Bathrooms can be an unexpected entry point for pests, especially when warm, damp conditions make plumbing an inviting pathway. Shower drains, in particular, provide moisture and shelter, which is why insects sometimes appear even in well-cleaned homes. Instead of relying only on chemicals, many people look for practical, low-effort solutions that help reduce access points before pests become a recurring problem.
One straightforward approach focuses on limiting how easily insects move through the drain itself. Plumbing systems connect to wider networks, and small openings are often enough for pests to travel unnoticed. A simple household item—a party balloon—can help narrow that access. Start by lifting the shower drain cover. Take a standard balloon, cut off both ends, and turn it into a stretchy band. Fit this band snugly around the drain cover so it creates a tighter seal when replaced.
When the cover is set back in place, the balloon acts as a flexible barrier. Water can still flow normally, but the opening becomes far less accessible to crawling insects. This method works best as a preventive step rather than a standalone fix, helping reduce new intrusions rather than addressing an existing infestation.
For better results, pair this trick with basic bathroom upkeep. Keep surfaces dry, clean drain areas regularly, and check for small cracks around pipes or flooring that could serve as alternate entry points. Sealing gaps and reducing moisture makes the space far less appealing to pests. With consistent maintenance and a few clever adjustments, it’s possible to keep the bathroom cleaner, drier, and far less inviting to unwanted visitors.
