Keeping cockroaches out of the bathroom can be challenging, especially when they enter through the shower drain. These pests are drawn to warm, damp environments, making bathroom pipes an appealing place to hide. Even with regular cleaning, they may still find ways inside, which is why many homeowners look for simple, effective methods to block their entry. One surprisingly helpful trick involves nothing more than a regular party balloon.
Cockroaches often move through plumbing systems, taking advantage of small openings. Because shower drains remain moist, they become a common entry point. The balloon method works by narrowing the drain opening, making it more difficult for insects to crawl through. To try it, start by removing the shower drain cover. Cut both ends off a standard balloon to create a flexible tube, then slide it around the drain cover so it forms a snug fit.
When the cover is placed back on the drain, the balloon creates a smaller passage that still allows water to flow but helps block most pests from squeezing through. While this method can be effective, it works best alongside general prevention habits. Keeping the bathroom dry, wiping surfaces regularly, and cleaning drain areas can reduce the moisture that attracts cockroaches in the first place.
It’s also helpful to inspect the bathroom for cracks or gaps around pipes and seal them promptly to keep insects from entering through hidden spaces. With these simple steps — combined with the balloon technique — you can make it easier to maintain a cleaner, more comfortable bathroom environment. Regular upkeep can greatly reduce unwanted visitors and keep your shower area fresh and pest-free.
