If your house has a sunny south or west wall, you may see it covered in lady beetles over the next few weeks.
These are multicolored Asian lady beetles. In October and November they look for somewhere to spend the winter, and a warm wall with a gap in the siding or a torn window screen is exactly that.
Spraying the ones you see doesn't stop the next wave. Sealing cracks and fixing screens does. That's Clemson Extension's advice too, and it's how we handle it.
One more thing: don't crush them indoors. They can leave a yellow stain and a smell. A vacuum works better.
