Cockroach Basics: Understanding Their Presence

Signs of a Cockroach Infestation
Knowing the signs of a cockroach infestation is key to managing pests. Spotting these signs early helps prevent bigger problems. Look out for these common signs:
Common Infestation Indicators
- Droppings: You might find cockroach droppings that look like tiny pepper specks. A lot of feces means you have an infestation.
- Foul odors: A musty smell can come from roaches. This smell gets stronger as the infestation grows.
- Shed skins: Roaches shed their skin five to eight times. Look for these in their favorite spots.
- Smear marks: Find brown, irregular-shaped smear marks in damp areas. These are common on horizontal surfaces.
- Egg capsules: Roaches lay eggs in capsules, with up to 30 nymphs inside. Finding these means you have a big problem.
- Daytime activity: Seeing cockroaches during the day means you have a big infestation. They usually come out at night.
Tracking Down Hiding Spots
Cockroaches like dark, damp places in your home. Finding where they hide is important for controlling them. Common spots include:
- Under sinks

Seeing one roach means many more are around. Because they breed fast, a single female can have lots of babies. It’s important to call pest control experts as soon as you see any signs of cockroaches.
