Then you tell yourself to shut up and get the vacuum.
We try our best to save the ones in the house before they starve, but we can only get to so many of them before they kick the bucket. This year seems worse than last year, and I know it will only get worse as the weather gets warmer. So I'll just keep rescuing the ones I can, and vacuuming the ones I can't.
Besides, they are the cleanest, least-creepy, and prettiest bugs there are.
