Question

What are the effects of harmful insects and animals to people and properties?

Answer 1

Harmful insects kill millions of people every year both indirectly and directly.  Besides deadly insects, mosquitoes and flies transmit diseases that sicken and kill.  Malaria is one of the best know of these diseases but there are many more.  Insects consume or damage many of our food crops which in the less developed countries leaves to malnutrition and make many people, especially children, less able to fight off many pathogens.

Harmful animals are more direct and affect fewer people.  Besides the obvious harm of animals that consume people,  Animal can consume crops grown for people or damage stored food.  Mice and rats have been a problem in stored grain throughout history.  Some animals such as rats also transmit disease such as bubonic plague.
