Are you having issues with cockroaches? These bugs can still be unsettling and lead to a variety of issues. Learn everything you need to know to get rid of them.

What Are Cockroaches?

Cockroaches are insects that belong to the order Blattodea. They are among the most primitive and resilient insects on Earth and have been around for millions of years. There are thousands of species of cockroaches, but the most common ones that interact with humans include the German cockroach, American cockroach, Oriental cockroach, and the brown-banded cockroach.

Here are some key characteristics and facts about cockroaches:


Cockroaches typically have flattened, oval-shaped bodies with long antennae and six legs. They are usually brown or black in color, but their appearance can vary depending on the species.


Cockroaches are highly adaptable and can be found in a wide range of habitats, including forests, grasslands, caves, and human-made structures such as homes, restaurants, and sewers.


Most cockroach species are nocturnal, which means they are active at night and rest during the day. They are known to scavenge for food in the dark.


Cockroaches are omnivorous scavengers and will eat a variety of organic materials, including food scraps, decaying matter, and even some types of glue or paper.


Cockroaches reproduce quickly, with females typically laying egg cases called oothecae. Each ootheca contains multiple eggs, and once they hatch, young cockroaches, called nymphs, go through several molts before reaching adulthood.


Cockroaches are renowned for their ability to survive in harsh conditions. They can endure extreme temperatures, survive without food for long periods, and are resistant to many chemical pesticides.

Disease Carriers

Cockroaches are not directly responsible for spreading diseases, but they can carry bacteria and pathogens on their bodies and in their feces. This can contaminate food and surfaces, potentially leading to health concerns.

Pest Control

Due to their association with unsanitary conditions and potential health risks, cockroaches are often considered pests and are a common target for pest control efforts.

Cultural Significance

Cockroaches have played roles in mythology, literature, and popular culture, often symbolizing filth, persistence, or resilience. They have also been used as subjects in scientific research, including studies on locomotion and robotics.

Ecological Roles

In natural ecosystems, cockroaches serve as decomposers, helping to break down dead plant and animal matter. They play an important role in nutrient cycling.

Are Cockroaches Dangerous?

Cockroaches themselves are not inherently dangerous to humans, but they can pose health risks indirectly due to their behavior and habits. Here are some reasons why cockroaches can be considered a potential health concern:

Disease Carriers

Cockroaches are known to carry and spread bacteria, viruses, and pathogens on their bodies and in their feces. When they come into contact with food, utensils, or surfaces, they can contaminate these items, increasing the risk of foodborne illnesses such as salmonella and E. coli.


Cockroach droppings, shed skins, and saliva contain proteins that can trigger allergic reactions and asthma in some individuals. People with allergies or respiratory conditions may experience worsened symptoms when exposed to cockroach allergens.

Asthma Triggers

Cockroach infestations in homes can lead to an increase in asthma attacks, especially in children. The allergens they produce can exacerbate asthma symptoms.

Unsanitary Habitats

Cockroaches are often found in unsanitary environments, such as sewers and garbage areas, where they can pick up harmful bacteria and pathogens. When they enter homes and other human spaces, they can transfer these contaminants.

Food Contamination

Cockroaches are scavengers and will feed on a wide range of materials, including food scraps and organic matter. Their feeding habits can result in contamination of food and food preparation surfaces.

Psychological Stress

A cockroach infestation can cause psychological stress and anxiety for people living in affected areas due to the associated stigma and feelings of uncleanliness.

Why Do I Have a Cockroach Problem?

A cockroach problem can occur for several reasons, and understanding the factors contributing to the infestation can help you address the issue effectively. Here are some common reasons why you might have a cockroach problem:

Food and Water Sources

Cockroaches are attracted to sources of food and water. If you have open food containers, crumbs, dirty dishes, or leaks in plumbing fixtures, it can provide a hospitable environment for cockroaches.

