Do roaches, waterbugs, whateva you wanna call em do us any good? What is their purpose?

Question

once again I realize there purpose to survive like all living beings, but do they do us humans any good? Or are they just here to terrorize us??

Answer 1

Roaches do not do humans any good. They spread disease. Out in the wild, where they belong, they do a great deal of good. They help clean up dead animals and plant matter, and they are a source of food for lots of other critters.

Answer 2

Just part of the food chain that's all.

Regards

Answer 3

Their purpose is to survive, and feed other pests.They are immune to atomic bombs, and are getting good at resisting sprays and poisons. They have no redeeming value, and they are not even attractive in a display board.If you kill one, it can still lay an egg pouch, so kill one and get forty.
