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.

Everything You Need To Know About Cockroaches

Cockroaches are a pest found all over the world, being one of the most common in home infestations. They are active at night, scouring the kitchen, bathroom, garbage cans, and food storage places in the home for anything to eat. Due to their habits, and the chemicals that are released by their bodies, they will carry diseases and cause allergic reactions. As such, getting rid of these pests as soon as possible is highly recommended. In this article, we’re going to take an in-depth look at the roach and cover some of the things that you need to know about these insects.

Biology

Cockroaches are flat insects with two pairs of wings and a light brown to black coloration. There are over 4000 species of cockroaches in the world, with 55 of them being located in the US. Most cockroach species will rarely fly, despite having wings. Instead, they will choose to walk very fast as a means of travel. The most common species that infest homes in the US are the American, Australian, Oriental, German and brown-banded cockroaches.

Behavior

The species of cockroaches that are adapted to living indoors likely have tropical origins. This is why they are attracted to parts of the home where they can find food, warmth and moisture. They will live in large groups and they will be active at night, while hiding during the day in tight spaces such as crevices in furniture, door frames and walls. Some roaches may even hide inside appliances, televisions, or drains and sewer systems. You will notice that if you turn on the light and cockroaches are out in the open, they will soon scurry to dark locations where they feel safe.

Health effects

Cockroaches routinely travel from filth to food sources, spreading pathogens in their wake. They may spread diseases on food, book-bindings and fabrics. They also disgorge partially digested food, spread disease through their feces, and discharge a foul secretion from various glands on their bodies which makes infested areas have a particular odor. In terms of the diseases and adverse health effects that they can cause, you have diarrhoea, dysentery, cholera, leprosy, plague, typhoid fever and a variety of viral diseases. In addition to these, they also carry the eggs of parasitic worms and they are known to cause allergic reactions.

Getting rid of cockroaches

Like with any pest, it’s best to start by removing the causes of the infestation. Make sure that you keep all food in sealed containers, that you have a lidded garbage can, that you remove any entry points into the home such as cracks and spaces in the walls, and that you seal the openings around drain pipes and electrical cables. This is then followed by chemical control methods, usually employed by a professional. These methods are designed to eliminate all of the roaches in the home and clear out their nest. If you currently have a roach infestation, contact us today, and we will help you get rid of it.

How To Stop The Spread Of Cockroaches In Large Buildings

The German cockroach is one of the most “iconic” pests in the US. This cockroach, which originated from Asia, is known to spread dangerous diseases and trigger allergies and asthma reactions. Difficult to eradicate when it infests a single home, the German cockroach becomes a much larger problem when it infests a building with multiple residences, such as an apartment building.

Integrated Pest Management

When a large apartment building is infested, integrated pest management or IPM methods need to be applied, and in order to do this, the pest control specialist must understand how these insects congregate inside and between buildings. For starters, once roaches enter an apartment building, they will usually disperse within, but not traverse to a different building. They also tend to nest in kitchen areas, and if pesticides are applied in one apartment, but not in another, the roaches will simply move their nests to locations that do not have pesticides in them.

Infestation patterns in large apartment buildings

Roaches have an infestation pattern where they nest in apartments that share at least one wall. So if you have an infestation in an apartment building, odds are that so do some of your neighbors. This makes pest control a much more intensive process and it gives it a much larger scope. Think of this infestation pattern as radiating from a central point, where you have a heavy infestation in a number of core apartments, and as the distance grows from these apartments, the intensity of the infestation is lowered.

As such, in order to properly implement IPM for a large apartment building, pest control methods have to target all the apartments that have been infected. On top of that, measures should be set in place in order to prevent large scale infestations from recurring. These measures can take the form of programs that help spread instructions on how to keep the apartment clean, how to store food and how to keep clutter to a minimum in order to avoid infestations.

How effective is IPM long term?

Large apartment buildings are hard to keep pest free because of frequent resident turnover and the tolerance that some residents may have for cockroaches. Reinfestation is likely to occur. However, the frequency and intensity of infestations can be minimized using IPM and implementing regular building-wide pest control measures. For a smaller apartment building, the frequency of reinfestation can be even lower. If you are a building administrator and you have a cockroach problem, contact us today and we can help you set up a plan that will get the infestation under control.

The Four Strategies For Managing Cockroach Pests

Cockroaches are a major nuisance pest for most of the country, but it’s even worse in southern states like Louisiana due to their preference for moist, warm, and somewhat tropical habitats. Since they’ve become uniquely adapted to living amidst humans, they can become a serious household pest. They don’t merely pose an annoyance, though, as cockroaches are a source of allergens and pose an even bigger health threat to those people that have asthma. Knowing how to manage cockroach pests in your home is necessary when the pests have infiltrated our world to the point that they have.

The first strategy for controlling cockroach pests is preventing their presence from entering your home in the first place. This involves checking your home over for possible spots cockroaches could find their way in and sealing any crevices or cracks you may find in your kitchen, bathroom, exterior walls, doors, and windows. You may also need to make certain structural modifications to make your home such as using pipe collars and weather stripping. Even if you make sure your home is sealed tightly from the outside, you still will need to make sure your home is as inhospitable to cockroaches as possible. This involves using the second strategy for controlling cockroaches, which is sanitation. This is doing things around your house to deny cockroaches access to food, water, and shelter so they don’t want to settle in. You want to make sure to keep your home clean, particularly your kitchen where crumbs might be lying around or the food in your pantry and cupboards might not be in properly sealed and tight containers or your pet’s food might be left in its bowl for cockroaches to devour at night. You can eliminate possible shelter by making sure your home isn’t cluttered with papers, rags, or anything else that could become a convenient hideaway. Fixing things like plumbing leaks, drains, and sink traps will help eliminate any possible source of water for cockroaches.

If you have already found cockroaches in your home, there are two other strategies you can apply towards eliminating them. The first strategy is to trap cockroaches in your home using commercially available cockroach traps. These are most effective when placed against vertical surfaces, in corners, inside cabinets, under sinks, in the basement, and by floor drains. The last thing you can do to rid your home of cockroaches is to use chemical controls. You can find numerous commercially available insecticides and instructions on how to properly use them. This is probably the point when you might want to call in a pest control professional for some help as well.

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?
