Attack of the Tiny Ladybugs

I didn't even get a chance to get closer.

A few nights back, I noticed a cute, little ladybug on my paper towel dispenser. So, naturally, I grabbed my camera. Before I could zoom in on it to get a closer shot, I heard a distinct "crunch" as I leaned forward. I looked down in horror to find a dozen dead ladybugs, rolled on their backs. After screaming "ew" about a thousand times and frantically washing my foot, I tried to figure out where they came from. Just then, I noticed about 50 more ladybugs sprawled out all over my floor, crawling their way from my front door to the kitchen. A couple were even flying around! It was like attack of the tiny ladybugs! I almost completely lost it.

After calming down and doing research online, I realized that

1. There was nothing I could do about it.
2. They don't eat furniture/curtains/etc.
3. They leave yellow trails.
4. There was probably a hive nearby.

After reading #4 and getting rid of all the ones on my floor, I opened my front door to find a hundred dead ladybugs near my doormat. I can only imagine what the gardeners thought when they cleaned it up the next day.
