Signs of an American Cockroach Infestation in Your Southern California Home and How to Get Rid of Them
If you’ve spotted a large, reddish-brown cockroach scurrying across your floor or flying out of your drain, chances are you’ve encountered an American cockroach—one of the most unwelcome pests in homes across Greater Los Angeles and Southern California.
Also known as “palmetto bugs” or “water bugs,” these pests are among the largest cockroach species in the U.S. and can be incredibly difficult to eliminate without professional help. Here’s what you need to know about the signs of an infestation, what attracts them, and the most effective ways to get rid of them for good.
What Are American Cockroaches?
American cockroaches are about 1.5 to 2 inches long, reddish-brown with a yellowish figure-eight pattern behind their heads. They are fast runners, capable of flying short distances, and often live in warm, damp environments like sewers, basements, and crawl spaces. Once inside your home, they can multiply quickly and contaminate food and surfaces.
Signs You May Have an American Cockroach Infestation
Not sure if you have a roach problem? Look for these common warning signs:
1. Frequent Sightings
Seeing roaches during the day is a strong sign of a larger infestation, as they’re typically nocturnal and avoid light.
2. Droppings
American cockroach droppings resemble small black pepper grains or specks and are often found in corners, under sinks, or near baseboards.
3. Egg Capsules (Oothecae)
These are small, reddish-brown capsule-shaped objects that can hold dozens of roach eggs. You might find them behind appliances or in dark cabinets.
4. Musty Odor
A strong, oily, musty smell often indicates a large population of cockroaches is nearby. The odor comes from the pheromones they release.
5. Shed Skins
Roaches shed their skins as they grow. Finding these exoskeletons in hidden areas is another sign of infestation.
What Attracts American Cockroaches to Homes?
American cockroaches thrive in hot, humid conditions—which makes Southern California homes especially vulnerable, especially during the warmer summer months. Here’s what draws them in:
Moisture – Leaky pipes, damp basements, and standing water
Food Sources – Crumbs, pet food, grease, and unsealed pantry items
Clutter & Trash – Cardboard boxes, piles of paper, and uncovered garbage
Open Access Points – Gaps in windows, doors, vents, or utility lines
Once they gain access, they can spread bacteria and allergens throughout your home.
