Before leaving for vacation, many people remember to unplug appliances, secure valuables, and check the water supply, but often overlook their kitchen and bathroom sinks. When a home sits empty for several days, drain traps can dry out, potentially allowing unpleasant sewer odors to enter the house. Damp conditions and openings around plumbing may also contribute to pest problems, making a little preparation worthwhile before heading away.

One simple household trick is to place a paper towel over the sink drain and cover it with an upside-down glass. This creates a temporary cover that may help discourage odors and insects from coming through the drain, although it is not an airtight seal or a guaranteed solution. Before leaving, clean the sink, remove food residue, and make sure the drain is clear. If you use a drain stopper, check that it fits properly, and remember that keeping the plumbing trap filled with water is an important way to help block sewer gases.

A few minutes of preparation can help keep your home fresher while you are away. Avoid pouring hot vinegar into the drain as a supposed disinfectant, since it is not a reliable solution for preventing sewer gases or pests. Instead, focus on cleaning the sink, maintaining the drain trap, and addressing any existing plumbing problems before your trip. These small precautions can help reduce unpleasant surprises and make returning home after a relaxing vacation much more enjoyable.
