TW, you probably don't live in a city. But if you have been in those perfectly groomed suburbs you sometimes see little flags by the sidewalk with a kid and a dog in a big red circle with a line through it. Then in fine print underneath it reads keep off lawn, lawn chemical application. Where I live those flags are required for six MONTHS after the last application.

These flags. If you do more than a spot treatment in my city by law these flags must be posted, and in most cities, though mine has exceptionally long requirements.
No I never heard of this before either. Amazing.
