What Causes Roaches in a Clean House?

Cockroaches, specifically German cockroaches, are often associated with dirty and unsanitary homes, which can be true to an extent. But you’re an excellent housekeeper and know good and well your home is clean. So why are you suddenly seeing roaches in your house?


You may be relieved to know that the issue probably stems from factors that don’t involve your cleaning abilities. Learn what causes roaches in a clean house and what attracts roaches to even the tidiest of homes.

The Region of the United States in Which You Live

First, consider where you live. For example, if you call a state like Florida, Georgia or Alabama home, you’re bound to have roaches get into the house at some point. This is especially true if you live in an area with a lot of American cockroaches, sometimes referred to as palmetto bugs.

Does seeing a palmetto bug in your home one evening after there’s been a lot of traffic in and out of the side door mean you have an unsanitary home or a roach infestation? Not necessarily. It’s more likely one just snuck in an opening, such as under a window seal gap, screen door, etc.

Areas in Your Home That Need Repairing

When thinking about what causes roaches in a clean house, you probably first land on the areas that are within plain sight, such as kitchen counters, dining room floors and so forth. And it’s true that you do need to keep these places tidy and free of crumbs or food residue, as little daily messes such as those are part of what attracts roaches to a location.

But roaches are also looking for shelter and water. That means they’ll creep in through cracks in the exterior of your home, dryer vents and even gaps in between your wall and floor. Walk the perimeter of your house and seal these up to eliminate cockroach entry points. While you’re at it, repair any leaky spigots or sinks and unclog rain gutters to cut off water sources for the insects, including cockroaches.

Roach Entry Points and Attractants that Fade Into the Background

Repairs are one thing, but there are also areas of the home that we just don’t think about as being access points or attractants for roaches. And while they don’t necessarily need to be fixed, they do need to be addressed in order to help prevent a roach infestation. Some items that may blend into the background or be forgotten include:

  • The spaces between outside doors and floors
  • Window screens that aren’t flush or that have small tears
  • Air conditioner units that don’t fit properly in windows
  • Crumbs underneath toaster ovens, stoves or refrigerators
  • Pet food or water that’s left out at night
  • Trash cans that aren’t cleaned regularly (including bathroom trash cans)
