I've been finding these small ladybug looking insects can someone help me find out what it is?

The size of the bugs is about the diameter of a candle wick. I have found them on the walls of the living room and my bedroom. They look similar to the varied carpet beetle or a ladybug. The ones I'm finding are brown, black, white spotted. I don't think it's a carpet beetle because we don't have any carpeting or rugs and our window coverings are vinyl blinds (no curtains.) I have not found any actually on my bed. What could they be and what can I do about them? Please answer only if you have some idea of what they could be. Thanks you.
