Trap-guard for vermin repellant destruction

A barrier against vermin crawling along an elongated structure, the barrier comprising:

• an outer shell having a fully closed vermin impervious end wall and a generally continuous side wall assembly defining a cavity, the continuous side wall further defining a fully open, unobstructed, barrier-free access opening axially opposite the closed end wall, said access opening defined by an end of the generally continuous side wall;
• mounting means for connecting the outer shell to the elongated structure with the elongated structure extending generally axially through said outer shell, said mounting means further including means for preventing relative motion between the outer shell and the elongated structure;
• and,
• a pesticide disposed in the cavity for creating a vermin-deterring environment inside the cavity.
