Protect Power Lines and Transformers with Critter Guard's Line and Pole Guards

Located in Columbia, MO, Critter Guard is a humane wildlife control product developer specializing in protecting electric power and communication lines, transformers, switches, and substations for utility companies and homeowners across the United States and international markets. Animal related power outages cost billions of dollars in damages each year in the United States, and are one of the most common causes of outages internationally. With this in mind, we created products specifically designed to humanely deter squirrels and other animals (i.e., critters) from accessing electric power and data communication lines, substations, and transformers resulting in reduced loss of life for animals while keeping power and/or information flowing safely.

Keep squirrels and other rodents from using overhead lines to access your home
  • The City purchased Line Guard specifically because we were having repeated problems with squirrels accessing the substation from the overhead lines. We've had no further occurrences since we installed Line Guard. I'd recommend Line Guard without hesitation.

  • We were having repeated squirrel issues at this location until we installed the Critter Guard materials. It has now been a year without that first problem. The guards do not clutter up the switch location and do not detract from the appearance of the line.

  • The positive results at Cordrey lead Entergy Texas personnel to believe the investment and work to put spinners in place at substations throughout the service territory will pay off in fewer outages for customers.

  • We have used Critter Guard's Line Guard product for better than six years on Illinois and Missouri overhead power lines near substations. The Line Guard helps us prevent squirrels from gaining access to our substations on overhead lines. We have also used the Pole Guard on wooden poles near substations to establish a barrier to squirrels that approach overhead conductors from the ground. Our objective is to maintain high service reliability by eliminating outages and contain costs by reducing equipment damage caused by squirrels.
