Why Do Roaches Use Drains?

Cockroaches are drawn to warm, dark, and moist environments & drains offer all of those conditions. Also, plumbing systems can serve as convenient passageways, especially in apartment buildings and older homes where pipe gaps are common.

Key reasons roaches come through drains…

• Access to water

• Shelter and hiding places

• Easy entry points from sewers or neighboring units

Which Drains Are Most at Risk?

While any drain could potentially be used, cockroaches are more likely to come up through…

• Kitchen sink drains (especially with food debris)

• Bathroom sink or shower drains

• Floor drains in laundry rooms or basements

Roaches can enter through both dry and active plumbing systems if not properly sealed or maintained.

What Types of Roaches Come Through Drains?

The American cockroach (also known as a water bug or palmetto bug) is the most likely species to crawl up through pipes. These roaches often live in sewers and can travel through plumbing lines into homes.

What If You Already See Roaches?

If you’ve spotted roaches coming from drains…

• Clean and seal the area immediately

• Use gel bait traps around the drain openings

• Consider calling a professional if the issue persists, especially if you live in a multi-unit building

Roaches can & do come up through drains, especially in homes with easy access to food and moisture. Fortunately, with the right preventative measures & a little routine maintenance, you can stop them from using your plumbing as a pathway into your home.
