You probably don’t need anyone else nagging you about this, but: clean your dishes! Apartment buildings and high-density housing complexes require constant pest control attention simply because of the sheer quantity of people living in one relatively small space. Furthermore, not every resident has pristine sanitation habits, and many tenants tend to leave food and liquids lying around — especially in the kitchen sink. If you want your apartment community to avoid a pest problem, educate yourself and your neighbors about how to keep the insect and rodent population to a minimum in your apartment complex.
