately, cockroaches are also one of the most difficult types of insect pests control, and control methods differ tremendously depending on the species.

American cockroaches are said to be the largest roach pests in the US, as both males and females of this species grow to be around 2 inches in length. These roaches congregate in sewers, and they tend to infest the ground and below-ground levels of homes and buildings, particularly damp and musty basements. Pest control professionals usually resort to gel or granular baits to eliminate American cockroach infestations, but unfortunately, fully grown adult cockroaches cannot always fit into bait station entrances due to their large body size.

Unlike American and Oriential roaches, smokybrown cockroaches are rarely found in sewers, and their need for high-humidity conditions limits their habitat to the southern states. Despite their need for humidity, these roaches can be found anywhere in a house, including basements, crawlspaces and even attics. Smokybrown cockroaches are also large-bodied at around an inch and a half in length, and they are usually controlled with gel or granular baits.

German cockroaches are the most common cockroach pests, and just like the brown-banded species, German roaches dwell primarily indoors. Eliminating German cockroach pests from infested homes is difficult and requires a combination of methods. For example, sticky traps must be strategically placed around a home so that pest control professionals can determine the location of their harborages. These insect pests are only attracted to pheromone-based sticky traps, and many bait stations must be strategically placed throughout a household in order to successfully eliminate infestations. Professionals also spray minimal amounts of insecticide into small cracks and crevices where the roaches are known to hide.

Have you ever attempted to eliminate a cockroach infestation on your own and without professional assistance?

Rainstorms And Floods Prompt Smokey Brown Cockroaches To Invade Louisiana Homes In Massive Numbers

The German cockroach is the most widely distributed and the most common indoor roach pest species within the United States, and the entire world, for that matter. The German cockroach is one of only two roach pest species in the US that dwell solely indoors, the other species being the brownbanded cockroach. The American cockroach is the second most commonly encountered roach pest species within homes and buildings in the US. This species is notable for being particularly filthy, as they are well known for dwelling within sewers where they sometimes traverse through plumbing only to emerge from drains within people’s homes. The Oriental cockroach is another common indoor pest species in the US, but they are not as widespread as the German and American species. The smoky brown cockroach species is closely related to the American cockroach, but they cannot match the American species in terms of body size, as smoky browns grow to be slightly larger than 1 inch in body length, whereas the American roach can grow to 2 inches in body length. The smoky brown species’ habitat is largely limited to the southeast US, but they can also be found in southern California and parts of the midwest. The smoky brown’s dependency on high-moisture environments make them particularly abundant in Louisiana.

The tropical storm Barry, which is currently causing flood conditions along the Gulf Coast, is causing smoky brown cockroaches to invade homes in massive numbers in the region. Unfortunately, this behavior is typical of smoky browns during heavy rainstorms. According to entomologists with Louisiana State University, the roaches develop a sudden preference for indoor conditions during rainstorms and especially during floods. An example of this phenomenon is well documented in footage posted to Facebook, which shows an uncomfortably large amount of smoky browns emerging from an overflowing storm drain in Louisiana. This footage has gone viral, and has been featured in the media, capturing the fascination and disgust of people all over the world. Smoky brown cockroaches prefer to live outdoors, but they are in the habit of entering homes in order to feed. However, rainstorms and floods make the smoky brown’s typical habitat a bit too wet for the insect’s taste, causing them to invade homes in large numbers to avoid succumbing to rising water levels.

Why Is An Invasive Cockroach Species In The US Displacing Native Cockroach Species At An Unusually Rapid Rate?

Back in 1978, an invasive cockroach species was discovered at the Sharpe army depot in California. This species is known as the Turkestan cockroach, and since its discovery in the US in 1978, these cockroaches have been slowly displacing oriental cockroach populations in the southwest. Lately, Turkestan cockroach populations have been growing at an unprecedented rate within the southwest US, and many people are blaming the internet.

The Turkestan cockroach is often purchased online by people who keep a pet snake, as this cockroach species has become popular as a go-to form of food for pet snakes. The rapid spread of the Turkestan cockroach has been blamed on people who buy the insects online, as it is widely believed that the high Turkestan roach population in the southwest is due to specimens being sent to the region through the mail by snake food vendors. However, this is not the reason for the cockroaches’ spread across the southwest; instead, researchers with the University of California in Riverside believe that frequent military campaigns in the middle east and Asia have brought this cockroach species to the United States. This scenario seems likely considering that the first specimen found in the US was taken from a military base. After this initial discovery, more Turkestan roaches were discovered at other military bases, such as Ft. Bliss in El Paso. Since then, this cockroach has spread rapidly, displacing established populations of oriental cockroaches. Entomologist Michael K. Rust claims that the Turkestan cockroach is outcompeting oriental cockroaches within their own habitat. But the primary factor behind this cockroaches’ spread is its ability to reproduce at rapid rates. However, Rust claimed to be surprised upon finding that Turkestan roaches are widely available for purchase online, and he believes that the sale of these cockroaches could accelerate their spread if the specimens are not handled correctly. These cockroaches are common pests in homes and buildings in the southwest US.

A Popular Brand Of Carbonated Water Is Being Sued For Containing Chemicals That Are Used For Killing Cockroaches

It is always a bummer to learn that your favorite food or beverage product contains dangerous chemicals. Of course, given the remarkable advances that have been made in food preservation methods, we cannot always be sure what exactly is contained within processed drinks and food products. Since very few people in developed parts of the world are starving, some consider unpleasant or even harmful chemicals that find their way into our foods as a price we pay for the benefit of food abundance. However, this is a minority opinion, and the public reaction to ingredients that are not listed on product labels is always a negative one, especially when the unlisted ingredient turns out to be a legitimately harmful substance. If you are a lover of carbonated water, then there is a good chance that you have consumed the popular La Croix brand at some point in your past. Hopefully, you do not drink La Croix regularly, as the company that produces the popular carbonated water beverage is being faced with a lawsuit over the cockroach killing chemical that was allegedly found in the carbonated water during testing.

La Croix proudly advertises their “all natural” ingredients with the hope that consumers will regard their products as being more healthy than competing products. Despite this claim, one woman, Lenora Rice, had the La Croix brand carbonated water tested and it turned out that it contained a chemical known as “linalool propionate.” Linalool propionate is a chemical that is commonly used to kill cockroaches. In addition to finding this roach-killing chemical, Rice found that the drink contained a number of other synthetic chemicals. A CBS news team in Philadelphia recently broke this unfortunate news, which has since gone international. In response to the allegations, officials with La Croix have adamantly denied that linalool propionate or any other synthetic substance is contained within their beverage. Although further testing is needed in order to confirm Rice’s findings, consumers may want to wait before buying another pack of La Croix, unless you plan on using it to kill cockroaches, that is.

Do you believe that La Croix carbonated water contains a popular roach-killing chemical in all of their cans?
