At first, the idea seemed almost too easy to ignore: stretch a balloon over the shower drain when the bathroom was not being used, and supposedly insects would stay outside. The trick became popular through viral videos promising a quick way to keep pests away. However, covering one drain does not always address the real problem. Bathrooms naturally provide moisture, warmth, darkness, and hidden spaces that insects may find attractive, while cracks, gaps around pipes, doors, and walls can offer other ways inside.
One of the most important steps is reducing moisture. Leaking faucets, damp areas under sinks, standing water, condensation, and plumbing leaks can make a bathroom appealing to insects. Keeping the room dry, repairing leaks, cleaning regularly, and improving ventilation can make the environment less attractive. As the article explains, “Moisture is one of the biggest factors to address.”
Homeowners should also inspect areas around plumbing instead of focusing only on the drain. Small openings around pipes, damaged caulking, cracks near fixtures, gaps beneath cabinets, and spaces along baseboards can become entry points. Doors and windows should also be checked for damaged seals. Properly sealing suitable gaps can help prevent insects from finding their way inside.
The drain itself still needs regular maintenance. Cleaning away buildup and making sure plumbing traps work properly can help keep the bathroom sanitary. However, a balloon is not a replacement for proper plumbing care. If insects continue appearing, the source could be hidden elsewhere in the home, possibly connected to moisture, damaged plumbing, or an established infestation.
The main lesson is that viral household hacks may provide a temporary solution, but lasting pest prevention requires finding the source. A balloon cannot repair leaks, reduce humidity, or seal every possible entry point. Keeping the bathroom dry, maintaining the plumbing, checking for gaps, and dealing with the underlying problem is usually far more effective. “The most effective solution is rarely the cleverest-looking hack.”
