7 Areas in Commercial Buildings Where Pests Commonly Hide

Last updated on October 5th, 2026 at 09:01 am

When people think about pest problems, they often imagine pests crawling across floors or appearing in plain sight.

But in commercial buildings, much of the activity can happen behind the scenes.

Pests naturally seek places where they can find food, moisture, shelter, and minimal disturbance. That means some of the most important areas to inspect are also the areas employees and customers rarely notice.

Here are seven areas businesses should pay attention to.

1. Storage Rooms

Storage rooms can provide plenty of hiding places, especially when boxes, supplies, and unused materials remain undisturbed for long periods.

Cardboard boxes and clutter can also make inspection more difficult.

What businesses can do: Keep storage areas organized, avoid excessive clutter, inspect incoming goods when appropriate, and regularly check areas behind and underneath stored materials.

2. Kitchens and Pantry Areas

Food preparation and employee pantry areas can attract cockroaches, ants, rodents, flies, and other pests.

Food crumbs, spills, improperly stored food, and moisture can provide the resources pests need.

What businesses can do: Clean spills promptly, store food properly, empty waste bins regularly, and clean underneath appliances and cabinets.

3. Drains and Moist Areas

Floor drains, sinks, leaking pipes, and other damp areas may provide pests with moisture.

Some insects may also breed or develop around drains containing accumulated organic material.

What businesses can do: Keep drains clean, address leaks, remove standing water, and investigate persistent moisture problems.

4. Ceilings and Roof Spaces

Pests are not limited to areas near the floor.

Rodents and other pests may move through ceiling voids, roof spaces, utility openings, and structural gaps.

Because these spaces are often hidden, pest activity may go unnoticed until employees hear noises or notice droppings and other signs.

What businesses can do: Inspect possible entry points and pay attention to unusual sounds, damaged materials, droppings, or other evidence of activity.

5. Utility and Maintenance Rooms

Electrical rooms, mechanical spaces, utility areas, and maintenance rooms usually receive less daily foot traffic.

These quieter environments can provide pests with relatively undisturbed shelter.

What businesses can do: Include these rooms during routine facility inspections and avoid allowing unused materials to accumulate.

6. Garbage and Waste Areas

Waste areas can become major pest attractants when garbage is not properly contained or removed regularly.

Food waste and other organic material can attract flies, cockroaches, rodents, and other pests.

What businesses can do: Use properly covered waste containers, maintain cleanliness around bins, remove waste regularly, and clean spills or residue.

7. Landscaping and Building Perimeters

Pest prevention should not stop at the building’s doors.

Vegetation, standing water, debris, drainage problems, and gaps around the exterior can create conditions that encourage pest activity near the property.

From there, pests may eventually find their way indoors.

What businesses can do: Maintain landscaping, remove standing water and unnecessary debris, and inspect the exterior for possible pest entry points.

Pest Prevention Starts With Knowing Where to Look

Pest activity is not always obvious. Regularly checking areas where pests are likely to find food, water, shelter, or entry can help businesses identify potential concerns earlier.

Combined with proper sanitation, building maintenance, monitoring, and professional pest management, these practices can help reduce pest risks around commercial properties.
