Many people clean their bathrooms regularly yet still wonder how cockroaches manage to appear, especially inside the shower. These insects are naturally drawn to warm, moist environments, and bathroom drains create the ideal conditions. What most homeowners don’t realize is that a simple party balloon can serve as an effective barrier to stop bugs from crawling up through the plumbing. It may sound unusual, but this inexpensive trick has quickly become a popular solution for anyone wanting extra protection with minimal effort.
Cockroaches often travel through pipe systems and can squeeze through incredibly small openings, especially in damp drains. By turning a balloon into a flexible seal, you reduce the size of that entry point while still allowing water to pass.
The method is simple: remove your drain cover, cut the ends off a balloon to create a stretchy tube, and slide it tightly around the cover. Once reinstalled, it forms a slim protective channel.
Combined with good bathroom habits—keeping surfaces dry, reducing humidity, and sealing small gaps—you can significantly reduce unwanted pests and keep your shower fresher and more comfortable.
