Before heading out on vacation, most people run through the same checklist: unplug appliances, lock doors, take out the trash, and shut off the water. But there’s one small spot that’s often overlooked—and it can cause unpleasant surprises when you return.
The sink.
When a home sits unused for days or weeks, especially in warm weather, plumbing systems don’t get the regular water flow that helps keep them sealed.
As water in the drain trap slowly evaporates, it can open a pathway for sewer gases to rise back into the house. At the same time, dark, damp pipes can become an easy entry point for insects.
The result? Musty odors, lingering smells, or even bugs waiting for you when you get home.
Fortunately, there’s a simple, no-cost trick that helps prevent all of that.
By placing a paper towel over the drain and setting an upside-down glass on top, you create a physical barrier that blocks sewer gases, moisture, and insects from coming up through the pipes. The paper towel helps seal the opening, while the weight of the glass keeps everything in place.
This method is often more reliable than standard sink stoppers, which can dry out, lose suction, or shift over time—especially during longer absences. The glass doesn’t rely on a perfect seal and won’t move easily once set.
To prep your sink properly before leaving:
Clean the sink thoroughly.
Pour hot white vinegar down the drain to help break down residue.
Let it sit for a few hours, then rinse with warm water.
Rub a lemon wedge around the drain for a fresh scent.
Dry the sink completely.
Place a paper towel over the drain and cover it with an upside-down glass.
It’s a small step that takes less than a minute—but it can make a noticeable difference. Coming home to a house that smells fresh and shows no signs of pests sets the tone for a calm, stress-free return.
So before you grab your suitcase, take one last look at the sink. That simple glass-and-paper trick might be the quiet hero of your vacation checklist.
