Attracted to warm, damp spaces, cockroaches frequently use bathroom shower drains as entry points into clean homes.
A simple DIY hack using a cut party balloon fitted tightly around the drain cover edge can narrow gaps and block incoming pests.
Homeowners using this method must check it regularly to ensure the rubber ring does not collect hair, trap debris, or slow down water drainage.
For complete control, combining this quick drain barrier with moisture reduction, regular pipe cleaning, and sealing wall cracks provides the best protection.
