They could be the invasive Asian Lady Beetle, which is NOT our beloved lady bug! They’re nasty.
“Even though Asian lady beetles look like ladybugs, they sure don’t act like them! First and foremost, ladybugs don’t sneak into your home the way Asian lady beetles do. While ladybugs overwinter in sheltered sites outdoors, Asian lady beetles often enter homes.
If you notice the bugs congregating in or around your home in fall or winter, they’re probably Asian lady beetles. So, if you think you need ladybug pest control, you actually need Asian lady beetle pest control services.” https://plunketts.net/blog/ladybugs-vs-asian-lady-beetles
