How are insects harmful to us humans?

Answer:
Insects harm us in many ways. Insects, such as flies and mosquitoes, spread diseases like malaria. Bees and wasps (also hornets) can sting us and sometimes, kill us. But insects help us in many ways too, such as pollinating and the control of pests in the house.
