10 Things You Need to Know About Cockroaches for a Pest-Free Home

Cockroaches are one of the most common insects found in households worldwide. Despite being a nuisance to homeowners and businesses, there is a lot to learn about these insects.

From where they come from to their different types, this article will provide you with all that you need to know about cockroaches.

Where Do Cockroaches Come From?

Cockroaches can enter the house from the outside through cracks, crevices, or open windows. They can also hitchhike inside on boxes, luggage, or clothes.

However, the origin and evolution of cockroaches can be traced back to over 300 million years ago. Cockroaches have adapted to various habitats, including tropical forests, deserts, and cave systems.

They have an ancestral origin in the Carboniferous period, during which they evolved from somewhat simpler, but still aquatic ancestors. Cockroaches are known for their ability to survive in almost all conditions, including extreme temperatures and limited food resources.

Reproduction and Development of Cockroaches

Cockroaches reproduce by laying egg sacs that contain many baby cockroaches. A female cockroach can lay from 10 to 40 eggs in each sac, and she can produce several egg sacs throughout her life.

The baby cockroaches undergo several molts before reaching maturity, during which they shed their skins. Cockroach development from hatchling to an adult takes about six to twelve months, depending on the species, environmental conditions, and food availability.

Name Origins and Characteristics of Cockroaches

The name “cockroach” derives from the Spanish word “cucaracha,” which means “little bug.” The scientific name for cockroaches comes from the Latin word “Blattodea.” Cockroaches are nocturnal insects that prefer dark, warm, and moist environments to live. They have a flat body shape that enables them to squeeze into tight spaces.

They also possess long antennae, which help them navigate and detect the presence of food, predators, or other cockroaches.

Different Types of Cockroaches and Their Origins

Flying Cockroaches

The Smokybrown cockroach is a species found in Australia and Asia that can fly. They are outdoor species that are attracted to homes because of bright lights.

German Cockroaches

Understanding where they come from can also help in reducing infestation levels and prevent them from entering homes or businesses. People who live in areas where there are cockroaches should always keep their living spaces clean and tidy to avoid attracting these insects.

Cleaning up crumbs, fixing leaks, and sealing up cracks and crevices can significantly reduce the chances of an infestation. Can Cockroaches Enter Your Home Through Various Means?

Cockroaches are hardy insects that can find their way into homes through several means. While some of these means have been debunked as myths, others hold some truth.

Here are the most common methods through which cockroaches can enter your home and how you can prevent them.

Toilet Entry

Many people believe that cockroaches can enter a home through the toilet. However, this is impossible.

Cockroaches cannot survive in water and would drown before they could crawl up the plumbing. Therefore, you do not need to worry about cockroaches coming up through the toilet.

Drain Entry

Cockroaches can crawl through sinks, showers, and drain pipes. They are attracted to damp and moist areas because they require water to survive.

They can also use leaky pipes as entry points. Once in the drain, they can use the plumbing system to move around the house.

To prevent cockroaches from entering the drain, ensure there are no leaks, and the drain is kept dry. You can also close the drain when not in use or use a drain trap to prevent cockroaches from crawling up.

Air Conditioner Entry

Cockroaches can enter a home through air conditioners, especially if there is a drainage pipe that leads outside. The moisture accumulated in the AC unit attracts cockroaches, and they can crawl through the vents into your home.

To prevent cockroaches from entering the air conditioner, have the unit serviced regularly to ensure it is free from moisture. You can also seal any openings where the ducts connect to the exterior of the home.

Clothes Entry

Cockroaches can lay their eggs in luggage or clothes. When the clothes are brought into the home, the eggs will hatch, and cockroaches will find their way into the living space.

To prevent this, inspect your luggage before packing and shake out your clothes before bringing them into your home.

Air Vent Entry

Cockroaches can crawl into homes through air vents and ducts. They can make their way from the exterior of the home through the ducts and into the living space.

To prevent this, seal all gaps around the opening of the ducts. You can also install filters to prevent cockroaches from crawling through the vent.

When Do Cockroaches Come Out and Why? Cockroaches are nocturnal insects and come out mostly during the night.

They hide during the day because they are sensitive to light and prefer dark and moist areas. Cockroaches also have specific behavioral patterns that are dictated by various environmental factors.

Hibernation and Winter Behavior

During the winter, cockroaches tend to hibernate and survive on limited resources. They seek shelter in warm and dry areas and reduce their activity to conserve energy.

Cockroaches can also survive low temperatures by huddling together for warmth.

