Three roaches turn up in Rahway homes. Oriental cockroaches are easy to pick out once you know what to look for:
| Oriental cockroach | American cockroach | German cockroach | |
|---|---|---|---|
| Color | Shiny black to very dark brown | Reddish brown with a lighter band behind the head | Light tan with two dark stripes |
| Size | About an inch | Larger, often 1½ inches or more | Small, about half an inch |
| Wings | Males: short wings; females: tiny wing pads. Neither flies | Full wings; can glide | Full wings; rarely fly |
| Where you see them | Basement floors, drains, laundry rooms, first-floor bathrooms | Basements, boiler rooms, sewers, steam pipes | Kitchen cabinets, behind appliances, bathrooms |
| Likes | Cool, damp, dark | Warm and damp | Warm, near food and water |
| Climbs walls? | Poorly — often found on floors and in tubs | Yes | Yes |
Big dark roaches upstairs in the kitchen cabinets are less likely to be oriental. See waterbug vs cockroach for more on the names.
| Time of year | What usually happens |
|---|---|
| Late winter | Few seen; some survive in drains, crawl spaces and under slabs |
| Spring | Activity climbs; adults and young start wandering out of drains and damp spots |
| Early summer | Peak time to see them in basements and laundry rooms |
| Late summer | Some move outdoors into mulch, leaf litter and wall voids |
| Fall | They push back inside toward warmer basements as nights get cold |
| After heavy rain | More sightings, as water pushes them out of drains and soil |
Seeing them in spring or after a storm doesn't always mean a huge infestation, but if you see young ones (smaller, wingless roaches) along with adults, they're breeding nearby.
Rahway grew up along the Rahway River, and a lot of its housing is older: two-family homes, colonials and Cape Cods with full basements, plus apartment buildings near the downtown and the train station. Older basements tend to have exactly what oriental cockroaches want:
Rahway is in Union County, farther from our Garfield base than our core Bergen, Passaic, Essex and Hudson towns. We serve Rahway with visits scheduled ahead, and same-day is sometimes possible. Our main cockroach page covers all the roach types we treat.
Drains are the number one source. Roaches live in the moist drain line and walk up when the trap dries out or the cover is loose.
Oriental cockroaches come in from soil and mulch around the house. Pipe penetrations and foundation cracks are their front door.
They hide under anything that stays damp and dark. Boxes on a basement floor give them shelter right next to the drain they came up from.
A licensed technician checks drains, sump pits, pipe gaps, crawl spaces, laundry and boiler areas, and the foundation outside, and finds where they're coming from.
Gel bait goes in the cracks, pipe gaps and damp spots they travel through, along with an insect growth regulator that stops young roaches from maturing.
We show you which drains, sump lids and leaks are feeding the problem and what to fix or cover.
Pipe penetrations, foundation cracks and door gaps are marked so they can be sealed.
We come back to check and re-treat as needed. Roach treatment carries a 90-day warranty.
No fogging the whole house: foggers don't reach drains and wall voids, and they make bait less effective.
Pour water into floor drains and unused laundry drains every week or two so the trap stays full.
Use a tight-fitting sump pit lid and keep the area around it dry.
A dehumidifier in a damp basement makes it much less inviting.
Keep mulch, leaves and wood piles a foot or more away from the foundation.
These steps work best alongside treatment. Store-bought sprays mostly kill the roaches you see and can push the rest deeper into wall voids.
In apartment buildings, oriental cockroaches usually live in the basement, boiler room, trash area and drain lines, and wander up to first-floor units. Treating one apartment rarely solves it because the source is in the shared spaces.
Our apartment building pest control page and landlord and tenant guide explain more, in general terms.

They're shiny black or very dark brown and about an inch long. Males have short wings that don't cover the whole body, and females have only small wing pads. Neither can fly. They move slower than German roaches and are mostly seen on floors, in tubs and near drains.
They come for cool, damp, dark spaces. Most enter from floor drains, sump pits, crawl spaces and gaps around pipes, or wander in from mulch and leaf litter against the foundation. Basements with high humidity or dry drain traps are the most common places we find them.
Many people call them waterbugs because they show up near drains and water. A true water bug is a different insect that lives in ponds. The big black roach in your basement is almost always an oriental cockroach.
Most homes see a big drop within a few weeks of treatment, especially once drains and moisture are fixed. Because their egg cases hatch over time, we come back for a follow-up visit, and roach treatment carries a 90-day warranty.
Some do. They can live in drain and sewer lines and walk up through floor drains when the trap water dries out. Keeping drains filled with water and covers tight is one of the best things you can do.
We place gel bait and growth regulator in cracks, gaps and hiding spots instead of spraying open rooms, which keeps the product away from where kids and pets spend their time. Tell us about any health concerns and we'll plan around them.
You can help a lot by keeping drains wet, covering the sump, running a dehumidifier and pulling mulch away from the house. Sprays alone rarely fix it, because the roaches breed in drains and wall voids you can't reach.
