Why do big cockroaches come up in older South Lawn homes?
Large cockroaches in older South Lawn homes are usually American cockroaches, which live mostly outdoors and in sewers and come up through floor drains, dry drain traps, gaps around old pipes and crawlspace openings. We treat drains, crawlspaces and the foundation, seal gaps around plumbing, and show you how to keep drain traps full. Smaller German cockroaches in kitchens need a different, bait-based plan.
Why older South Lawn bungalows give roaches a way up from below
South Lawn is one of south-central Amarillo's older neighborhoods, with 1940s and 1950s ranch homes and bungalows around South Lawn Elementary on S Bowie St, the Southlawn Park splash pad and S Washington St. Homes from this era were built with cast iron and clay drain lines, floor drains in laundry and utility rooms, and in some cases pier-and-beam floors over a crawlspace rather than a slab.
American cockroaches live mostly outdoors and in sewers. They are the big, reddish-brown roaches, about an inch and a half long, that show up in bathrooms and laundry rooms. They come up through floor drains, especially ones whose water seal has dried out, and through gaps where old pipes pass through floors and walls. A crawlspace with an open vent or a broken access door gives them another way in.
German cockroaches are a separate problem. They don't live outdoors in Texas and stay indoors near heat and water, usually in kitchens. Older South Lawn homes in the 79110 ZIP can have both, and it matters which one you have, because the treatments are different.

How we treat cockroaches in an older South Lawn home
We match the treatment to the cockroach, then close the routes they use.
Identify the cockroach
Our technician checks sticky monitors, droppings and any live roaches to confirm which kind you have and where they are active.
Work the drains
We inspect floor drains, laundry standpipes and tub drains. Dry traps get refilled, and we treat drain areas and gaps around old pipes where roaches enter.
Check the crawlspace
On pier-and-beam homes, we look at crawlspace vents and the access door, treat the crawlspace edges and point out screens or doors that need repair.
Bait the kitchen if needed
If German cockroaches are present, we place gel bait in cabinet cracks and add a growth regulator so the next generation can't mature.
Seal and follow up
We seal gaps around plumbing and return to check monitors, adjusting treatment where activity continues.
What South Lawn homeowners can do to keep roaches down
Most of these take a few minutes and help every treatment last longer.
- Pour a gallon of water into floor drains and unused tub drains every couple of weeks.
- Use drain covers or stoppers on drains you rarely run.
- Repair crawlspace vent screens and keep the access door closed tight.
- Fix dripping faucets and leaks under sinks and in the laundry room.
- Keep pet food sealed and wipe up spilled water bowls at night.
- Clear stored cardboard from utility rooms and crawlspace entries.

Pest control questions from South Lawn
Do big roaches in my South Lawn bathroom mean my house is dirty?
No. Large American cockroaches usually come from sewers and drains, not from anything you did. In older South Lawn homes, dry floor drains and gaps around old pipes give them an easy route up. Keeping traps filled with water, sealing pipe gaps and treating the drains stops most of them, no matter how clean the house is.
Should I worry about rodents in a South Lawn crawlspace?
It is worth checking. Crawlspaces under older pier-and-beam homes give mice and rats shelter close to the floor, and a house mouse needs only about a quarter-inch gap to get in. We look for droppings, nests and gaps on the same visit, then trap and seal so rodents can't use the crawlspace.
Are older South Lawn homes on pier-and-beam more likely to get termites?
They can be, because wood framing sits closer to the soil and piers give termites a path upward. Look for mud tubes on piers and foundation walls, and keep soil and debris away from wood. Our technician can inspect the crawlspace for termite activity during a cockroach visit.
