I live in Ottawa, Canada and noticed that in the last 3 weeks several
ladybugs inside my house around the windows. I'm trying to find out
how they get in. I checked all around the windows and there doesn't
seem to be any openings for them to get into. Any ideas on how
ladybugs usually get into a house ?
Thanks much.

I doubt that they got in recently. I suspect that they have been hibernating
inside without your permission or knowledge.