Poor Sanitation

Cockroaches thrive in unsanitary conditions. Clutter, garbage, and neglected cleaning can create hiding spots and food sources for these pests.

Cracks and Gaps

Cockroaches can enter buildings through small cracks, gaps, and openings. Insufficient sealing around doors, windows, pipes, and vents can make it easier for them to get inside.

Warmth and Shelter

Cockroaches seek warm and sheltered areas to hide during the day. They often inhabit dark, hidden spaces like cracks in walls, behind appliances, and in cabinets.

Previous Infestations

If your home or building has had a previous cockroach infestation that was not completely eradicated, residual eggs or nymphs may hatch and lead to a recurring problem.

Neighboring Infestations

If nearby homes or buildings have cockroach problems, these pests can migrate to your property in search of food and shelter.  


Some regions have climates that are conducive to cockroach infestations. Certain species of cockroaches are more prevalent in specific geographic areas.

Pet Food and Water

Leftover pet food and open water bowls can attract cockroaches. Make sure to store pet food in sealed containers and clean up any spilled water promptly.

Lack of Pest Control

Regular pest control and maintenance can help prevent cockroach problems. If you neglect pest control measures, cockroaches may proliferate.

Travel and Infested Items

Cockroaches can also hitch a ride into your home through infested items brought from outside, such as used furniture, boxes, or bags.

What Are Signs of a Cockroach Invasion?

Detecting the signs of a cockroach invasion early is crucial for prompt and effective pest control. Here are some common signs that you may have a cockroach problem:


The most obvious sign of a cockroach infestation is actually seeing cockroaches, especially during the daytime. Common hiding places include kitchens, bathrooms, basements, and dark, damp areas.


Cockroach droppings, which resemble small, dark, cylindrical pellets or coffee grounds, may be found in areas where cockroaches are active. These droppings are often found along baseboards, in cabinets, and near food sources.

Egg Cases (Oothecae)

Cockroach egg cases, called oothecae, are purse-shaped capsules that contain multiple eggs. Depending on the species, they may be brown, tan, or white. Finding empty or hatched oothecae is a sign of an infestation.

Musty Odor

Cockroaches emit a distinctive, musty odor. If you notice an unpleasant, lingering smell in your home that you can't identify, it could be a sign of a cockroach infestation.

Smear Marks

Cockroaches leave behind smear marks or streaks on surfaces as they travel along walls and other objects. These marks are a result of the oily secretions on their bodies.

Shed Skin

Cockroaches molt as they grow, leaving behind exoskeletons. Finding these shed skins in and around your home is a clear indicator of their presence.

Damage to Food Packaging

Cockroaches may gnaw on food packaging materials, leaving behind small holes or chew marks. They can also contaminate food with their feces and saliva.

Nocturnal Activity

Cockroaches are primarily nocturnal, so you may not see them during the day. However, you might notice signs of their activity when you turn on lights at night.

Hiding Spots

Check for cockroach hiding spots in warm, dark, and hidden areas such as behind appliances, under sinks, in cracks and crevices, and in cluttered spaces.

Increased Allergy or Asthma Symptoms

If you or family members have unexplained allergies or asthma symptoms that worsen indoors, cockroach allergens might be a contributing factor.

Scratching Sounds

In some cases, you may hear scratching or rustling sounds, especially at night, as cockroaches move around.

What Are Common Myths About Cockroaches?

There are several myths and misconceptions about cockroaches that have persisted over the years. It's important to dispel these myths to have a better understanding of these pests and how to deal with them effectively. Here are some common myths about cockroaches:

Cockroaches Are Only Found in Dirty Homes

While cockroaches are often associated with unsanitary conditions, they can be found in clean homes as well. Although cleanliness can deter cockroaches, these insects are resourceful and can thrive in a variety of environments.

Cockroaches Can Survive a Nuclear Explosion

This myth exaggerates the resilience of cockroaches. While they are known for their hardiness and ability to withstand radiation better than some other creatures, they would not survive a direct nuclear blast.

