Critter Guard developed animal mitigation products to protect substations and transformers from squirrel power outages. Our barriers keep squirrels and other rodents out of substations by blocking their ability to run across power lines, and up utility poles. The largest power companies use Critter Guard and are proven for years of service in all weather conditions.

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.
