Why Brown-Banded Cockroaches Can Be Difficult To Detect Within Infested Homes, And How Are These Roach Pests Best Controlled?

While German cockroaches are known to be the most common of indoor cockroach pests, one the more difficult cockroach pests to detect and control is the brown-banded cockroach. While most cockroaches seek out moisture when looking for indoor harborages, such as German cockroaches, brown-banded cockroaches are one of the few species that can not only tolerate, but prefer warm, high, dry areas. This makes locating and controlling their infestations much more challenging.

Brown-banded cockroaches are dark brown in color, with two light colored horizontal bands stretching across its wings and abdomen, and around ½ inch in length. Their preference for dry areas greatly increases the number of possible hiding spots throughout the house. Other indoor cockroach pests such as German and American cockroaches need more moisture heavy environments, and are most often located by a moisture source such as the kitchen sink. Brown-banded cockroaches, on the other hand, can be found in any part of any room in a home, including on the wall behind pictures, inside closets, behind dressers, near tables and chairs, as well as typical locations like inside the pantry or the bathroom. The brown-banded cockroach is sometimes referred to as the “furniture cockroach” because they can be easily introduced to a home through transported furniture and other items newly brought into a home from some other location.

Like all other cockroaches, brown-banded cockroaches are attracted to check out an area that has food they can consume. While brown-banded cockroaches can eat pretty much anything they can find, what makes them unique is their preference for starchy items, including in particular glue used to bind books, wallpaper, and furniture. This broad diet and decrease in environmental restrictions makes this cockroach pest difficult to just to locate let alone eradicate.

Using baiting systems to control brown-banded cockroaches seems to work better and have a number of advantages over other methods. The best way to go about this is by using glue traps first to assess the number of cockroaches present in different areas of the house, helping you locate the best areas to place the bait traps and how much bait you will need to use. A small amount of bait can actually have a significant impact on a cockroach infestation because of a phenomenon known as horizontal transfer. Even after one cockroach consumes the bait, many more cockroaches can be poisoned when another cockroach consumes that first cockroach’s feces, exchanges oral secretions, or the dead carcass of the poisoned cockroach is eaten by other cockroaches. Baits can still take time to work, though, and seeing a significant drop in numbers does not happen instantly.

Which Non-Chemical Cockroach Control Methods Are Known To Be Effective?

Cockroaches are a problem that everyone has to deal with. We’ve all come across cockroaches running across the kitchen floor in the middle of the night or racing out from a hiding spot in the basement or attic that has been revealed after someone moves a box or some other stored item. There seems to be no escaping these horrid pests.

The first thing that generally comes to mind when it comes to controlling cockroaches in your home is the use of chemical baits or insecticides. Not every person feels comfortable using insecticides inside their home, particularly families with small children that might inadvertently ingest said insecticides. If this is the case, then there are non-chemical methods of controlling cockroaches available for use instead. Their success rate depends a lot on the extent of an infestation, and are usually recommended for use in conjunction with other control techniques such as making your home clean and less hospitable to cockroach pests in a number of ways. These non-chemical control methods are also often used together with chemical insecticides to treat larger infestations.

If you are dealing with a light infestation, sticky traps with or without pheromone lures can be used to control cockroaches. These can be placed anywhere cockroaches have been spotted or detected, as well as areas that attract the pests such as kitchens and bathrooms. These traps must be monitored frequently to check for full or old traps that need to be replaced. You can also make your own simple trap out of a glass jar. You first want to glue or tape a paper towel around the outside of the glass jar, so the cockroaches have a rough enough surface they can climb up the jar, which they will then fall inside once they reach the top. To keep the cockroaches from getting out, line the inner lip of the jar with petroleum jelly. Place a piece of bread soaked in beer or another food item that will actively draw cockroaches inside the jar. Finally, place the jar upright in a cabinet, on the floor in the kitchen or anywhere else you have seen them, and leave it there overnight to attract some unlucky roaches. When you check it in the morning, if you find some cockroaches, they can be killed by closing the jar and placing it in the freezer or filling it with water and detergent.

Another non-chemical control method is using temperature to kill the pests. Cockroach pests can be eliminated through heat treatments. However, this only works if you are able to heat the entire room or apartment to around 140-150 degrees Fahrenheit for 5 to 6 hours straight. Cold treatments are used effectively on smaller infested items. The object must stay at a temperature below 0 degrees Fahrenheit continuously for at least several days in order to eliminate all cockroach pests, including nymphs and oothecae.

A Recent Government Study On The Frequency Of Insect Pest Issues Within US Cities Found That Cockroach Infestations Are Most Prevalent Within New Orleans

Certain cockroach species benefit from living in close association with humans, and it has historically been assumed that all cockroach pests found within homes are nothing more than an ugly nuisance. However, this is no longer the case, as a growing amount of scholarly literature demonstrates that roach pests radiate bodily matter that contributes to the development of asthma when this matter is inhaled. If that is not enough, it is well known that common cockroach pest species are covered in more than 30 different types of disease-causing microorganisms, including bacteria, fungi, molds, and a couple of viruses. Also, researchers have recently found indoor cockroach pest species carrying an amoeba that causes dysentery, another parasite that causes giardiasis, and the poliovirus. Unfortunately for New Orleans residents, a recent study carried out by government researchers has revealed that cockroach infestations are most frequent in New Orleans when compared to all other US cities.

