What Are American Cockroaches and Palmetto Bugs?
How To Identify American Cockroaches and Palmetto Bugs
American Cockroach and Palmetto Bug Identification:
The American Cockroach has a shiny appearance with color variations from dark brown to reddish-brown colors with a prominent yellow band behind adults' heads. Juvenile American cockroaches share the same color variations; however, they have yellow markings on the abdomen and do not have fully developed wings. American cockroaches are anatomically very similar to most other cockroaches species, with their heads comprised of a mouth, eyes, salivary glands, and antennae. The American Cockroach have bodies that are flat and oblong. The American Cockroach, like other cockroach species, has an exoskeleton that protects its body.
Female Vs. Male American Cockroach Identification
Both Male and Female American Cockroaches have a similar visual appearance, and both can reach the same size in adulthood. The Male American Cockroach and the Female both have a Cerci at the top of the abdomens that help the American Cockroach to detect airflow, so the American Cockroach is aware of its surroundings. However, male American Cockroaches have a pair of styli on their abdomens, located between the cerci, unlike the Female American Cockroach. The Styli are smaller than the Cerci and can identify the Male American Cockroach from the Female American Cockroach.
American Cockroach Mating Procedure
American male and female cockroaches engage in heterosexual courtship rituals before mating. The Female American Cockroach begins the calling position, a courtship, by raising her wings, revealing her genital chambers, and releasing a male attracting pheromone who will flap his wings to show interest in her. As the male connects physically with the female in a rear-end to rear-end position, he will deposit sperm, starting the new American Cockroach life cycle.
What Is The Life Cycle Of American Cockroaches?
American Cockroach Eggs / Oothecae
Three to seven days after the American Cockroach mates, the female American cockroach produces Oothecas, a fancy scientific name for egg cases that contains roughly 15 embryos. The same American Female Cockroach will generate between six and fourteen total oothecae in her lifetime. After the Female American cockroach shelters, the egg case on the end of her abdomen for hours up to a couple of days time, the female deposits and attaches the oothecae in a discrete location with saliva that acts like glue.
American Cockroach Nymphs:
With Ideal conditions and optimal temperatures, The American Cockroach eggs will hatch within 24 - 38 days into nymphs, which are immature juvenile cockroaches. American Cockroach Nymphs undergo a metamorphosis, which will change their appearances as they grow into adulthood. As the American Cockroach grows, it will shed its exoskeleton after the molting process has reached 10 to 13 times, it will have reached maturity.
Adult American Cockroaches:
American Cockroaches, sometimes also referred to as a Palmetto Bug, reach around three inches long in adulthood, with some slightly exceeding 4cm in length. After the cockroach undergoes the final molt, the cockroach is then equipped with a set of wings and now has reproductive capabilities. The full process spans between six months to over a year. American cockroaches live for approximately one year.
Can American Cockroaches / Palmetto Bugs Fly?
American Cockroach Nymphs lack wings and are incapable of flight. However, adults have prominent wings and care capable of flight but prefer to scatter on foot quickly. American Cockroaches' flight is not a controlled flight like that of a Fly; it is more used to glide from higher locations to lower areas.
What Do American Cockroaches / Palmetto Bugs Eat?
The American cockroach has an omnivorous diet and will consume a wide array of foods and products. Cockroaches in a person's home will readily feed on glue, soap, book bindings, available food, and crumbs. However, in nature, the American Cockroach does serve as a beneficial insect that consumes organic matter and is responsible for recycling nutrients back into the environment.
American Cockroach / Palmetto Bugs, Natural Predators.
American Cockroaches / Palmetto Bugs are a nutritious food source; therefore, they are a delicacy to a vast host of birds, reptiles, insects, and amphibians. American cockroaches have been noted in the stomachs of frogs, birds, salamanders, and larger mammals such as monkeys and cats. Because American Cockroaches are known to carry parasites, bacteria, viruses, fungi, and protozoa, they can easily sicken hosts subject to direct contact or indirect contacts like cross-contamination from food or surface areas.
American Cockroach and Palmetto Bug Diseases
Cockroaches can spread various diseases. However, unlike fleas, ticks, and mosquitos, they do not directly pass pathogens unless the host consumes the insect or waste directly. Cockroaches are also known to be a significant contributor to asthma and streptococcus and staphylococcus. The transmission of diseases from American Cockroaches mostly occurs indirectly. Most Cockroach transmitted diseases are as follows.:
Cholera Transmission from Cockroaches
Cholera is an acute diarrheal infection caused by the Vibrio cholera bacterium. It is most common in underdeveloped countries with inadequate drinking water locations such as city municipal water supply or places that lack regulated clean water forcing its people to drink from possible contaminated sites like ponds, stagnant water locations, etc. Infection occurs through ingestion of contaminated water or food that has the bacteria present. If exposed, the American Cockroaches are subject to bacteria; the cockroaches will spread the bacteria through their fecal matter and regurgitation, resulting in the cross-contamination of surfaces and food.
