Tons of these in our place before we moved in: clothes moths? [Vacaville, CA]

Sorry for poor quality, just have my phone right now with terrible macro. We found 30-40 of these moths flitting around the house before any of our stuff was moved in (we're renting). iNaturalist suggested case-bearing clothes moths (Tinea pellionella) as the top match. Would you guys agree? How should we protect our clothes? I have a cat, so I think mothballs are not possible. We bought pheromone traps but aren't catching any. I also haven't seen any larvae, so maybe the species ID is not right.

Edit: behaviorally, they were flitting around irregularly, seem most active after late afternoon. They land frequently on the walls. When landing, they sometimes wiggle antennae. They are easy to smash with a fly swatter and even midair. Unclear where they're coming from but we're wondering if they're crawling out of wall cracks, going to caulk up cracks to see if that helps keep them out

Have you checked the cabinets and pantry in the kitchen? These could be leftovers from previous owners' infested packages, or a new generation of pantry moths. Just a guess.
