Follow air movement and heat. That’s the best method for identifying rodent entry points. In my experience, this technique is easier than looking for rub marks, droppings and nesting locations, and paints a better picture for the customer and the technician. Rodents need heat to survive and thrive when outside temperatures fall. Keep the following in mind:
- Inspect areas where warm air escapes the building from vents, around pipes, on roofs and under doorways.
- Excess debris from trash or leaves and overgrowth from groundcover provide protective cover and warmth for nesting areas.
- Seam lines of buildings (along the concrete or asphalt) will hold heat from the sun, and are great run paths for rats and mice. Follow those lines.
- Heat-sensing cameras are a useful tool, and give you and your customer a good overview of potential entry points, especially in winter. Sealing and controlling heat from escaping a building helps prevent rodents, and adds value to your service.
