I was very pleased with our pest service today. We were having an issue with ants in a couple areas. With the treatment and stop back by Mike as well as some suggestions on sealing them out, so far so good.

Get Rid of Oriental Cockroaches with Professional Roach Control that Goes Beyond Spraying
Killing the roaches you see won't address the gaps, moisture, and hidden harborage that may be keeping them around. Contact Impact Pest Control for targeted Oriental cockroach control built to tackle the source.
How to Get Rid of Oriental Cockroaches
If you’ve found a dark, almost black cockroach crawling around a basement, bathroom, garage, crawl space, or floor drain, you may be dealing with an Oriental cockroach. Sometimes called a “water bug,” this species is strongly associated with cool, damp environments and is often found near sewers, drains, plumbing, and moisture-damaged areas.
Oriental cockroaches are slower than many other roach species, but that doesn’t make them easier to control. They can enter from outside, travel through plumbing and crawl spaces, and establish harborage in areas that stay damp.
At Impact Pest Control, we identify where Oriental cockroaches are coming from, treat active areas, and address the moisture and entry points that allow them to keep returning.

Different cockroach species behave differently, which is why correct identification is critical for effective treatment.

What Makes Oriental Cockroaches Different?
Oriental cockroaches (Blatta orientalis) are easy to distinguish from many other common roaches once you know what to look for. Adults are typically about 1 to 1¼ inches long with a dark brown to nearly black body and a glossy, greasy-looking appearance. They are also relatively slow-moving and cannot fly.
Their habitat is the bigger clue. Oriental cockroach infestations are often connected to a combination of moisture and access.
Unlike other types of cockroaches, which commonly establish themselves in warm kitchens and bathrooms, Oriental cockroaches favor cool, damp, dark areas near ground level. They can be found around floor drains, crawl spaces, sewers, leaking plumbing, mulch, leaf litter, and other areas with high moisture.
This means an Oriental cockroach problem may have more to do with what's happening beneath or outside your home than what's happening in your kitchen.
Start ServiceMoisture Creates The Habitat They Need
Leaking pipes, poor drainage, wet crawl spaces, clogged gutters, and other moisture problems can make a property much more attractive.
Entry Points Connect Outside To Inside
Cockroaches can enter under doors, through foundation cracks, around utility pipes, through vents, and along plumbing routes. Sealing these openings is an important part of long-term control.
Drains Can Provide A Pathway
A properly maintained P-trap creates a water barrier, but dry or poorly maintained drains can provide easier access between sewer-connected areas and the building.
How Professional Oriental Cockroach Control Works
Step 1: Inspect Moisture-Prone Areas
We inspect kitchens, bathrooms, garages, crawl spaces, utility areas, floor drains, plumbing penetrations, and the exterior perimeter to identify where cockroaches are hiding and how they're getting inside.
Start Service
Step 2: Locate Entry Points And Harborage
Our technicians look for cracks, gaps beneath doors, plumbing openings, drainage issues, moisture-damaged areas, and outdoor harborage near the foundation.

Step 3: Apply Targeted Exterior Roach Treatments
Effective Oriental cockroach pest control isn't simply about spraying the roaches you see. The treatment needs to address the conditions and pathways supporting the infestation. We treat active harborage and travel areas using professional products selected for the conditions and species involved. Exterior perimeter treatments can also help reduce the number of Oriental cockroaches moving toward the structure. Extension guidance supports perimeter treatments and baiting as part of Oriental cockroach management.

Step 4: Apply Gel Bait And Targeted Treatments
Professional cockroach gel bait can be placed in protected areas where roaches travel and feed. Targeted spray treatments may also be applied to appropriate interior and exterior areas based on what the inspection finds.

