3. 🪳 Cockroaches
Why they come:
Roaches love moisture and darkness — making bathroom drains an ideal habitat. They often crawl up from sewer pipes or plumbing voids.
How to stop them:
Pour boiling water, vinegar, or baking soda + vinegar mix down the drain weekly.
Seal gaps between pipes and wall/floor areas with caulk.
Use drain stoppers overnight or when you’re away.
