Being that the Cockroach is one of the hardiest creatures. They can resist Radiation at 15 times the level a human can tolerate, they can live headless for a week and can hold their breath for 45 minutes, they can go without food for five weeks and still survive-so what exactly is in roach spray and shouldn't that be extremely poisonous to us?
