ELI5: Why do cockroaches flip when they die?
gpt
Roaches killed by Insecticide tend to have muscle spasms that roll them onto their backs, and like certain species of turtles, they have trouble rolling back onto their front on smoother surfaces - especially when weakened by poison. 

Not all of them die on their backs, and they're far more likely to indoors.
