South Florida’s sunshine and plentiful resources create an ideal habitat—not just for residents and visitors seeking warm weather, but for opportunistic rodents as well. Mice and rats, with their gnawing teeth and furry bodies, are increasingly finding their way into homes and warehouses in South Florida, seeking food and shelter. While they may seem harmless, their presence poses serious health risks and potential property damage.

Understanding their habits, the dangers they pose, and how to prevent and control them is essential for every homeowner and business owner in South Florida.
