Before leaving for vacation, many people remember to lock doors, unplug appliances, and turn off the water supply, but they often overlook the sink. Leaving drains uncovered while a home sits empty can lead to unpleasant odors, excess moisture, and even attract insects. Spending just a few extra minutes preparing your sinks can help keep your home fresher while you’re away.

One common reason for bad smells is that plumbing fixtures remain unused for several days. During that time, water inside the drain traps may evaporate, allowing **”sewer gases”** to enter the home. Damp drains may also become an easy entry point for small pests, including gnats, ants, and cockroaches, especially in warmer weather.

A simple way to help prevent these problems is to clean the sink before you leave. Pour hot white vinegar down the drain to remove buildup, let it sit for a few hours, and then flush it with warm water. For a fresher smell, rub a lemon wedge around the drain, dry the sink completely, cover the drain with a paper towel, and place an upside-down glass over it.

This extra barrier can help reduce odors and make it more difficult for insects to enter through the drain while the house is empty. Although it is not a perfect solution for every situation, it is an easy, inexpensive step that many homeowners find worthwhile.

Taking a little time to prepare your sinks before a trip can make a noticeable difference when you return. As the article explains, **”it isn’t a guaranteed solution in every situation,”** but this simple precaution can help you come home to a cleaner, fresher-smelling house with fewer unwanted surprises.
