Mouse droppings found

So the other day I saw two mouse-like droppings behind the toilet when cleaning but kind of dismissed it. Now this evening, I opened the cabinet under the kitchen sink and found maybe a dozen droppings.

Super is coming tomorrow to assist with plugging holes behind the appliances and an exterminator is scheduled to come on Monday.

I have all of the food packaged up properly and the apartment is very clean. I am on the third floor of an elevator building. Kind of afraid to start tearing apart the apartment tonight and rather wait for tomorrow in the daylight.

Anyone have recent experiences and suggestions in the interim? Do I wait for the exterminator to come? Do I buy traps asap, if so which ones? Do I spray scents or other home remedies (fostering a cat not an option)?

Thanks so much all
