Cockroach memes

I eat cockroaches.

One day a father and a daughter were at a park. The daughter accidentally kills a butterfly. The father says, "Just because you killed the butterfly, you don't get butter for a week."

They were there the next day, and the daughter kills a cockroach. The father laughs and says, "Nice try."

If dust mites are found in dust, bedbugs are found in beds, where are cockroaches found in?
