Types and Breeds of Cockroaches, Their Appearance and Their Characteristics

Cockroaches are among the most resilient and adaptable pests found in homes, businesses, and public spaces across Kenya. Known for their ability to survive in diverse environments, these insects are a common nuisance in Nairobi and other urban areas. Understanding the types and breeds of cockroaches, their appearance, and their characteristics is crucial for effective pest control. This article by PestPro.co.ke explores the major cockroach species found in Kenya, detailing their physical traits, behaviors, and why professional pest control is essential for managing infestations.

Why Knowing Cockroach Types Matters

Cockroaches are not just unsightly; they pose health risks by spreading bacteria, contaminating food, and triggering allergies. Different species have unique habits and preferences, which influence the pest control methods needed to eliminate them. By identifying the type of cockroach in your home or business, PestPro can tailor treatments for maximum effectiveness, ensuring long-term protection.

Below, we discuss the most common cockroach species in Kenya, their appearance, and their key characteristics.

1. German Cockroach (Blattella germanica)

Appearance

• Size: 13–16 mm long (about the size of a small paperclip).
• Color: Light brown to tan with two dark parallel stripes running from the head to the wings.
• Body: Small, oval-shaped with long antennae and wings (though they rarely fly).
• Distinctive Features: The stripes on the pronotum (the plate behind the head) are a key identifier.

Characteristics

• Habitat: Prefers warm, humid environments like kitchens, bathrooms, and food storage areas. Commonly found in restaurants, hotels, and homes in Nairobi.
• Behavior: Nocturnal, highly reproductive, and fast-moving. A single female can produce up to 400 offspring in her lifetime.
• Diet: Omnivorous, feeding on food scraps, grease, and even non-food items like soap or glue.
• Health Risks: Known to spread pathogens like Salmonella and E. coli, contaminating surfaces and food.
• Control Challenges: Rapid reproduction and resistance to some pesticides make them difficult to eliminate without professional intervention.

2. American Cockroach (Periplaneta americana)

Appearance

• Size: 35–50 mm long (one of the largest cockroach species).
• Color: Reddish-brown with a shiny body.
• Body: Elongated, with fully developed wings that allow limited flight or gliding.
• Distinctive Features: A yellowish figure-eight pattern on the pronotum.

Characteristics

• Habitat: Thrives in warm, moist areas like sewers, basements, and drainage systems. Common in commercial buildings and urban areas of Kenya.
• Behavior: Nocturnal and capable of flying short distances in warm weather. They are fast runners, covering several meters in seconds.
• Diet: Feeds on decaying organic matter, food scraps, and starchy materials.
• Health Risks: Can carry bacteria and allergens, contributing to asthma and allergic reactions.
• Control Challenges: Their size and ability to hide in deep crevices require comprehensive treatments like fumigation or residual spraying.

3. Oriental Cockroach (Blatta orientalis)

Appearance

• Size: 20–30 mm long.
• Color: Dark brown to black, with a glossy appearance.
• Body: Broad, with short wings in males (covering only part of the body) and no wings in females.
• Distinctive Features: Slower and less agile than other species, with a more robust body.

Characteristics

• Habitat: Prefers cool, damp areas like basements, drains, and under sinks. Often found in ground-floor apartments and markets in Nairobi.
• Behavior: Less active than German or American cockroaches, often staying close to water sources. They are poor climbers.
• Diet: Consumes decaying matter, garbage, and starchy foods.
• Health Risks: Spreads bacteria and produces a strong, unpleasant odor that can linger in infested areas.
• Control Challenges: Their preference for damp environments requires targeted treatments in moisture-prone areas.

4. Brown-Banded Cockroach (Supella longipalpa)

Appearance

• Size: 10–14 mm long (smaller than German cockroaches).
• Color: Light brown with two lighter bands across the wings and abdomen.
• Body: Small, with wings that are more developed in males than females.
• Distinctive Features: The bands are most visible in nymphs and fade slightly in adults.

Characteristics

• Habitat: Prefers warm, dry areas like bedrooms, closets, and furniture. Common in Nairobi apartments and offices.
• Behavior: Nocturnal and highly mobile, often found in areas away from kitchens, unlike German cockroaches. They can jump when disturbed.
• Diet: Feeds on starchy materials, glue, and household items like wallpaper paste.
• Health Risks: Can contaminate surfaces and trigger allergies due to their shed skins and droppings.
• Control Challenges: Their tendency to spread out in non-food areas makes them harder to locate and treat.

5. Smokybrown Cockroach (Periplaneta fuliginosa)

Appearance

• Size: 30–38 mm long.
• Color: Uniform dark brown to mahogany, with a shiny body.
• Body: Slender, with fully developed wings that allow gliding.
• Distinctive Features: Lacks the yellowish markings of the American cockroach.

Characteristics

• Habitat: Found outdoors in warm, humid areas like gardens, tree bark, and under mulch. May enter homes in Kenya during rainy seasons.
• Behavior: Strong fliers, often attracted to lights at night. They are less common indoors but can infest attics or garages.
• Diet: Feeds on plant material, decaying matter, and occasional food scraps.
• Health Risks: Less likely to spread disease indoors but can still carry pathogens.
• Control Challenges: Outdoor populations require perimeter treatments and sealing entry points.

Key Differences and Identification Tips

Species	Size (mm)	Color	Habitat	Key Trait
German Cockroach	13–16	Light brown	Kitchens, bathrooms	Two dark stripes on pronotum
American Cockroach	35–50	Reddish-brown	Sewers, basements	Yellow figure-eight on pronotum
Oriental Cockroach	20–30	Dark brown/black	Drains, damp areas	Slow-moving, no wings in females
Brown-Banded Cockroach	10–14	Light brown	Bedrooms, furniture	Two light bands across body
Smokybrown Cockroach	30–38	Dark brown	Outdoors, attics	Uniform color, strong flier

To identify cockroaches, examine their size, color, and location. For accurate identification, contact PestPro for a professional inspection, as misidentification can lead to ineffective treatments.

Why Professional Pest Control Is Essential

Each cockroach species requires a tailored approach for effective control. At PestPro.co.ke, we use integrated pest management (IPM) strategies, combining:

• Inspection: Identifying the species and extent of the infestation.
• Chemical Treatments: Using PCPB-approved pesticides like pyrethroids, neonicotinoids, or insect growth regulators.
• Non-Chemical Methods: Sealing entry points, reducing moisture, and improving sanitation.
• Follow-Up: Monitoring and re-treating to prevent reinfestation.

DIY methods often fail due to cockroaches’ resilience and rapid reproduction. Professional services ensure safe, effective, and long-lasting results.

Cockroaches are a diverse group of pests, with species like the German, American, Oriental, Brown-Banded, and Smokybrown each presenting unique challenges.
