20+ Cockroach Facts That Will Make Your Skin Crawl! (Free Printables)

For millions of years, cockroaches have existed and evolved to become one of the most adaptable pests on the planet. Approximately 4,000 known living species, around 70 of which are found in the United States.

Unfortunately, their presence can cause allergies and asthma attacks, particularly in children, and spread to 33 different types of bacteria.

While most homeowners know cockroach infestations’ associated health and safety hazards, such as allergens and germs, what may not be common knowledge is that cockroaches exhibit peculiar behaviors and survival strategies, making them fascinating and resilient pests. 

Today, in this article, we will discuss some amazing cockroach facts.

Facts About Cockroaches:

Mostly Found in American Households

With over 4,000 cockroach species inhabiting various parts of the world, only 30 are considered problematic for humans.

Among the numerous species, the German, American, brown-banded, smoky brown, and oriental cockroaches are the most commonly encountered in households across the United States.

The Surprising Reality of Cockroach Cannibalism

Cockroaches are not selective in their diet and will consume various items such as fruits, glue, and even feces. Interestingly, they have been observed feeding on their own kind when hungry.

When food is scarce and cockroach populations are high, cannibalism becomes a viable option for these insects to obtain nourishment and decrease their numbers.

Existence of Cockroaches Are Millions of Years

While individual cockroaches may not live long, with the American cockroach having an average lifespan of only around one year, evidence suggests that these insects have been on Earth for an incredibly long time.

According to Penn State College of Agricultural Science, fossil records indicate cockroaches have existed for over 300 million years. This implies that even prehistoric humans had to contend with the problem of cockroach infestations in their dwellings.

Cockroaches Can Be Surviving Nuclear Explosions

The belief that cockroaches can withstand a nuclear blast is simply a misconception, although it does have some basis.

This myth originated in 1945 following the atomic bombings of Hiroshima and Nagasaki when it was reported that cockroaches were the only creatures to have survived the devastation.

None of these insects managed to endure the extreme radiation levels of 100,000 rads, but they are more resistant to radiation than humans and can endure higher levels.

Cockroaches Can Live Without Their Heads

Cockroaches can remain alive for about a week, even after losing their heads. This unusual ability is because, unlike humans, cockroaches do not rely on their mouths for breathing. Instead, they use tiny holes called spiracles in their bodies to take in oxygen.

Coupled with their capacity to survive without food for up to a month, cockroaches can persist without their heads for approximately seven days.

The Link Between Cockroaches and Allergic Reactions

Research has revealed that cockroaches can contribute to developing asthma and other allergic reactions.

According to the American College of Allergy, Asthma & Immunology, cockroach saliva, feces, and exoskeleton remnants can trigger asthma when dispersed into the air. 

Additionally, the Asthma and Allergy Foundation of America highlights that cockroaches harbor a protein that is an allergen for numerous individuals and can provoke asthma attacks.

Exploring the Incredible Speed of Cockroaches

Cockroaches are swift creatures with the ability to move at astonishing speeds. Their agility is a crucial defense mechanism against many predators.

These insects can run up to 1.5 meters per second (2), which is impressive. To put this in perspective, it’s the equivalent of a human running approximately 200 miles per hour.

Can Cockroaches Fly?

The common perception of cockroaches is that they can fly but cannot. While many species of cockroaches have wings, they are not developed enough to facilitate actual flight.

Rather, they are used for gliding and short fluttering distances, giving them the ability to “fall with style,” as Buzz Light-year would say. For cockroaches, running is much more efficient than attempting to fly.

Cockroaches’ Surprising Attraction to Beer

Research has revealed that these pests are drawn to the sugars and hops in beer and might be responsible for raiding your fridge for that cold pint. However, it’s not a sign that they’re partying; it’s just their instinctual attraction to the beverage.

Cockroaches Can Hold Their Breath for 40 Minutes

It is impressive that cockroaches can hold their breath for up to 40 minutes and survive underwater for about 30 minutes. Although it may seem impossible, scientific research has revealed this fascinating fact.

Cockroaches’ ability to hold their breath for an extended period is attributed to their ability to regulate water loss. They breathe through small tubes in their bodies called spiracles, which they also use to remove water vapor.

Role of Bacteria in Cockroach Survival

It may come as a surprise, but certain bacteria exist within the bodies of cockroaches that aid in their survival. These bacteria are genetically passed down to them and serve as a source of essential vitamins and amino acids.

In turn, the bacteria rely on the cockroach for sustenance. This symbiotic relationship enables cockroaches to thrive and survive on various food sources without needing nutrient-rich diets.

Aquatic Abilities of Cockroaches: Great Swimmers

Cockroaches have an impressive ability to swim, demonstrating how they have survived for centuries. Cockroaches can hold onto their breath for a long time, surviving underwater for up to 30 minutes.

The Gisborne Cockroach Is the Biggest Species in New Zealand

The Gisborne cockroach is the biggest species in New Zealand, and it has a flat, dark body with white bands on its sides, measuring up to 4.5cm in length.

In comparison, the South American Megaloblattalongipennis is the world’s largest cockroach, with a length of 9.7cm and a wingspan of 20cm.

The Reproductive Prowess of Cockroaches

Cockroaches have a high reproductive rate, so they are considered pests. A female cockroach can lay hundreds of eggs in her lifetime, with an average of 30 eggs per month during her peak period.

If cockroaches establish their presence in your home, their population can grow rapidly, making it crucial to address the problem through cockroach removal procedures as early as possible.

High-Speed Movement of Cockroaches

Cockroaches have a remarkable ability to move quickly over long distances. American and German cockroaches, in particular, can run at 5km per hour.

They also have the potential to spread disease, which can pose a significant problem for businesses, especially those in the food industry.

Cockroaches Have Existed for Over 280 Million Years

According to research, cockroaches have lived on Earth for over 280 million years, an incredibly long time. It’s no surprise that they are known to outlast humans.

One reason for their survival is their ability to reproduce in large numbers, with females laying 30 to 50 eggs six to eight times throughout their lifetime. 

Cockroaches can survive for at least a year, making them resilient to various environmental conditions.

The Pervasive Threat of German Cockroaches: Health Risks and Allergies

German cockroaches are the most prevalent type, and they can become adults as little as 36 days from birth.

Due to their widespread prevalence, it has been linked to outbreaks of sickness and allergic reactions in numerous individuals.

Surprising Speed and Elusiveness of One-Day-Old Baby Cockroaches

Despite being the size of a speck of dust, a baby cockroach that is only one day old can run at nearly the same speed as its parents.

This exceptional speed, combined with their small size, makes them difficult to catch and eradicate, which is particularly concerning as these pests are known to spread various diseases.

Sensory Abilities of Cockroaches

Cockroaches possess sensory organs and hairs on their legs that make them highly attuned to vibrations in their environment. As a result, they can detect when someone is approaching them and are often quick to flee before any actual contact is made.

So, when you try to sneak up on a cockroach, the insect has likely already sensed your approach and taken off to avoid being caught.
