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 1: Fill a glass halfway with water.
✅ 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.
