Cockroaches

There are more than 4,000 species of cockroaches worldwide. Most live outdoors and play a role in breaking down decaying organic matter. However, a small number of species live close to people and are considered serious household pests due to the health and sanitation issues they create.

Cockroaches are highly adaptable insects that thrive in environments where food, moisture, and shelter are readily available. Once they establish themselves indoors, populations can grow quickly and become difficult to control without professional help.

How to Identify Cockroaches

Cockroaches vary in size and color depending on the species, but they share several common traits.

• Flat, oval-shaped bodies.

• Six legs built for fast movement.

• Long antennae that are as long as, or longer than, their bodies.

• Some species have wings, though most prefer running over flying.

• Primarily nocturnal, hiding during the day and becoming active at night.

Because they are most active after dark, early infestations often go unnoticed until signs become more obvious.

Are Cockroaches Dangerous?

Cockroaches are considered a health risk in both homes and businesses.

They can spread bacteria such as salmonella, which may cause symptoms like fever, vomiting, and diarrhea. Their droppings, shed skins, and saliva can also trigger allergies and asthma, particularly in children and individuals with respiratory sensitivities.

Beyond health concerns, cockroaches contaminate food and surfaces and may damage fabrics, upholstery, and stored items as they forage.

Why Cockroaches Invade Homes and Businesses

Cockroaches are scavengers and are drawn to properties that provide easy access to food and moisture.

Common attractants include:

• Trash and compost areas.

• Pet food and feeding stations.

• Outdoor eating spaces.

• Standing water or plumbing leaks.

They often enter structures through small gaps in foundations, exterior walls, and utility openings. Cockroaches may also be accidentally brought inside through deliveries, packages, used furniture, or appliances.

Where Cockroaches Are Commonly Found

Cockroaches prefer warm, damp environments and can live both indoors and outdoors.

Outside, they are often found:

• In mulch and flower beds.

• Under woodpiles and debris.

• Around trash cans.

• In sewers and drainage areas.

Inside, they tend to hide near food and moisture sources, including:

• Kitchens and pantries.

• Bathrooms.

• Basements and crawl spaces.

• Laundry rooms and utility areas.

When Cockroach Problems Require Professional Help

Seeing cockroaches during the daytime, finding repeated signs of activity, or noticing ongoing issues despite basic cleaning efforts often indicates a larger infestation. Because cockroaches reproduce quickly and hide in hard-to-reach areas, professional treatment is often needed to fully address the problem.
