How to Stop Cockroaches Coming Out of Drains

Ingredients / Supplies

Baking soda – 2 tablespoons

White vinegar – ½ cup

Boiling water – 2 cups

Optional: Boric acid powder – 1 teaspoon (for stronger, longer-term effect)

Method

Clean the Drain: Remove any visible debris from the drain and run hot water for a minute to loosen grime.

Apply Baking Soda: Pour 2 tablespoons of baking soda directly into the drain.

Add Vinegar: Pour ½ cup of white vinegar into the drain. It will fizz and bubble—this reaction helps dislodge debris and kill germs.

Wait: Let the mixture sit for 10–15 minutes.

Flush with Boiling Water: Pour 2 cups of boiling water down the drain to wash away cockroaches, eggs, and residue.

Optional Extra Step: Sprinkle a teaspoon of boric acid powder into the drain to act as a longer-term deterrent.

Tips

Repeat this method once a week to keep drains cockroach-free.

Keep drains clean and avoid leaving food scraps near sinks.

Seal any cracks or gaps around pipes to prevent entry.

This simple combination of baking soda, vinegar, and boiling water is non-toxic, easy to use, and very effective at flushing out cockroaches from drains.