Every other year, Federal employees carry out the American Housing Survey, which asks people all over the US questions about housing satisfaction, the interior conditions of their home, and which, if any, pests have been problematic within or near their home, including insect, arachnid, and wildlife pests. Although the four primary cockroach species in the US infest homes in all US states, the housing survey almost always finds that cities located near oceans and other bodies of water see the highest rate of cockroach infestations. It probably won’t come as a surprise to residents of the Big Easy to learn that their historically notable home city is the most cockroach-infested metropolitan area in the country. However, residents of New Orleans may be shocked to hear that more than 41 percent of residents in the city have encountered cockroach pests within the past year. This is due to New Orleans’ subtropical geographic location, outdated urban and residential structures, and the city’s crude infrastructure, specifically the city’s anachronistic sewer system, which was constructed before the arrival of the 20th century.

Oriental Cockroaches Are Uniquely Well Suited For Thriving Within Southern Homes, And The Infestations They Establish Within Homes Are Becoming More Extensive

Several cockroach species are common household pests throughout Louisiana, including American, German, Oriental, Australian, Turkestan, Surinam, smokybrown, and brown-banded cockroaches. Many experts state that the Oriental cockroach is more capable of thriving indoors in the southern states than any other cockroach species found in the region. This may be due to the Oriental cockroaches’ ability to thrive in dry and cool indoor areas as well as moist and hot indoor areas. Historically, Oriental cockroach infestations were largely limited to basements, crawl spaces, cellars, and high-moisture areas on the ground floor of homes. However, this roach has been changing its habits in recent years, as they are now being found throughout homes, including the uppermost floors and attics. The Oriental cockroach is also the roach pest that is most frequently associated with “cockroach odors,” which are usually musty smelling and unpleasant.

Oriental cockroaches are dark brown to black and relatively large, as male and female adults are between 1 and 1 ¼ inches in length. Males and females cannot fly, and males have short wings that cover ¾ of their body, while female wings are nearly non-existent. Oriental cockroaches can typically be readily identified by their slow and sluggish movements, and they are abundant on residential lawns, making it common for one or a few specimens to wander indoors in search of food. Because of this, finding a small number of Oriental cockroaches indoors does not mean that an infestation has been established. Unlike domestic cockroach species that dwell primarily indoors, Oriental cockroaches generally prefer outdoor habitats, but they often invade homes through crawl space openings and along pipelines when outdoor conditions become unfavorable.

Pest control professionals sometimes apply an insecticide barrier around the perimeter of homes to prevent Oriental cockroach invasions. In many infestation cases, insecticide is usually applied to exterior foundation walls, especially around pillars, pipes, porches, and supports where the most common entry points are located. Several low-toxic control methods are also useful for controlling Oriental cockroaches, such as gel baits and bait stations containing boric acid and fipronil. Insecticide dusts like diatomaceous earth (DE) and silica aerogel are often used to kill Oriental cockroaches within wall voids, and DE is virtually non-toxic. Keeping outdoor vegetation well groomed, and keeping all plants and mulch a foot or more away from exterior foundation walls will make properties less attractive to Oriental cockroaches. Of course, sealing cracks, crevices and other potential entry points on exterior walls will prevent pests of all sorts from accessing interior living spaces.

How To Recognize Brown Cockroaches And Their Eggs

There are four primary cockroach species that infest homes throughout the United States. These species are commonly known as America, German, Oriental and brown-banded cockroaches. In addition to these four species, several additional cockroach pests can be found in the southeast where the subtropical climate favors roach activity. For example, the non-native species commonly known as smokybrown cockroaches, Australian cockroaches, and Surinam cockroaches can only be found in the Gulf Coast states. Periplaneta brunnea is another non-native cockroach species that can only be found in tropical and subtropical locations including Louisiana. This species is more commonly known as the “brown cockroach,” and its relatively large size can be unsettling to homeowners who find these pests indoors.

The brown cockroach is similar to the American cockroach in both appearance and behavior, but only the latter can be found throughout the country. Adult brown cockroaches are between 1.5 and 2 inches in length, and are reddish-brown in color. Much like American cockroaches, brown cockroaches possess a yellowish band directly behind their head on their upper back, but unlike American cockroaches, brown cockroach wings do not extend beyond their abdomen. Although the American cockroach is the second most commonly managed roach species within homes and buildings in the US, the brown cockroach is a surprisingly more common pest of homes in certain areas of the south. This may be due to the unusually rapid rate at which brown cockroaches proliferate in moist and humid conditions in the south.

The brown cockroach egg case, or “ootheca” is 12 to 16 mm long, and they are 5.2 mm longer than the average ootheca produced by female American cockroaches. The number of eggs within a brown cockroach ootheca varies from 21 to 28, and eggs develop into adults within 339 to 360 days, far shorter than the American cockroach life cycle. Female brown cockroaches use a frothy white oral secretion to paste their eggs to walls within protected locations, such as dark and moist harborages, beneath sinks, behind appliances, in basements, and within wall voids in bathrooms and kitchens. Initially, an ootheca appears brown in color, but they become progressively darker with age.
