An additional technique to deter rodent occupation is to make the area less level, by securing an object underneath the Auto Tack Mat. Non-level areas are less desirable to occupy, and by adding slope to the inhospitable surface of the Auto Tack Mat you can further reduce the likelihood of rodent occupation. This tactic can be particularly useful in protecting wiring located next to a level area.
An object of about 1½ inches in height is typically sufficient to create the needed slope. Examples of objects that may be useful to create slope include a small piece of wood or a metal corner brace (available at hardware stores).
