How Do I get Rid Of German Cockroaches?

The German Cockroach is a common household pest that can quickly become a nuisance due to its rapid reproduction and adaptability. In order to control these pests effectively, your technician should have a thorough understanding of roaches in order to apply treatments properly. In this blog, we will delve into the lifecycle of these insects, explore DIY and professional control methods, and shed light on the potential dangers they pose to your home and health.




Lifecycle and Reproduction:

German Cockroaches undergo three main stages in their lifecycle - egg, nymph, and adult. Females can lay multiple egg cases throughout their lives, with each case containing around 30 to 40 eggs. The eggs hatch into nymphs, which gradually molt and develop into adults. The remarkable speed of their reproduction allows a small infestation to escalate rapidly.


DIY Control Methods:


Eliminate food sources by keeping your kitchen and dining areas clean. These include pet food, grease, and crumbs. Regularly vacuum and dispose of garbage promptly.

Sealing Entry Points:

Seal cracks and crevices in walls, floors, and cabinets to limit their access to your living spaces and eliminate harborage sites.


Over the counter dusts such as boric acid and diatomaceous earth are very popular. While these help, many people apply a very heavy dust which insects will actually avoid. Dusts should be applied very lightly. 

The Moisture Sweep:

This is a staple in our pest control program and we ask all of our customers to do this nightly. Depriving roaches of moisture leads to an increased attractant to our gel bait, helping you eliminate your problem faster. 

  • Dishwashing scrub pads, washcloths, sponges place in ziplock bag

  • Take paper towel and dry up sinks and counters. 

  • Dish drying rack or cloths need to be dried. 

  • Dry inside of dishwasher

  • Place coffee maker in room that roaches aren’t in or sealed container. 

  • Place dog bowls in location roaches aren’t in or in sealed container. 

Professional Control Methods:


Pest control professionals may use targeted insecticides to treat infested areas, ensuring a more effective and long-lasting solution. Treatment should include the use of an insect growth regulator to disrupt the lifecycle and prevent nymphs from becoming egg laying adults. 

Gel Baits: 

A form of professional insecticide, placed in strategic areas give the roaches exactly what they are looking for, food and moisture all in one. 


Using a HEPA filtered vacuum, professional can eliminate a large majority of the roach population, providing you fast relief. 


Professional dusts can be applied in areas that traditional sprays cannot reach. When applied properly, this will cause the roaches to come in contact with the dust, leading to death. 

Insect Monitoring Traps:

Also known as sticky traps, these will help catch live roaches and help prevent the reproduction of more roaches.  

Timely Treatments:

Due to the fast reproduction cycle of the German Cockroach, follow-up treatments should occur no longer than 2-3 weeks after your initial visit. A monthly program should be put in place as well until population is eliminated. 



Dangers and Health Hazards: Disease Transmission:

German Cockroaches are known to carry various pathogens and bacteria on their bodies and in their feces. As they move through different areas, especially unsanitary ones, they pick up these contaminants. When they come into contact with food, utensils, or surfaces in your home, they can transfer these harmful microorganisms, leading to the potential spread of diseases.

Asthma Triggers

Allergens and Asthma Triggers:

Cockroach droppings, shed skins, and saliva contain allergenic proteins that can trigger asthma and allergic reactions, particularly in sensitive individuals, children, and those with respiratory conditions. Prolonged exposure to these allergens can exacerbate existing respiratory problems or even lead to the development of new sensitivities.

Food Contamination

Food Contamination:

German Cockroaches are notorious for invading kitchen spaces, where they contaminate food and food preparation surfaces. Their scavenging habits make them carriers of pathogens that can cause food-borne illnesses. Consuming food that has come into contact with cockroach-contaminated surfaces can result in gastrointestinal issues and other health problems.

Cockroach Infestation

Rapid Reproduction and Infestation:

The fast reproductive cycle of German Cockroaches is a cause for concern. A small infestation can quickly escalate into a full-blown problem, making them challenging to control with DIY methods alone. Their ability to adapt to various environments and develop resistance to certain pesticides further complicates eradication efforts.


Psychological Impact:

Living with a cockroach infestation can have psychological effects on residents. The constant presence of these pests can lead to stress, anxiety, and a sense of discomfort in one’s own home. The fear of encountering cockroaches may affect daily activities and overall well-being.

Understanding the lifecycle, reproduction patterns, and control methods of German Cockroaches is crucial for effective pest management.
