It is quite common to find roaches in even the most clean and tidy homes. This is because roaches are resilient and can easily access your home, usually through small and inconspicuous cracks and crevices. Roaches can thrive even in unsanitary conditions and can survive for a long time without food or water. To fully understand why your clean home has roaches, it is important to examine the reasons why and the ways to prevent an infestation.

Signs of Roach Infestations

Stains, Saliva and Droppings

A common sign of roaches in your home is the presence of stains, saliva and droppings. Roaches will often leave behind small dark stains near their hiding spots. You may also spot trails of saliva near their entry points of the home. Droppings will be around the areas they have traveled and fed on.


Roaches will also leave a unique smell in your home. The smell is described as a musty and stale odor. This smell may become more pungent if there is a large number of roaches or they have been in your home for a long period of time.

Nocturnal Habits

Roaches typically become active at night and remain hidden during the day. You may be able to spot them when you turn on a light, as they will usually try to scurry away. They may also travel around kitchen counters and floors.

Reasons For Roach Infestations

Food and Water

Your home may contain sources of food and water that are attracting roaches. Roaches feed on a variety of foods, including crumbs, pet food, and grease. Small amounts of water from sinks and other sources can also provide them with the moisture they need to survive.

Entry Points

Roaches will usually enter homes through cracks, vents, and other small openings. These entry points make it much easier for roaches to access your home. They may also find their way in through grocery bags, boxes, and other items that have been brought into the house.

Favorable Conditions

Roaches will also look for warm and humid conditions in which to thrive. Areas like laundry rooms, bathrooms, and basements are all ideal breeding grounds for roaches. Cluttered and dark spaces also make it easier for roaches to hide and build nests.

Preventing Roach Infestations

Keep Your Home Clean

Regularly cleaning your home can help to reduce the chance of a roach infestation. Vacuum often, especially in areas where crumbs and other food particles may have spilled. Wipe down counters and surfaces with a disinfectant cleaner.

Seal Cracks and Entry Points

Inspect the outside of your home for any cracks or open entry points. Seal any of these with caulking or other appropriate materials. Make sure to also check for anything that may provide access to water, such as leaky pipes and faucets.
