I also have carpet beedles in my bed, mostly crawling on my legs and feet, they are also in my shoes. They are under my desk where I have my computer. Have had my house sprayed 4 times to no avail. They are driving me crazy.
I put flea and tick powder in and underside of couch, in baseboards. It seemed to kill off a lot of them. But there are more.
They are also in my car. I spray my legs with windex at night when I feel them. Also use peppermint oil on my legs. They don't like either.
They also crawl in my clothes.
No one else feels them when they come to visit. I feel like I am a host.
Sometimes I feel they are living on my legs. But I guess I could be wrong. Don't know. I also have bites.. red bumps on my chest arms and legs that don't seem to go away for a long time. Try sweeping the floor every day and you can see if it's the same every day.
Good luck to all of us
