A lot of people scrub their bathrooms constantly yet still wonder how cockroaches manage to show up — especially inside the shower. The truth is simple: bathrooms are warm, damp, and full of pipes… exactly what roaches love. And your shower drain? It’s basically a tiny doorway they can squeeze through.
But here’s the part most homeowners don’t know:
👉 A regular party balloon can stop them from crawling up through the plumbing.
It sounds strange, but it works — and costs almost nothing.
Roaches travel through pipe systems and can slip through incredibly small gaps. A balloon acts like a flexible seal that tightens the space while still allowing water to pass.
How to do it:
-
Remove your shower drain cover.
-
Cut the ends off a balloon to make a stretchy tube.
-
Slide it around the drain cover so it fits tightly.
-
Reinstall the drain cover — the balloon now creates a narrow, protective channel.
This trick works even better when paired with good habits:
• Keep the bathroom as dry as possible
• Wipe down surfaces after showering
• Clean around the drain to reduce humidity
• Seal small cracks around tiles or pipes
With basic upkeep + the balloon barrier, you can seriously reduce roaches and keep your shower fresher and pest-free.
