What is a primary control method for preventing mite issues in landscaping?

The primary control method for preventing mite issues in landscaping involves implementing cultural practices, biological controls, and chemical interventions effectively to manage pest populations. Among the options provided, spraying the perimeter with miticides serves as a direct action to control and prevent mite infestations. This approach targets specific areas where mites are most likely to enter and breed, offering a protective barrier against their establishment in the landscape.

Using miticides is particularly effective when an existing mite population needs regulation or when preventive measures are necessary before an infestation occurs. It's crucial to apply these treatments strategically to minimize impact on non-target organisms and maintain ecological balance.

Regular watering can promote plant health, which indirectly supports plants in withstanding pest pressures but does not specifically target mites. Planting resistant plants can help minimize mite problems by selecting species that are less favorable to them, but this is more of a long-term strategy. Using gravel in gardens may improve drainage, but it does not offer significant deterrence against mite populations compared to direct miticide applications. Therefore, using miticides on the perimeter effectively addresses the immediate threat posed by mites in landscaping.
