Carpet beetle ID & management (found on couch in central Oregon)
Looking to confirm ID and get pest management tips.
First two photos are the larvae I think are carpet beetles that I found on my living room couch. Metric ruler shows mm marks.
3rd photo is either a different lifecycle stage or a different bug entirely.
Last two photos are adult beetles found in my living room, though not on the couch with the larvae. Both the brown one in the 4th photo and the darker one with spots in the last photo are just over 2 mm long. Unknown if either of these adults are related to the larvae but included as it seems possible.
TLDR I currently use:
Robot vacuum hits all floors 2x daily. I deep vacuum every 1-2 weeks.
Diatomaceous earth where I don't vacuum
Ortho Home Defense spray near entrance, windows and baseboards
Sticky traps under furniture and near entrance
Vacuum couch cushions and interior fabric about quarterly
Steam cleaner (Dupray Neat) on couch and carpets about 2x per year
Rarely used textiles are stored in sealed bins or bags
Soft, dim lighting at night (I'm a night owl)
Anything else I should be doing? Anyone have a preferred spray product that's worked well for them, or a type of bug trap?
For sprays in particular, are there any that work well applied to a fabric rather than hard surface? The Ortho is intended for hard surfaces, and I'd like something I can spray on the fabric inside and underneath my couch, and on the carpet underneath my furniture and along baseboards.

Full story:
I noticed some larvae on my couch that I think are carpet beetles. Went a little ballistic and thoroughly vacuumed and steamed both couches inside and out and all the carpet in my apartment. Also got a robot vacuum to help keep up with frequent floor vacuuming as I definitely wasn't doing it often enough, which also helps force me to pick up any clutter so it can clean better. I bought the couch set used about three years ago from a really clean house with vinyl floors. The couch material is white microfiber suede that I thought was synthetic, so I'm guessing it either has some natural fibers or the larvae are just eating dust and detritus I haven't vacuumed well enough. The light color makes it super easy to spot dirt and bugs, so I think I've kept it cleaner than if I had a dark couch.
I have fairly active pest management as I'm in an old rental with terrible insulation and the weatherstripping is long rotted away. I put sticky traps under furniture and near doors and windows, and spray Ortho Home Defense around the inside and outside around the windows, door frames, along baseboards and the walls behind furniture. I sprinkle diatomaceous earth along baseboards, under any furniture and appliances I don't clean often, and in the closets. In the summer I get a bit inundated with elm seed bugs and brown stink bugs that come in from the windows, which is what led to the regimen I now use. Since starting that about three years ago and resetting everything once or twice per year, the bug issues have reduced significantly, though these larvae are new to me and I've never seen them in the sticky traps, or any small beetles that could be the adult version. Sticky traps catch plenty of spiders, moths, weevils and earwigs, mostly near my front door.
For deep spring cleaning and bug reduction, I washed all textiles, and stored anything I don't use often in airtight bins or vacuum sealed bags. I went through my pantry and tossed anything old, but I didn't notice any bugs in the food. I did find a few dead larvae in my bedroom closet, so I made sure to thoroughly vacuum the shelves and replaced the soft storage cubes I was using with clear airtight sealed containers after thoroughly cleaning anything I'm storing. I usually hang winter coats in the closet year round but decided to wash and vacuum seal them for this summer. I also sealed up any really nice clothes like my wool suit after washing. Anything textile that couldn't be washed I bagged up and stuffed in the freezer for a few weeks, then put in sealed storage.
After all that, the biggest concentration was still inside the couch, and found maybe 20 larvae total. There's no way I'd notice them on brown rental carpet, but I'm assuming they live there too. I've ensured all carpet in the apartment is either hit twice daily by the robot (it fits under the couch) or has diatomaceous earth on it. I sprayed Ortho on the wood frame inside the couch and in some crevices I thought they might hide in, let that dry then sprinkled diatomaceous earth in all the crevices. I feel like that's probably the best I can do. I'm sure there's plenty of bugs under the carpet and behind baseboards, but there's nothing I can do about those except ensure they have to crawl through poison to come out to my living space.
Last note that was a recent change is I stopped using the built-in overhead lights after dark. I'm often up pretty late, much later than my neighbors. I think the bright lights were attracting a ton of bugs to my windows at night, so I got a little smarter and made sure every room has alternative lighting that isn't nearly so bright, and isn't directed towards any windows. I'm hoping that helps to not bring so many bugs in. Blackout curtains might help, but I'm not the best with daily routines so I got rid of the ones I used to have because I would live in the dark more than half the time. I use the cheap rental blinds at night and have sheer curtains that cover all the windows. Those seem to help prevent flying bugs from leaving the window area, and instead get funneled down into the death zone of Ortho and diatomaceous earth. I vacuum the windowsills at least weekly in the summer when the bugs are the worst.
