Prevention
Prevention focuses on reducing contact with wild rodents and avoiding dust from contaminated urine, droppings, saliva, and nesting materials.
Keep rodents out by sealing openings, removing food sources, and reducing shelter.
Use safe wet-cleaning methods rather than sweeping or vacuuming dry droppings.
Follow local public health or occupational safety guidance for heavy infestations or workplace exposures.
Air out enclosed spaces before cleaning, look for evidence of rodent activity, and clean contaminated materials using disinfectant-based methods.
Store food in rodent-proof containers and address entry points that allow rodents into buildings.
Heavy infestations, contaminated ventilation systems, and workplace cleanup may require professional pest control, public health guidance, or occupational safety support.