Summer Behavior

Cockroaches become more active during the summer because of the warm and humid weather. This is the time when they reproduce and forage for food.

You are likely to see more cockroaches during this time, especially if there are food sources available.

Cold and Rainy Weather Behavior

During cold and rainy weather, cockroaches seek shelter in warm and dry areas. If cockroaches find their way into your home, they will hide in crevices, cracks, and other dark and warm spaces.

Cockroaches can also drown in water, so they will avoid areas with standing water.

Hot Weather Behavior

Cockroaches seek shelter and water during hot weather. They become more active at night when the temperature is lower and search for food and water sources.

You are more likely to encounter cockroaches during this time around water sources such as bathrooms and kitchens.


Cockroaches are hardy and adaptable insects that can find their way into homes through several means. Understanding how they enter the house and their behavioral patterns helps to prevent an infestation and keeps your home cockroach-free.

By ensuring proper home maintenance and cleanliness, you can reduce the chances of a cockroach infestation and keep your home pest-free.

Methods to Get Cockroaches to Come Out of Hiding

Cockroaches are known to be elusive pests that can be difficult to find. They usually come out of hiding at night when they are searching for food and water.

However, there are several methods that you can use to get cockroaches to come out of hiding during the day.

Cockroach Baits

Cockroach baits are a common method to lure cockroaches out of hiding. These baits are designed to resemble food or are infused with sugar to attract the insects.

They come in different forms such as sticky paper, gel, or powder, and can be sprinkled in areas where cockroaches are likely to hide. Borax is a common chemical used in some types of commercial baits, which can be poisonous to insects.

Lamp and Light

Cockroaches are attracted to bright light, and a lamp can be an effective way of drawing them out of hiding. Turn off all other lights in the room and turn on a bright lamp to create shadows that cockroaches are attracted to.

This method is particularly useful in dark and damp areas like basements and attics.

Repelling Methods

Repelling methods for cockroaches involve using substances that drive them away from a particular area. One of the most common repelling methods is to place chopped onion in an area where cockroaches are likely to hide.

Boric dust can also be sprinkled in areas to kill cockroaches. A homemade mixture of sugar, baking powder, and flour can also be used to attract cockroaches before killing them.

Reasons Why Cockroaches Enter the House

Cockroaches enter homes for various reasons, including the availability of food, water, and shelter. Understanding why they come into the house can help in identifying an infestation and preventing it from happening in the future.

Motivation for Indoor Movement

Cockroaches are motivated to move indoors in search of resources, especially during the winter when food and water sources are scarce. They can also move indoors due to homelessness, such as when an outdoor environment becomes uninhabitable due to construction or climate changes.

Daytime Behavior

Cockroaches are nocturnal insects, but when there is an infestation, they can be seen during the day. This is because the population has increased, and the food sources are in short supply.

They can be found in dark and warm places, like inside cabinets and under kitchen sinks.

Nocturnal Behavior

Cockroaches are nocturnal insects, and they come out of hiding mainly at night. This is because they have evolved to avoid predators and other harmful factors that can impact their survival.

They are active when it is dark and quiet, looking for food and water.

Summer Behavior

Cockroaches become more active during the summer because of the warm and humid weather. They are attracted to food and water sources, which are ample during the summer.

They forage for food during the night and hide during the day when it is hotter.

Hot Weather Behavior

Hot weather causes cockroaches to become more active because of the abundance of food and water sources. They become more aggressive in foraging for food, and their reproductive rates increase.

During the day, they will hide in sheltered areas and only come out during the night to forage.


Cockroaches are tenacious pests that can find their way into homes and other buildings. It is important to understand the reasons why they enter the house and the different methods to lure them out of hiding and prevent an infestation from occurring.

By maintaining a clean and dry environment, homeowners can reduce the chances of a cockroach infestation and keep their home free from pests. In conclusion, cockroaches are adaptable pests that can enter a home in various ways and for different reasons.

Reproduction, food and water sources, and the need for shelter are the main drivers for cockroach behavior, making basements, kitchens, and bathrooms especially vulnerable to infestations. However, understanding their behavior patterns, motivations, and preferred hiding places can help homeowners prevent and eliminate cockroach infestations.

The use of baits, light, and repelling methods can lure cockroaches out of hiding and facilitate their removal. By implementing regular cleaning routines, sealing crevices and gaps, and ensuring proper hygiene maintenance, homeowners can keep cockroaches out of their home, promoting a healthy environment for their family and pets.
