It’s every homeowner’s nightmare: turning on the kitchen light late at night only to see a cockroach dart across the floor. The real question isn’t just “Why is it here?”—it’s “What kind of cockroach am I dealing with?”
In the Southeast, two culprits are most common: German cockroaches and American cockroaches. While they’re equally unwanted, these pests behave very differently, and knowing which type has invaded your home will determine how you get rid of them.
Why Identifying the Species Matters in 2025
Cockroaches aren’t just gross; they’re also a real health risk. In fact, recent studies link cockroach allergens to increased asthma attacks in children. Both German and American cockroaches can:
Carry bacteria like salmonella and E. coli
Trigger allergies and asthma symptoms
Contaminate food and surfaces
Reproduce faster than most homeowners can keep up with
But here’s the key: treatment strategies depend on the species. A German cockroach infestation spreads like wildfire indoors, while American cockroaches usually start outside before sneaking in. Misidentifying them can waste time and money on the wrong approach.
German vs. American Cockroaches: How to Tell Them Apart
Instead of memorizing a long list of differences, here’s what really matters to homeowners in 2025:
Where You’ll Find Them
German Cockroaches: Almost always indoors. They love warm, humid spaces like kitchens and bathrooms, and often hide inside appliances, wall voids, and even grocery bags brought inside.
American Cockroaches: Usually outdoors in mulch, sewer systems, and crawlspaces, but they come inside searching for food and water. You’ll spot them in basements, drains, and utility rooms.
> If roaches keep showing up in your kitchen, especially near appliances, it’s probably German cockroaches.
How Big They Are
German Cockroach: Small (about ½ inch), tan/light brown with two dark stripes behind the head.
American Cockroach: Large (1.5–2 inches), reddish-brown with a yellowish thorax. Sometimes called “palmetto bugs” in the South.
> If the roach is huge, you’re looking at an American cockroach.
How Fast They Multiply
German Cockroach: The worst offender. A single female can produce 30,000 offspring in one year. That’s why infestations explode seemingly overnight.
American Cockroach: Still prolific, but slower—around 800 offspring per year.
> If you’re seeing multiple roaches within weeks, German cockroaches are likely the cause.
Why Cockroaches Are So Hard to Eliminate
Whether German or American, roaches are survivors. They can live weeks without food, go days without water, and even withstand many DIY sprays. In fact, German cockroaches have developed resistance to some store-bought products, which makes infestations tougher than ever in 2025.
This is why professional pest control is the only truly effective solution. Pros not only identify the species correctly but also use targeted treatments designed for that cockroach’s behavior and breeding habits.
Targeted Cockroach Treatments from Yates-Astro
Because German cockroaches reproduce so quickly, they require a specialized treatment that’s different from standard pest control. At Yates-Astro Termite & Pest Control, we use targeted methods designed to eliminate German cockroaches at every stage of their lifecycle.
While general pest control services are effective for prevention and maintenance, they typically won’t eliminate an active German cockroach infestation on their own. That’s why we recommend a dedicated German roach treatment first, followed by a recurring general pest control service to help prevent future infestations.
If you’re dealing with a severe or widespread roach problem, our team can also provide additional treatment options, including fumigation when necessary, to completely eradicate the infestation and restore comfort and safety to your home.

No matter the species, the best defense is prevention. Here are simple ways to reduce your risk:
Seal cracks and gaps around doors, windows, and plumbing
Keep food stored in airtight containers

German cockroaches prefer warm, humid spaces with easy access to food. That’s why they’re commonly found around stoves, dishwashers, and refrigerators. Even small crumbs or grease can keep them thriving.Which cockroach is more common in homes?
German cockroaches are the most common household cockroaches. American cockroaches are usually found outdoors but can invade homes when looking for food, water, or shelter.Do cockroaches only infest dirty homes?

The fastest and most reliable way is professional pest control. Store-bought sprays may kill a few roaches, but they won’t stop the breeding cycle. A trained technician can identify the species and use targeted treatments that eliminate the infestation at the source.
