Welcome to Rodent Barriers, LLC

At Rodent Barriers, LLC, we are dedicated to providing top-of-the-line rodent intrusion barrier, and copper wire anti theft solutions specifically designed for the department of transportation’s signal and light poles. Our journey began as collaboration with the Minnesota Department of Transportation (MnDOT), and has since expanded to gain approval in multiple states, with even more pending evaluations.

Our commitment to excellence is demonstrated through our superior design. For our Rodent Intrusion Barriers, we use flexible LDPE plastic, which offers a user-friendly, easy-to-install rodent barrier compared to traditional rigid PVC or wire mesh alternatives. What really makes our design unique though, is our patented Spring Loaded Clip, which provides constant tension and creates a consistent tight fit for unparalleled protection in any temperatures.

Our copper wire anti theft devices will virtually eliminate copper wire theft in DOT lighting and signal bases.

We also offer other creative solutions in our Luminaire Tenon Wire Grips & Rodent Barrier and our Silicone Putty options. Check out our entire product line up and contact us with any questions!
