Final answer:
Residual and larvicidal insecticides, biological control, baits, electric grids, and traps are examples of management and elimination methods for flies.
Step-by-step explanation:
True
Residual and larvicidal insecticides, biological control, baits, electric grids, and traps are all examples of management and elimination methods for flies. These methods have been proven to be effective in controlling fly populations and reducing insect resistance. For example, biological control involves the use of beneficial insects, cultivated predators, and natural or non-toxic pest control products to reduce fly populations. Electric grids and traps are also commonly used to catch and eliminate flies.
