What scenario can lead to pest infestation?

Storing recyclables in paper bags can lead to pest infestation due to the nature of paper as a material. Paper is typically more permeable and less resistant to moisture and damage compared to metal or plastic. If paper bags are exposed to moisture or become torn, they can easily attract insects and other pests looking for food sources or nesting materials. This environment can promote a breeding ground for pests.

In contrast, metal containers and sealed plastic bags are generally more pest-proof, providing a secure barrier that helps keep pests out. Additionally, separating food from waste is a practice that aids in pest control by minimizing attraction, as food scraps left alongside waste can lure pests. Thus, the conditions surrounding the storage method directly contribute to the likelihood of pest problems in a given scenario.
