How to Identify Cockroaches
Cockroaches are oval, flat-bodied insects with long antennae and a glossy appearance ranging from light brown to dark reddish-brown or black. German cockroaches are small, light brown, and the most common indoor species, thriving in kitchens and bathrooms. American cockroaches are larger and reddish-brown, often found in basements and drains, while Oriental cockroaches are darker and prefer damp, cool areas. Spotting their droppings, which look like coffee grounds or black pepper, and a musty odor are telltale signs of which species has moved in.
Signs of an Cockroaches Problem
- Live roaches scattering when you turn on a light at night
- Droppings resembling coffee grounds or black specks
- A musty, oily odor in infested areas
- Egg cases (oothecae) tucked in cracks and corners
- Smear marks along walls and baseboards in damp areas
- Shed skins near hiding spots
Why Cockroaches Are a Problem
- Cockroaches spread bacteria like Salmonella and E. coli
- Their droppings and shed skins trigger allergies and asthma
- They contaminate food and food-prep surfaces
- Populations multiply extremely fast if left untreated
- They can carry pathogens across the home as they travel
Why DIY Often Falls Short
Cockroaches breed quickly and hide deep inside wall voids, appliances, and cabinetry where sprays can't reach. Many populations have also developed resistance to common over-the-counter insecticides, so retail foggers and sprays may scatter them into new areas without reducing the population. A single egg case can hatch dozens of new roaches, so unless treatment reaches the harborage points and disrupts the breeding cycle, the infestation rebounds.

Cockroaches FAQs
Does seeing one cockroach mean I have an infestation?
Often, yes. Roaches are nocturnal and hide well, so spotting one during the day usually means a larger population is nearby. It's worth inspecting and acting quickly.
Why don't store-bought roach sprays work?
Many roach populations resist common retail insecticides, and sprays don't reach the hidden areas where roaches breed. Professional baits and growth regulators target the colony more effectively.
Are cockroaches a health risk?
Yes. They spread bacteria, contaminate food, and their droppings and shed skins can trigger allergies and asthma, especially in children. A licensed pro can help eliminate them — call to get matched with one near you.
