I also had bedbugs in bed that bit the skin on my head, which turned red because of this and there was severe itching. I didn’t know how to stop this itching, but my grandmother suggested that I try CBD on this site https://blessedcbd.co.uk/cbd-cream/. After using this CBD, the itching stopped and the skin on my head was restored. And we threw out the bedbugs along with the mattress to exclude a relapse. If you also have redness or itching, you can study this remedy and then try it.