The symptoms of cholera can vary from host to host. After the bacteria enters the small intestine, some may have no to mild symptoms. The most common symptoms noted are diarrhea, vomiting, and muscle cramps, as well as dehydration.
Gastroenteritis Transmission From Palmetto Bugs
Gastroenteritis is an inflammation of the intestinal lining caused by bacteria, a virus, or parasites. Viral Gastroenteritis takes the number 2 spot as one of the most common illnesses in the United States. Gastroenteritis caused by the Norovirus infection spreads from American Cockroaches / Palmetto Bugs from cross-contaminated food or water by contacting the cockroach who has walked through a contaminated location indirectly spread the virus to an unknowing host. Common symptoms of Gastroenteritis include cramps, nausea, low-grade fevers, and vomiting.
Leprosy Transmission From Cockroaches
Cockroaches and other insects are known carriers of the bacillus mycobacterium leprae, which is responsible for leprosy.
Cockroaches are capable of spreading leprosy through their feces. If left untreated, the leprosy bacteria can cause permanent damage to the victims' nerves, skin, and/or eyes. This can lead to disfigurement and deformities to the host infected. In most cases, cockroach cross-contamination is not usually known as the culprit since
Leprosy has an incubation period of roughly five years, with symptoms sometimes taking as long as 20 years to appear.
Salmonellosis Transmission From American Cockroaches
Like rats and other rodents, cockroaches also transmit the Salmonella bacteria responsible for salmonellosis, which affects humans with symptoms similar to food poisoning.
As Cockroaches feed on cross-contaminated food sources, the Salmonella bacteria remain in the cockroach's digestive system for a month, in some cases longer. The Salmonella bacteria are deposited through the cockroach's excrement or regurgitation.
Since the host can't see the bacteria, smell its presence, or taste the bacteria, it is not commonly traced back to Cockroaches. Salmonella's typical symptoms are diarrhea, fever, upset stomach and discomfort, and cramping in your belly.
Plague Transmission From Cockroaches
"The Plague" is often thought to be a rodent-borne disease from the transmission of Fleas. Although this is true, all cockroaches are suspected of spreading Yersinia pestis bacterium, which is known to cause the bubonic Plague. It is common for most individuals to think the Plague is a disease of the past; however, cases of this disease still turn up all of the time, with it being more common than most people think.
Bubonic Plague symptoms include, but are not limited to:
Swollen lymph nodes
Pain in the lymph nodes
Cramping of the muscles
Luckily, with advances in medicine, antibiotics introduced 24 hours after infection help to avoid severe consequences.
Campylobacteriosis Transmission From Cockroaches
Campylobacteriosis is another bacterial infection, this one caused by the campylobacter bacterium. This bacterial infection is a common foodborne illness. This bacteria has been found on the external exoskeleton surfaces of American cockroaches, Palmetto Bugs, and Oriental cockroaches.
The bacteria is transmitted through the ingestion of contaminated food sources and drinks such as undercooked poultry and contaminated drink sources.
Common symptoms of campylobacteriosis may result in cramps, abdominal pain, fevers, diarrhea, with some extreme cases causing blood in the stool. Campylobacteriosis typically requires little if any medical treatment and lasts 2-10 days on average.
Listeriosis Transmission From American Cockroaches
Listeriosis is a severe bacterial infection caused by a germ known as the bacterium listeria monocytogenes. This bacterial infection is usually contracted by cross-contamination from food or drinks.
Listeriosissemems to have a more pronounced effect on people with weakened or compromised immune systems. Women who are pregnant, elderly individuals, and newborns/ toddlers appear to be those most affected by Listeriosis. This does not mean that those whose immune systems are in excellent condition can not be affected by Listeriosis.
Symptoms of Listeriosis, like other bacterial infections, can vary. Some common symptoms are fever, diarrhea, and muscle aches, headaches, confusion, and in extreme cases, convulsions.
Dysentery Transmission From Cockroaches
Dysentery is another type of Gastroenteritis. Dysentery, however, results in diarrhea with blood in the stool. For most people, dysentery sufferers experience mostly mild symptoms, with recovery reported within a week roughly without seeking medical attention.
The two types of Dysentery are as follows:
Amoebic Dysentery: This Dysentery is caused by a parasite that is single-celled called entamoeba. This variation is most common in tropical locations.
Bacillary Dysentery: Bacillary Dysentery, also known as shigellosis, is caused by the shigella bacteria.
Both Dysentery variations are typically spread through unsanitary hand washing practices and the consumption of cross-contaminated food and drinks which contain the organism. Dysentery symptoms are diarrhea containing blood and mucus, nausea, stomach cramps with pain, vomiting, and a high-temperature fever.
Typhoid fever From Cockroaches
Typhoid fever, another type of bacterial infection, is caused by the salmonella typhi bacterium. This disease is highly infectious. Cockroaches become subject carriers of this disease by consuming feces that have been contaminated with the bacteria.
Typhoid fever is most common in underdeveloped countries that consist of poor sanitation and limited access to clean water. Typhoid Fever seems to affect the elderly or those with low immune systems, including children.
The symptoms of typhoid fever include, but are not limited to:
