Which of the following methods can be used to treat mosquito infestations?

Source reduction is an effective method for controlling mosquito infestations because it focuses on eliminating or managing the breeding sites where mosquitoes thrive. Mosquitoes require standing water to reproduce, so controlling areas that collect water—such as clogged gutters, discarded tires, or any receptacles that can hold water—is crucial. By removing these potential breeding grounds, the overall mosquito population can be significantly reduced.

While insect growth regulators can also be used to manage mosquito populations by interrupting their developmental processes, source reduction is more direct and generally more effective since it tackles the root cause of the infestation. Fumigation is typically not a suitable method for treating mosquitoes, as it is primarily used for pests within confined spaces, and it does not address the breeding cycle. Planting repellent plants is a more passive approach and may not be sufficient to manage existing infestations effectively.
