Which sanitation method eliminates breeding sites for pests?

Eliminating breeding sites for pests is a crucial part of pest management and sanitation. The method of reducing water access is effective because many pests, such as mosquitoes and flies, require water to breed. By minimizing standing water and ensuring that areas are dry, you disrupt the breeding cycles of these pests. This makes it more difficult for them to reproduce and thrive in the environment.

In contrast, increasing food storage might inadvertently attract pests if the food is not stored properly. Avoiding waste disposal can lead to an accumulation of organic material, creating ideal conditions for pests to breed. Leaving food uncovered directly provides access to food sources for pests, thus encouraging their presence. Thus, reducing water access directly impacts the ability of pests to breed, making it the most effective sanitation method among the given options.
