A wildlife guard apparatus for an electrical insulator body includes at least one guard assembly. Each guard assembly includes a guard member and a base wall member secured to the guard member. The at least one guard assembly is configured or configurable to form an enclosure defining a chamber. In the enclosure configuration, the at least one guard member defines an end opening communicating with the chamber and the at least one base wall member extends across the end opening to close at least a portion thereof. The enclosure is configured to receive the insulator body such that the insulator body includes a first portion and a second portion, the first portion extending through the end opening and adjacent the at least one base wall member, and the second portion being disposed in the chamber. The at least one guard member is formed of a first material and the at least one base wall member is formed of a second material that is softer than the first material.
