Three roaches, three different problems
German cockroach — about half an inch, light brown, with two dark parallel stripes behind the head. Lives only indoors: kitchen cabinets, under sinks, inside appliance motors and hinges. Breeds faster than any other household roach, and each egg case carries dozens of nymphs. This is the apartment-and-restaurant roach, and it is a program, not a visit: treatment, follow-up on the hatch cycle, and sanitation working together.
American cockroach — the big one, up to two inches, reddish-brown with a pale margin behind the head. Lives in drains, sewers, crawl spaces, and irrigated landscaping; comes indoors for water, especially during and after monsoon rains. Seeing one occasionally is an outdoor-population problem; seeing them daily means a drain or void population is established.
Turkestan cockroach — an outdoor species now widespread across El Paso and the desert Southwest. Males are dark and fly to lights; females are dark with cream banding and can't fly. They mass in garages, meter boxes, block-wall voids, and around exterior lighting, then drift indoors. Largely replacing the old oriental cockroach outdoors, they are the species behind many 'my garage is full of roaches' calls.
Why El Paso roaches peak with the monsoons
From July through September, monsoon downpours flood the arroyos, storm drains, and ground-level harborage that American and Turkestan roaches live in. The survivors move up and in — through door gaps, weep holes in the brick and stucco, and pipe penetrations — at the same time indoor humidity peaks. The mild desert winter never fully resets outdoor populations, so each year starts from a higher base than the last unless a barrier is maintained.
What professional treatment does differently
- Species ID first. The whole plan hangs on it — baits and growth regulators for German roaches; drain, void, and perimeter work for the outdoor species.
- Harborage treatment, not baseboard theater. Products go where roaches actually live: cracks, voids, appliance bays, meter boxes, and drain entries.
- Exclusion. Door sweeps, sealed plumbing penetrations, and screened vents cut the re-entry routes monsoon season exploits.
- Follow-up on the biology. Egg cases hatch on a cycle; a real German roach program is scheduled around it.

Roach FAQ — El Paso
Which roach do I have — and why does it matter?
German cockroaches (small, tan, two dark stripes behind the head) live indoors and breed in appliances and cabinets — they need a real multi-visit program. American cockroaches (large, reddish-brown) live in drains, sewers, and landscaping and wander in. Turkestan cockroaches (outdoor, dark males and banded females) mass around lights and garages. The species decides the treatment; treating an outdoor species as an indoor one wastes your money.
Why do roaches surge after monsoon rain?
Rain floods the drains, arroyos, and ground harborage roaches live in and drives them upward and inward at the same moment humidity makes indoor conditions ideal. July through September is El Paso's roach season for exactly this reason.
I keep my kitchen clean. Why do I still have roaches?
Clean helps enormously with German roaches — grease and crumbs are their fuel — but American and Turkestan roaches live outside and enter for water and shelter. Exclusion (door sweeps, sealed pipe penetrations) and exterior treatment matter as much as sanitation for those species.
Are the roaches in my garage a problem?
They're a staging area. Garage populations around water heaters, washers, and stored cardboard move into living spaces as numbers grow. Turkestan roaches especially build large outdoor populations in El Paso garages and meter boxes before appearing indoors.
