How To Get Rid of Asian Roaches

Roaches 3

Asian cockroaches (Blattella asahinai) can be a nuisance in our homes and gardens. These small insects closely resemble German cockroaches, but they have unique characteristics and behaviors that set them apart. This comprehensive guide will provide you with all the information you need to understand Asian roaches, identify them correctly, and most importantly, get rid of them effectively.


To get rid of Asian roaches, first identify them by their light to dark brown color and attraction to light. They often reside outdoors in moist, organic areas. You can prevent infestations by maintaining a clean environment, eliminating potential habitats, sealing entry points, modifying exterior lighting, and scheduling regular pest control treatments. If infested, try home remedies like pellet baits and baking soda solution, or seek professional pest control services for more effective solutions.

Identifying Asian Roaches

Asian roaches are light to dark brown in color, with two parallel lines running behind their head on the pronotum. They can grow up to 5/8 of an inch long. Unlike German cockroaches, Asian roaches are strong fliers, thanks to their long and narrow wings. They are most active at dusk and are attracted to light, which distinguishes them from other roach species that scatter in the presence of light.

Common Habitats of Asian Roaches

Asian roaches prefer outdoor environments, particularly areas with moist, organic matter. You’ll often find them in mulch, compost piles, grassy areas, and shaded spaces with leaf litter. While they may occasionally enter homes, indoor infestations are rare. However, they are attracted to light sources, such as lamps and television screens, which may lead them indoors.

Health Hazards Associated with Asian Roaches

While Asian roaches are not as dangerous as other cockroach species in terms of disease transmission, they can still pose health risks. These roaches can spread more than 33 types of bacteria, including Salmonella and E. coli, contaminating food and surfaces. The allergens in their feces and saliva can also trigger allergies and asthma attacks.

Preventing Asian Roach Infestations

Prevention is always better than cure, especially when it comes to roach infestations. Here are some effective preventive measures:

  1. Maintain a clean environment: Regular cleaning can help reduce food sources for roaches.
  2. Eliminate potential habitats: Remove damp piles of leaves, keep grass short, and maintain a tidy yard.
  3. Seal entry points: Ensure windows and doors fit tightly and install mesh screens to prevent roaches from entering your home.
  4. Modify exterior lighting: Use yellow ‘BUG’ lights, which are less attractive to Asian roaches.
  5. Regular pest control treatments: Schedule regular pest control treatments to prevent infestations.

Home Remedies for Asian Roach Control

If you’re dealing with an Asian roach infestation, you can try the following home remedies:

  1. Pellet baits: Asian roaches are attracted to pellet baits, which can be spread widely outdoors.
  2. Baking soda solution: A mixture of water and baking soda can kill roaches if they drink it.
  3. Sealing cracks and crevices: Applying insecticide dust in cracks and crevices can help eliminate hiding roaches.

Remember, while these remedies can help reduce the number of roaches, they may not completely eliminate the infestation. In such cases, it’s best to consult a pest control professional.

Professional Pest Control Methods

Professional pest control services can provide effective solutions for Asian roach infestations. These include barrier treatments, baiting, indoor pesticide sprays, dusting cracks and crevices, and regular cleaning. They can also help you seal entry points and maintain your yard to prevent future infestations.

In conclusion, dealing with Asian roaches requires a good understanding of their behaviors and habitats, as well as an integrated approach combining preventive measures, home remedies, and professional pest control methods. With patience, persistence, and the right strategies, you can effectively get rid of Asian roaches and keep your home pest-free.
