Before leaving for vacation, most people remember to lock doors and unplug electronics, but many overlook their sink drains. When a home sits empty for days or weeks, especially in warm weather, the water inside drain traps can evaporate, allowing unpleasant sewer odors to enter. The damp pipes may also attract insects looking for moisture, making your return home less pleasant.

A quick and inexpensive solution is surprisingly effective. As the original article explains, **“A surprisingly effective method is covering the sink drain with a paper towel and placing an upside-down glass over it.”** This simple barrier helps block odors, sewer gases, and insects from coming through the pipes, while remaining more secure than some drain stoppers that can loosen over time.

Before sealing the drain, clean the sink thoroughly by removing food scraps, soap residue, and buildup. Pour hot white vinegar down the drain to help dissolve deposits and reduce lingering smells. After letting it sit for a few hours, rinse with warm water and dry the sink completely to prevent excess moisture.

For an extra fresh scent, **“rubbing a lemon wedge around the drain area can leave a pleasant smell before you leave.”** Once the sink is clean and dry, place a paper towel over the drain opening and cover it with an upside-down glass. The setup takes only a minute but provides an extra layer of protection while you’re away.

This simple habit can make a big difference when you return. Instead of being greeted by stale odors or unwanted pests, you’ll likely come back to a cleaner, fresher home. Spending just a few minutes preparing your sink before leaving can help keep your house comfortable and problem-free throughout your vacation.
