After going outside it appears there are, and this isn’t an actual head count just a best guess, hundreds of thousands of lady bugs swarming around our apartment building alone. Due to other friends reporting the same in their area I’m calling it a plague.
This happened about 15 years ago at my junior high school…
The inside walls of most classrooms were covered and the floors becames a gross crunchy sticky mess.
Don’t let them inside.
We tried our best but ended up needing to vacuum a ton of them up. It seems though, that a lot of them died overnight in the cold.