Signs You Have An Oriental Cockroach Problem
Dark Roaches Near The Floor
Finding large, dark roaches along baseboards, floors, garages, or lower-level areas is a common warning sign.
Cockroaches Around Drains
Repeated activity near floor drains or plumbing fixtures may indicate a route into the structure.
Activity In Damp Areas
Roaches around leaking pipes, wet crawl spaces, or moisture-damaged areas suggest conditions that favor Oriental cockroaches.
Egg Cases In Hidden Areas
Brown, purse-shaped egg cases may be attached in protected locations where they are difficult to notice.
Musty Or Oily Odors
A strong odor can develop when a population becomes established.
Roaches Appearing After Rain
Changes in outdoor moisture can alter cockroach movement, sometimes driving them toward structures in search of more favorable shelter.
Why Oriental Cockroaches Keep Coming Back
Oriental cockroach infestations are often connected to a combination of moisture and access.
Moisture Creates The Habitat They Need
Leaking pipes, poor drainage, wet crawl spaces, clogged gutters, and other moisture problems can make a property much more attractive.
Entry Points Connect Outside To Inside
Cockroaches can enter under doors, through foundation cracks, around utility pipes, through vents, and along plumbing routes. Sealing these openings is an important part of long-term control.
Drains Can Provide A Pathway
A properly maintained P-trap creates a water barrier, but dry or poorly maintained drains can provide easier access between sewer-connected areas and the building.
Keep Oriental Cockroaches Out
Long-term prevention starts by making your property less attractive and harder to enter.
Fix Plumbing Leaks
Repair leaking pipes, faucets, drains, and other sources of persistent moisture.
Keep P-Traps Filled
Maintain water in plumbing traps to help prevent cockroaches from moving through drain connections.
Seal Foundation Gaps
Close cracks and openings around plumbing, doors, windows, and utility lines.
Reduce Outdoor Harborage
Move firewood, debris, thick mulch, and other hiding places away from the foundation.
Improve Drainage
Make sure gutters and downspouts direct water away from the home instead of allowing moisture to collect around the foundation.

Start ServiceOriental Cockroach Control Frequently Asked Questions (FAQs)
Get your Oriental Roach pest control FAQs answered.
Start ServiceAre Oriental Cockroaches The Same As Water Bugs?
“Water bug” is a common nickname for Oriental cockroaches because of their strong preference for damp environments. However, the term can also be used for other insects, so identifying the actual species is important.
Do Oriental Cockroaches Come Up Through Drains?
They can. Oriental cockroaches are strongly associated with drains and sewer systems, and extension guidance specifically identifies floor drains as common entry points. Maintaining water-filled P-traps can help create a barrier against this type of entry.
Why Are Oriental Cockroaches In My Crawl Space?
Crawl spaces provide the cool, dark, humid conditions Oriental cockroaches prefer. Moisture from poor drainage, plumbing leaks, or condensation can make these areas even more attractive.
Are Oriental Cockroaches Dangerous?
Oriental cockroaches can carry disease-causing organisms on their bodies and may contribute to allergen exposure. Because they commonly move through sewers, drains, garbage, and decaying organic material, they can contaminate surfaces as they travel.
Can Oriental Cockroaches Climb Walls?
They are poor climbers on smooth vertical surfaces and tend to remain at or near ground level. This is another useful clue when distinguishing them from species that commonly move throughout upper portions of a building.
Why Do I See Oriental Cockroaches After Rain?
Changes in moisture can disrupt outdoor harborage and cause cockroaches to move in search of more favorable conditions. If activity repeatedly increases after wet weather, look for standing water, saturated soil, drainage problems, or openings around the foundation.
Are Oriental Cockroaches Common In Texas?
Yes. Texas A&M identifies the Oriental cockroach as one of the common cockroach species found in Texas. They are particularly associated with cooler, damp, ground-level areas such as crawl spaces and wet locations.
Don't Let Moisture Invite Roaches In
Oriental cockroaches thrive around damp areas, drains, crawl spaces, and foundations. Impact Pest Control can find the conditions attracting them and treat the areas where they're hiding.
