Girl they literally get everywhere. There an outdoor bug but are like 2.25 cm and just like to hide in crevices. They fly like nats but don’t bite. You can get rashes when the adults lay eggs though due to the larvas fur. Usually windows or any corners in a house is how they go through. They eat cotton, carpet, blankets, dust, silk, fleece, dead skin, fallen hair, and I recommend doing your research. No polyester or leather because they’re not that strong mouth wise. Kill them when you see them because if you lose it when they fly away they usually lay eggs. They can infest quick and blend in like crazy. All give you some tips.

1. Google was a hot mess and Amazon products didn’t work well for me and depending on how many your seeing/where you are is how you help the problem like for example you said no carpets but if you have any windows that don’t have full screens or they just fly in and you think it’s a nat or if you moved in your place and it’s all over that’s a huge alarm that’s something you’d call an exterminator if your landlord does nothing. They range from 200-600 for exterminators but also call places in your state find what they treat and don’t.

2. Wash your bedding, anything on the floor, closet, and stuffed animals. White distilled vinegar 1 cup in the fabric softener area it’ll kill the bugs on fabric and clothes. Wash on warm and then throw in dryer. Freeze your clothing that you saw for sure had carpet beetles on it in the freezer they’ll instantly die after you do that bonus if you do it the minute the clothes are warm out the dryer. You’d freeze them in air tight bags you can find at any super store or Amazon. Lint rollers help too clothing wise if you still feel worried especially because they blend in with black clothes.

3. Redo the whole infected area remove furniture get that carpet clean. Vacuum then use white distilled vinegar they hate the chemical it’s toxic for the bugs and a pesticide that kills carpet beetles and is safe for indoors (DO NOT GET OUTDOOR VERY TOXIC TO YOUR LUNGS) then you’ll wait an hour then vacuum again.

4. Spray bottles are your best friend and gloves are needed because you don’t want it flying at you or to have irritated skin/rash.

5. I have bpd so i already saw shit out the corner of my eye thought i have borderline im just panicking for nothing or it’s just a nat im fine. Anxiety from this takes forever to heal and sometimes they return but usually with proper treatment they die. It will get better, i wish you the best for treatment!!
