Question

why has it been said that only insects directly complete with humans for food?

Answer 1

Most insects have hairy cavity under their legs. Wherever they sit, they pick up germs from that place and they also feed in dirty places. Now, when they come and sit on our food, they spoil it as the dirt and feels on their feet land on our food and furthermore they vomit out all that they ate on our food. This contaminates our food. If unknowingly, this food goes in our body then, we get serious diseases like dysentery, cholera, diarrhoea, etc. Some of the most common insects are housefly, mosquitoes and cockroaches.
This way they directly compete with Humans for food.
