What is a common characteristic of false bottom cabinets that may harbor insects?

False bottom cabinets often feature a design that creates hidden spaces or compartments, making them effective at concealing pest entry points. This characteristic is significant because pests such as roaches or ants can easily take advantage of these concealed spaces to nest or find access to food and moisture sources. The design of these cabinets may hide gaps or openings where pests can enter, leading to infestations that might go unnoticed until they become severe.

The other choices do not accurately describe the primary concern associated with false bottom cabinets in the context of pest control. While some cabinets may be decorative, their functionality regarding pest concealment is more pertinent. Being made of metal is irrelevant to the issue of pest access, as various materials can serve the same purpose in concealing entry points. Lastly, while false bottom cabinets might be used for food storage, this does not directly relate to their capacity to hide openings for pests. The focus on entry points better highlights the pest management consideration necessary for these cabinet types.
