I’m renting out part of my home to a couple but they frequently leave what I think is baking soda by my doorstop. Why would they do this?

3. Cleaning purposes: It is possible that your tenants are using the baking soda to clean the entryway. Baking soda is mildly abrasive and can be effective in cleaning up grime and dirt that gets tracked in from outside.
4. Superstitious or cultural practices: In some cultures, sprinkling baking soda or other substances by the doorstep is thought to ward off evil or bring good luck. This might be a practice the couple adheres to based on personal or cultural beliefs.
5. Pest control: Baking soda can be used as a natural pest deterrent. The tenants might be trying to keep ants or other insects from entering the property.
Approaching the Situation with Tact
Being considerate of your tenants’ privacy and comfort is important, but it is also your right as a homeowner to understand and manage what happens in your property. Here’s how you can address the situation respectfully:
1. Direct but polite communication: Consider asking your tenants in a casual and concerned manner. You might say something like, “I’ve noticed some baking soda by the door lately. Is everything okay? Is there anything you need?”
