Cockroach Control | Behavior And Prevention Guide
German and Oriental Cockroach Control, Prevention, and Behavior Guide
Cockroach Control & Extermination Services in Illinois
Cockroaches are one of the most difficult household pests to eliminate without professional help. They reproduce rapidly, hide in hard-to-reach areas, and can pose health risks when infestations are left untreated. D&K Pest Control & Wildlife Removal provides professional cockroach control and extermination services designed to eliminate roaches at all life stages and prevent reinfestation.
Our approach focuses on proper identification, targeted treatment, and long-term prevention — not temporary fixes.
Why Cockroaches Are a Serious Problem
Cockroaches are more than just a nuisance. Once established, they can:
-
Contaminate food and surfaces
-
Trigger allergies and asthma
-
Spread bacteria and pathogens
-
Multiply quickly and spread throughout a structure
Because roaches hide in wall voids, appliances, cabinets, and plumbing areas, infestations often grow long before homeowners realize the severity of the problem.
Comparing Cockroach Species

German Cockroach (MOST COMMON & MOST PROBLEMATIC)
-
Where found: Kitchens, bathrooms, apartments, restaurants
-
Why they’re bad: Rapid breeders; hardest to eliminate without professional treatment
-
Size/color: Small, light brown/tan with two dark stripes behind the head
-
Key note: If you see one during the day, there are usually many more hiding

American Cockroach
-
Where found: Basements, crawl spaces, sewer systems, commercial buildings
-
Why they’re bad: Large, fast, intimidating; can spread bacteria
-
Size/color: Very large (up to 2 inches), reddish-brown
-
Key note: Often enters from sewers or damp areas rather than breeding inside walls

Oriental Cockroach (“Water Bug”)
-
Where found: Basements, floor drains, crawl spaces, garages
-
Why they’re bad: Thrive in moisture; associated with unsanitary conditions
-
Size/color: Dark brown to black, shiny
-
Key note: Slower-moving but a strong indicator of moisture problems

Brown-Banded Cockroach
-
Where found: Bedrooms, living rooms, behind electronics, upper cabinets
-
Why they’re bad: Spread throughout the home, not just kitchens
-
Size/color: Small, light brown with banding across wings
-
Key note: Prefer warm, dry areas—often overlooked at first
Signs of a Cockroach Infestation
You may have a cockroach problem if you notice:
-
Live roaches, especially at night
-
Roaches active during the day (often a sign of heavy infestation)
-
Small droppings that resemble pepper or coffee grounds
-
Egg casings in cabinets or near appliances
-
Musty or oily odors in kitchens or bathrooms
Seeing even one cockroach can indicate a much larger hidden infestation.
Why DIY Cockroach Treatments Fail
Store-bought sprays and foggers often:
-
Kill only visible roaches
-
Drive roaches deeper into walls and voids
-
Fail to eliminate eggs and nymphs
-
Cause infestations to spread further
Professional cockroach control focuses on eliminating breeding populations, not just surface activity.
