Identify this bug (which looks like a cross between a beetle and a bed bug)
That is a weevil. Coleoptera, Curculionidae. Weevils have distinctive snouts, and elbowed antennae. They can be crop pests, and eat seeds, but do not spread diseases to humans. I suspect these have just found their way into your home by mistake. https://bugguide.net/node/view/1126677
