3. Deters Pests

A dry drain is an open invitation for insects, rodents, or even snakes to crawl up. Keeping the P-trap moist helps block their entry.

How to Do It Right

✅ Step 2: Place a dry piece of paper in the sink.
✅ Step 3: Turn the glass upside-down over the paper.
✅ Step 4: Repeat for every sink & shower drain in the house.

Bonus Tip:

• For extra protection, pour ½ cup of vinegar + 1 tbsp baking soda down drains before leaving to prevent clogs.

When This Trick Is a Lifesaver

• Long trips (2+ weeks)

What Happens If You Skip It?
