How to Stop Roaches From Coming Up The Drain?

Dealing with roaches coming up the drain can be a frustrating problem to tackle. However, with the right strategies and preventive measures, you can effectively prevent roaches from using your drains as access points into your home. This guide by Emma Ferguson provides a step-by-step approach to help you keep roaches out of your drains for good. You need to follow the below-mentioned steps to stop cockroaches from coming up the drain.

Maintain Clean Drains Regularly

Cleaning and maintaining your drains is crucial for preventing roaches from using them as entry points. Follow these steps to ensure clean drains:

  1. Use a drain cleaner or a mixture of vinegar and baking soda to flush the drains. This helps eliminate any residue or food particles that may attract roaches.
  2. Remove hair, debris, and other potential blockages using a drain snake or a wire hanger.

Install Drain Screens or Covers

Preventing roaches from entering your drains can be achieved by installing drain screens or covers:

  1. Purchase drain screens or covers that fit the size of your drains.
  2. Install them securely over all drain openings in your home, including sinks, bathtubs, and floor drains. These screens or covers will act as physical barriers, preventing roaches from entering your home through the drains.

Eliminate Attractants

Roaches are attracted to water, food, and damp environments. By eliminating these attractants, you can discourage them from coming up the drain:

  1. Repair any leaks or dripping faucets to minimize excess moisture.
  2. Clean up spills, crumbs, and food debris promptly, especially in the kitchen and bathroom areas.
  3. Store food in airtight containers and dispose of garbage regularly.

Seal Entry Points

Roaches can find their way into your home through tiny cracks and crevices around your plumbing system. Seal these entry points to prevent their entry:

  1. Inspect the areas around your drains, pipes, and plumbing fixtures for any gaps or openings.
  2. Use silicone caulk or weatherstripping to seal these gaps, ensuring a tight seal that roaches cannot penetrate.

Use Roach Control Measures

In addition to preventive measures, it may be necessary to implement roach control measures to eradicate any existing roach population:

  1. Apply roach baits or gel in areas near drains to attract and eliminate roaches.
  2. Use insecticide sprays or dusts as a last resort, following the manufacturer’s instructions carefully. Focus on treating areas around drains and plumbing access points.

Regular Maintenance and Inspection

Maintaining a roach-free environment requires ongoing effort and vigilance:

  1. Conduct regular inspections of your drains and plumbing system to check for any signs of roach activity or potential entry points.
  2. Continue to practice good sanitation habits, such as cleaning drains, sealing entry points, and eliminating attractants.


Preventing roaches from coming up the drain requires a multi-faceted approach that includes maintaining clean drains, installing drain screens, eliminating attractants, sealing entry points, and implementing roach control measures when necessary. By following these steps and staying proactive, you can effectively keep roaches out of your drains and enjoy a roach-free home.
