Rodents enter buildings through small gaps in doors, utility penetrations and damaged vents. Seal openings with durable materials, fit door sweeps, store food in closed containers and clean crumbs from break areas. Keep storage off the floor and inspect deliveries for signs of activity. Avoid leaving waste overnight. If droppings or gnaw marks appear, do not sweep them dry; follow public-health cleaning guidance and contact a pest-control professional for safe removal and exclusion advice.
Prevention checklist
- Keep food and waste managed properly.
- Inspect for moisture, gaps and signs of pest activity.
- Use pest-control products only as directed on their labels.
When to call a professional
If the problem keeps returning, affects a business or involves hidden damage, arrange an inspection with a qualified pest-management provider. Ask for clear preparation instructions, safety guidance and follow-up recommendations.
