Final answer:
To protect against disease-bearing insects, using insect repellent, mosquito nets, and managing the environment by removing breeding sites and targeted pesticide applications are effective strategies.
Step-by-step explanation:
Protecting against disease-bearing insects is an important public health measure. Three effective methods include:
Insect repellent: Applying repellent on skin and clothing to deter insects.
Mosquito nets: Using bed canopies, like mosquito nets, especially during the night to prevent mosquito bites.
Environmental management: Eliminating standing water and other breeding sites to reduce insect populations, and using targeted pesticide applications to preserve natural insect predators.
These strategies not only help in controlling insect populations but also contribute to protecting surroundings and lowering costs associated with disease management. Moreover, the use of biological control tools can enhance the effectiveness of these methods.
