Cleanliness and Roach Infestations (What Causes Roaches In A Clean House?)

You might think that keeping your house spotless would prevent roach infestations, but that’s a misconception. Even the cleanest homes can suffer from roach problems.

Roaches are attracted to human food, pet waste, pet food, water, and shelter, which every home provides. While maintaining cleanliness can help reduce the likelihood of an infestation, it’s not guaranteed, especially if you live in an apartment with neighbors with roach issues.

  • Food: Make sure not to leave food out and store it properly in sealed containers. Removing their food sources will reduce the chances of attracting roaches. Because roaches can climb walls they can get in your cabinets, so make sure everything is sealed.
  • Water: Check for leaks or standing water in and around your home, as roaches need water to survive. Dry out all of your sinks each night.
  • Shelter: Roaches love dark and warm spaces, so do your best to seal cracks and prevent access to these potential hiding spots.

Roaches Only in Dirty Environments

Another misconception is that roaches are only found in dirty environments. The truth is cockroaches can be found almost anywhere, including the most pristine homes. 

Since roaches can travel on clothes, you may unknowingly bring in a hitchhiker.

They are highly adaptable creatures and have survived in various conditions for millions of years. It’s essential to be vigilant and take preventative measures regardless of your home’s cleanliness.

  • Please Inspect all Packages: I recently opened an Amazon box with a roach in the bottom of it. You only need one female carrying an egg casing to start the infestation.

  • Regular Inspections: Inspecting your home for any signs of roach activity can help prevent infestations from becoming a significant issue. Learn more about “what does roach poop look like” to help you with your inspections.

  • Professional help: If you notice a persistent problem with roaches, it might be time to call professionals to handle the issue. 

Since many cockroaches have adapted glucose aversions, some baits no longer work for them. So it’s better to call in professionals instead of buying bait online. Read or listen to the full story on “cockroaches adapting to pest control” here

Remember, having a clean home doesn’t guarantee a roach-free environment. Make sure to take proper preventative measures and remain vigilant to maintain a roach-free home!

Excess Moisture and Humidity

Keep your home well-ventilated, dry, and use a dehumidifier to remove extra moisture in the air. Furthermore, check for leaky pipes or dampness near sinks, bathtubs, and appliances. Roaches love water, so excess humidity in your home could invite them in.

One of Your Neighbors Has An Infestation

Unfortunately, if you live in an apartment building or complex, chances are that your neighbor’s roach problem can become yours. Roaches will travel from one unit to another for food and water, so check around your doors and windows for any potential entryways.

If you believe your building has a roach problem, put out some sticky traps so you can see where they are traveling. Then call in a pest control professional to help with baiting.

Cracks and Wall Openings

Roaches can enter your home through miniscule cracks and openings in walls and floors. Seal all gaps and crevices, even around doors and windows, to keep these unwanted guests out.

Unsealed Food Sources

While your house may be clean, it’s essential to securely store all food items, including dry goods and pet food, to avoid luring roaches. Use airtight containers, and never leave food out in the open.

Drain Traps That Dry Out

A dry drain trap allows sewer roaches to enter your home through the drainpipe. Make it a habit to run water regularly in all drains to ensure that the traps stay filled.

Pet Food That’s Left Out

Pet food, if left out, can also attract roaches. Feed your pets at specific times and promptly remove any uneaten food. Then, Store pet food in sealed containers to keep cockroaches away.

Cat Litter

Roaches love cat litter boxes because they feast on cat poop. Regularly clean and maintain litter boxes, and store extra litter in airtight containers. Check out our complete guide on “What do cockroaches eat?”


Clutter can act as a hiding space for roaches. Keep your living areas organized, and regularly declutter to minimize potential hiding spots for these pests.
