They try to crawl into the cracks in the walls this time of year to hide from winter. If they do get in, they come out when it's sunny and warm.

And if they don't?
Then they go away after it gets a little colder.
They freeze in the winter.
My folks in Toronto tell me it was super summery weather until last week, and now it's gotten cooler. So it's no surprise bugs are trying to escape the cold into indoors.
Tis fall, they are bums and want to hide in a warm spot for the winter. For us itβs a ton of stink bugs this year, last year was the lady bugs.
It's hard to tell on my phone from the pics, but those shells look orange, not red. Those might be Asian Lady Beetles and are an invasive pest. They try to crawl into homes about this time of year to overwinter.
They definitely look more yellow-orange than red. Can you tell if it's that beetle from these?
Looking a bit online, it seems that the Asian Lady Beetle has a white spot on the head between the head and the body. These all have that. Also many of them have an obvious "M" shape there.
From a brief reading they only cause nuisance and I don't see recommendation to kill them.
I'm not 100% on ladybug lookalikes but yeah, that for sure looks like the Asian lady beetle to me. They're not the most harmful thing and were intentionally released in the U.S. to control aphids. I can't advise more sadly.
I'll put away the vacuum.
the only thing i find about them that IS a good reason to kill them is that they are (and have since the 70s when they were introduced into North America) detrimental to the the native population of ladybugs (the red ones) and also, these guys can bite and there's also a possibility you might have a allergic reaction to the bite. I have handled a bunch of these guys and never been bitten, but my anecdotical evidence is not something to go off of.
It's not an invasion. They've always been here. You just noticed.
