In combination, a pedestal enclosure for enclosing above ground extensions of underground cables, which defines a cable holding chamber having an open bottom adapted for extension into the ground for access to underground cables, and in said holding chamber, and blocking the bottom thereof a rigid, foamed, cell-developed, insulating, polymeric, thermosetting, plastic material, in which a substantial number of said cells contain encapsulated therein an effective gaseous rodent retardant. A method of retarding rodent access to the interior cable holding chamber of a cable pedestal having an open bottom, said method comprising: installing a cable pedestal having an open bottom; mixing at least two normally liquid organic chemical ingredients capable upon exothermic reaction of providing a rigid, thermosetting, foamed, cell-developed, polymer, at least one of said ingredients containing therein a normally liquid rodent retardant capable of volatilization to a gaseous state upon the exothermic, thermosetting reaction of said other ingredients, and pouring said mixed ingredients into said holding chamber of said pedestal at a location so as to block access to the interior thereof through said open bottom. A rigid, foamed, cell-developed, thermally set, polymeric material, and encapsulated in a substantial number of the cells thereof, a gaseous state rodent retardant for release to the environment upon rupture of said cells. A kit for forming a rigid, foamed, cell-developed, polymeric, plastic material in which a substantial number of the cells encapsulate an effective volatilized rodent retardant for release upon rupture of said cells, comprising: a first container with liquid isocyanate, a second container with a poly ether, at least one of said containers having a blowing agent therein, and at least one of said containers having a normally liquid rodent retardant therein which is capable of volatilization upon mixing of the ingredients of said containers, and a flexible shipping bag containing said first and second containers. A method of encapsulating, in a gaseous state, a normally liquid rodent retardant in the cell structure of a rigid, foamed, cell-developed, thermosetting, material formed by mixing two normally liquid chemical ingredients which react exothermally to provide a thermoset material, comprising: adding to one of said chemical ingredients used in the preparation of said foamed material a normally liquid rodent retardant which is miscible therewith, and which is capable of volatilization at the exothermic reaction temperature achieved by mixing said two normally liquid ingredients; adding said one ingredient containing said rodent retardant to the other of said ingredients; whereby said exothermic reaction forms said rigid, foamed, cell-developed, thermosetting material, and said retardant volatilizes and is trapped in said cells of material for release upon subsequent cell rupture.
