Unpleasant odors rise from dried-out or dirty pipes
Insects (like flies, ants, or even cockroaches) enter through the drains
Humidity builds, causing mold or mildew
Siphons (the water traps that block odors) evaporate, removing the barrier between your kitchen and sewer gases
The result? You return home to find your kitchen filled with musty smells, stale air, or even pests — not exactly the relaxing welcome you imagined.
The Upside-Down Glass Trick: How It Works
This now-viral trick is brilliantly simple. Before you leave, do the following:
Thoroughly clean your sink and drain.
Place a sheet of paper towel or absorbent kitchen paper over the drain opening.
Place a glass (or sturdy plastic cup) upside down on top of the paper so that it fully covers the drain.
This creates a physical barrier that helps:
Trap odors
Prevent insects from crawling up into your kitchen
Reduce air and moisture circulation
Protect your kitchen from post-vacation surprises
It’s a low-tech solution with high-impact results.