Cockroaches Are Harmless

Cockroaches are not harmless; they can carry and transmit diseases, contaminate food, and trigger allergies. Their presence in homes can lead to health concerns.

Cockroaches Are Only Active at Night

While many cockroach species are primarily nocturnal, they can also be active during the day, especially if they're competing for limited resources.

Cockroaches Live Only in Warm Climates

While cockroaches are more common in warm, tropical regions, they can also be found in temperate climates. Some species are adapted to survive in colder environments.

Cockroaches Are Not a Problem in High-Rise Buildings

Cockroaches can infest high-rise buildings just as easily as they can infest houses. They can travel through plumbing and electrical systems to move between floors.

Cockroaches Are Indestructible

While cockroaches are hardy insects, they are not invincible. Pest control measures and proper sanitation can effectively eliminate infestations.

Crushing Cockroaches Is an Effective Way to Get Rid of Them

Simply crushing a cockroach is not an effective means of control. It's better to take a comprehensive approach, including sanitation and pest control methods.

Cockroaches Are Only Found in Old Buildings

Cockroaches can infest both old and new buildings. Their presence is not solely dependent on the age of the structure.

Boric Acid Is Safe to Use in Large Amounts

While boric acid can be an effective cockroach control method when used in moderation, using excessive amounts can be toxic to humans and pets. It should always be used with caution.

How Do I Get Rid of Cockroaches?

Getting rid of cockroaches can be challenging, but with persistence and the right approach, you can effectively eliminate an infestation. Here's a step-by-step guide on how to get rid of cockroaches:

Identify the Species

Determine the type of cockroach you're dealing with. This can help you tailor your approach since different species may have slightly different behaviors and preferences.


Cockroaches are attracted to food, water, and shelter. Start by thoroughly cleaning your home:

  • Clean up food crumbs and spills promptly.
  • Store food in airtight containers.
  • Empty the trash regularly.
  • Fix any leaks or plumbing issues.
  • Keep pet food and water bowls clean.
  • Declutter to eliminate hiding spots.

Seal Entry Points

Inspect your home for cracks, gaps, and openings that cockroaches can use to enter. Seal these entry points with caulk or weather stripping to prevent their access.

Remove Hiding Places

Cockroaches prefer dark, sheltered areas. Reduce their hiding spots by:

  • Clearing clutter in basements, attics, and storage areas.
  • Keeping your home well-organized and free of unnecessary items.
  • Sealing cracks and gaps in walls and floors.

Bait Stations

Place cockroach bait stations in strategic locations. These contain poison that the roaches take back to their nests, effectively eliminating the colony.

Gel Baits

Gel baits can be applied in cracks and crevices where cockroaches hide. They are attractive to roaches and can be effective in controlling the population.

Insecticidal Sprays

Use insecticidal sprays labeled for cockroach control. Apply them in areas where cockroaches are active, but be cautious when using sprays in kitchen areas.

Diatomaceous Earth

This natural powder can be applied in areas where cockroaches travel. It damages their exoskeleton and dehydrates them. Be sure to use food-grade diatomaceous earth if applied in kitchen areas.

Professional Pest Control

If the infestation is severe or persists despite your efforts, it's advisable to consult with a professional pest control service. They have the expertise and tools to effectively eliminate cockroach infestations.

Cockroach Pest Control Tips

Monitor and Repeat

Even after the initial treatment, continue to monitor for signs of cockroach activity. Repeat treatments as necessary, following the instructions on the products you use.

Prevent Reinfestation

Once you've eliminated the infestation, continue to practice good sanitation and maintenance to prevent future cockroach problems. Regularly clean, seal entry points, and consider ongoing pest control measures if necessary.

Remember that cockroach control may take time, and it's important to be persistent and thorough in your efforts. Additionally, always follow safety precautions and read and follow the instructions on any pest control products you use, especially when applying them in areas where food is prepared or near children and pets.
